Epidemiology of chikungunya in India—a short review.

Abstract

ABSTRACT   Chikungunya is a viral infection triggered by CHIKV, which belongs to the alphavirus family and is transferred by the bites of infected Aedes mosquitoes both  A. aegypti and A.albopictus to humans. During the post-storm season, the transmission of the infection increases due to the increase in the population of the mosquito. It demonstrates the same pathogenicity as dengue fever. The symptoms initiate within 4 and 7 days of the patient being chomped by the CHIKV- infected vector. Symptoms include high fever (40°C/104°F), chills, cerebral pain, regurgitation, joint agony (lower back, lower leg, ankles, wrists, or phalanges), muscle torment, nausea, fatigue rash, and arthralgia. It is thought that the important source, or stockpile, of mosquito Chikungunya infection, is Homo sapiens. In researching the data sets from 1948 to 2017 (69 years), we noted that more cases were recorded for Chikungunya especially from the eastern and western parts of India during the period 1982-2017 in contrast to 1948 -1981 when there was an unremitting increase in the standard temperature. Chikungunya instances began to spike during 1982-2016 when ordinary temperatures had risen to just 29°C. At the temperature (27- 34°C), A. aegypti and A. albopictus, the basic bearers, indicated a greater gnawing frequency, and the most amazing pervasive rodent of chikungunya instances (83.6 per million population) was accounted for in 2006-2017. This review was intended to determine the chikungunya’s status in India and to comprehend the risk factors associated with the growing incidence of chikungunya.
