Almost all Puerto Ricans follow the protocols against COVID-19

San Juan. The population study PREPCOVI (Puerto Rico-Epidemiological Evaluation and Prevention for COVID-19 and Influenza) of the Medical Sciences Campus (RCM) of the University of Puerto Rico (UPR) today revealed new research findings that, so far It has had 1,774 participants from the Island.

“We call on citizens to participate in this study. Any citizen could receive a text message on their cell phone inviting them to participate in this PREPCOVI study. Pressing the link would initiate a survey, which we ask you to complete so that, in Puerto Rico, we can have better data and thus more effectively prevent COVID and Influenza. Completing this form is a way to contribute to the public health of Puerto Rico ”, explained Dr. Segundo Rodríguez Quilichini, Rector of the RCM.

At the moment, the majority of respondents (68.5%) are women. The participants ranged from 21 to 92 years of age and 75 of the 78 municipalities of Puerto Rico are represented. According to preliminary results, men and people over 65 were more likely to have been classified as a COVID-19 case and to be a confirmed case.

On the other hand, the geographic distribution of confirmed cases suggests higher numbers in the eastern region of Puerto Rico. While the total cases (confirmed and / or probable) were higher in the Northeast region. 4% of all cases reported symptoms lasting more than 21 days. None of the cases with COVID-19 reported receiving hospitalization services, Intensive Care Unit or oxygen treatment. The most frequent symptoms reported of the confirmed and / or probable cases with COVID-19 were loss of smell (52%), loss of taste (50%) and fever (43%). It should be noted that confirmed and total cases suggest to be higher among people with diabetes. While confirmed cases were highest among people with respiratory conditions and total cases were highest among obese people.

“We need more data to be able to establish more accurate associations between comorbidities and COVID-19. Therefore, these data should be considered descriptive. Our goal is to have 10,000 participants per month to have more accurate data, ”said Dr. Kaumudi Joshipura, principal investigator and professor at the RCM School of Dental Medicine.

This project has the support of the Telecommunications Bureau, telecommunications companies and the Department of Health. Potential participants will receive a text message from (787) 493-9302 like this: “PREPCOVI: UPR and the Department of Health invite you to participate in the anonymous 5-minute survey evaluating COVID-19 and Influenza. Click here to participate… “. It is important for citizens to know that this message does not have any risk, and is safe, since information that identifies the participant or their phone number is not retained.
