Persistent symptoms after COVID-19 in children and adolescents from Argentina.

OBJECTIVES: Although long COVID-19 is widely recognized in adults, less information is available about this condition in children, especially in developing countries. Here, we studied the long-term symptoms of SARS-CoV-2 infection beyond 3 months and the associated risk factors in a pediatric population. METHODS: This observational study included 639 Argentinian children and adolescents with previously confirmed COVID-19 from June 2020-June 2021 and 577 children without previous COVID-19. Parents completed a survey about symptoms that their child had for >3 months after the diagnosis of SARS-CoV-2 infection. RESULTS: At least one persistent symptom was observed more frequently in children with previous COVID-19 than in the non-COVID-19 group (34% vs 13%, P <0.0001). SARS-CoV-2 infection increased the risk of headache, dizziness, loss of taste, dyspnea, cough, fatigue, muscle pain, and loss of weight by three- to seven-fold. The loss of smell was only reported in infected children. After controlling for the other variables, older age, symptomatic COVID-19, and comorbidities were independent predictors of long-term symptoms. CONCLUSIONS: One-third of children experienced persistent symptoms after COVID-19. Older age, symptomatic infection, and comorbidities were shown to be risk factors for long COVID-19. Pediatric long COVID-19 is a new condition that requires further investigation.

Long-Term Symptoms after Mild Coronavirus Disease in Healthy Healthcare Professionals: A 12-Month Prospective Cohort Study.

The coronavirus disease 2019 (COVID-19) pandemic has changed the course of human history and killed millions of people worldwide. Its long-term consequences remain uncertain. This study aimed to describe the short- and long-term symptoms of COVID-19 among individuals in Goiás, central Brazil, who experienced acute mild or non-symptomatic SARS-CoV-2 infection during the first wave of the pandemic. This prospective cohort study included 110 healthcare workers, 18 safety workers, and 19 administrative support workers, who were followed up for 12 months after the onset of COVID-19. Most participants were healthy adult female healthcare professionals. At the onset of infection, the major symptoms were headache, myalgia, nasal congestion, cough, coryza, anosmia, ageusia, sore throat, fatigue, diarrhea, and dyspnea. Furthermore, 20.3% of the participants had three or more COVID-19 symptoms that persisted for at least 12 months. These included coryza, congestion, hair loss, sore throat, headache, myalgia, cough, memory loss, anosmia, and fatigue. This study revealed a high prevalence of persistent symptoms of COVID-19 in healthy individuals from central Brazil, which may present an additional burden on healthcare services. Further studies are required to investigate the sequelae of COVID-19 over periods greater than 12 months.

Chronic respiratory diseases and respiratory symptoms after a mining dam rupture: Brumadinho Health Project.

OBJECTIVE: To identify factors associated with asthma and chronic obstructive pulmonary disease (COPD) and respiratory symptoms, in Brumadinho, state of Minas Gerais, Brazil, after a dam rupture. METHODS: This is a cross-sectional study, including a representative sample of adults (aged 18 years and over) in the municipality. Associations were assessed between dependent variables (medical diagnosis of asthma and COPD; symptoms of wheezing, dry cough, and nose irritation) and exploratory variables (sex, age group, smoking habit, having worked at Vale S.A. company before the dam rupture, time and area of residence in relation to the dam rupture). Logistic regression models with odds ratio (OR) calculation and 95% confidence interval were used. RESULTS: We identified a prevalence of 7.2% of asthma; 3.5% of COPD; 8.8% of wheezing; 23.6% of dry cough; and 31.8% of nose irritation. We observed a greater chance of asthma among women and residents in the affected and mining regions, while a greater chance of COPD was observed in smokers and in those with longer time of residence in the municipality. Among the symptoms, we verified a higher chance of nose irritation among women, while a higher chance of wheezing and dry cough were found among smokers (current and former). Residents of regions affected by the mud reported a greater chance of presenting all the analyzed symptoms. Conversely, level of education was negatively associated with wheezing and dry cough. CONCLUSION: We found respiratory changes and identified the groups most vulnerable to developing them, which could contribute to directing actions to reduce the population's respiratory problems.

