Resumo: Chikungunya - dengue are mosquito-borne, viral, acute febrile illnesses that can be difficult to distinguish clinically. Whereas dengue is endemic in many countries in the Caribbean - the Americas, the first locally acquired chikungunya case in the Western Hemisphere was reported from the Caribbean isl- of St. Martin in December 2013 - was soon followed by cases in many parts of the region. In January 2014, the Puerto Rico Department of Health (PRDH) - CDC initiated chikungunya surveillance by building on an existing passive dengue surveillance system. To assess the extent of chikungunya in Puerto Rico, the severity of illnesses, - the health care-seeking behaviors of residents, PRDH - CDC analyzed data from passive surveillance - investigations conducted around the households of laboratory-positive chikungunya patients. Passive surveillance indicated that the first locally acquired, laboratory-positive chikungunya case in Puerto Rico was in a patient with illness onset on May 5, 2014. By August 12, a total of 10,201 suspected chikungunya cases (282 per 100,000 residents) had been reported. Specimens from 2,910 suspected cases were tested, - 1,975 (68%) were positive for chikungunya virus (CHIKV) infection. Four deaths were reported. The household investigations found that, of 250 participants, 70 (28%) tested positive for current or recent CHIKV infection, including 59 (84%) who reported illness within the preceding 3 months. Of 25 laboratory-positive participants that sought medical care, five (20%) were diagnosed with chikungunya - two (8%) were reported to PRDH. These investigative efforts indicated that chikungunya cases were underrecognized - underreported, prompting PRDH to conduct information campaigns to increase knowledge of the disease among health care professionals - the public. PRDH - CDC recommended that health care providers manage suspected chikungunya cases as they do dengue because of the similarities in symptoms - increased risk for complications in dengue patients that are not appropriately managed. Residents of - travelers to the tropics can minimize their risk for both chikungunya - dengue by taking st-ard measures to avoid mosquito bites.
