This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Key PointO_ST_ABSIMPORTANCEC_ST_ABSThe emergency of COVID-19 requires the implementation of urgent strategies to prevent the spread of the disease, mainly in health personnel, who are the most exposed and has the highest risk of becoming infected with the SARS-COV-2. Drug repurposing is a pragmatic strategy, a faster and cheaper option, compared to the new drug development that has proven successful for many drugs and can be a key tool in emergency situations such as the current one that requires quick action. In addition, considering the limited access to vaccines for developing countries, preventive use of ivermectin can be a palliative that minimizes the risks of infection. OBJECTIVETo evaluate the protective effect of the combination Ivermectin / Iota-Carrageenan (IVER/IOTACRC), intensive treatment with repeated administration in oral- and nasal-spray, respectively, as a prophylaxis treatment prior to exposure to SARS-CoV-2, in health personnel at Public Healthcare Centers. PARTICIPANTS, DESIGN AND SETTINGRandomized controlled 1-1 clinical trial in Personal Health, n = 234. The subjects were divided into experimental (EG n=117; 39.6 {+/-} 9.4 years old, 65F) and control groups (CG n=117; 38.4 {+/-} 7.4 years old, 61F). The EG received Ivermectin orally 2 tablets of 6 mg = 12 mg every 7 days, and Iota-Carrageenan 6 sprays per day for 4 weeks. All participants were evaluated by physical examination COVID-19 diagnosed with negative RT-PCR at the beginning, final, and follow-up of the protocol. Differences between the variables were determined using the Chi-square test. The proportion test almost contagious subject and the contagion risk (Odds Ratio) were calculated using software STATA. The level of statistical significance was reached when p-Value < 0.05. RESULTThe number of subjects who were diagnosed with COVID-19 in EG was lower, only 4 of 117 (3.4%) than subjects in CG 25 of 117 (21.4%) (P-Value = 1.10-5). Nineteen patients had mild symptoms, 4 were in EG whereas, 15 were in CG (p-Value = 0.001). Seven subjects were moderate, and 3 with severe diagnostics, all them in CG. The probability (Odds Ratio) of becoming ill with COVID-19 was significantly lower in EG with values of 0.13, 95% 0.03 to 0.40; p-Value = 1.10-4, this value (<1) indicates a protective effect of the IVER/IOTACRC in the EG. Logistic regression test demonstrated that treatment was effective to prevent COVID-19 (Odds Ratio 0.11, 95% 0.03 to 0.33; p-Value = 1.10-4). We also found that when increase the age, decrease contagious risk (Odds Ratio 0, 93, 95% 0.88 to 0.98, p-Value= 0, 02). On the other hand, the probability of contracting COVID-19 was dependent on the patients preexisting comorbidity (Odds Ratio 5.58, 95% 2.20 to 14.16, p-Value = 1.10-5). The other variables sex and designation were independent. CONCLUSIONThe intensive preventive treatment (short-term) with IVER/IOTACRC was able to reduce the number of health workers infected with COVID-19. This treatment had also effect in preventing the severity of the disease, since all patients treated were mild. We propose a new therapeutic alternative for prevention and short-term intervention scheme (intensive) that is of benefit of the health worker in this pandemic accelerated time. This intervention did not produce lack of adherence to treatment or adverse effects. Trial RegistrationClinicalTrials.gov Identifier NCT04701710