Epidemiological and clinical characteristics of survivors of SARS-COV-2 infection: A descriptive study. / Características epidemiológicas y clínicas de sobrevivientes a infección por SARS-CoV-2: estudio descriptivo.

Introduction: In March 2020, the World Health Organization (WHO) declared a pandemic for coronavirus 19. Typical symptoms were fever, cough, asthenia, dyspnea, and muscle pain. Pulmonary and central nervous system compromise presented challenging characteristics for healthcare physicians. The objectives of this study were to identify epidemiological and clinical characteristics of SARS-COV-2 infection survivors in a region of Argentina and to determine differences between gender, age groups, year of infection, and evolution time since diagnosis. Methods: A descriptive and analytical cross-sectional observational study was carried out. A self-administered questionnaire was applied, which was available between August and December 2021. Results: Among 1868 individuals included, the mean age was 39.4 ± 13.9 years, and 72.8% were female. Arterial hypertension was the most frequent comorbidity (11.7%). The majority were outpatients (81.9%). The most frequent presentation symptoms at all ages were asthenia (83.7%), fever (54.9%), headache (60.8%), anosmia (64.8%), ageusia (53.2%), cough (54.4%) and myalgias (53.7%). For the 18 to 29 years old age group, the most prevalent presentation symptoms were: headache (69.4%), anosmia (69.1%), ageusia (60.2%), odynophagia (45%), and rhinitis/nasal congestion (46.9%). In the 30 to 64 years old age group, there was a higher prevalence of myalgias (55.8%), arthralgias (41%), and concentration/memory disorder (28.3%). Male showed higher prevalence of fever (64.9% versus 51.1%; p < 0.001) and pneumonia (23.5% versus 13.4%; p < 0.001). After 12 weeks from diagnosis, 38.1% of patients persisted with asthenia, 23.6% with anosmia/dysosmia, and 21.2% with concentration/memory disorders. Conclusions: Systemic symptoms were common to all age groups with coronavirus 19 disease; however, younger, and intermediate age groups presented a higher prevalence of central nervous system symptoms such as anosmia and cognitive disorders, respectively. Symptoms beyond 12 weeks of diagnosis reached slightly more than 10% of the participants.

Introducción: En marzo de 2020 la enfermedad por coronavirus 19 fue declarada pandemia por la Organización Mundial de la Salud. Los síntomas más comunes fueron fiebre, tos, astenia, disnea y dolor muscular. Los compromisos pulmonar y del sistema nervioso central presentaron características desafiantes para los médicos asistenciales. Los objetivos del estudio fueron conocer las características epidemiológicas y clínicas de sobrevivientes a infección por SARS-CoV-2 en una región de Argentina, y determinar las diferencias entre género, grupos etarias, año de contagio, tiempo de evolución desde el diagnóstico. Métodos: Se realizó un estudio observacional descriptivo y analítico de corte transversal. Se aplicó un cuestionario auto administrado, que estuvo disponible entre agosto y diciembre de 2021. Resultados: La media de edad fue de 39,4 ± 13,9 años, el 72,8% fueron mujeres. La comorbilidad más frecuente fue hipertensión arterial (11,7%). La mayoría de los pacientes fueron ambulatorios (81,9%). Los síntomas de presentación más frecuentes a cualquier edad, fueron astenia (83,7%), fiebre (54,9%), cefalea (60,8%), anosmia (64,8%), ageusia (53,2%), tos (54,4%) y mialgias (53,7%). Para el grupo de 18 a 29 años los síntomas de presentación más prevalentes fueron cefalea (69,4%), anosmia 69,1%), ageusia (60,2%), odinofagia (45%) y rinitis/congestión nasal (46,9%). En el grupo de 30 a 64 años se observó mayor prevalencia de mialgias (55,8%), artralgias (41%), falta de concentración/memoria (28,3%). Los hombres mostraron más prevalencia de fiebre (64,9% versus 51,1%; p < 0,001) y neumonía (23,5% versus 13,4%; p < 0,001). Luego de las 12 semanas del diagnóstico 38,1% de los pacientes persistían con astenia, 23,6% con anosmia/disosmia y 21,2% con trastornos de concentración/memoria. Conclusiones: La enfermedad por coronavirus 19 presenta un patrón de síntomas sistémicos común a todos los grupos etarios. No obstante, los grupos más jóvenes presentan más prevalencia de síntomas de afección del sistema nervioso central como la anosmia y los grupos intermedios, mayor prevalencia de trastornos cognitivos. Los síntomas más allá de las 12 semanas del diagnóstico alcanzaron a algo más del 10% de los participantes.

