In the January 2013 issue of Infectious Disease Alert the initial reports of a novel coronavirus were reviewed.1 These included 5 cases (including 3 deaths) from Saudi Arabia, two cases from Qatar and two cases (both fatal) from Jordan. Unfortunately, this potentially lethal virus has not disappeared, as the SARS coronavirus appears to have done, and a 15th case has been reported.
On 12 March 2013, the WHO reported that they had been informed by the Ministry of Health in Saudi Arabia of a new confirmed case of infection with the novel coronavirus (nCoV). A 39-year-old man became ill on 24 February 2013 and died on 2 March, several days after hospitalization. While the epidemiological investigation is incomplete, no link to previously reported cases had been identified. This patient was the 15th known case of nCoV infection; 9 have died.
Commentary
No cases of nCoV infection have yet been reported in the U.S. but 3 cases within one family in the U.K. have been confirmed. The index family in that cluster had traveled to Pakistan and Saudi Arabia. Investigation indicated person-to-person transmission within the family.
The Centers for Disease Control and Prevention recommends reporting the following to your health department:2,3

- Not already explained by any other infection or etiology, including all clinically indicated tests for community-acquired pneumonia* according to local management guidelines, AND
- Persons who develop severe acute lower respiratory illness of known etiology within 10 days after traveling from the Arabian Peninsula or neighboring countries* but who do not respond to appropriate therapy, OR Persons who develop severe lower respiratory illness who are close contacts of a symptomatic traveler who developed fever and acute respiratory illness within 10 days of traveling from the Arabian Peninsula or neighboring countries.
