ULAN BATOR, Dec. 12 (Xinhua) -- The World Health Organization (WHO) donated more than 5,000 doses of flu drug Oseltamivir to Mongolia on Thursday.

Sergey Diorditsa, representative of the WHO in the country, handed over the antiviral medication worth 25,000 U.S. dollars to Davaajantsan Sarangerel, Mongolian minister of health.

"Influenza, an infectious disease of the respiratory system, represents a major burden for public health. The medication donated by the WHO will be given to children, pregnant women and seniors in public hospitals in the capital city," Sarangerel told reporters.

Prevalence of influenza and other respiratory diseases is now relatively low in the Mongolian capital thanks to the implementation of some preventive measures of flu and the reduction of air pollution in Ulan Bator, she said.

The drug was distributed to several public hospitals in the Mongolian capital.
