Mauritius: Chikungunya outbreak update
During the week ending June 28, the Mauritius Ministry of Health (MOH) reported 90 additional confirmed chikungunya cases (Mauritius- 88 and Rodrigues island- 2), and no deaths.
Since the beginning of 2025, 1,440 total confirmed chikungunya cases (1,395 local) and no deaths.
Fifty-five percent of the cases were in males, while one quarter of cases were reported in people aged 20-39.
The last chikungunya outbreak in Mauritius occurred in 2009 when more than 12,000 cases were reported.
Chikungunya disease is caused by the chikungunya virus and is spread to humans through mosquito bites. Outbreaks have occurred in countries in Africa, Americas, Asia, Europe, the Caribbean, and Indian and Pacific Oceans.
Most people infected with chikungunya virus develop some symptoms. Symptoms of chikungunya usually begin 3–7 days after a bite by an infected mosquito. The most common symptoms are fever and joint pain. Other symptoms may include headache, muscle pain, joint swelling, or rash. Most people get better within a week; however, some can have severe joint pain for months to years following acute illness.
People at risk for more severe disease include newborns infected around the time of birth, older adults (65 years or older), and people with medical conditions such as diabetes or heart disease. Death from chikungunya is rare.
There is no specific treatment for chikungunya..
