HEALTH EXPERTS CALL FOR CANCELLATION OF RIO OLYMPICS OVER ZIKA VIRUS

group of public health experts have urged the World Health Organization to consider whether the Rio de Janeiro Olympics should be postponed or moved because of the Zika outbreak.

An open letter to the UN health agency, signed by almost 150 public health experts, calls for the games to be delayed or relocated 'in the name of public health.' 

It cites recent scientific evidence that the Zika virus causes severe birth defects, most notably babies born with abnormally small heads. 

A group of almost 150 health experts have written an open letter to the World Health Organization calling for the Olympic Games in Rio de Janeiro to be canceled amid the threat of the Zika virus 

It comes as another top health official, said yesterday that the virus outbreak does not pose enough of a threat to warrant canceling or delaying the Games. 

Dr Tom Frieden, CDC director, said: 'There is no public health reason to cancel or delay the Olympics.'

A controversial paper by a Canadian professor published earlier this month in the Harvard Public Health Review called for the Games to be canceled or moved because it said they would likely speed up the spread of Zika throughout the world. Several health experts have disputed the report as lacking evidence for such a move.

'The risk to delegations going and athletes is not zero, but the risk of any travel isn't zero. The risk is not particularly high other than for pregnant women,' Dr Frieden said.

Zika infection in pregnant women has been shown to be a cause of the birth defect microcephaly and other serious brain abnormalities in babies.

The World Health Organization has also said there is strong scientific consensus that Zika can also cause Guillain-Barre, a rare neurological syndrome that causes temporary paralysis in adults.

The connection between Zika and microcephaly first came to light last fall in Brazil, which has confirmed more than 1,400 cases of microcephaly that it considers to be related to Zika infections in the mothers.

Putting the Olympics risk in perspective, Dr Frieden said travel to the Summer Games would represent less than one quarter of one percent of all travel to Zika affected areas.

The CDC director called on Congress to deliver funding needed to fight Zika globally and to protect pregnant women in the United States and its territories, such as Puerto Rico, where officials expect hundreds of thousands of Zika cases.
