Chikungunya Virus Spreads Globally, WHO warns of 2004-2005 Epidemic Echoes
The Chikungunya virus, transmitted by infected mosquitoes, has seen a meaningful global spread, with the World Health Organization (WHO) reporting its presence in Madagascar, Somalia, adn Kenya. In 2024, the virus reached India following an outbreak in South Asia, with increased case numbers also noted in Sri Lanka and Bangladesh.Europe has also reported imported cases, with local transmission detected in France and suspected infections in Italy.
Dr. Alvarez of the WHO has drawn parallels between the current situation and the 2004-2005 epidemic, urging immediate international action to prevent a recurrence. Currently, there are no approved vaccines or specific treatments for Chikungunya.
The virus is primarily spread through the bite of infected female mosquitoes, notably Aedes aegypti and Aedes albopictus. Climate change is contributing to the expansion of these mosquito populations, including the “tiger mosquito,” into northern latitudes. These mosquitoes are most active in the early morning and late afternoon.The WHO advises the public to take preventive measures such as using mosquito repellents and eliminating standing water in containers like pots and buckets.
In regions experiencing outbreaks,the WHO notes that low social immunity can lead to up to 75% of the population being affected. Experts emphasize the need for emergency intervention plans to mitigate the impact of the virus.
While Chikungunya is not a mandatory reportable infectious disease in Turkey, it is indeed classified as an arbovirus (a virus transmitted by arthropods, such as mosquitoes).Imported cases have been recorded in individuals with travel history to Asia,Africa,and Indian Ocean islands. Notably, the Aedes mosquito species capable of carrying chikungunya, specifically Aedes albopictus, has been observed in recent years along the Black Sea coast and in the Marmara region of Turkey. This presence raises the potential for future local transmission within the country.
