Acute Middle East Respiratory Syndrome Coronavirus Infection in Livestock Dromedaries, Dubai, 2014

Abstract: Camels carry Middle East respiratory syndrome coronavirus, but little is known about infection age or prevalence. We studied >800 dromedaries of all ages and 15 mother–calf pairs. This syndrome constitutes an acute, epidemic, and time-limited infection in camels <4 years of age, particularly calves. Delayed social separation of calves might reduce human infection risk.

“…More frequent sporadic introductions could be related to an increase in the virus circulation in the zoonotic source. A recent study (Wernery et al, 2015) on MERS-CoV spread among dromedary camels shows that the virus produces acute epidemics in calves, often born in Spring. Such outbreaks may cause an increase in the number of primary cases and increased opportunities for subsequent transmission, multiplying the number of admissions of MERS-CoV cases to hospitals with the possibility of further triggering hospital outbreaks as previously reported (Drosten et al, 2015;Saad et al, 2014;Oboho et al, 2015).…”

“…72,76e81 À Viable MERS-CoV was isolated from nasal and faecal samples from dromedary camels. 76,82 MERS-CoV recovered from dromedary camels is capable of causing ex-vivo infection in human respiratory cells. 83 À Acute infection in dromedary camels has been demonstrated by documented rises in anti-MERS-CoV antibody titres, and by RTePCR in symptomatic animals.…”

“…However, camels are believed to be an intermediate with speculation that bats could be the primary host . Dromedary camels were 80% to 90% seropositive, from samples dated back to as early as 1983, in African countries, Arabian Peninsula countries, and the Spanish Canary Islands, but 0% in Australian dromedary camels or Bactrian camels, and several groups reported viral shedding from infected camels . Nevertheless, despite the impressive and quick elucidation of many issues about MERS‐CoV, there are gaps in our understanding of this emerging virus, such as the precise route of transmission of camel‐to‐human infections, the risk factors for contracting the virus, and the protective level of neutralizing antibodies (nAb).…”
