There is a risk of death 3 months after getting chikungunya, ‘The Lancet Infectious Diseases’ told the risks of yellow fever infection

National Content Cell: People infected with Chikungunya virus remain at risk of death for three months after infection. This has been said in a report published in the journal ‘The Lancet Infectious Diseases’.

• Chikungunya was first identified in southern Tanzania in 1952.

• After 11 years, in 1963, cases of Chikungunya were reported for the first time in India.

Researchers said that last year, about five lakh cases of chikungunya were reported worldwide and more than 400 people lost their lives due to this infection. These figures have come to light when most of the cases of this infection remain unreported. According to researchers, most patients recover completely from this infection, but still Chikungunya disease can prove fatal. Therefore, it is important to consider the continuing threat even after high levels of infection have ended.

Research results show that people infected with this virus remain at risk of complications even after the period of acute infection ends. The duration of acute infection is usually 14 days after symptoms appear. In the first week, an infected person has up to eight times the risk of death compared to another person. An infected person has double the risk of death from complications three months after infection. According to researchers, there is no specific treatment available to prevent chikungunya or treat this disease after infection.

People above 18 years of age are at greater risk, vaccine approved

People above 18 years of age are at greater risk of chikungunya. In view of this, in November last year, the US Food and Drug Administration (FDA) approved the world’s first vaccine. This vaccine named ‘Ixchik’ has been approved for people above 18 years of age. It is given as a single dose through injection into the muscle. It contains a live, weakened version of the chikungunya virus, potentially causing similar symptoms of the disease in vaccine recipients. Individuals who are at higher risk of becoming infected with the virus and who are 18 years of age or older can receive the vaccine. The FDA has said that it will work to prevent a disease that cannot be completely treated yet.

Urbanization and human activities responsible for the threat

Researchers said that due to climate change, urbanization and rapidly increasing human activities, there is a high risk of Aedes-borne diseases increasing and spreading to other areas. In this context, Chikungunya disease is appearing as a growing threat to public health.

what is chikungunya

Chikungunya is a viral disease, which spreads to humans through the bite of infected female mosquitoes. Usually this includes Aedes aegypti and Aedes albopictus mosquitoes. Both these species can also transmit other mosquito-borne viruses including dengue. They bite in daylight. However, this activity may peak in the morning and afternoon. It is also commonly called yellow fever.

Origin from Kimakonde language

The word ‘chikungunya’ originates from the Kimakonde language (spoken by the Makonde people, an ethnic group of Tanzania and Mozambique), which translates to ‘to become disfigured’. This reflects the slouched posture of individuals experiencing severe joint pain.

symptoms

Chikungunya causes fever and severe joint pain, which is often debilitating and of varying duration. The symptoms of dengue and Zika are similar to those of chikungunya, which can lead to misdiagnosis of chikungunya.

prevention and treatment

There is currently no cure for chikungunya, symptomatic relief is the primary solution. Treatment includes analgesics, antipyretics, rest and adequate fluid intake. Prevention includes using mosquito nets and preventing water logging to prevent mosquito breeding.
