As dengue cases break international records, U.S. health officials warned doctors Tuesday to be alert for the mosquito-borne virus, prompting questions about where exactly the disease has been detected.Officials note there is no evidence of a current outbreak, but so far this year there have been three times more cases than at the same point last year in the 50 states — mostly from infections travelers got abroad.
'Part of what we're seeing now is with climate change — with increasing areas that are hot, humid, which are friendly to mosquitoes, where mosquitoes breed — we're seeing more transmission of dengue,' Gounder said.If you're traveling, Gounder suggests taking precautions. 'Stay in places that have air conditioning or have screened windows, where your exposure is going to be less. Use insect repellents with DEET or picaridin,' she said.
