RESUMEN
Geographical and racial factors constitute important distinctions between Kawasaki disease (KD) and multisystem inflammatory syndrome in children (MIS-C), but no study has been conducted in Vietnam. Forty-one children with KD from January 2018 to July 2020 and 42 with KD/MIS-C from August 2020 to December 2022 were included in this study. Of the patients, 52.3% were aged between 12 and 35 months. Only two were aged over 5 years, and both were belong to the KD/MIS-C group. A 59.5% of the patients were male. Apart from fever, all symptoms tended to be more frequent in patients with KD/MIS-C. The prevalence of diffuse skin rash, hand and foot edema or erythema and gastrointestinal signs was significantly higher in patients hospitalized with KD/MIS-C. There was no significant difference in laboratory findings between the two groups. Coronary artery dilation was more frequently observed in patients with KD/MIS-C compared to those with KD (40.5% vs. 14.6%, P = 0.009).

OBJECTIVE: To assess the magnitude of active and recovering COVID-19 patients among at-risk communities and to identify the factors associated with positive serology. METHODS: Four hundred and eighty-three close contacts of COVID-19 patients residing in Ho Chi Minh City, Vietnam, during the fourth wave of the COVID-19 epidemic (September and October 2021) were included. Five weeks after exposure to a COVID-19 patient, they underwent a serology test using the BIOSYNEX COVID-19 BSS kit. RESULTS: The median age of participants was 37 years. A total of 34.6% individuals presented at least one clinical symptom between the time of contact with the COVID-19 patient and inclusion in study. A total of 1.7% unvaccinated individuals tested positive for SARS-CoV-2 using real-time PCR, and 9.5% had evidence of recent infection (positive PCR and/or IgM). A further 26.7% unvaccinated individuals presented evidence of a past infection (positive IgG only). Socio-demographic characteristics, vaccination status and clinical symptoms were not associated with a positive IgM test. CONCLUSION: This is the first serosurvey conducted during the fourth wave of the epidemic in Vietnam. It revealed a seropositivity rate higher than in previous studies and confirmed the hyperendemicity of SARS-CoV-2. Testing using rapid serological tests proved to be a reliable, easy-to-use method and enabled a rapid estimation of the burden of COVID-19.

BACKGROUND: Long COVID-19 may affect patients after hospital discharge. AIMS: This study aims to describe the burden of the long-term persistence of clinical symptoms in COVID-19 patients. METHODS: We conducted a systematic review by using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guideline. The PubMed and Google Scholar databases were searched for studies that included information on the prevalence of somatic clinical symptoms lasting at least 4 weeks after the onset of a PCR- or serology-confirmed diagnosis of COVID-19. The prevalence of persisting clinical symptoms was assessed and risk factors were described when investigated. Psychological symptoms and cognitive disorders were not evaluated in this study. RESULTS: Thirty-seven articles met the inclusion criteria. Eighteen studies involved in-patients only with a duration of follow-up of either less than 12 weeks, 12 weeks to 6 months, or more. In these studies, fatigue (16-64%), dyspnea (15-61%), cough (2-59%), arthralgia (8-55%), and thoracic pain (5-62%) were the most frequent persisting symptoms. In nineteen studies conducted in a majority of out-patients, the persistence of these symptoms was lower and 3% to 74% of patients reported prolonged smell and taste disorders. The main risk factors for persisting symptoms were being female, older, having comorbidities and severity at the acute phase of the disease. CONCLUSION: COVID-19 patients should have access to dedicated multidisciplinary healthcare allowing a holistic approach. Effective outpatient care for patients with long-COVID-19 requires coordination across multiple sub-specialties, which can be proposed in specialized post-COVID units.

