Chikungunya Hits Mauritius as the CDC Now Has Four Simultaneous Active Outbreaks Listed - the Widest Multi-Country Chikungunya Warning Since 2014
The CDC has added Mauritius to its list of active chikungunya outbreaks, marking the fourth simultaneous outbreak currently tracked by the agency. This represents the widest geographic spread of the virus since the 2005-2006 Indian Ocean epidemic.

The scale of simultaneous chikungunya outbreaks across two continents and two ocean basins represents the widest geographic spread of concurrent CDC chikungunya travel notices since the catastrophic Indian Ocean outbreaks of 2005 and 2006, which infected an estimated 1.4 million people across R union, Mauritius, Mayotte, and the Comoros islands in a single epidemic wave.
