Health officials reiterated today that the new H1N1 virus continues to spread rapidly in the temperate zones of the hemisphere North and kill hospitalization unusual number of children, young adults and pregnant women. The need for vaccines and antivirals remains pressing in those countries, and demand exceeds supply. Confusion also complicates efforts to treat and prevent the disease.
Between 1% and 10% of people who develop swine flu require hospitalization, according to a review of current epidemiological data released today by the World Health Organization (WHO). The new data were discussed 27-29 October at a meeting of the Strategic Advisory Group of the WHO of Experts (SAGE) on immunization. Up to 25% of hospital patients are admitted to intensive care units, and between 2% and 9% die. Pregnant women account for 7% to 10% of hospitalized patients.
In a departure from formal recommendations addition, SAGE has announced that people regardless of age need only one dose of the H1N1 vaccine. The US Centers for Disease Control and Prevention (CDC) recommends that children under 10 receive two doses. After the European Agency Committee for Medicinal Products for medicinal products for human use meeting 19-22 October, the agency recommended that everyone regardless of age receive two doses of vaccine against pandemic influenza approved for use here . Certainly different vaccines are used in different places, but the differences reflect that data from clinical trials of different vaccines in a range of ages is still preliminary. And questions of dosing impact both the effectiveness of vaccines and their availability, since they are rare everywhere.
At a press conference held today by the CDC, its director, Tom Frieden, discussed the differences on children under 10 years CDC based its decision to children under 10 to receive two doses on preliminary data from clinical trials of the vaccines used in the United States, but he said more comprehensive data should emerge soon. "Throughout this entire response, our approach is, look at the data and monitor data," Frieden said.
Frieden also revealed new data on deaths in children.
to date, 119 children with confirmed infection of the new H1N1 virus have died of the disease in the US. this is 19 more than 1 week earlier, the biggest jump seen in a single week. the virus now widespread in all but two states, the more activity yet published. Although the spread has begun to decline in some places, Frieden stressed that "we do not know if this is a fall before a further wave. "
As of today, CDC has 26.6 million doses of vaccine against H1N1, and Frieden stressed that this is 10.5 million more than they had 1 week ago. CDC is also in the race to track requests pediatric formulations of anti-flu drug Tamiflu. It has now published its entire stock of liquid Tamiflu, which equates to 534,000 during the drug. CDC also encourages pharmacists to make syrup for children of drug capsules adults. If the parents can not get Tamiflu pediatric capsules, CDC said, too, can be mixed with the syrup at home.