We investigated respiratory pathogens among ill Hajj pilgrims from Marseille. We also discuss the potential role of point-of-care (POC) rapid molecular diagnostic tools for this purpose. Clinical data were collected using a standardised questionnaire. Influenza A and B viruses, human rhinovirus and human coronaviruses, Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae and Klebsiella pneumoniae were investigated using real-time PCR in respiratory samples obtained during travel, at the onset of symptoms. 207 participants were included. A cough, expectoration, rhinitis and a sore throat were the most frequent respiratory symptoms, followed by loss of voice and dyspnoea. 38.7% and 25.1% of pilgrims reported a fever and influenza-like symptoms, respectively. 59.4% pilgrims received antibiotics. Rhinovirus (40.6%) was the most frequent pathogen, followed by S. aureus (35.8%) and H. influenzae (30.4%). Virus and bacteria co-infections were identified in 28.5% of participants. 25.1% pilgrims who were positive for respiratory bacteria did not receive antibiotic treatment. In the context of the Hajj pilgrimage, it is important to detect infections that can be easily managed with appropriate treatment, and those that can affect prognosis, requiring hospitalisation. POC rapid molecular diagnostic tools could be used for patient management at small Hajj medical missions and to rationalise antibiotic consumption among Hajj pilgrims.

Many studies have shown that re-positive tests for SARS-CoV-2 by RT-PCR in recovered COVID-19 patients are very common. We aim to conduct this review to summarize the clinical and epidemiological characteristics of these patients and discuss the potential explanations for recurrences, the contagiousness of re-detectable positive SARS-CoV-2 virus, and the management of COVID-19 patients after discharge from hospital. The proportion of re-positive tests in discharged COVID-19 patients varied from 2.4 to 69.2% and persisted from 1 to 38 days after discharge, depending on population size, age of patients, and type of specimens. Currently, several causes of re-positive tests for SARS-CoV-2 in recovered COVID-19 patients are suggested, including false-negative, false-positive RT-PCR tests; reactivation; and re-infection with SARS-CoV-2, but the mechanism leading to these re-positive cases is still unclear. The prevention of re-positive testing in discharged patients is a fundamental measure to control the spread of the pandemic. In order to reduce the percentage of false-negative tests prior to discharge, we recommend performing more than two tests, according to the standard sampling and microbiological assay protocol. In addition, specimens should be collected from multiple body parts if possible, to identify SARS-CoV-2 viral RNA before discharge. Further studies should be conducted to develop novel assays that target a crucial region of the RNA genome in order to improve its sensitivity and specificity.

We aimed to compare respiratory pathogen carriage by PCR during three different time periods in 2020 in sheltered homeless people in Marseille, France. The overall prevalence of respiratory pathogen carriage in late March-early April (69.9%) was significantly higher than in late April (42.3%) and mid-July (45.1%). Bacterial carriage significantly decreased between late March-early April and late April. SARS-CoV-2 was detected only in late March-early April samples (20.6%). Measures aiming at mitigating SARS-CoV-2 transmission were effective and also impacted bacterial carriage. Seasonal variations of bacterial carriage between winter and summer in this population were not marked.

The acquisition of enteric pathogens and risk factors for Hajj-associated diarrhea in Hajj pilgrims is poorly documented. Pilgrims from Marseille participating in the Hajj in 2016-2018 underwent successive systematic rectal swabbing before and after their travel. Carriage of the main enteric pathogens was assessed by real-time PCR. Baseline demographics, adherence to individual preventive measures, gastrointestinal symptoms, and treatments were recorded. A total of 376 pilgrims were included. The median age was 62.0 years. During the Hajj, 18.6% presented at least one gastrointestinal symptom, 13.8% had diarrhea, and 36.4% had acquired at least one enteric pathogen. Enteropathogenic Escherichia coli (EPEC) and Enteroaggregative E. coli (EAEC) were the pathogens most frequently acquired by pilgrims (17.6% and 14.4%, respectively). Being female was associated with increased frequency of gastrointestinal symptoms during the pilgrimage (aOR = 2.38, p = 0.004). Enterohemorrhagic Escherichia coli (EHEC) acquisition was associated with a four-fold higher risk of reporting at least one gastrointestinal symptom and diarrhea (aOR = 3.68 and p = 0.01 and aOR = 3.96 and p = 0.01, respectively). Pilgrims who suffered from diarrhea were more likely to wash their hands more often (aOR = 2.07, p = 0.03) and to be either overweight (aOR = 2.71, p = 0.03) or obese (aOR = 2.51, p = 0.05). Enteric bacteria such as E. coli that are frequently associated with traveler's diarrhea due to the consumption of contaminated food and drink were frequently found in pilgrims. Respecting strict measures regarding food and water quality during the Hajj and adherence to preventive measures such as good personal hygiene and environmental management will help reduce the burden of gastrointestinal infections at the event.

