Oropouche virus in Peru

07 Jun 2016

The Ministry of Health of Peru reported 57 cases of Oropouche fever on 2 May 2016; most of these cases are from the northern part of the Cusco Region, which is located in the Amazon rainforest. The majority of cases were detected in January (79%), only 7% were detected in February and 14% detected in March. To date, there have been no fatalities and all cases have recovered following symptomatic treatment.

In response to this outbreak Peruvian health authorities are strengthening vector control (removal and modification of midge breeding sites).

Oropouche fever is caused by the Oropouche virus. Symptoms include the sudden onset of high fever, myalgia, headache, joint pain and vomiting. In some patients it may cause clinical symptoms of aseptic meningitis.

Advice for Travellers

In humans, Oropouche virus is primarily transmitted through the midge bite, bite avoidance should therefore be practiced. Bite avoidance measures include: covering up with clothing, the use of insect repellent and bed nets impregnated with insecticide.
