Philippines health officials report 1,409 chikungunya cases through August 12 this year, a 213 percent increase compared to the same time in 2022 when 450 cases were reported.
The Cordillera Administrative Region (CAR), in the northern Philippines, has seen the most cases with 372 year to date, a 18,500 percent increase from last year.
According to the WHO, 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.
