Spurt in chikungunya cases highlights need to check vector population
As on August 4, a total of 105 confirmed and 62 probable chikungunya cases have been reported from various parts of the State, primarily Thiruvananthapuram. Intense monsoon rainfall interspersed with spells of hot weather has led to an abundance in Aedes mosquitoes
An uptick in chikungunya cases is raising concerns about the need to control the population of disease-carrying mosquitoes. Intense monsoon rains combined with hot weather have created an ideal environment for the proliferation of Aedes mosquitoes, which transmit both dengue and chikungunya viruses. Following major outbreaks in 2006-07 and 2019-20, the state is once again experiencing a surge in chikungunya cases this year, with over 100 confirmed and 60 probable cases reported by August 4, primarily in Thiruvananthapuram.
Public health experts warn that the actual number of cases may be significantly higher, as many patients are not tested and do not seek medical attention. The World Health Organization (WHO) issued a global alert in July 2025, expressing concern over the resurgence of chikungunya and the risk of a repeat of the 2004-05 epidemic, which originated in the French Reunion islands.
WHO has since modified the threat perception to "moderate" but has emphasized the potential for large localized surges to overwhelm healthcare systems, particularly among vulnerable groups such as pregnant women, newborns, and individuals with preexisting conditions like diabetes or hypertension. Experts stress the importance of active surveillance to accurately track case numbers and highlight the long-term joint inflammation and disability that can result from chikungunya infection, which can cause severe morbidity without causing mortality.
The 2007 epidemic left hundreds of thousands in Kerala with debilitating long-term health issues, highlighting the economic and social consequences of such outbreaks.
