We've increased our use of insect repellent the last couple of months and so far so good...neither one of us has had chikungunya. There are affordable brands here that work well...we've been using Bunny's brand which is priced under 400J.

The ministry had already been fogging previously around Negril & other areas...which may be a factor, along with hotels doing they're own fogging, in keeping the number of cases fairly low in Negril.
Recently, we've had the national emergency called...which thankfully frees up more money to continue to keep the mosquitoes at bay, etc.
