A total of 46 U.S. states and Washington D.C. faced widespread flu activity as production delays continued to hamper distribution of swine influenza A/H1N1 vaccine in the country, said a U.S. health officials on Friday (23/10).
"We are now in the second stage of epidemic influenza," said Director of the federal agency Centers for Disease Control and Prevention (CDC) Thomas R Frieden in Atlanta, at a briefing.
"Forty-six states reported widespread activity," he added.
Statistical data released by the CDC, Friday, showed that the state did not face widespread flu activity are Connecticut, Hawaii, New Jersey, and South Carolina.
Since the beginning of the spread of H1N1 flu in April and May, according to the CDC director, more than 1,000 deaths from the virus and more than 20,000 people in hospital have been recorded across the country.
A CDC poll released Thursday found that one in five children in the U.S. flu-like disease early in October, and most cases were suspected to be a swine flu A/H1N1.
"We estimate that influenza will spread in several waves. We can not predict how high, how far or how long the wave will occur or when the next wave will come," said Frieden.
When the American people are demanding H1N1 flu vaccine, the production delay a few weeks after the vaccine schedule because it grows more slowly on egg-based activities compared with the creators had expected, resulting in fewer doses.
"Until Friday, there were 16.1 million doses in the entire country, up from 14.1 million on Wednesday," said Frieden.
"It's disappointing for us all. We are now not be where we expected. We're nowhere near that predicted the vaccine makers," he said.
Due to production delays, the government should retreat from the optimistic early estimates that as many as 120 million doses of vaccine will be available in mid-October.
"What have we learned in more than two weeks later is not the only virus that can not be predicted, but the vaccine production forecast was far from our expectations," said Frieden told reporters.
Flu virus must be developed in chicken eggs and the results are not as much as originally expected, CDC officials said. "Even if you berate them, they would grow faster," said Frieden.
Plus a spread of H1N1 virus vaccine production delays which can not be predicted to make complex CDC strategy against a second wave epidemic.
"Is this going to continue until the autumn and into winter, whether it will disappear and return in the winter, only time will tell," said Frieden.
