Russia confirmed its second case of A/H1N1 flu on Sunday, the Itar-Tass news agency reported, citing the country's chief public health official.

The new patient, who returned with his wife from a trip to Dominica recently, tested positive for A/H1N1 flu, Gennady Onishchenko said.

The man was quarantined in hospital and was in a stable condition, Onishchenko said.

Those who came into contact with the man were under medical observation, and his wife and relatives have not shown any symptoms, the official said.

A 28-year-old man, who arrived in Moscow from New York, has been confirmed as the first case with A/H1N1 flu in Russia on Friday.

More than 12,000 A/H1N1 flu infections and 86 deaths have been recorded worldwide, according to the latest World Health Organization statistics.