Risk factors associated with the severity of COVID-19 in a region of the Brazilian Amazon.

The Brazilian Northern region registered a high incidence of COVID-19 cases, particularly in the state of Pará. The present study investigated the risk factors associated with the severity of COVID-19 in a Brazilian Amazon region of 100,819 cases. An epidemiological, cross-sectional, analytical and demographic study, analyzing data on confirmed cases for COVID-19 available at the Brazilian Ministry of Health's surveillance platform, was conducted. Variables such as, municipalities of residence, age, gender, signs and symptoms, comorbidities were included and associated with COVID-19 cases and outcomes. The spatial distribution was performed using the ArcGIS program. A total of 100,819 cases were evaluated. Overall, patients had the mean age of 42.3 years, were female (51.2%) and with lethality reaching 4.79% of cases. Main symptoms included fever (66.5%), cough (61.9%) and sore throat (39.8%). Regarding comorbidities, most of the patients presented cardiovascular disease (5.1%) and diabetes (4.2%). Neurological disease increased risk of death by nearly 15 times, followed by obesity (5.16 times) and immunodeficiency (5.09 time). The municipalities with the highest incidence rate were Parauapebas, Canaã dos Carajás and Jacareacanga. Similarity between the Lower Amazon, Marajó and Southwest mesoregions of Pará state were observed concerning the highest morbidity rates. The obtained data demonstrated that the majority of cases occurred among young adults, females, with the classic influenza symptoms and chronic diseases. Finally, data suggest that the highest incidences were no longer in the metropolitan region of the state. The higher lethality rate than in Brazil may be associated with the greater impacts of the disease in this Amazonian population, or factors associated with fragile epidemiological surveillance in the notification of cases of cure.

Factors associated with mortality in patients hospitalized with COVID-19: A prospective cohort in a Peruvian national referral hospital. / Factores asociados a mortalidad en pacientes hospitalizados con COVID-19: cohorte prospectiva en un hospital de referencia nacional de Perú.

OBJECTIVES: To describe and assess clinical characteristics and factors associated with mortality in adult patients with COVID-19 admitted to a national referral hospital in Peru. METHODS: We conducted a prospective cohort study that included hospitalized patients older than 18 years with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection diagnosis. Patients with a positive rapid serological test on admission but no respiratory symptoms nor compatible images were excluded. We collected the data from clinical records. RESULTS: A total of 813 adults were included, 544 (66.9%) with confirmed COVID-19. The mean age was 61.2 years (standard deviation: 15.0), and 575 (70.5%) were male. The most frequent comorbidities were hypertension (34.1%) and obesity (25.9%). On admission, the most frequent symptoms were dyspnea (82.2%) and cough (53.9%). A total of 114 (14.0%) patients received mechanical ventilation, 38 (4.7%) were admitted to the intensive care unit, and 377 (46.4%) died. The requirement for ventilatory support, greater lung involvement, and inflammatory markers were associated with higher mortality. It was found that for every 10-year age increase, the risk of dying increased 32% (relative risk: 1.32; 95% confidence interval: 1.25 to 1.38). Those who were admitted to the intensive care unit and and were placed on mechanical ventilation had 1.39 (95% confidence interval: 1.13 to 1.69) and 1.97 (95% confidence interval: 1.69 to 2.29) times the risk of dying compared to those who did not, respectively. CONCLUSION: We found a high mortality rate among hospitalized patients associated with older age, higher inflammatory markers, and greater lung involvement.

