Country of destination
Observed no. symptomatic cases exported
No. cases exported from source countries (95% CI); % likelihood for >1 exportation†
Italy‡ 0 0 (0–4); 1 0 (0–4); 18 NA 0 (0–4); 8
Malaysia§ 0 0 (0–4); 0 0 (0–4); 33 0 (0–4); 1 0 (0–4); 2

*The incubation period considered was 5.5 days (95% CI 3.6–10.2 days) (8). MERS-CoV, Middle Eastern respiratory syndrome coronavirus; KSA, Kingdom of Saudi Arabia; UAE, United Arab Emirates; NA, not available.
†Information on Middle Eastern visitors to France, Netherlands, and Greece was not available. Number of Middle Eastern residents visiting Algeria and Austria was not available by country of residence.
