The 2016 Rio Olympics seems to be encircled in danger as Zika virus poses a threat to all the foreigners visiting Rio De Janerio. It could cause a global health disaster.

Dr Amir Attaran, Faculty of Medicine and Faculty of Law at the University of Ottawa, wrote in a Harvard Public Health Review, that the Olympics could pace up the spread of the virus.

In a report by Independent, Attaran said: “ While Brazil’s Zika inevitably will spread globally, given enough time, viruses always do – it helps nobody to speed that up.”

“In particular, it cannot possibly help when an estimated 500,000 foreign tourists flock into Rio for the Games, potentially becoming infected, and returning to their homes where both local Aedes mosquitoes and sexual transmission can establish new outbreaks,” he added.

The Rio Olympics will begin on August 5 and will end on August 21.

The virus has is a serious flurry of problems for Brazilian officials. Despite, the World Health Organization declared the global health emergency, the game is the core concern for Brazil.

According to Think Progress, in January, the International Olympic Committee declared Rio “a safe place for games”. And after February, an Olympic spokesperson said: “We are sure this battle can be won and will not affect the Games.”

However, the unwavering Attaran said that “there is no guarantee” that the virus will recede in August.

Brazilian soccer legend, Rivaldo Vítor Borba Ferreira, suggested that tourists skip this Olympics.

“Things are getting uglier here every day,” said Ferreira.

“I advise everyone with plans to visit Brazil for the Olympics in Rio — to stay home. You’ll be putting your life at risk here. This is without even speaking about the state of public hospitals and all the Brazilian political mess. Only God can change the situation in our Brazil.” he added.

Zika is believed to cause microcephaly; a kind of abnormality and other fatal brain defects. The symptoms of the virus are fever, rash, joint pain, and red eyes.

Rio de Janerio has reported around 26,000 cases of Zika; more than any other Brazil state. It is one of the most epidemic regions engulfed in the virus.
