SAN PAULO • Brazil, the country hardest hit by the Zika virus, is facing another health problem with the Olympics it is hosting just months away: a swine flu outbreak.
The outbreak of Type A of the H1N1 virus has killed 46 people in less than two months in Brazil. That is 10 times the figure for all of last year, the Health Ministry said.
In Rio de Janeiro, which will host the Games from Aug 5-21, the first fatality was reported on Thursday by health care authorities. Through March 19, 305 cases were reported throughout the country, compared with 141 in all of 2015.
A large majority - 260 cases, 38 of them fatal - were reported in the Sao Paulo region, the economic and financial engine of the now struggling South American powerhouse. People have been waiting in line for more than three hours outside some hospitals to get vaccinated.
In Brazil the H1N1 virus has normally appeared in recent years between May and July when temperatures are cooler. But this year it has caught health authorities by surprise as it began in February.
It is not clear why, but many doctors say it stems from Brazilians who travelled to the northern hemisphere in the first months of the year.
A major H1N1 outbreak sparked a World Health Organisation pandemic alert in June 2009, after the virus emerged from Mexico and the United States.
The epidemic killed around 18,500 people in 214 countries. The alert was lifted in August 2010. Since late 2015 Brazil has been at the epicentre of the Zika virus crisis.
