Snakebite envenoming is a serious public health problem in Central America, where approximately 5,500 cases occur every year. Panama has the highest incidence and El Salvador the lowest. The majority, and most severe, cases are inflicted by the pit viper Bothrops asper (family Viperidae), locally kn...own as ‘terciopelo’, ‘barba amarilla’ or ‘equis’. About 1% of the bites are caused by coral snakes of the genus Micrurus (family Elapidae). Despite significant and successful efforts in Central America regarding snakebite envenomings in the areas of research, antivenom manufacture and quality control, training of health professionals in the diagnosis and clinical management of bites, and prevention of snakebites, much remains to be done in order to further reduce the impact of this medical condition. This essay presents seven challenges for improving the confrontation of snakebite envenoming in Central America. Overcoming these challenges demands a coordinated partnership of highly diverse stakeholders though inter-sectorial and inter-programmatic interventions.

HIV testing programmes need to ensure that all clients who test for HIV are provided with correct diagnoses. The accuracy of HIV testing is critical to prevent misdiagnosis, as the consequences of giving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and pu...blic health.
With the evolution of global HIV epidemiology, HIV testing approaches must also evolve to maintain accuracy and efficiency in population-level diagnosis. Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used. As a result of changing epidemiology and declining HIV positivity in testing, WHO recommends all countries use a standard three-test strategy to ensure a PPV of at least 99%, minimizing false-positive misdiagnosis. The WHO-recommended HIV testing strategy, along with quality assurance measures such as retesting to verify a positive diagnosis prior to initiation of HIV treatment, is cost-effective as it prevents misdiagnosis and unnecessary initiation of costly lifelong treatment.
This implementation guide provides practical advice on switching to a three-test strategy and instituting other measures that can help national HIV programmes deliver high-quality, accurate HIV testing services and ensure that misdiagnosis is minimized.

As of 12 December 2022, over 645 million people worldwide have been diagnosed with COVID-19, with over 6.6 million deaths (4).
The Omicron variant, which emerged in late November 2021, and its subvariants, are now the dominant circulating viruses, contributing to the ongoing surge in several countr...ies (4). Vaccination has substantially reduced case numbers and hospitalizations in many countries,but limitations in global access to vaccines mean that many populations, including those in low- and middle-income countries, remain vulnerable. Even in vaccinated individuals, uncertainties remain about duration of protection and efficacy, and the degree of crossprotection with new variants.
There remains a need for more effective treatment and management for those affected by COVID-19. The pandemic – and the
explosion of both research and misinformation – has highlighted the need for trustworthy, accessible and regularly updated living
guidelines to place emerging findings into context and provide clear recommendations for clinical practice

2nd edition. Children with TB comprise about 10-12% of the total TB cases diagnosed in the country. This burden is likely to be higher given the challenges in diagnosing TB in children. The symptoms of TB in children mimic those of other childhood diseases. Children do not readily expectorate and th...ey have pauci-bacillary TB hence some will be missed using bacteriological tests. The government has however introduced GeneXpert molecular testing that is more sensitive than microscopy in detecting TB. Health care workers therefore need a reference guide to obtaining sputum from children for testing. Treatment of TB in children has been reviewed and now includes Ethambutol. There are now improved paediatric friendly TB medicines for treatment of TB in children and health care workers need a reference guide to enable them accurately dispense the TB medicine to children. Malnutrition is a common predisposing factor for TB in children. On the other hand, TB predisposes children to malnutrition or worsens an existing state of malnutrition. Nutrition care and support forms an integral part of treatment for a child with TB disease.

Real-time polymerase chain reaction (PCR) is a sensitive and specific method for diagnosing schistoso-
miasis. However, this method should be performed in a laboratory, usually located distant from the sample collection
site. Therefore, it is important to have fas...t sampling preservation methods, which allow simple transport prior to DNA
extraction and amplification. The aim of this study was to verify if blood samples applied to filter paper are suitable for
analysis of Schistosoma mansoni DNA by real-time PCR.