The objective of this study is to determine the acquisition of multidrug-resistant (MDR) bacteria and antibiotic resistance-encoding genes by French Hajj pilgrims and associated risk factors. Pilgrims traveling during the 2017 and 2018 Hajj were recruited. All pilgrims underwent two successive systematic nasopharyngeal and rectal swabs, pre- and post-Hajj. Specific culture media were used to screen for MDR bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), carbapenem-resistant bacteria, and extended spectrum beta-lactamase producing Enterobacteriaceae (ESBL-E). qPCR was used to identify antibiotic resistance-encoding genes from cultured isolates. Direct screening of genes encoding for colistin resistance (mcr-1, 2, 3, 4, 5, and 8) from nasopharyngeal and rectal swabs was performed using qPCR, and positive qPCR results were simultaneously tested by sequencing. There were 268 pilgrims included. The percentage of pilgrims acquiring MDR bacteria during the Hajj was 19.4%. A total of 81 strains were isolated (1 carbapenem-resistant Acinetobacter baumannii, 12 MRSA, and 68 ESBL-E). ESBL-E strains were found in rectal samples of 6.0% pilgrims pre-Hajj and of 16.4% pilgrims post-Hajj. Only 0.4% pilgrims were positive for CARB post-Hajj and 1.9% carried nasal MRSA pre- and post-Hajj. In addition, 23 (8.6%) post-Hajj rectal swabs were positive for mcr genes (19 mcr-1 gene and 4 mcr-4 gene). No significant association was found between co-factors and acquisition of MDR bacteria or mcr genes. MDR bacteria and genes are acquired by pilgrims during the Hajj mass gathering. Rationalization of antibiotic consumption and implementation of measures to prevent transmission of bacteria among pilgrims during the event are of paramount importance.

We aimed to assess the prevalence of pathogenic bacteria and resistance genes in rectal samples collected among homeless persons in Marseille, France. In February 2014 we enrolled 114 sheltered homeless adults who completed questionnaires and had rectal samples collected. Eight types of enteric bacteria and 15 antibiotic resistance genes (ARGs) were sought by real-time polymerase chain reaction (qPCR) performed directly on rectal samples. ARG-positive samples were further tested by conventional PCR and sequencing. We evidenced a 17.5% prevalence of gastrointestinal symptoms, a 9.6% prevalence of enteric pathogenic bacteria carriage, including Escherichia coli pathotypes (8.7%) and Tropheryma whipplei (0.9%). Only 2 persons carried blaCTX-M-15 resistance genes (1.8%), while other genes, including carbapenemase-encoding genes and colistin-resistance genes, (mcr-1 to mcr-6, mcr-8) were not detected. Our results suggest that sheltered homeless persons in Marseille do not have a high risk of harbouring gastrointestinal antibiotic resistant bacteria.
RESUMEN
Homeless people are often exposed to unhygienic environments as well as to animals carrying arthropods which both transmit zoonotic infections and human louse-borne pathogens. We attempted to determine the prevalence of antibodies against several vector-borne and zoonotic pathogens among homeless adults living in Marseille. During the 2005-2015 period, we collected sera samples from 821 homeless adults living in shelters. Antibodies against Bartonella quintana, Bartonella henselae, Borrelia recurrentis, Coxiella burnetii, Francisella tularensis (with a cut-off of 1:100), Rickettsia akari, Rickettsia conorii, Rickettsia felis, Rickettsia prowazekii, and Rickettsia typhi (with a cut-off of 1:64) were searched by microimmunofluorescence (MIF). MIF-positive serum samples were confirmed by cross-adsorption to characterise cross-reacting antigens and immunoblotting. Positive sera by Western blot were further tested using qPCR. We evidenced a prevalence of 4.9% seroreactivity to at least one pathogen including phase II C. burnetii (2.1%), B. quintana (1.7%), R. conorii (0.4%), R. prowazekii (0.4%), R. typhi (0.1%), B. recurrentis (0.1%), and F. tularensis (0.1%). No DNA from any pathogens was detected. A comparison with studies conducted prior to the 2000-2003 period showed a decrease in the overall seroprevalence of several vector-borne and zoonotic infections.

