Middle East respiratory syndrome (MERS) first emerged in Saudi Arabia in September 2012. Until last month, most MERS cases have occurred in that country. But on May 20, South Korea reported its first laboratory-confirmed case of MERS, in a 68-year-old man who had recently returned from a business trip to the Middle East.

The diagnosis was made only after the man had visited four health care facilities since his return home. This resulted in nosocomial transmission to other patients, health care workers, and visitors. To date, the Republic of Korea’s Ministry of Health has identified 108 cases of MERS in South Korea. Nine patients (all with serious preexisting health conditions) have died.

The WHO notes that all of these cases are epidemiologically linked to the index case. That is, there is no evidence that a new “reservoir” of MERS virus has suddenly surfaced in South Korea—all cases thus far stem from the Korean traveler who acquired his infection while visiting the Arabian Peninsula.

This is the largest outbreak of MERS so far outside of the Middle East, and therefore a reason for some concern. However, person-to-person transmission of MERS is not new, and there has as yet been […]

MERS: A Lucid Overview of What Nurses Need to Know

In recent weeks, there have been a number of news stories following the first U.S. cases of Middle East respiratory syndrome (MERS-CoV) and the first transmission of the virus that occurred on U.S. soil. This novel coronavirus (the common cold is a coronavirus; so is SARS) can cause respiratory failure and death. So far, the number of identified cases are relatively few, though the numbers are growing. Disease surveillance has been aggressive since the first case was identified in Saudi Arabia.

Back in January, before the U.S. had seen its first cases, infection prevention specialist Betsy Todd provided a clear, engaging overview of MERS […]
