RESUMO
BACKGROUND: Varicella is typically mild and self-limiting, but can be associated with complications and even death. The limited data available on varicella in Latin America and the Caribbean (LAC) indicate substantial burden in countries where varicella vaccine is not part of publicly funded childhood national immunization programs. METHODS: A systematic literature review of published studies was complemented by "gray" literature on varicella incidence, complications, mortality, and economic consequences, in the absence and presence of universal varicella vaccination (UVV) in LAC. RESULTS: Seroprevalence data indicate that varicella is usually a disease of childhood in LAC. Varicella incidence rates, while unreliable in the absence of mandatory reporting, show a trend to increased incidence due to greater urbanization and population density. The introduction of UVV in national immunization programs has led to significant reductions in varicella incidence in these areas. CONCLUSIONS: Varicella continues to pose a substantial healthcare burden in LAC. The future introduction of UVV in additional countries is predicted to provide substantial reductions in cases, with important economic benefits. For countries that have already implemented UVV, the challenge is to maintain high rates of coverage and, where relevant, consider inclusion of a second dose to reduce breakthrough cases. Given the significant proportion of the region now implementing UVV, a regional recommendation in order to prevent any potential for age-shifts in varicella infection might be considered.

Invasive pneumococcal disease (IPD) is the leading cause of vaccine preventable deaths in children < 5 years worldwide and it causes a significant disease burden in Latin America and the Caribbean. In order to combat the increasing incidence of IPD in our region, the vast majority of countries have included pneumococcal vaccines as a preventive strategy. The GREEN group (Grupo Regional de Estudio de la Enfermedad Neumococica) has been created to study pneumococcal disease, unify data from the Latin American countries and learn in detail the epidemiology pre and post-pneumococcal vaccination.

Even though there are guidelines for the management of snakebite envenoming (SBE), the use of antibiotics in this pathology remains controversial. The aim of this study is to provide a narrative review of the literature and recommendations based on the best available evidence regarding antibiotic use in SBE. We performed a narrative review of relevant literature regarding SBE and antibiotic use as prophylaxis or treatment. A total of 26 articles were included. There is wide use of antibiotics in SBE; nevertheless, infection was not necessarily documented. The antibiotics used varied according to the study, from beta lactams to lincosamide and nitroimidazoles, and from monotherapy to combined antimicrobials. The most common recommendations were to manage skin and soft tissue infections and avoid infectious complications, but these suggestions are not necessarily based on bacteriological findings. Prophylactic use of antibiotics in SBE is discouraged in most studies. Antibiotic prescription in SBE should be based on the susceptibility of microorganisms isolated from the affected tissue or identified in snakes' oral cavities. Antibiotics should be reserved only for patients with a demonstrated infection, or those at a high risk of developing an infection, i.e., presenting severe local envenoming, local signs of infection, or those with incorrect manipulation of wounds. Prospective studies are needed to correlate microbiological findings at the wound site and the response to antibiotic use.

Respiratory syncytial virus (RSV) is the leading cause of acute lower respiratory infections in children around the world. The post-pandemic era has resulted in a notable increase in reported cases of RSV infections, co-circulation of other respiratory viruses, shifts in epidemiology, altered respiratory season timing, and increased healthcare demand. Low- and middle-income countries are responsible for the highest burden of RSV disease, contributing significantly to health expenses during respiratory seasons and RSV-associated mortality in children. Until recently, supportive measures were the only intervention to treat or prevent RSV-infection, since preventive strategies like palivizumab are limited for high-risk populations. Advances in new available strategies, such as long-acting monoclonal antibodies during the neonatal period and vaccination of pregnant women, are now a reality. As the Regional Expert Group of the Latin American Pediatric Infectious Diseases Society (SLIPE), we sought to evaluate the burden of RSV infection in Latin America and the Caribbean (LAC) region, analyze current strategies to prevent RSV infection in children, and provide recommendations for implementing new strategies for preventing RSV infection in children in LAC region.
RESUMO
Streptococcus pneumoniae (also known as pneumococcus) is part of the natural bacterial flora of the nasal and pharyngeal mucosa, colonizes mainly the nasopharynx, and causes this carriage to precede pneumococcal disease, thus becoming the main source of propagation among people, especially in children. Since 1983, when the first 23-component anti-pneumococcal vaccine was authorized, different conjugated vaccines have been developed according to the circulating serotypes that cause invasive pneumococcal diseases (IPD), reducing the incidence and mortality of these diseases considerably. In November 2021, a group of experts held a virtual meeting to update and analyze the impact that pneumococcal vaccines have generated on the countries' public health, especially during the COVID-19 pandemic. The recommendations that emerged included the need to look for alternatives in serotype-independent vaccines after the introduction of pneumococcal conjugate vaccines (PCV) in the national immunization schedules, as well as to strengthen the surveillance of serotypes, focusing on those not included in the current vaccines. The objective of this report is to communicate the conclusions of the group of experts that in November 2021 analyzed the impact of pneumococcal vaccines on public health in the countries, in order to generate recommendations applicable in Latin America.