Among 467 children under five hospitalized with community-acquired pneumonia, the prevalence of Haemophilus influenzae or Haemophilus haemolyticus was 60.8%, all cases were non-typable H. influenzae (NTHi) or H. haemolyticus. NTHi/H. haemolyticus PCR detection was associated with about twice the risk for severe disease. The results highlight the need for increased awareness and research efforts to investigate the role of NTHi/H. haemolyticus in severe CAP among children.

There have been many studies on the adverse effects of coronavirus disease 2019 (COVID-19) vaccines but the urinary incontinence after COVID-19 vaccination is rare. Here, we report an 8-year-old boy presented to outpatient department, Thai Binh University of Medicine Hospital, Thai Binh, Vietnam with complaints of urinary incontinence for the past 2 weeks, following the first dose of the messenger RNA vaccine. He had no other abnormalities in clinical and laboratory exams. This clinical situation suggested vaccine side effects. No specific treatment was administered upon diagnosis without toilet and bladder training. Subsequent monitoring revealed a gradual reduction in symptoms over 2 months, with complete recovery achieved at the 14th week from the onset of symptoms, without necessitating any medical intervention. This case highlights the need for thorough evaluation and assessment of potential adverse effects following vaccination, including uncommon presentations.
RESUMEN
To investigate potential respiratory pathogens in children with community-acquired pneumonia (CAP) and risk factors for severe disease. This prospective study was conducted among 467 children at the Thai Binh Paediatric Hospital, Vietnam between 1 July 2020 and 30 June 2021. Clinical data and laboratory results were collected. Twenty-four respiratory microorganisms were tested from nasopharyngeal swabs using real-time PCR. Logistical regression was used to estimate a factor's adjusted odd ratios of the severity of disease. Mean age of patients = 15.4 ± 13.3 months, 63.0% were male. Over 97% of patients had a positive PCR result. 87% of patients were positive for multiple (up to eight) microorganisms. Rhinovirus (46%), respiratory syncytial virus (RSV) (24%), enterovirus (17%), and parainfluenza viruses-3 (13%) were the most frequent viruses. H. influenzae (61%), S. pneumoniae (45%) and M. catarrhalis (30%) were the most common bacteria. 128 (27%) cases were classified as severe pneumonia. Presence of smokers at home (aOR 2.11, 95% CI 1.27-3.52, P value = 0.004), CRP level ≥ 50 mg/dL (aOR 6.11, 95% CI 3.86-9.68, P value < 0.0001), RSV (aOR 1.78, 95% CI 1.07-2.96, P value = 0.03) and H. influenzae (aOR 1.66, 95% CI 1.03-2.67, P value = 0.04) PCR detection associated with a higher risk of severe pneumonia; ,. Causative agents of pneumonia in children are complex. Children positive with RSV and H. influenzae need to be closely monitored to prevent severe pneumonia.

