A/H1N1 flu cases in the Chinese mainland decreased last week, said the Ministry of Health Wednesday.

According to the ministry's weekly report, 2,935 cases were confirmed in the Chinese mainland from December 28, 2009, to January 3, 2010. The figure was down from 4,448 the previous week.

A/H1N1 cases also accounted for a smaller portion of flu cases, according to the report, taking up 68.5 percent of flu cases in the mainland, down from 78.8 percent the previous week.

As well, the people who died from A/H1N1 was down from 93 to 67.

However, the ministry said that people should still take care to protect themselves from the A/H1N1.

"We have seen an increasing number of expectant mothers who showed serious symptoms or died of A/H1N1 flu," the Ministry of Health stated. But the exact numbers were not given.

The ministry suggested that vulnerable people, especially pregnant women, should be vaccinated.

By Tuesday, a total of 51.38 million people had been vaccinated in the mainland.

The ministry also warned about increased possibility of catching bird flu in cold winter. People who have close contacts with birds and flu symptoms should see a doctor immediately, the statement said.
