OBJECTIVE: To carry out the epidemiological analysis of 122 influenza A (H1N1) deaths confirmed by laboratory and help to improve the diagnosis and timely managing of cases. MATERIAL AND METHODS: A total of 122 clinical records were analyzed of patients with confirmed influenza A (H1N1) virus infection who died. RESULTS: Fifty-one percent of patients were female and 49% were male. A total of 45.l% who died were between 20 and 39 years old. Overall fatality was 2.2% and ranged between 0.3% for the l0 to l9 year-old group to 6.3% for the 50 to 59 year-old group. Forty-three percent of deaths were concentrated in only two of the thirty-two states and 5l% received medical attention in social security institutions. Only l7% received hospital attention within 72 hours and 42% died within 72 hours of hospital attention. DISCUSSION: Novel Influenza A (H1N1) virus produces higher mortality in young people whereas seasonal influenza has a greater impact on young children and older people. Delay in medical care and the associated morbidity were relevant factors for death.
