Russia's first case of A/H1N1 flu has been recorded in Moscow, the Interfax news agency reported on Friday.

A 28-year-old Russian national returning from New York was tested positive for the A/H1N1 flu virus, Interfax reported, citing the country's Chief Public Health Official Gennady Onishchenko.

The patient "has no fever" and "is in a satisfactory condition," Onishchenko said.

The official said everyone who had contact with the patient had been put under observation.

More than 6,000 people had undergone medical checkups at Russian airports for the past 24 hours after arriving from A/H1N1 flu-stricken countries, he added.

Russian medical authorities have also recommended that Russians avoid trips to the United States, Mexico, Canada, Spain, and some of the regions in Japan.

A senior Russian lawmaker said on Wednesday that Russia was actively developing a vaccine against the flu virus. Local media reports said the vaccine would be available in coming months.

According to the World Health Organization and governments' data, the confirmed deaths worldwide reach 89 on Friday, with 78 in Mexico, nine in the United States, one in Canada and one in Costa Rica.

The confirmed cases worldwide are more than 11,000 in 43 countries and regions, most in the United States and Mexico.