MÉTODOS: Se realizó un estudio de cohorte prospectivo. Se incluyó a pacientes mayores de 18 años hospitalizados con el diagnóstico de infección por coronavirus 2 del síndrome respiratorio agudo severo (SARS-CoV-2). Se excluyó a quienes ingresaron con prueba rápida serológica positiva al ingreso, sin clínica sugestiva ni imágenes compatibles. Los datos se recolectaron a partir de la historia clínica. RESULTADOS: Se incluyó un total de 813 adultos, 544 (66,9%) tuvieron COVID-19 confirmado. La media de la edad fue de 61,2 años (desviación estándar: 15) y 575 (70,5%) fueron de sexo masculino. Las comorbilidades más frecuentes fueron hipertensión arterial (34,1%) y obesidad (25,9%). Los síntomas más frecuentes al ingreso fueron disnea (82,2%) y tos (53,9%). Un total de 114 (14%) pacientes recibieron ventilación mecánica, 38 (4,7%) ingresaron a unidad de cuidados intensivos y 377 (46,4%) fallecieron. Se asociaron a la mortalidad el requerimiento de soporte ventilatorio, el mayor compromiso pulmonar y los marcadores inflamatorios. Encontramos que por cada 10 años que aumentó la edad, el riesgo de morir se incrementó en 32% (riesgo relativo: 1,32; intervalo de confianza 95%: 1,25 a 1,38). Aquellos pacientes que requirieron ingreso a unidad de cuidados intensivos y ventilación mecánica tuvieron 1,39 (intervalo de confianza 95%: 1,13 a 1,69) y 1,97 (intervalo de confianza 95%: 1,69 a 2,29) veces el riesgo de morir, respectivamente. CONCLUSIÓN: La mortalidad encontrada en nuestro estudio fue alta y estuvo asociada a la edad, marcadores inflamatorios y compromiso respiratorio.

Clinical and epidemiological characteristics of children with SARS-CoV-2 infection: a case series in Sinaloa.

Background: The SARS-CoV-2 virus may affect both adults and children. Although COVID-19 has a lower prevalence in infancy and has been described as mild, the clinical characteristics may vary, and there is a possibility of complications. The objectives of this study were to describe the clinical and epidemiological aspects of confirmed COVID-19 pediatric cases in the state of Sinaloa, Mexico, during the first 3 months of the pandemic, and children admitted with COVID-19 to a secondary hospital. Methods: This case series includes all patients with SARS-CoV-2 infection confirmed by PCR (polymerase chain reaction) test, identified in the state epidemiological surveillance system (SISVER) between March 1 and May 31, 2020. Confirmed patients admitted to the Sinaloa Pediatric Hospital (HPS) in the same period are also described. Results: Fifty-one children with SARS-CoV-2 were included, of which ten were admitted to the HPS. The median age was 10 years. The more frequent symptoms were fever (78%), cough (67%), and headache (57%). Most cases were mild or asymptomatic. Three patients with comorbidities died. Only four of ten patients identified in HPS were admitted with the diagnosis of possible COVID-19. Conclusions: SARS-CoV-2 infection in children was mostly mild or asymptomatic, and the clinical presentation varied. There is a possibility of complications, especially in children with comorbidities.

