Chikungunya virus exposure may vary from country to country in South America

In Brazil, slightly more than 64,000 cases of chikungunya have been registered in 1,358 municipalities. In contrast, in Caldas Department in Colombia, only 29 cases have been recorded in the municipalities of Supía, Chinchiná, Marmato, and Riosucio. Paraguay also reports a relatively small number of infected people (almost 900) nationwide, mostly located in Central, Asunción, Paraguarí, and Amambay.

Because people infected with this virus often are not sick enough to seek medical care, they are not reported. The true extent of the spread of this virus remains uncertain.
