A Muslim pilgrim wears medical mask as he walks in Arafat near the holy city of Mecca, Saudi Arabia, Monday, Oct. 14, 2013. This year some pilgrims and security personnel are wearing masks as a precaution against the Middle East respiratory syndrome, which has stricken nearly 100 people, most of them in Saudi Arabia and the Middle East. The Saudi health minister, Abdullah al-Rabiah, said late Saturday that no cases of the coronavirus infection have been detected among pilgrims.
This lesser-known tick-borne virus has no specific treatment and can be deadly. The CDC reports that only about 75 cases of this virus have been recorded in the United States over the past 10 years, mostly occurring in the Northeast and Great Lakes.
This mosquito-borne illness has been linked to a spike in brain defects in children and paralysis in adults. This virus is transmitted through the bite of infected Aedes mosquitoes -- the same mosquitoes that spread dengue and chikungunya viruses.
The first case of this virus was detected in Uganda in 1937. This virus was found in the United States in 1999. Most humans infected with this virus, which is transmitted through the bite of an infected mosquito, have no symptoms, while some may have a fever, headache and body aches. One in 150 people infected with this virus will develop neuroinvasive disease.