Introducción: El SARS-CoV-2 puede afectar tanto a adultos como a niños. Aunque la COVID-19 presenta menor prevalencia en la infancia y se ha descrito como leve, las características clínicas pueden ser variables y existe la posibilidad de complicaciones. Los objetivos de este estudio fueron describir las características clínicas y epidemiológicas de los casos pediátricos confirmados en el Estado de Sinaloa, México, durante los primeros 3 meses de la pandemia, y de los niños con COVID-19 internados en un hospital de segundo nivel. Métodos: Esta serie de casos incluyó pacientes con infección por SARS-CoV-2 confirmados por prueba de reacción en cadena de la polimerasa (PCR), identificados en el Sistema de Vigilancia Epidemiológica de Enfermedades Respiratorias (SISVER) del 1 de marzo al 31 de mayo de 2020. Se describen también las características de todos los niños confirmados en el Hospital Pediátrico de Sinaloa (HPS) en las mismas fechas. Resultados: Se incluyeron 51 niños con infección por SARS-CoV-2, de los cuales 10 fueron internados en el HPS. La mediana de edad fue de 10 años. Los síntomas más frecuentes fueron fiebre (78%), tos (67%) y cefalea (57%). La mayoría de los casos fueron leves o asintomáticos. Tres pacientes con comorbilidad fallecieron. Solo cuatro de diez pacientes identificados en el HPS ingresaron bajo sospecha de COVID-19. Conclusiones: La infección por SARS-CoV-2 en los niños fue, en su mayoría, asintomática o leve, y la presentación fue variable. Existe la posibilidad de que se produzcan complicaciones, principalmente en niños con comorbilidad.

Prevalence of potential respiratory symptoms in survivors of hospital admission after coronavirus disease 2019 (COVID-19): A systematic review and meta-analysis.

Knowledge on the sequelae of Coronavirus Disease 2019 (COVID-19) remains limited due to the relatively recent onset of this pathology. However, the literature on other types of coronavirus infections prior to COVID-19 reports that patients may experience persistent symptoms after discharge. To determine the prevalence of respiratory symptoms in survivors of hospital admission after COVID-19 infection. A living systematic review of five databases was performed in order to identify studies which reported the persistence of respiratory symptoms in COVID-19 patients after discharge. Two independent researchers reviewed and analysed the available literature, and then extracted and assessed the quality of those articles. Of the 1,154 reports returned by the initial search nine articles were found, in which 1,816 patients were included in the data synthesis. In the pooled analysis, we found a prevalence of 0.52 (CI 0.38-0.66, p < 0.01, I2 = 97%), 0.37 (CI 0.28-0.48, p < 0.01, I2 = 93%), 0.16 (CI 0.10-0.23, p < 0.01, I2 = 90%) and 0.14 (CI 0.06-0.24, p < 0.01, I2 = 96%) for fatigue, dyspnoea, chest pain, and cough, respectively. Fatigue, dyspnoea, chest pain, and cough were the most prevalent respiratory symptoms found in 52%, 37%, 16% and 14% of patients between 3 weeks and 3 months, after discharge in survivors of hospital admission by COVID-19, respectively.

Clinical presentation and outcomes of the first patients with COVID-19 in Argentina: Results of 207079 cases from a national database.

BACKGROUND: There is limited evidence on the clinical characteristics of SARS-CoV-2 infection in Latin America. We present findings from a nationwide study in Argentina. RESEARCH QUESTION: What is disease severity measures and risk factors are associated with admission to an intensive care unit and mortality? STUDY DESIGN AND METHODS: Data were extracted from the COVID-19 database of the Integrated Argentina Health Information System, encompassing the period of March 3rd to October 2nd, 2020, using a standardized case report form that included information on contact history, clinical signs and symptoms, and clinical diagnosis. Information was collected at the initial site of care and follow-up conducted through calls by the regional healthcare authorities. A confirmed case of COVID-19 was defined as having a positive result through sequencing or real-time reverse-transcriptase polymerase chain reaction (RT-PCR) assay of nasal and pharyngeal swab specimens. RESULTS: RT-PCR testing was positive in 738,776 cases. Complete datasets were available for analysis in 207,079 cases. Mean age was 42.9±18.8 years, 50.0% were males. Frequent co-existing conditions included hypertension (19.2%), diabetes (9.7%), asthma (6.1%) and obesity (5.2%). Most common symptoms included fever (58.5%), cough (58.0%), headache (45.4%), and sore throat (42.1%). Death or ICU admission were independently associated with older age, male, coma, dyspnea or tachypnea, and seizures, with underlying co-morbidities such as immunodeficiency, chronic renal failure, and liver disease showing the strongest effects. INTERPRETATION: Most cases of COVID-19 diagnosed in Argentina were mild and had a favorable outcome, but fatality rates were relatively elevated. Risk factors for adverse outcome included older age, male sex, coma and seizures, and the concurrent presence of several morbidities. These data may be useful for healthcare providers and healthcare policy makers of low-middle income and Latin American countries to guide decisions toward optimized care during the pandemic.

