Objectives: Analyse from an epidemiological view the conjunctivitis epidemic in the BHU (Basic Health Unit) São Rafael, in Guarulhos, SP.
Materials and methods: We studied prospectively, patients with viral conjunctivitis treated at a Basic Health Unit (BHU) in Jardim Sao Rafael. Patients were assessed using standardized forms containing identifying and demographic data
age, sex, origin and place of residence), clinical history (signs, symptoms, intensity, duration), and the registration number of the family. Utilizing graphics, we evaluated the correlation between age and place of residence with the total number of cases. We carried out an epidemic curve from the date of onset of symptoms with the total number of cases.
Results: The conjunctivitis epidemic began in February 2011. In the BHU Guarulhos, the first cases suggestive of conjunctivitis were seen in referral centres for Ophthalmology. Due to the increased demand for care, the service flow was directed to the UBS of the reference cases. In the period between March 20, 2011 and April 4, 2011, 265 cases of conjunctivitis were treated in the UBS San Rafael. The majority of the Patients in the UBS were females, totalling 62.6%.
Conclusions: There was a predominance of viral conjunctivitis in females, with higher frequency in the age group of 10-19 years, with a concentration of cases in the area 42 of the UBS.
