The recent hantavirus outbreak on the MV Hondius cruise ship has raised concerns about the potential spread of the deadly virus beyond the ship. The case of a Manhattan resident who was on the ship and traveled freely after leaving it highlights the challenges in containing the virus and the importance of effective communication between health authorities. The resident, a dual citizen of New Zealand and the United States, was one of 30 passengers who left the ship while it was docked at Saint Helena, in the South Atlantic, after one passenger had already died of the hantavirus. The CDC did not warn public health authorities in New York of her potential exposure to the virus, despite the fact that she had residences in Manhattan and Fort Lauderdale, Florida. This lack of communication raises worrying questions about the potential spread of the disease and the effectiveness of the CDC's response to the outbreak. The resident's ability to continue traveling and the lack of notice issued to authorities in the location to which she might eventually return further compound the problem. The hantavirus outbreak has also been linked to extreme travelers who are part of a subculture that centers around relentless jetsetting. These travelers have been found to have trekked globe-spanning itineraries since the outbreak was revealed, making it difficult to contain the virus and identify all potential exposures. The profile of the passengers themselves also complicated the picture, according to Alina Chan, a molecular biologist and co-author of "VIRAL: The Search for the Origin of Covid-19." The cruise selected for these extreme travelers, and you cannot ask for a potentially better superspreader. If one of the passengers presented to an international hospital with symptoms without the hospital being aware of their exposure on the ship, by the time the hospital would know, healthcare workers could have already been exposed. The CDC has been accused of a slow response to the outbreak, holding its first briefing on the crisis on May 9, a week after the WHO announced that the deaths were caused by the rare Andes strain of hantavirus. The incubation period for the Andes virus is anywhere from four to 42 days, raising concerns that the traveler and others who left the ship prior to the outbreak becoming known could transmit the virus to others if they become sick. The timing of the communications between the CDC and the WHO, and how they unfolded, are also unclear, as the case of this woman reveals. The WHO should make a list of all passengers available to all countries so they can be aware of visitors with exposure, rather than rely on each country. The case of the Manhattan resident highlights the need for effective communication and coordination between health authorities to prevent the spread of the hantavirus and other deadly diseases.