Métodos: Esta serie de casos incluyó pacientes con infección por SARS-CoV-2 confirmados por prueba de reacción en cadena de la polimerasa (PCR), identificados en el Sistema de Vigilancia Epidemiológica de Enfermedades Respiratorias (SISVER) del 1 de marzo al 31 de mayo de 2020. Se describen también las características de todos los niños confirmados en el Hospital Pediátrico de Sinaloa (HPS) en las mismas fechas. Resultados: Se incluyeron 51 niños con infección por SARS-CoV-2, de los cuales 10 fueron internados en el HPS. La mediana de edad fue de 10 años. Los síntomas más frecuentes fueron fiebre (78%), tos (67%) y cefalea (57%). La mayoría de los casos fueron leves o asintomáticos. Tres pacientes con comorbilidad fallecieron. Solo cuatro de diez pacientes identificados en el HPS ingresaron bajo sospecha de COVID-19. Conclusiones: La infección por SARS-CoV-2 en los niños fue, en su mayoría, asintomática o leve, y la presentación fue variable. Existe la posibilidad de que se produzcan complicaciones, principalmente en niños con comorbilidad.

Clinical manifestations of COVID-19 in the general population: systematic review.

Clinical manifestations of COVID-19 are varied in the general population. This study aimed to systematize the literature regarding clinical manifestations of patients with confirmed COVID-19. A systematic review of the literature was conducted. A total of 8070 scientific productions were found in the databases. Among the studies, 184 met the initial inclusion criteria, with a total of 114,046 patients. After complete reading, 32 studies that did not report clinical manifestations were excluded. The 152 publications finally included a total of 41,409 individuals from at least 23 countries and 26 different clinical manifestations were reported. In percentage terms, 6 symptoms had a general prevalence greater than or equal to 25%, namely, fever (58.66%), cough (54.52%), dyspnea (30.82%), malaise (29.75%), fatigue (28.16%) and sputum/secretion (25.33%). Neurological symptoms (20.82%), dermatological manifestations (20.45%), anorexia (20.26%), myalgia (16.9%), sneezing (14.71%), sore throat (14.41%), rhinitis (14.29%), goosebumps (13.49%), headache (12.17%), chest pain (11.49%) and diarrhea (9.59%) were other common symptoms. Only one study reported dermatological manifestations. The least frequent sign/symptom was hemoptysis (1.65%). In studies with more than 100 patients, the 3 main symptoms were fever (57.93%), cough (54.21%), and dyspnea (30.64%). Dermatological manifestations do not appear among the main symptoms. The identification of all clinical manifestations of COVID-19 is essential for an early diagnosis and the adoption of preventive measures.

Description of patients with severe COVID-19 treated in a national referral hospital in Peru. / Caracterización de pacientes con COVID-19 grave atendidos en un hospital de referencia nacional del Perú.

In order to describe manifestations from patients with coronavirus disease 2019 (COVID-19), sociodemographic variables such as, previous medical history, clinical and radiological manifestations, treatments and evolution of patients were evaluated. This took place from March 6th to 25th, 2020, in the "Edgardo Rebagliati Martins" National Hospital in Lima. Seventeen patients were registered: 76% were male, with an average age of 53.5 years (range 25-94); 23.5% had returned from abroad; 41.2% were referred from other health facilities; 41.2% were admitted to mechanical ventilation; 29.4% (5 patients) died. The risk factors detected were: advanced age, arterial hypertension and obesity. The main symptoms detected were: cough, fever and dyspnea. Frequent laboratory findings were: elevated C-reactive protein and lymphopenia. The predominant radiological presentation was bilateral interstitial lung infiltrate. A first experience in the management of patients diagnosed with severe COVID-19 in Peru is reported.

