Should the World Go to Rio?PRINCETON – When Rio de Janeiro was awarded the 2016 Olympic Games, the Zika virus had yet to reach Brazil.
Now, after billions of dollars have been invested in preparing for the Games, Rio de Janeiro state has the second highest number of suspected Zika virus infections.
The Zika virus is not new, but the strain that entered Brazil in 2013 is more dangerous than any known variant.
A study published last month in the New England Journal of Medicine has confirmed that when the virus infects a pregnant woman, it can impede brain development in her fetus – a rare condition known as microcephaly.
The Brazilian outbreak of Zika virus has been linked with a particularly devastating form of microcephaly known as fetal brain disruption sequence.
But how does staying at home help a pregnant woman if others bring the virus back from Rio?
With 500,000 people expected to attend the Olympics, that is likely to happen in several countries in which Aedes aegypti, the mosquito that can transmit the virus, is present.
But, as Amir Attaran, a professor of law and population health at the University of Ottawa, argued recently in the Harvard Public Health Review, the transmission of dengue fever, a virus that is related to Zika and transmitted by the same species of mosquito, declines but does not cease in the Rio winter.
No doubt it would, but that needs to be balanced against the risks of spreading a dangerous virus.
It is neither socially responsible nor ethical to ignore the risks that the Zika virus poses to adults and to children yet to be born.

Jumping VirusesScientists long anticipated that an influenza virus will spread - as now appears to be happening in Asia - from wild birds to humans, causing a pandemic.
All types of virus strains or variants exist - somewhat akin to dogs existing as different breeds.
When a virus has been associated with its host for a very long time, it mutates to a form that grows well without killing its host, which would be a pointless outcome from an evolutionary standpoint.
A well-understood example is that of influenza viruses in wild fowl, where the virus causes infections that are hard to detect.
But if an influenza virus jumps from, say, ducks to chickens, there may be lethal consequences.
The virus is not well adjusted to the chicken, and some strains of the virus "go berserk."
Our problem arose when we enabled the virus to move from its normal home into us, by "farming" civet cats and other animals.
This shows that the SARS virus has jumped species, from animals to man, on other occasions, with benign consequences.
It is also possible that - again by chance - a benign SARS virus from a civet cat mutated after it infected people, becoming highly virulent.
Both aspects of this scenario - a virus jumping to a strange host and then mutating to a devastating form - are familiar.
On occasion, however, the virus mutates to a lethal form that can kill almost 100% of its victims.
It is a highly virulent influenza virus such as this that is devastating chickens in parts of Asia.
That influenza virus has also "jumped" from the chickens to those who look after them, killing some people.
The chronic fear of health authorities is that, by chance, another avian influenza virus will mutate and spread from person to person to spawn a global pandemic.
