The symptoms of Oropouche are similar to symptoms of dengue, chikungunya, Zika, or malaria.
Oropouche symptoms can often reoccur a few days or even weeks later. Symptoms are reported to be very similar between the initial illness and reoccurrence.
Some people (fewer than 1 in 20) will develop more serious disease. This includes meningitis (inflammation of the membranes that surround the brain and spinal cord), encephalitis (inflammation of the brain), or bleeding.
Rarely, Oropouche may cause Guillain-Barré syndrome (GBS). GBS is a sickness in which a person’s own immune system damages their nerve cells, causing muscle weakness and sometimes, paralysis. These symptoms can last a few weeks or several months. Most people fully recover from GBS, though some people have permanent damage.
Death from Oropouche is rare.