Con el objetivo de describir las manifestaciones de pacientes con enfermedad por coronavirus 2019 (COVID-19), se evaluaron variables sociodemográficas, antecedentes, manifestaciones clínicas y radiológicas, tratamientos y evolución en pacientes que ingresaron por emergencia, del 6 al 25 de marzo de 2020, al Hospital Nacional Edgardo Rebagliati Martins en Lima. Se registraron 17 pacientes: el 76% eran varones, edad promedio de 53,5 años (rango de 25 a 94); el 23,5% había regresado del extranjero; 41,2% referido de otros establecimientos de salud; 41,2% ingresó a ventilación mecánica; falleció el 29,4% (5 pacientes). Los factores de riesgo detectados fueron adulto mayor, tener hipertensión arterial y obesidad; los principales síntomas, tos, fiebre y disnea; los hallazgos de laboratorio frecuentes, proteína C reactiva elevada y linfopenia; la presentación radiológica predominante, el infiltrado pulmonar intersticial bilateral. Se reporta una primera experiencia en el manejo de pacientes con diagnóstico de la COVID-19 grave en el Perú.

COVID-19 is rarely reported in children and they are mildly affected in most cases. The most common clinical presentation of COVID-19 is cough, fever and sore throat; severe cases show tachypnea. The course of the disease is from one to two weeks. Laboratory findings are nonspecific; lymphopenia, elevation of C-reactive protein and procalcitonin have been described. Early chest X-ray is usually normal, and the most common tomographic findings are consolidations with halo, ground-glass opacities and tiny nodules which mainly affects subpleural areas. Management of the disease is supportive; in severe cases, it should be focused on respiratory support. It is recommended to limit the handling of respiratory secretions and to follow the same preventive measures provided to adults.

La enfermedad del coronavirus 2019 (COVID-19) es poco frecuente en niños y su salud se ve poco comprometida en la mayoría de casos. La presentación clínica más común es tos, fiebre y eritema faríngeo, los casos graves suelen presentarse con taquipnea. El curso de la enfermedad es de una a dos semanas. Los hallazgos de laboratorio son inespecíficos, entre ellos, linfopenia, elevación de la proteína C reactiva y la procalcitonina. En fases iniciales, la radiografía torácica es usualmente normal, y los hallazgos tomográficos más comunes son consolidaciones con signo del halo, vidrio esmerilado y nódulos pequeños, que afectan principalmente las zonas subpleurales. El manejo es sintomático y, en los casos graves, debe estar enfocado a brindar soporte respiratorio. Se recomienda que la manipulación de las secreciones respiratorias sea limitada y que se tengan las mismas precauciones para evitar contaminación que en pacientes adultos.

[Clinical manifestations and course of the first six reported cases of COVID-19 in the medical doctors of Peru]. / Manifestaciones clínicas y evolución de seis primeros casos reportados de COVID-19 en personal médico de Perú.

INTRODUCTION: Health personnel, including physicians, are a fundamental part of the first line of defense against the SARS-CoV-2 pandemic. OBJECTIVE: To characterize the clinical manifestations and course of the first cases of contagion by SARS-CoV-2 in doctors of Peru. METHODOLOGY: We present a series of six cases of doctors infected by SARS-CoV-2, with confirmed positivity for COVID-19, showing the daily evolution from the diagnosis of the disease, its main signs and symptoms, evolution, and until the outcome in each case. RESULTS: Five were men. The median age was 28 years (interquartile range: 27 to 33). In three cases the physician worked more than 12 hours a day in emergency and hospitalization services and not wear a mask at all times. The most frequent symptoms were axillary temperature above 38°C, malaise, dry cough, and odynophagia (the latter in three of the cases). The diagnosis was made at a median of 3 days (interquartile range: 3 to 4 days). The symptoms that persisted the most were dry cough (present during ten days in four doctors). Dysgeusia was the only symptom with the most extended duration (15 days in only one doctor). In the six cases, the course was favorable. However, these doctors found it difficult to return to functions in their hospital centers adequately. DISCUSSION: Despite a small number of cases, it is the first report detailing the evolution of symptoms day by day, which can help for occupational health and even for case surveillance and monitoring.

