Oropouche virus cases surge in Brazil as scientists investigate new transmission routes

Oropouche virus cases have surged dramatically in 2024, with over 10,000 reported, primarily in Brazil. This is a significant increase from just 261 cases recorded in Brazil from 2015 to 2022. The Pan American Health Organization has issued an alert for increased monitoring and prevention. A recent study suggests that Oropouche may also spread through sexual contact, raising new concerns. The CDC has recommended that male travelers with symptoms consider using condoms for at least six weeks after symptom onset. However, there are no confirmed cases of sexual transmission yet. Experts believe deforestation and a potential new strain of the virus may be contributing to the rise in cases. The virus has changed enough that people previously immune may now be susceptible. Increased awareness and access to diagnostics are needed to manage the situation.
