Key result
Diagnosing Coxsackievirus A24 in a returning traveller identifies the cause of an Indian Ocean outbreak.
Why the study?
The cause of an ongoing outbreak of acute haemorrhagic conjunctivitis in Indian Ocean Islands was unidentified due to limited laboratory investigation.
Case Report (n=1)
No
Returning travellers can serve as sentinels for identifying the etiology of infectious disease outbreaks in regions with limited laboratory capacity.
Supports sentinel surveillance by returning travelers for outbreak etiology; hypothesis-generating and needs validation in larger cohorts.
In May 2012, a Coxsackievirus A24 haemorrhagic conjunctivitis was diagnosed in Marseille, France, in a traveller returning from the Comoros Islands. This case allowed identification of the cause of an ongoing outbreak of haemorrhagic conjunctivitis in Indian Ocean Islands, illustrating that returning travellers may serve as sentinels for infectious diseases outbreaks in tropical areas where laboratory investigation is limited.

Aubry et al. (2012) conducted a case report in Coxsackievirus A24 haemorrhagic conjunctivitis (n=1). Travel to Comoros Islands was evaluated on Diagnosis of Coxsackievirus A24 haemorrhagic conjunctivitis. Diagnosis of Coxsackievirus A24 haemorrhagic conjunctivitis in a returning traveller allowed identification of the cause of an ongoing outbreak in the Indian Ocean Islands.
