It began far from where the majority of New Jerseyans would ever look, as these things frequently do. On April 1, a Dutch-flagged cruise ship named the MV Hondius departed Ushuaia, Argentina, and sailed into the South Atlantic. The ship was headed for the kind of isolated locations that people pay a premium to visit. Passengers began becoming ill by the beginning of May. Eight instances in all, including three fatalities (a 38% case fatality ratio), had been documented as of May 8. The Andes virus (ANDV) has been identified in six instances that have been laboratory-confirmed as hantavirus infections. The tale ought to have remained at sea. It didn’t.
Earlier this week, the New Jersey Department of Health revealed that two citizens of the state are under observation, not because they were on the ship but rather because they had contact with an infected passenger when flying internationally. Neither has displayed any signs. Neither has yielded beneficial results. Both are situated inside the Andes strain’s maximal incubation period, which is effectively a lengthy and unpredictable 42-day window. It’s a peculiar medical limbo that doesn’t exactly seem like an emergency but also doesn’t feel like nothing at all.

The particular virus causing this outbreak is what makes it unique and something to be aware of without being alarmed. The majority of hantavirus cases in the US are caused by rodent contamination, which is a concern for campers and rural homeowners. The strain from the Andes is distinct. Health organizations on several continents are on edge because the Andes virus is the only known hantavirus that can spread among humans.
Transmission from person to person is still uncommon. It usually necessitates prolonged, close contact, such as that which occurs in homes, in intensive care units without the appropriate safety equipment, or sometimes in a cramped plane on a lengthy overseas flight.
This is not unique to New Jersey. Approximately eleven states in the United States have 41 individuals under observation for possible hantavirus infections. The majority are former cruise passengers in Atlanta and Nebraska under supervision. A smaller number, which includes the two in New Jersey, are being monitored from home after being exposed during repatriation flights. Officials have taken care to repeatedly state that there is very little risk to the general public. In and of itself, that recurrence serves as a signal. They want the tone of this article to remain peaceful.
Fairly or wrongly, it is difficult to ignore the similarities that people are already making to early 2020. The cruise ship. the tracing of international contacts. the gradual flow of confirmed cases. According to Cawcutt, the most important thing to understand is that hantavirus differs from COVID-19.
One sick person might infect numerous people at once, and the coronavirus was a novel virus that transmitted quickly among humans. In the meantime, the world’s medical community is familiar with the Andes strain of the hantavirus. In other words, this time, the science is in favor of containment. However, people’s memories are not as long as science’s, and the imagery alone might cause anxiety.

The reaction has been measured within New Jersey. The residents under observation, as well as the airports and planes concerned, have not been identified by state officials. There are no advisories, no run-on hand sanitizer, and no school closures.
The two residents are allegedly assisting with daily check-ins, and the Department of Health is working with the CDC and federal partners. What strikes me as I watch this develop is how ordinary everything appears from the outside. a few calls every day. a thermometer. The next six weeks are circled on the calendar.
Whether or not either resident exhibits symptoms throughout the incubation window will determine what happens next. The New Jersey part of this story will quietly end if they don’t. The calculus is altered if one of them does. “The Andes virus or hantavirus takes six to eight weeks to incubate. WHO Director General Tedros Adhanom Ghebreyesus told reporters this week, “So we actually expect more cases to come, but I hope they will be as small as possible.” That cautious optimism is most likely justified. However, there is a legitimate wait for two unidentified individuals in New Jersey.
