Abstract
|
|
|
Since the first reported Middle East respiratory syndrome (MERS) human infection in 2012, MERS cases have been reported annually, mainly in the Arabian Peninsula. In 2019, according to the Ministry of Health in Saudi Arabia and the World Health Organization(WHO), a total of 222 MERS cases were confirmed with 59 MERS-related deaths. The cases were reported from 4 countries; Saudi Arabia, United Arab Emirates, Oman and Qatar.
Oman reported two clusters with thirteen confirmed cases in January and February, and UAE and Qatar identified sporadic
cases with one case and three cases, respectively. In Saudi Arabia, the number of cases from February to April was relatively high because four hospital-related outbreaks were identified in Riyadh and Eastern provinces. In particular, 86.1% of the secondary cases were reported in this period. Most MERS confirmed cases in Saudi Arabia were male (80.5%), and had underlying diseases (67.8%), with a mean age of 53.0 and a fatality rate of 27.3%. The highest fatality rate was demonstrated in hospitalized patients (50.0%). The overall outbreak situation and epidemiological characteristics in 2019 were similar to those of 2018. Since MERS imported cases from affected areas continue to pose a public health threat, early detection of confirmed cases and rapid response are key in preventing further spread.
