Arenaviruses are a type of small virus commonly found in rodents. When a person becomes infected with an arenavirus, symptoms usually begin within 10 days.
Prevalence data from sources such as population surveys can be a useful complement to case based surveillance data for hepatitis C. Case-based surveillance has limitations as most diagnosed cases are chronic in nature and detection of cases depends largely on testing practices. Prevalence data can therefore contribute towards a fuller understanding of the epidemiology of hepatitis C.
Marburg virus disease (MVD), formerly known as Marburg haemorrhagic fever, is a severe disease in humans caused by Marburg marburgvirus (MARV). Although MVD is uncommon, MARV has the potential to cause epidemics with significant case fatality rates.
The ECDC HIV Platform Tool is a new end-user application that uses statistical and mathematical methods to calculate adjusted estimates from HIV surveillance data, considering the issues of missing data and reporting delay and employing modelling techniques.
Depending on the level of evidence provided and the methodology used, this advice is typically conveyed through a Guidance, a Systematic review or an Expert opinion.
