A fresh alert has been issued from the country at the centre of the outbreak of a virus which spread on a cruise ship.
Smarttraveller says hantavirus, which is spread through contact with infected rodents, "continues to be a risk in Argentina, including in and around Buenos Aires and northern Patagonia."
Three people have died as part of the outbreak.

"Avoid contact with live or dead rodents, nests, burrows and droppings," the update says.
Hantavirus usually spreads when people inhale contaminated residue of rodent droppings, and the disease is not easily transmitted between people.
But the Andes virus detected in the cruise ship outbreak may be able to spread between people in rare cases. Symptoms usually show between one to eight weeks after exposure.
Argentina remains a "green" country, which means to exercise "normal precautions."

Officials in Argentina's Tierra del Fuego province are challenging the idea that the ongoing deadly hantavirus outbreak may have emerged there, pushing instead for investigations into the other Argentine provinces that passengers visited before boarding the ill-fated Atlantic cruise ship.
Current and former officials in the archipelago at the southernmost point of South America insist that the virus did not originate from the trash heap in Ushuaia that national health authorities named earlier this week as the most likely place two Dutch tourists contracted it while bird-watching.

Meanwhile, Australians on board the ship will have to wait on the vessel, despite other passengers departing, as they await a flight home.
The four Australian citizens, one permanent resident and a New Zealand national are expected to leave the Canary Islands, where passengers have finally begun to disembark, later today and touch down in Perth on Tuesday.

A federal government spokesperson said Department of Foreign Affairs and Trade consular officers in Tenerife and Canberra had been closely coordinating the response while the Commonwealth and states are working through health and transport arrangements.
Three people have died since the outbreak, and five passengers who left the ship are infected with hantavirus, which can cause life-threatening illness.
More cases of a deadly, rodent-borne illness could emerge in the coming weeks but the risk to public health is "low", according to the World Health Organisation.
"This is not another COVID. And the risk to the public is low. So they shouldn't be scared, and they shouldn't panic," WHO Director-General Tedros Adhanom Ghebreyesus says.
