The Northeast Region presented the highest incidence (243.7 cases/100 thousand population), followed by the Central-West Regions (34.2 cases/100 thousand population) and the North (25.3 cases/100 thousand population).

Officials report 64 chikungunya deaths to date with nearly half reported in Ceará with 46% (30 deaths).

Chikungunya is a viral disease transmitted to humans through the bites of mosquitoes infected with the chikungunya virus.

It was first described during an outbreak in southern Tanzania in 1952 and has now been identified in nearly 40 countries in Asia, Africa, Europe and, most recently, the Americas. Symptoms usually begin 4 to 8 days after a mosquito bite but can appear anywhere from 2 to 12 days.

The most common symptom is an abrupt onset of fever, often accompanied by joint pain. Other symptoms include muscle pain, headache, nausea, fatigue, and rash. Severe joint pain usually lasts a few days but can persist for months or even years. Serious complications are uncommon, but atypical severe cases can cause long-term symptoms and even death, especially in older people.

There is currently no vaccine or specific drug against the virus.
