EPI AID No. (if applicable):	2014-060
Requesting entity (e.g., jurisdiction):	Puerto Rico Department of Health
Title of Investigation:	Undetermined burden of disease and risk factors for chikungunya virus infections—Puerto Rico, 2014
Purpose of Investigation: (Use as much space as necessary)	The EpiAid Team in collaboration with PRDH completed the following: 1) Conducted cluster investigations around the case-patients' homes. Information obtained included: a) detection of chikungunya cases that would not otherwise have been detected by passive surveillance; b) identification of the health care-seeking behaviors of patients; c) description of the clinical spectrum of disease across age groups; d) estimation of the level of DENV circulation in areas with known CHIKV transmission; e) entomologic surveillance to determine vector density and the frequency with which adult mosquitoes are infected with DENV and/or CHIKV; and f) identification of household and individual risk factors for infection with CHIKV. 2) Established sentinel chikungunya surveillance sites. Because most chikungunya case-patients are likely to only need out-patient care, we established sentinel surveillance sites in outpatient clinics and emergency departments to detect acute febrile illnesses consistent with chikungunya. These sites along with data from the sentinel enhanced dengue surveillance system (SEDSS) enable tracking of the outbreak and estimation of disease incidence. 3) Provided messaging, alerts and educational material for clinicians and the public. 4) Provided recommendations on vector surveillance and control mechanisms to monitor and mitigate the mosquito vectors that transmit CHIKV. 5) Conducted a rapid assessment of hospital needs to ensure availability of necessary medications (IV fluids, pain medication, antipyretics, etc.).

Chikungunya_Household Interview Form

Type of Respondent

General public Healthcare staff Laboratory staff Patients Restaurant staff
Other (describe):

Data Collection Methods (check all that apply)

Epidemiologic Study (indicate which type(s) below)
Descriptive Study (describe):		Performed household investigations to identify demographic, geographic, or behavioral risk factors for infection, health care-seeking behaviors of infected individuals, and clinical awareness and diagnosis of patients with chikungunya to help direct public and clinical mitigation efforts including reducing mosquito exposures and vector control.
Cross-sectional Study (describe):
Cohort Study (describe):
Case-Control Study (describe):
Other (describe):
Environmental Assessment (describe):	Households offered mosquito traps to be placed on the presmise of their household to determine the relative abundance of mosquitoes and the % of infected mosquitoes. No data were collected from households where traps were placed beyond what was collected on the household investigation form.
Laboratory Testing (describe):
