During the 1920s, the PRDH
collected additional health-related data and compiled statistics, including those for TB.
Implementation of a sample transport system and establishment of alternative reporting methods allowed PRDH
to reinitiate diagnostic testing and laboratory surveillance and helped guide patient and public health interventions.
In December 2015, the Puerto Rico Department of Health (PRDH
) reported the first locally acquired case of Zika virus infection and as of July 29, 2016, 5572 cases have been confirmed .
Moreover, they expressed the opinion that the population of Puerto Rico is too large for the PRDH
to conduct these house visits.
The system's conversion and maintenance have become the overriding concerns of a PRDH
with diminished prevention resources that depend on federal funding.

has widely disseminated information to the public regarding avoiding mosquito bites to prevent Zika virus infection.
In May 2017, when only 10 new cases of Zika were reported in the island, the PRDH
declared an automatic end of the epidemic.
Given potential additional exposures, PRDH
and CDC undertook contact investigations among additional community and family members (N = 32) and hospital personnel (N = 39) to identify persons who required PEP After the contact investigations, two additional family members and two hospital staff members received PEP.
