Other notable health concerns in 2014 included a significant increase in polio cases, particularly in Pakistan, which reported 306 cases in 2014, a dramatic rise from 93 cases in 2013 and a escalation of the MERS outbreak, after major outbreak occurred in Jeddah, Saudi Arabia, from March to May 2014.
