Puerto Rico continues their steady increase in chikungunya cases reporting another 1,661 cases putting the island country’s total over 24,000.

While Mexico has only recorded 131 autochthonous cases of the mosquito borne virus,  an increase of nearly 50, all have been laboratory confirmed.

In Central America, Honduras saw an increase in approximately 3,000 cases and in the Caribbean, Jamaica reported another 150 cases.

In total for the Western Hemisphere, there has been 1,071,696 suspected and confirmed locally acquired chikungunya cases in the past 12 months.
