Officials from the World Health Organization are warning the public about a potential resurgence of the chikungunya virus, which is reportedly spreading beyond its usual areas, as reported by Reuters.
What’s happening?
Chikungunya was first identified in Tanzania back in 1952 and has since spread throughout Africa and Asia, especially in areas around the Indian Ocean. It’s transmitted mainly by mosquitoes like the Aedes aegypti and Aedes albopictus. People bitten by these mosquitoes typically experience fever and considerable joint pain.
Currently, around 5.6 billion individuals across 119 countries are believed to be at risk as the virus makes its way to Europe and other regions. WHO officials express concern that this situation mirrors a previous epidemic from 2004 to 2005 that affected nearly half a million people.
“We are seeing history repeating itself,” noted Diana Rojas Alvarez, a medical officer at the WHO, according to Reuters.
Why are mosquito-borne illnesses important?
The WHO indicates that mosquitoes are the most common carriers of disease, with illnesses like chikungunya, malaria, and West Nile causing approximately 800,000 deaths annually worldwide.
Infections are particularly prevalent in warm, humid environments where mosquitoes thrive. As global temperatures rise, the habitats conducive to these insects are expanding.
What’s being done about mosquito-borne illnesses?
As of now, there are no medications specifically for treating chikungunya, although two types of vaccines can be found in the United States, and acetaminophen or paracetamol may help relieve symptoms, per the CDC. Prevention remains crucial regarding mosquito-borne diseases.
Controlling mosquito populations and preventing their breeding can effectively reduce the incidence of these illnesses. For example, in California, officials are working to sterilize male mosquitoes, while scientists in Burkina Faso are developing a fungus intended to kill off mosquitoes during mating.