Chagas disease, also known as American trypanosomiasis, is caused by Trypanosoma cruzi, a parasite transmitted by hematophagous triatomine insects (subfamily Triatominae) belonging to the Reduviidae family, order Hemiptera. Infection occurs through contact with the feces of the infected vector at the site of its bite or on intact mucosa. [Pediatr Ann. 2023;52(10):e394-e397.].

Since its initial detection in Brazil in February 2020, SARS-CoV-2 and the associated COVID-19 pandemic have continued to devastate Latin America. Specific comorbidities, as well as sociodemographic and lifestyle factors that may be more prevalent in underserved areas, have been identified as risk factors for COVID-19 infection or associated adverse outcomes. Dynamics of infections and deaths in Latin America have varied by country and temporally, as has SARS-CoV-2 variant prevalence; however, more recently, the Delta and subsequent Omicron variants have become ubiquitous. Successful pandemic responses have involved robust infection mitigation measures, testing, and smart deployment of healthcare resourcing. While in some Latin American countries up to 90% of the population is fully vaccinated (i.e., 2 doses) against COVID-19, other countries have failed to reach the World Health Organization's 70% target. Continued focus on comprehensive surveillance, strategies to maximize vaccine availability and uptake, and mitigation of collateral damage on other aspects of public health and social services are critical for managing the COVID-19 pandemic. This review summarizes the COVID-19 experience in Latin America, including epidemiology and vaccination. Key learnings and future considerations for the ongoing pandemic response are also discussed.
RESUMO
BACKGROUND: Pertussis remains as one of the oldest leading vaccine-preventable diseases of childhood, despite many decades of primary vaccine doses' and boosters' implementation. Although the epidemiology is well understood in infants and children, premature babies and low-birth weight infants remain a special group where the disease incidence is unknown, severity of the disease is considerable, and specific vaccination recommendations are scarce. RESEARCH DESIGN AND METHODS: A retrospective review of the available evidence of pertussis vaccination in premature and low birth weight infants was analyzed from January 2000 to December 2022 in six selected countries: Argentina, Mexico, Colombia, Panamá, Costa Rica, and Chile. RESULTS: Chile had reports of adverse effects associated with vaccination of premature infants with the pentavalent vaccine, and their rationale to switching to the hexavalent vaccine. Colombia had reports of the justification for the use of hexavalent vaccine in prematures in the Neonatal Units and Kangaroo Mother Programs throughout the country. Mexico had selected publications of the vaccination status in prematures and low-birth weight infants. CONCLUSION: Despite its importance, increased morbidity, and highest risk of complications in premature babies, there is a paucity of information of vaccine recommendations and coverage rates among selected Latin American infants.

While the first 1,000 days of life are a critical period in child's development, limited information on the main determinants affecting this period in the Latin America and the Caribbean (LAC) region is available. Therefore, the Latin American Pediatric Infectious Diseases Society (SLIPE) held an ad hoc workshop in May 2022 with an expert panel designed to analyze the main factors impacting the development of childhood in the region during this period and the main causes of maternal infant morbimortality. The aim was to identify priorities, generate recommendations, and advise practical actions to improve this situation. Considerations were made about the challenges involved in bridging the gap that separates the region from more developed countries regarding an optimal early childhood and maternal care. Extensive discussion was conducted to reach consensus recommendations on general strategies intended to reduce maternal and infant mortality associated with infections and immune-preventable diseases during the first 1,000 days of life in LAC.
RESUMO
INTRODUCTION: The WHO 2030 Immunization Agenda (IA-2030) harmonizes immunization activity plans at community, national, regional and global levels. Additionally, medical societies play an important role. The Latin American Group of Experts on Infant Immunization, established in 2018, advises on the harmonization, update, and optimization of infant vaccination programs in Latin America and the Caribbean (LAC). In September 2021, 41 such experts from 13 LAC countries met to develop recommendations for increasing regional vaccination coverage to avoid the reemergence of vaccine-preventable diseases and/or the occurrence of outbreaks. AREAS COVERED: The following items were evaluated: (i) immunization challenges before and during the COVID-19 pandemic; (ii) the status of current immunization programs, particularly infant pertussis and polio vaccination; (iii) possible solutions for overcoming vaccination challenges and achieving regional vaccination coverage targets. EXPERT OPINION/COMMENTARY: Medical societies provide valuable recommendations to guide and update vaccination schedules. In the LAC region, possible strategies to achieve target vaccination rates include the use of combination vaccines, strengthening surveillance systems, improving school attendance, advancing vaccine education and confidence, striving for vaccination equity, widening operational capacity, creating strategic alliances, and strengthening the role of medical groups. It is hoped that these recommendations will be implemented in the LAC region.

