OBJECTIVE: To determine the seroprevalence of SARS-CoV-2 antibodies among eye health professionals (EHCW) in the largest ophthalmology center in Guatemala and the factors associated with antibody positivity.

METHODS: We carried out a cross-sectional serological survey among all the staff of the largest ophthalmology center in Guatemala. Serum samples were collected and tested for total antibodies against SARS-CoV-2 using the Roche Elecsys Anti-SARS-CoV-2 immunoassay. Results were reported as reactive or non-reactive. Based on patient exposure, staff were divided into low risk (technicians, domestic and administrative staff) and high risks (nurses, ophthalmologists, anesthesiologists and optometrists). Among those with positive antibodies, they received a survey that included demographic characteristics, exposure to COVID-19, and related symptomatology. Logistic regression was used to determine factors associated with antibody positivity.

RESULTS: On November 25, a total of 94 healthcare workers were serologically surveyed, the mean age was 34.15 years (± 8.41), most (57.44%) were women. The seroprevalence was 18%, the majority (77%) were in the low risk group; while 64% at high risk tested negative. People with low exposure were five times more likely to have antibodies than those with high exposure (OR: 5.69; 95% CI 1.69-19.13). Age and sex were not associated with HIV status.

CONCLUSIONS: We found a similar seroprevalence of SARS-CoV-2 antibodies in EHCW to what has been reported in other healthcare groups. Seropositivity was higher among healthcare workers with less patient exposure, hence the likelihood of community transmission. has already been reported in other healthcare groups.