BACKGROUND: With an increasing need for COVID-19 vaccination around the globe, we aim to investigate willingness and attitudes of parents regarding COVID-19 vaccines for children in Vietnam. METHOD: A 24-item online survey was conducted among 602 parents and legal guardians of children under 18 years of age. RESULTS: There were 82.6% of parents willing to vaccinate their children. The principal reasons for willingness were: the need for vaccination to control the COVID-19 pandemic and to reduce the risk of SARS-CoV-2 transmission when children return to school. The most common reason for refusing COVID-19 vaccine was the concern about vaccine side effects in children (73.3%), followed by perceived lack of scientific research on COVID-19 vaccines in children (31.4%). The main associated factors with increased willingness of parents towards childhood COVID-19 vaccine were: willingness to allow children to participate in a clinical vaccine trial (aOR = 3.58); possible increase in COVID-19-related mortality (aOR = 3.69); and positive media information regarding COVID-19 vaccine (aOR = 2.04). Noteworthy, higher educational status of parents was associated with decreased willingness for childhood COVID-19 vaccine (aOR = 0.26). CONCLUSION: Understanding reasons of parents to accept childhood COVID-19 vaccines will help future plans in COVID-19 vaccination program. A larger sample size study at a national level is needed to verify the results.

Introduction: The situation of COVID-19 pandemic is becoming more complex. The research institutes should focus on the most important challenge related to this outbreak at the national level. We aim to realize this scoping review to map publications on COVID-19 in Vietnam in order to guide research priorities and policies in the country. Methods: This study was conducted at the Thai Binh University of Medicine and Pharmacy, from May to August 2020, according to the guidance for conducting systematic scoping review. Results: A total of 72 studies met the inclusion criteria. The most frequent publications were original articles (27.8%), followed by letter to editor/correspondence (26.4%). According to the research priorities for COVID-19 set by the WHO, 41.7% studies focused on control and prevention of COVID-19, but none of studies on personal protective equipment or protocol for healthcare workers' safety were conducted. 12.5% studies carried out a thorough investigation into epidemiology of the COVID-19 pandemic in Vietnam. Virology and genomics, natural history of the virus and its transmission in Vietnam were described by 18.1% papers. Only one study was conducted in terms of development for candidate therapeutics. Conclusion: We call for national investigation on treatment against SARS-CoV-2 and protocol for medical staff protection. The government and academic institutions should work in collaboration with international stakeholders, including the WHO, to combat together the COVID-19.

