Unvaccinated adults in Russia are being asked to stay at home for up to four months due to the country’s gastroenteritis epidemic.
Children under the age of two are also being asked to stay off school and other official activity.
The flu-like illnesses, which have struck in winter as well as during the summer, will continue until April.
However, temperatures are set to hit 30C in the summer months.
Experts fear a wave of infections could surface later in the year.
The country’s health ministry warned that “unvaccinated adults, aged over 60, should avoid meetings with friends, play or sport-related groups or go out alone”.

Health Minister Veronika Skvortsova said: “Young people aged below five should go to play with their friends, go to outdoor play in parks and spaces where they can enjoy themselves without bringing germs with them.”
“We want to prepare for the fall,” Skvortsova added.
Meanwhile, Russia’s T20 tournament is being postponed by two weeks and its top domestic league has been reduced to 12 games.
Covid-19, which was set to begin on Monday, has now been given until the end of June.

Russia recorded a large number of patients with gastroenteritis in January this year. The alert status was set last month at two level, high or a lower level.
Prevention against the virus was increased and a vaccination campaign was launched in April.
In 2018, the country recorded the third most cases of diarrhoea and vomiting after Thailand and India.
It is unclear what caused the current outbreak of gastroenteritis, but research by London-based Chatham House last year pointed out that the virus originated in Thailand in 2004 and has spread rapidly.
There have been significant outbreaks in Russia and Hong Kong since a wave of the gastroenteritis – which can be fatal in a small number of cases – swept through Malaysia in 2012.
Russia’s right-wing opposition leader Vladimir Zhirinovsky, who is known for his criticism of western medicine, said last month that several presidential aides may have died because they did not carry vaccinations.
