Background: Seroprevalence studies provide information on the true extent of infection and capture demographic and geographic differences, indicating the level of immunity against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). We sought to provide local evidence of SARS-CoV-2 exposure in s...

Background
The extent of population exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was uncertain in many African countries during the onset of the pandemic.
Methods
We conducted a cross-sectional study and randomly selected and surveyed general population and occupational groups...

Introduction: Longitudinal data and trends about chikungunya virus (CHIKV) are critical for its control, however in Mozambique very few studies were conducted over 5 decades, between 1957 and 2013. In this study, we retrospectively investigated the occurrence, geographical distribution and trend of anti-...

Background: A main criterion to identify malaria vaccine candidates is the proof that acquired immunity against them is associated with protection from disease. The age of the studied individuals, heterogeneous malaria exposure, and assumption of the maintenance of a baseline immune response can confound...

Hantavírus são vírus RNA pertencentes à família Bunyaviridae transmitidos por roedores silvestres de diferentes espécies. Em humanos, os hantavírus estão associados a duas síndromes clínicas: a febre hemorrágica com síndrome renal, descrita na Europa, África e Ásia e a síndrome pulmonar po...
Background: Although Chikungunya virus has rapidly expanded to several countries in sub-Saharan Africa, little attention has been paid to its control and management. Until recently, Chikungunya has been regarded as a benign and self-limiting disease. In this report we describe the first case of severe Ch...

Background: Rubella and congenital rubella syndrome are highly underreported and neglected in most sub-Saharan countries and vaccination has not yet been incorporated into their national immunization schedules. In this study, we investigated the frequency of immunoglobulin M antibodies against rubella an...

Background: The optimum age for measles vaccination varies from country to country and thus a standardized vaccination schedule is controversial. While the increase in measles vaccination coverage has produced significant changes in the epidemiology of infection, vaccination schedules have not been adjus...
