The pandemic H1N1 influenza virus is unexpectedly continuing to spread easily through the United States during the summer months, and health authorities expect a bump in transmission in about six weeks, when school goes back into session — perhaps two or three months earlier than is normally seen with seasonal flu.
"Every year, there is an increase in flu when children go back to school" and viruses are being shared in close quarters, Dr. Anne Schuchat, director of the Centers for Disease Control and Prevention’s National Center for Immunization and Respiratory Diseases, said Friday in a telephone news conference. "This year, it is already circulating in summer camps, military units and so forth, so we are expecting when school opens we will see [a bigger than normal] increase."
A 30-year-old male student enrolled in the United States has been confirmed as China’s second H1N1, or swine flu, case, and its first on the mainland, according to the information office of the Chinese Health Ministry.
“Bao” began his journey at St. Louis, Missouri, took a connecting flight at St. Paul, Minnesota, for Tokyo, Japan on May 7th, according to Xinhua state-run news agency.
Asian countries will increase stockpiles of medicine to fight the H1N1 flu virus and look at ways to share essential supplies in the event of an emergency, according to a statement drafted for a meeting Friday.
Health ministers from the 10-member Association of South East Asian Nations (ASEAN) plus China, Japan and South Korea will intensify cross-border cooperation and establish joint response teams to fight the spread of the virus, also known as swine flu.
According to the statement, the ministers were concerned that most of the production capacity for vaccines was located in North America and Europe and it was inadequate for a global pandemic.
MEXICO CITY (Reuters) – Mexico will resume normal business activity this week after its swine flu emergency eased, but the global flu alert triggered a trade dispute on Monday over bans on Mexican, U.S. and Canadian pork.
International tensions triggered by the new H1N1 virus, which contains mostly swine components with bits of human and avian influenzas, emerged after about 20 nations banned imports of pork, pigs and other meat from the United States, Canada and Mexico, the three most flu-affected countries.
Mexico, the epicentre of the new flu outbreak which has surfaced in 21 countries, declared it was winning the battle against the flu, which has killed 26 people in the Latin American oil producer nation.
The new H1N1 flu virus appears to be fairly widespread in the United States and seems to be hitting mostly younger people, with very few cases reported in people over 50, U.S. health officials said on Sunday.
“We think very few of the cases we have confirmed are in people over 50,” the U.S. Centers for Disease Control and Prevention’s Dr Anne Schuchat told reporters in a telephone briefing. “Whether this will pan out over the weeks ahead we don’t know.”
The CDC reported 226 cases of the new H1N1 swine flu virus and one death in 30 states. The CDC previously had confirmed 160 cases in 21 states.
New tests are being shipped to U.S. states that should speed up efforts to screen for the new flu virus that threatens to start a pandemic, health officials said on Thursday.
And a lab with the new test has been set up in Mexico in the hope of finding out how many of the 2,500 suspected cases are in fact the new strain of H1N1 swine flu.
“Now there is a lab that is up and running in Mexico that is able to do diagnoses,” Centers for Disease Control and Prevention acting director Dr. Richard Besser told reporters.
The first confirmed case of swine flu in Ohio has been found in a 9-year-old Ely Elementary School third-grader. The school will be closed all week, Superintendent Paul Rigda said late Sunday night.
The boy, whom officials did not identify, traveled to Mexico during spring break. While there, he spent time at a farm, a fair, a couple of different cities and in Mexico City, according to Elyria City Health District officials.
He got back from the trip last Monday and started having symptoms Wednesday. He went to EMH Regional Medical Center in Elyria on Friday with an elevated temperature and cold- and flu-like symptoms, Elyria City Health District Commissioner Kathryn Boylan said.
Mexican authorities sought to reassure citizens Saturday over a deadly new multi-strain swine flu, as the World Health Organization warned that the virus had “pandemic potential.”
The outbreak of the new virus transmitted from human to human that has killed up to 60 people and infected hundreds in Mexico and infected eight in the United States is a “serious situation” with a “pandemic potential”, the head of the World Health Organization said Saturday.
Researchers have discovered human antibodies that neutralise not only H5N1 bird flu, but other strains of influenza as well. They now hope to develop them into life-saving treatments.
The antibodies — immune system proteins that attach to invaders such as viruses —also might be used to protect frontline workers and others at high risk in case a pandemic of flu broke out, the researchers said.
HIV is evolving rapidly to escape the human immune system, an international study has shown.
The Nature study highlights just how tough it could be to develop a vaccine that keeps pace with the changing nature of the virus.
The researchers showed HIV was able to adapt rapidly to counter human genes controlling immune system molecules that can target it for destruction.
However, they stressed this would not affect the impact of anti-HIV drugs.
