Dear Colleague,\u00a0<\/span>\u00a0<\/span><\/p>\n

In collaboration with the Fairfax County and Loudoun County Health Departments, the Virginia Department of Health (VDH) is investigating a\u202fconfirmed case\u202fof dengue virus infection\u202fin a resident who did not have known travel outside of Virginia prior to illness onset. This is the first documented case of locally acquired dengue in Virginia. The patient is known to have been in close proximity to a recent internationally acquired case in a Virginian who was diagnosed a couple weeks pri<\/span>or.\u00a0Dengue viruses are spread to people through the bites of infected\u00a0<\/span>Aedes<\/span><\/i>\u00a0species mosquitoes.<\/span> Transmission of the virus likely occurred when a local mosquito bit the internationally acquired case while infectious and subsequently infected the second case.\u00a0\u00a0There is no evidence of continued transmission and no additional reports of locally acquired dengue cases at this time. <\/span>The potential risk for\u00a0acquiring\u00a0dengue virus in\u00a0Virginia\u00a0remains\u00a0low.<\/span><\/b>\u00a0<\/span>\u00a0<\/span><\/p>\n

VDH is working with local partners to monitor for any additional dengue cases and conduct surveillance of mosquitoes that can carry dengue viruses. <\/span><\/p>\n

Given this recent report of local transmission, providers should:<\/span>\u00a0<\/span><\/p>\n
