Chikungunya: risks and solutions

Chikungunya or CHIK is a tropical infectious disease caused by a virus of the arbovirus family. Chikungunya means "walking in half" in Swahili. Malagasy call this disease the disease of the curved man.

Arboviruses are very numerous and give arboviroses (viral diseases) characterized by fever associated with joint pain: the best known are the dengue virus, O'Nyong-Nyong (ONN) and CHIK.

Chikungunya appeared in the 1950s in Tanzania, the virus was also isolated in Southeast Asia and India; it is epidemic in the inter-tropical regions of Africa and Asia.

Indonesia experienced 24 epidemics between 2001 and 2003, Senegal suffered a major epidemic between 1996 and 1997, the Democratic Republic of Congo between 1999 and 2000. The islands of the Indian Ocean were also affected: the Comoros, Mayotte, Mauritius, Reunion, Madagascar.

In Réunion, since the beginning of 2006, the CHIK virus seems more virulent, the number of patients affected is important, the signs of the disease are more severe. Measures have been taken to severely limit the spread of the disease, particularly in Reunion and Mauritius.

As for the Chikungunya epidemic that appeared in December 2013 in the West Indies and Guyana, which has already affected 147, 000 people, it is currently stabilizing.
