The World Health Organization said that chikungunya may cause fever, severe joint pain, joint swelling, muscle pain, headache, nausea, fatigue and rash.

Amid the increase of chikungunya cases in 2023, the DOH said that based on its most recent data, cases of the vector-borne disease are actually going down.
“While there have been a total of 2,928 Chikungunya cases reported, in the recent 3-4 weeks (November 19 to December 2, 2023) only 57 cases were reported, a 51 percent decrease from the 116 cases reported two weeks prior,” the health department said.
The DOH explained that chikungunya cases tend to increase during the rainy season, from June to September, and while 2023 saw an uptick in cases during those months, cases have since been decreasing.
The DOH said that symptoms of chikungunya may include fever, joint pain, joint swelling, rashes, headache, body aches, nausea, and fatigue.
These symptoms appear three to seven days after the patient is bitten by a mosquito carrying the virus.
Meanwhile, cases of dengue fever – also transmitted by mosquitoes – plummeted nationwide by 23 percent this year, with 195,603 cases logged so far, from 252,700 in 2022.