Costa Rica introduced the measles-mumps-rubella (MMR) vaccine in 1986. The Ministry of Health adopted the goal of eliminating endemic measles in 1991 by achieving and maintaining high vaccine coverage through routine delivery, mass campaigns and outreach activities, and the strengthening of expanded program on immunization (EPI) surveillance. Measles and rubella immunization strategies shifted susceptibility to older age groups, leading to the introduction of MMR2 in 1992, administered at age 7 years. In 2000, the goal of accelerated rubella control and congenital rubella syndrome prevention was established, and a nationwide vaccination campaign targeting men and women aged 15-39 was implemented to immunize the population of reproductive age. The last endemic case of measles was confirmed in 1999, and at the end of 2001 Costa Rica reported the last endemic cases of rubella and congenital rubella syndrome. Imported cases of measles and rubella were detected in 2003 and 2005, with no secondary cases detected. In 2008, Costa Rica established a National Committee of Experts, supported by technical teams, to collect the evidence required to verify the interruption of endemic transmission of the measles and rubella viruses. The evidence includes information on trends and epidemiologic analysis, molecular epidemiology, population immunity, the quality of surveillance, and the sustainability of the EPI program.

Costa Rica is an upper middle-income country in Central America with a vigorous public health system. We have studied the number of cases, hospitalizations, and deaths due to pertussis from 1961 to 2018, in relation to vaccine coverage. Following the introduction of the fourth and fifth doses of DTP (booster doses) in 1973 there was a marked reduction of reported pertussis. In 2002 pertussis surveillance and laboratory diagnosis were improved. In 2007, Tdap post-partum immunization was introduced and then switched to intrapartum Tdap immunization in 2011. Of these two strategies post-partum vaccination seemed to have a greater effect in decreasing hospitalizations and deaths, nevertheless, since 2011 there has been only 4 infant deaths due to pertussis.

OBJECTIVE: We aimed to evaluate the clinical and epidemiological behavior of influenza type A versus type B and analyze if there was any correlation or differences between the characteristics of both groups. METHODS: An observational, retrospective, descriptive, and population-based study based of children who were hospitalized at the only national pediatric hospital of Costa Rica from January 1, 2010 to December 31, 2018 and had a confirmed influenza virus infection. RESULTS: 336 patients were analyzed. Mean age was 35,6 ± 36,7 months (3,0 ± 3,1 years). The only significant variables at 25% in relation to influenza type A or B virus were: sex, month of diagnosis, fever, vomiting, cough, use of antibiotics and admission to the PICU. The hospitalization rate at our hospital increased between the months of October to December, with a higher percentage of cases in November and December, which reveals that the "real peak" in our population begins between 3 to 4 months after the end of the vaccination campaign. Patients with influenza A virus had a 2.5 times greater risk of being admitted to the PICU. Mortality rate was 0.6% and 0% among influenza A and B children, respectively. CONCLUSIONS: Variables in which a causality was found with type A or B virus were: admission to the PICU, month of diagnosis, and cough. However, influenza B clinical behavior continues to be unpredictable.

