Devi Sridhar analyses the worldwide public health response to the hantavirus outbreak linked to the MV Hondius, arguing that the crisis was averted because of a decisive, early diagnostic breakthrough.
The UK Overseas Territories (UKOTs) programme, funded by the Foreign Office and administered by the UK Health Security Agency, delivers health services to small, vulnerable communities worldwide that often lack adequate medical infrastructure. Its success relies on close communication and strengthening those services.
A perceptive physician on Ascension Island detected a cluster of suspected hantavirus cases after a sick passenger was taken ashore for treatment. Newly available diagnostic equipment allowed the exclusion of common illnesses, indicating an unusual pathogen.
A multinational meeting involving Ascension Island, the UKOT infection specialist, the ship’s medical adviser, and a colleague at the National Institute for Communicable Diseases in South Africa reviewed possible causes. Samples from two patients medevaced to South Africa were examined, resulting in a confirmed hantavirus diagnosis.
This timely identification alerted the World Health Organization and national public health agencies, averting disaster. Had the vessel proceeded to Cape Verde, passengers incubating hantavirus would have disembarked and spread the disease to their home countries, leading to a far broader outbreak.
