What is chikungunya disease, how to prevent from chikungunya
Chikungunya is a mosquito-borne viral disease that causes fever and severe joint pain. It is caused by a ribonucleic acid (RNA) virus that belongs to the alphavirus genus of the family Togaviridae.
The name “chikungunya” derives from a word in the Kimakonde language of southern Tanzania, meaning “that which bends up” and describes the stooped appearance of infected people with severe joint pain (arthralgia).
chikungunya virus infection
Chikungunya virus (CHIKV) is transmitted to humans by the bites of infected female mosquitoes, most commonly Aedes aegypti and Aedes albopictus mosquitoes. These two species can also transmit other viruses, including dengue and Zika viruses.
They bite primarily during daylight hours, and there may be peaks of activity in the early morning and late afternoon.
History and Origin of Chikungunya
Chikungunya was first identified during an outbreak in southern Tanzania in 1952. Since then, the virus has spread to many countries in Africa, Asia, Europe, and the Americas. Over the last few decades, urbanization and increased travel have contributed to its global spread.
Chikungunya has now been reported in >110 countries in Asia, Africa, the Americas and Europe.
what is chikungunya Symptoms
Symptoms of chikungunya appear between 4 and 8 days (range 2–12 days) after the patient has been bitten by the infected mosquito. Chikungunya is rarely fatal. Most symptoms are generally self-limiting and last for 2–3 days. The disease is characterized by an abrupt onset of fever, which is frequently accompanied by joint pain.
Other common signs and symptoms include muscle pain, headache, nausea, fatigue and rash. The joint pain is often debilitating and usually lasts for a few days but may be prolonged, lasting for weeks, months or even years.
