Health officials say that by the end of 2014 there were 106 cases of the chikungunya virus confirmed in the country. Some 36 cases were of persons who contracted the disease outside the country, but 70 appear to have contracted the virus inside the country.
Most of the cases in the capital of San José are imported, health officials said. Some 86 percent of the cases are confined to three provinces, with Puntarenas having the most. Jacó, for example, had 21 cases, they said.
The virus is spread by the same mosquitoes that carry dengue, and the tactic is to get rid of the mosquitoes.
The Minister de Salud says it will intensify its efforts.
