H1N1 flu has spread to 160 countries

Two billion people, about one-third of the world's population, will get sick within the next two years, the World Health Organization has just announced about the ongoing pandemic H1N1 flu.

The BBC reported that the current period is only the beginning of the flu.

Keiji Fukuda, a senior official of WHO, said the flu will continue to spread in the coming time, although the epidemic has begun for 4 months. About 800 people have died around the world. Fukuda also said, although the WHO continues to report positive test cases, this number is always the tip of a much larger iceberg.

Most of the current cases are in young people, ages 12 to 17, although some reports show that people in older ages are also hospitalized.

WHO also stated that there is increasing evidence that pregnant women are at higher risk for more severe cases. However, Mr Fukuda said the organization " certainly does not have any recommendations about whether women should be pregnant at this time ".

In Vietnam, before the reality, all countries in the world and in the region have had deaths, said Dr. Nguyen Huy Nga, Director of the Department of Medical Treatment (Ministry of Health): " When the epidemic has spread community is more difficult to control cases and the occurrence of H1N1 deaths is unavoidable ".

Cases of fatalities are those with chronic diseases, people with poor resistance, the elderly, children, pregnant women and obese people.

In Vietnam, the epidemic has spread to the community and started from school. The number of cases of influenza has reached 532 cases and has not recorded any cases of serious complications or death.

However, as more countries, the number of patients increases, the greater the likelihood of death. Estimated mortality rate is from 0.2 to 2%. Thus, with the lowest mortality rate of 0.2%, one person will die every 500 cases.

The number of deaths is not as high as other flu outbreaks, but is only equivalent to the regular seasonal flu that occurs every year. " But that doesn't mean we can ignore it. Because the 1918 pandemic A / H1N1 epidemic lasted about two years, 50 million people died, " he said.
