Abstract
Since the first description of Middle East respiratory syndrome coronavirus (MERS-CoV), it has not been known how long patients shed the virus in respiratory secretions. Thus, we analyzed the available data on time to negative MERS-CoV test in patients with confirmed MERS-CoV infection and asymptomatic positive contacts.
Data from repeated laboratory testing of respiratory samples received at the Saudi Arabian virology reference laboratory in Jeddah, Kingdom of Saudi Arabia from September 1, 2012 to September 31, 2013 were recorded. A real-time RT-PCR test for MERS-CoV was used. Data were analyzed by origin of sample, sample type, and MERS-CoV PCR test results.
Twenty-six individuals (13 patients and 13 contacts) had repeated testing done until a negative test was obtained. Most samples from MERS-CoV cases were tracheal aspirate/sputum (
Contacts cleared MERS-CoV earlier than ill patients. This finding could be related to the types of sample as well as the types of patient studied. More ill patients with significant comorbidities shed the virus for a significantly longer time. The results of this study could have critical implications for infection control guidance and its application in healthcare facilities handling positive cases.
