A case-crossover analysis of the impact of weather on primary cases of Middle East respiratory syndrome	2019-02-04		.txt	text/plain	4352	220	48	METHODS: A case-crossover design was used to identify associations between primary MERS cases and preceding weather conditions within the 2-week incubation period in Saudi Arabia using univariable conditional logistic regression. Data from meteorological stations closest to the largest city in each province were used to calculate the daily mean, minimum, and maximum temperature ((ο)C), relative humidity (%), wind speed (m/s), and visibility (m). Middle East respiratory syndrome coronavirus (MERS--CoV) is an emerging zoonotic agent that was first isolated in 2012 from a patient hospitalized in Saudi Arabia [1] , and has since infected over 2200 people with a 36% case fatality ratio [2] . By comparing weather conditions immediately before MERS cases to weather conditions at other times, this study aimed to identify environmental factors that are associated with primary human MERS in Saudi Arabia. The risk of primary human cases of MERS was associated with a decrease in temperature and humidity, and an increase in ground visibility.	./cache/cord-267090-jc1k3fki.txt	./txt/cord-267090-jc1k3fki.txt
