Objective: To know the frequency of flu symptoms and describe preventive measures practiced by the inhabitants of Mexico City during the AH1N1 epidemic.
Material and methods: A cross-sectional design was used and a survey containing demographic and health information was conducted in August and September 2009 in a sample of 4003 randomly selected people living in Mexico City.
Results: Referred flu symptoms were: 29% running nose, 25% cough, 25% throat infection, 17% muscle and joint pain, 10% respiratory problems, and 7% fever. Also 16% said having hypertension, 10% diabetes, and 2% morbid obesity. Among the preventive measures, 74% washed hands, 32% covered the nose and mouth with the forearm when coughing or sneezing, 28% used sanitizer gel five times a day in average, and 47% did not greet with a kiss or handshake.
Conclusions: Almost all the population followed preventive measures and did not show high percentages of influenza symptoms. Useful elements for prevention were identified, such as the frequency of seasonal influenza vaccination, self-medication, and living with a person diagnosed with AH1N1. It is important to continue with mass communication to strengthen adequate hygiene and health measures.
