Swine flu mutating
$this->bbcode_second_pass_quote('', 'G')ermany's federal agency for infectious diseases said on Tuesday there were signs the H1N1 swine flu virus had started to mutate and warned it could spread in the coming months in a more aggressive form.
Experts were concerned about how the flu was developing in Australia and South America, said Joerg Hacker, head of the Robert Koch Institute for infectious diseases.
"It's possible the virus has mutated. In autumn the mutated form could spread to the northern hemisphere and back to Germany," Hacker told a news conference in Berlin.
The World Health Organization raised swine flu to pandemic status earlier this month.

Within a few days, the 15-year-old student at Harvey Austin School 97 on Sycamore Street arrived seriously ill at Women & Children’s Hospital and then died Saturday, making him the first known fatality in Erie County caused by swine flu, officially known as novel H1N1 influenza.
By the time Matthew entered the hospital, he was seriously ill with the flu, as well as co-infected with a type of bacteria known as methicillin-resistant staphylococcus aureus, or MRSA, according to health officials.
Three children remain hospitalized in Women & Children’s with the new strain of the flu, including a 9-year-old student at Charles Drew Science Magnet School 59 in critical condition. Matthew and the 9-year-old also were infected with MRSA when they were admitted to the hospital.
“Both children were unusually ill with severe lung disease, and both required ECMO, and that was unusual,” said Dr. Howard S. Faden, chairman of infection control and director of virology at Women & Children’s.
ECMO, or extracorporeal membrane oxygenation, is similar to a heart-lung bypass machine utilized in open-heart surgery and is used when patients fail to respond to a respirator or other typical treatments for breathing problems. Under ECMO, the patient’s blood receives oxygen from an artificial lung.
An estimated 92 children die annually in the United States from regular influenza, according to the federal Centers for Disease Control and Prevention, and some of those deaths have been associated with coinfection with MRSA. As such, officials at the federal agency said last month they are closely following the development of the new H1N1 flu strain to see whether there is a similar co-infection with community-acquired MRSA in some cases.