Bacillus Calmette-Guérin (BCG) local scar inflammatory reactions have been mostly associated with Kawasaki disease in children and less commonly with other viral infections (i.e., measles). BCG scar inflammation associated with or following vaccine administration has only been reported with the influenza vaccine. We describe the first reports in the literature of local BCG inflammation following two different available messenger ribonucleic acid (mRNA) anti-severe acute respiratory syndrome coronavirus 2 (anti-SARS-CoV-2) vaccines (mRNA-1273, and BNT162b2) in two young healthy physicians, one from Costa Rica, and another from the United States of America, with normal cell blood counts, flow cytometries, and negative for human immunodeficiency virus (HIV). In both cases, BCG scar inflammation appeared after 24 hours of vaccination of the second dose, without signs of reaction on the injection site, and resolved within four days. Dermoscopic findings in one case showed arborizing and comma-shaped vessels. Pharmacovigilance surveillance of BCG scar reactions following coronavirus disease 2019 (COVID-19) vaccines should be considered particularly in countries where BCG is part of their national immunization programs.
RESUMO
Background Understanding antibiotic profiles and their resistance patterns can improve hospital quality care and optimize clinical outcomes. This paper characterizes the use of meropenem in the National Children's Hospital of Caja Costarricense del Seguro Social (CCSS) in Costa Rica, and its role in antibiotic stewardship. Methods This is a retrospective observational study from hospitalized patients under 13 years of age that received meropenem as part of their treatment. Patients were identified through medical and pharmacy records. Data was summarized using frequencies and percentages for categorical variables, means and standard deviations for normally distributed continuous variables, and medians with interquartile ranges (IQR) for non-normally distributed continuous variables. Results A total of 181 of the 309 selected patients met inclusion criteria. Median age was 21 months (IQR: 4.0-79.0). Mean length of stay was 31 days (16.0-58.0). The most frequent diagnosis was septic shock (29%). 87% of patients received at least one antibiotic prior to receiving meropenem; 71% of patients received a second antibiotic simultaneously with meropenem. In 113 (62%) cases, meropenem was prescribed as empirical therapy. The most frequent isolate was extended-spectrum ß-lactamase Escherichia coli (24%). 74% of patients who received meropenem as targeted therapy had a favorable outcome. Conclusions Meropenem can be used as monotherapy for complicated, multi-drug resistant, gram negative, bacterial infections, due to its susceptibility profile, convenient dosing schedule, and minimum adverse effects. However, it should be restricted to cases where no other drug is available in order to safeguard its value.
RESUMO
Since 2020, the COVID-19 pandemic has had a significant impact on morbidity and mortality around the world. As one of the most successful and cost-effective health interventions for preventing infectious diseases, immunization against SARS-CoV-2, is at the moment the most effective strategy for controlling the current pandemic. Despite the high vaccine acceptance rates that countries such as Costa Rica have shown in the past, the public acceptance of the COVID-19 vaccine is still uncertain. The purpose of this study was to examine adults' willingness to get a novel COVID-19 vaccine and its potential predictors in Costa Rica. We conducted a cross-sectional study comprising a sample of 4717 adult participants living in Costa Rica who participated in a voluntary electronic survey regarding their intent to get a future COVID-19 vaccine. Results suggest that a high percentage (86.1%) of Costa Ricans aged 18 or more would be willing to be vaccinated once a safe and effective vaccine is approved and distributed in the country. Some relevant significant predictors of willingness to get a COVID-19 vaccine in Costa Rica were higher income, being male, work in the health care sector, and having a relative or a close acquaintance diagnosed with COVID-19. Our findings suggest that it is essential to concentrate efforts on the immediate development of culturally appropriate communication, dissemination, and implementation strategies to maximize immunization against SARS-CoV-2 in Costa Rica.
RESUMO
Introduction: The Latin American Society of Pediatric Infectology (SLIPE for its acronym in Spanish) is working hard to contribute with strategic actions to prevent the recurrence of Vaccine-Preventable Diseases and to prevent the reduction of vaccine coverage in the region of the Americas.Areas covered: On Friday, September 25th, a Latin American forum of experts on immunization services during the COVID-19 pandemic was held through Webex platform. Issues such as: the imminent risk of occurrence and outbreaks of vaccine-preventable diseases, the importance of epidemiological surveillance and the vaccination campaign challenges, in the context of a pandemic were discussed.Expert opinion: Vaccination campaigns should no longer be postponed or delayed; instead, they must be reactivated; governments, scientific societies, and physicians must promote vaccination programs to avoid outbreaks of vaccine-preventable diseases. On the eve of a SARS-CoV-2 vaccine, it is necessary to insist on the availability of sufficient doses to avoid dose shortages in disadvantaged areas of the region.

Pertussis remains endemic across the world, with an estimated 279,000 deaths in 2002, the majority in infants under 1 year of age. Worldwide epidemiologic data indicates increasing infection rates in older children and adults, which act as a source of infection to young infants. The Global Pertussis Initiative (GPI) is an expert scientific forum, which has published consensus recommendations for the monitoring, prevention, and treatment of the disease. This paper reports the proceedings of a regional meeting, held in Costa Rica in December 2008. The meeting gathered information on regional epidemiological, diagnostic capabilities and the ability to introduce GPI recommended vaccine strategies in Latin America. The capacity of Latin American countries to conduct vaccination programs is high and there is considerable government support. Whole-cell pertussis vaccines are used across Latin America, which appear to be quite effective. A 4-dose schedule is typically used (2, 4, 6, and 18 months), and a booster given at 4 to 6 years of age, with coverage often above 90%, but with regions of low coverage due to political and geographical difficulties. Adequate surveillance is lacking in many countries, giving insufficient data to guide vaccination policy. Improvements are being made, with countries such as Costa Rica, Panama, and Argentina introducing polymerase chain reaction (PCR) diagnosis. Those countries that do not currently use a preschool booster should launch one. Implementing vaccination programs in adolescents and/or adults to reduce exposure to infants would be beneficial and possible in most countries, given their current infrastructure.

Actinomycosis is a relatively uncommon bacterial disease of childhood, especially when presenting as deep-seated infections. Only 10% of affected patients are younger than 18 years of age. In children, cervical actinomycosis is the most common form of clinical presentation, and among the abdominopelvic form, renal abscesses are rare. We describe an uncommon and severe case of a five-year-old Costa Rican girl with thoracic and renal actinomycosis who required a complete nephrectomy.
