A trio of researchers from Johns Hopkins Aramco Healthcare, Aix Marseille University, and the University of Zürich has found that fans flocking to the World Cup in Qatar will be at risk of acquiring Middle East respiratory syndrome (MERS). In their paper published in the journal New Microbes and New Infections, Jaffar Al-Tawfiq, Philippe Gautret and Patricia Schlagenhauf, describe the risk posed by MERS and what visitors to the World Cup should do to help keep themselves infection-free.
