Over the past month, the hospital received nearly 70 patients with flu and 48 of them tested positive for A/H1N1.
The number of A/H1N1 cases in Hanoi will continue to increase because the weather is still very cold and wet and the epidemic is not expected to end until March.
The Ministry of Health recommended people take preventative measures to minimise the risk of infection.
