Tourists Risk Marburg Virus Exposure in Uganda
5 Mar
Summary
- Marburg virus found in fruit bats within Python Cave, Uganda.
- Hundreds visited the cave without protective gear, including school groups.
- Predators interact with bats, potentially increasing zoonotic spillover risk.
Marburg virus, a pathogen capable of causing outbreaks with a high fatality rate, has been identified in fruit bats inhabiting Python Cave in Uganda's Maramagambo Forest. This cave, located within Queen Elizabeth National Park, is a significant reservoir for the virus, with an estimated seven percent of its 56,000 Egyptian fruit bats carrying the disease.
Despite the known risks, including a past tourist fatality from Marburg after visiting the cave, hundreds of people, including school groups and tourists, have been recorded entering the vicinity without wearing protective equipment. Researchers have documented over 14 species of predators, such as leopards and monkeys, interacting with the bats within the cave, a phenomenon termed a "spillover crucible."
Scientists emphasize that while these interactions demonstrate contact, they do not confirm viral spillover between species. However, the close proximity and direct contact observed, especially with primates, raise concerns about the potential for the virus to adapt and jump to humans. Marburg virus spreads through direct contact with bodily fluids of infected individuals or contaminated surfaces.
