In a follow-up on the chikungunya situation in Thailand, health officials now report 4,040 cases in 58 provinces through July 6.
Provinces with the highest incidence include Chanthaburi, Uthai Thani, Lamphun, Rayong and Loei.
Chikungunya virus (CHIKV) is transmitted by the bite of Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus. In humans bitten by an infected mosquito, the disease symptoms usually appear after an incubation period of three to seven days (range 1- 12 days).
CHIKV can cause acute, sub-acute, and chronic disease.
In acute disease, symptoms develop abruptly and include high fever, headache, myalgia and arthralgia (predominantly in limbs and large joints). The appearance of a maculopapular rash is also frequent. Severe forms of the disease are rare. Symptoms usually resolve in 7-10 days, although arthralgia and joint stiffness may persist intermittently for several months.
The disease shares some clinical signs with dengue and Zika, and can be misdiagnosed in areas where they are common. As there is no cure, treatment is focused on relieving the symptoms.
In addition, the Bureau of Epidemiology is now reporting 25,708 total dengue fever cases in all 77 provinces. Of this total, 7645 are dengue hemorrhagic fever (DHF) cases and 212 are dengue shock syndrome (DSS) cases,
15 deaths have been reported.
Provinces with the highest incidence include Chaiyaphum, Rayong, Khon Kaen, Mae Hong Son and Nakhon Ratchasima.