Smell and taste disorders are frequent symptoms during acute COVID-19 and may persist long after the resolution of the initial phase. This study aims to estimate the proportion and risk factors for smell and/or taste disorders at the onset of symptoms and their persistence after more than 6 months of follow-up in COVID-19 patients. We analyzed a prospective cohort of COVID-19 patients admitted to our institute in Marseille, France in early 2020. After being discharged from the hospital, patients with smell and/or taste disorders were contacted for a telephone interview. Logistic regression analysis was performed to determine the risk factors for smell and/or taste disorders. A total of 3,737 patients were included, of whom 1,676 reported smell and/or taste disorders at the onset of symptoms. Taste and/or smell disorders were independently associated with being younger and female, a lower likelihood of suffering from diabetes, cardiovascular diseases and cancer, a longer delay between the onset of symptoms and consultation, and non-severe forms of COVID-19 at admission. Of the 605 patients with smell and/or taste disorders who were followed-up, 154 (25.5%) reported the persistence of symptoms for more than 6 months. At the time of follow-up, being female, having a chronic respiratory disease and using angiotensin-converting enzyme inhibitors (ACEis) were factors independently associated with the persistence of smell and/or taste disorders. In conclusion, the long-term persistence of olfactory and gustative disorders is frequent among COVID-19 patients, notably affecting female patients and patients who suffered from chronic respiratory diseases before infection. The role of ACEis needs to be further evaluated in larger numbers of patients.
RESUMEN
INTRODUCTION: To evaluate the impact of COVID-19 mitigation measures on the total number of consultations for respiratory and gastrointestinal infections among children under 16 years in Thai Binh Pediatric Hospital, Vietnam during the year 2020. METHODS: A retrospective study was carried out to review consecutive consultations occurring in children admitted from January 01, 2016 to December 31, 2020. All medical records were collected from the central numeric database of the hospital. Diagnoses were documented according to the International Classification of Diseases 10 criteria. RESULTS: 436,276 children consulted at the outpatient department during the period of study. A gradual increase in the total number of outpatients was observed from 2016 to 2019, including those consulting for respiratory and gastrointestinal infections. However, the total number of outpatients and the numbers of those consulting for respiratory and gastrointestinal infections dramatically decreased in 2020. A significant decrease of respiratory infections relative proportion was observed in 2020 when compared to 2016-2019 (p < 0.0001). By contrast, the relative proportion of gastrointestinal infections did not significantly vary (p = 0.91). The proportion of outpatients aged under 5 years was significantly lower in 2020 compared to previous years (p < 0.0001). The proportion of male patients was significantly higher in 2020 than from 2016 to 2019 (p = 0.001). CONCLUSION: Public health measures against the COVID-19 pandemic likely decreased the prevalence of other respiratory tract infections. Further studies are needed to validate the effectiveness of each type of measure. Microbiological studies are also recommended, to better understand the effect of preventive measures.

Since the beginning of this outbreak, much evidence stated that the climb in the amount of biomedical waste harmed human health and had adverse effects on the environment. With the increase of cases of COVID-19 all around the globe, the amount of biomedical waste was also constantly rising. Also, many solutions regarding either reducing or recycling biomedical waste. However, the potential global burden of biomedical waste during this pandemic was not yet been analyzed. Herein, we perform a systematic review of literature on these modalities, including mentioning types of biomedical waste, the effect on health, the environment, and methods of handling biomedical waste during this pandemic. A total of 3551 published papers were identified by two databases. In the end, 15 references were selected for this systematic analysis. Most of the included studies focus on research on the impact of medical waste caused by the COVID-19 pandemic on the environment. The total biomedical waste during the COVID-19 pandemic was approximately 16,649.48 tons/day. Most publications agreed that the amount of waste has also increased due to the rapidly rising number of COVID-19 patients. In 15 articles, we identified 2 mentioning the COVID-19 biomedical waste on health. 9 out of 15 gave out the context related to the solution of BMW by COVID-19. More studies, including meta-analyses, are recommended to shed more light on the effects of medical waste on environmental health during the COVID-19 pandemic.
RESUMEN
BACKGROUND: The purpose of the study was to challenge the hypothesis of an introduction of influenza viruses by international travellers and subsequent local circulation in Marseille, France. METHODS: We analysed the epidemiological data of PCR-confirmed cases over an eight-year period and compared the genomic data of local and imported influenza viruses during a six-month period. RESULTS: Between June 2013 and December 2020, 12,434 patients in the Assistance Publique-Hospitaux de Marseille were diagnosed with an influenza virus infection at the laboratory of the Institut Hospitalo-Universitaire Méditerranéee Infection of Marseille. Half of the patients were below the age of 20. Most of the imported cases were diagnosed outside of epidemic periods. Fourteen genomes of the influenza A virus, including six in international travellers returning from Europe or from the Arabian Peninsula and eight from patients who had not travelled were analysed. Sequences of influenza A/H1N1 virus genomes detected in subjects who had travelled to Saudi Arabia were in the same clade and differed from sequences detected later in a traveller returning from Italy, and in non-travellers who were infected in Marseille. This suggests that influenza viruses imported from Saudi Arabia did not subsequently circulate in Marseille. CONCLUSION: Future studies with higher numbers of genomes are needed to confirm this result.
