Tuesday, February 2, 2010
chikungunya virus (RNA virus)
Chikungnya involved an African virus (RNA virus) and an Asian mosquito, which reflecting the globalization of vectorborne diseases. The Aisan mosquito involved, is none other than Aedes mosquito.
Chikungnya's symptoms are similar to dengue fever: fever, joints pain and the tendency of bleeding.
The incubation period of Chikungunya disease is from 2 to 4 days. [4]
Then, patients will have fever up to 39 ℃ (102.2 ℉), red spots or rashes of the trunk and occasionally the limbs, and arthralgia (joint pain) or arthritis (inflammation of the joints) affecting multiple joints. [5, 6] - Acute Phase
Other nonspecific symptoms can include headache, conjunctival injection, and slight photophobia.
Typically, the fever lasts for 2 days and then ends abruptly (dengue fever has longer period of fever).
Patients have complained of joint pains for much longer time periods depending on their age. [5, 6] - Chronic phase (not all patients will have it)
The management of the disease includes rest, fluids and medications to relieve symptoms of fever and pain, such as ibuprofen, naproxen and paracetamol. Aspirin should be avoided (may cause refractory arthritis).
