In 2009, a major worldwide H1N1 flu pandemic killed around 18,500 in 214 countries. In Brazil, there were 2,060 confirmed deaths. Since then, a vaccine for the disease, which is also known as “swine flu” ,has been developed and distributed in Brazil. Still, 2016 has been the worst year since the 2009 pandemic: 1,003 have already died from H1N1 – just last week, there were 117 deaths.
Almost half of the cases were registered in the state of São Paulo. In total, 5,214 cases of Acute Respiratory Distress Syndrome (ARDS), which is related to H1N1 infections, have been reported so far in 2016. According to the Ministry of Health, infections have been registered much earlier than usual this year, at wintertime.
