Coronavirus: Fishermen test positive despite spending 35 days at sea and testing negative before they left

Argentinian health officials are scrambling to understand how nearly every crew member of a ship which spent 35 days at sea were found to have contracted coronavirus upon returning to land.

All 61 sailors aboard the trawler, Echizen Maru, tested negative for the virus upon departure from Buenos Aires in late May.

They were then flown to the Ushuaia, a typical jumping-off point for Antarctic voyages nicknamed “the end of the world”, where they were quarantined in a hotel for two weeks before setting sail.

After weeks at sea, some crew members started to display symptoms typical to Covid-19, and the ship returned to port.

All but four aboard the ship tested positive upon their return, local health authorities in the Tierra del Fuego province said on Monday. Two have been hospitalised in Ushuaia Regional Hospital, one of whom is receiving oxygen.

Now officials are struggling to piece together how the disease reached the isolated ship.

“It’s hard to establish how this crew was infected, considering that for 35 days, they had no contact with dry land,” Alejandra Alfaro, the director of primary health care in Tierra del Fuego, told Agence France-Presse. “Supplies were only brought in from the port of Ushuaia.”

“[The virus] entered somewhere. We have to think that it was human contact or contact with merchandise, products, supplies,” Ms Alfaro told local media on Monday.

“We know that for 35 days, no one, or any new input, got on the ship. Obviously something happened, perhaps there has been some degree of contagion inside the boat that was not registered.”

Ms Alfaro added that the outbreak may have been exacerbated by the fishermen’s hardiness and acclimatisation to rough conditions, in that they may have spent significant time in discomfort without recognising or acknowledging symptoms.

It is also possible that the two-week quarantine period was insufficient, with several studies having suggested that in rare cases – roughly one in every 100 – the incubation period can extend beyond 14 days.
