However, the health ministry announced on Tuesday that it expects the outbreak to start declining this week. All but the initial infection were transmitted in hospitals – the emergency department of Seoul’s Samsung Hospital alone accounted for 10 new cases last week. That means the virus should be contained by better hospital hygiene, and by isolating the contacts of people who have been infected. Nearly 3000 people are already in quarantine. That makes MERS less dangerous than SARS, a related virus that emerged in China in 2003 and spread worldwide because it was able to pass between people fairly easily.

This means it is more likely to become a troublesome hospital infection, like the antibiotic-resistant bacteria MRSA, than a pandemic – unless it evolves to transmit better in people. A genetic analysis published this week found the Korean virus was virtually identical to Saudi strains, suggesting that it hasn’t evolved. Since 2012,