INTRODUCCIÓN: El personal de salud, entre ellos los médicos, es parte fundamental en primera línea de defensa ante la pandemia de COVID-19, causada por SARS-Cov-2. OBJETIVO: Caracterizar la clínica y evolución de los primeros casos de contagio por coronavirus en médicos de Perú. METODOLOGÍA: Se presentan una serie de seis casos de médicos infectados por coronavirus, con positividad confirmada para COVID-19, mostrando la evolución diaria desde el diagnóstico de la enfermedad, sus principales signos y síntomas, la evolución de los mismos y hasta el desenlace en cada caso. RESULTADOS: De los casos estudiados, cinco fueron hombres, tenían una mediana de edad de 28 años (rango intercuartílico: 27 a 33). Tres de ellos trabajaban más de 12 horas al día en servicios de hospitalización y emergencia; y tres no contaban con mascarilla como método de protección personal. Los síntomas más frecuentes fueron la temperatura axilar superior a 38 grados Celsius, el malestar general, la tos seca y la odinofagia (este último en tres pacientes). En cuanto al diagnóstico con la prueba molecular, tuvo una mediana de tres días de demora (con rango: de 2 a 6 días). Los síntomas que más persistieron fueron la tos seca (presente durante 10 días en cuatro médicos), y la disgeusia como síntoma único, que tuvo la mayor duración (15 días en un solo médico). En los seis casos la evolución fue favorable. Sin embargo, aún se tienen deficiencias para la definición de reincorporación laboral a sus centros hospitalarios. DISCUSIÓN: A pesar de ser un número pequeño de casos, es el primer reporte en personal de salud y que detalla día a día la evolución de los síntomas de COVID-19. Esto puede servir para la salud ocupacional, e incluso como base para la vigilancia y monitorización de los casos en una población mayor.

Body mass index, asthma, and respiratory symptoms: a population-based study.

OBJECTIVE: To estimate the prevalence of respiratory symptoms and asthma, according to body mass index (BMI), as well as to evaluate factors associated with physician-diagnosed asthma, in individuals ≥ 40 years of age. METHODS: This was a population-based cross-sectional study conducted in Florianópolis, Brazil, with probability sampling. Data were collected during home visits. Demographic data were collected, as were reports of physician-diagnosed asthma, respiratory symptoms, medications in use, and comorbidities. Anthropometric measurements were taken. Individuals also underwent spirometry before and after bronchodilator administration. Individuals were categorized as being of normal weight (BMI < 25 kg/m2), overweight (25 kg/m2 ≥ BMI < 30 kg/m2), or obese (BMI ≥ 30 kg/m2). RESULTS: A total of 1,026 individuals were evaluated, 274 (26.7%) were of normal weight, 436 (42.5%) were overweight, and 316 (30.8%) were obese. The prevalence of physician-diagnosed asthma was 11.0%. The prevalence of obesity was higher in women (p = 0.03), as it was in respondents with ≤ 4 years of schooling (p < 0.001) or a family income of 3-10 times the national minimum wage. Physician-diagnosed asthma was more common among obese individuals than among those who were overweight and those of normal weight (16.1%, 9.9%, and 8.0%, respectively; p = 0.04), as were dyspnea (35.5%, 22.5%, and 17.9%, respectively; p < 0.001) and wheezing in the last year (25.6%, 11.9%, and 14.6%, respectively; p < 0.001). These results were independent of patient smoking status. In addition, obese individuals were three times more likely to report physician-diagnosed asthma than were those of normal weight (p = 0.005). CONCLUSIONS: A report of physician-diagnosed asthma showed a significant association with being ≥ 40 years of age and with having a BMI ≥ 30 kg/m2. Being obese tripled the chance of physician-diagnosed asthma.
