Study warns of longer incubation for Sars-like virus
PARIS (AFP) - The incubation period of the severe acute respiratory syndrome (Sars)-like virus that has killed 27 people globally, mainly in Saudi Arabia, may be longer than previously thought, requiring longer quarantine, a study said on Wednesday.
The Middle East Respiratory Syndrome coronavirus (Mers-CoV) may have an incubation - the period between infection and symptoms - of nine to 12 days, longer than the one-to-nine day period previously observed.
This finding had "important implications for the duration of the quarantine required to rule out infection among contacts" of the patient, said the study in The Lancet medical journal.
People who return from the Middle East with respiratory ailments, or who had been exposed to a confirmed Mers case, should be isolated, said the team and recommended a period of at least 12 days to confirm they were clear of the virus.
