What type of illness does chikungunya virus cause?
Chikungunya virus infection can cause a debilitating illness, most often characterized by fever, headache, fatigue, nausea, vomiting, muscle pain, rash, and joint pain. “Silent” chikungunya virus infections (infections without illness) do occur; but how commonly this happens is not yet known. Chikungunya virus infection (whether clinically apparent or silent) is thought to confer life-long immunity. Acute chikungunya fever typically lasts a few days to a couple of weeks, but as with dengue, West Nile fever, o’nyong-nyong fever and other arboviral fevers, some patients have prolonged fatigue lasting several weeks. Additionally, some patients have reported incapacitating joint pain, or arthritis which may last for weeks or months. What is the incubation period for chikungunya fever? The incubation period (time from infection to illness) can be 2-12 days, but is usually 3-7 days. Can pregnant women become infected with chikungunya virus and pass the infection to their child?
