Virtually none seen. This strain of influenza has not been seen in the USA. Cannot say there have been none, but if so, rare. The best way to avoid influenza is through regular yearly vaccination. The CDC tracks the types of flu most commonly seen and those are included in the latest vaccines available.
Culture. A nasal swab and culture diagnoses the specific type on influenza when analyzed.
Overall mortality. Rates in humans is about 60% - so yes, it is dangerous.
Like other flu. Bird flu is usually acquired through close contact with birds and breathing their respiratory secretions. It usually does not spread from person to person, thank god!
Clear cut. Droplets avoid sick people unless you are the doc.
Still around. The virus is still around and has caused disease in the east. See this site for more info. Http://www. Cdc. Gov/flu/avianflu/h7n9-virus. Htm.
Direct contact. Direct contact with infected birds is the only known way to contract this variety of flu.
Pigs. It is my understanding the a pig virus adapted itself to infecting birds.
Southeast Asia. In many areas pigs and ducks and humans are in close proximity in agricultural communities. They can be infected with more than one variety of influenza at the same time and admixture of genetic material occurs dramatically changing the infectivity and virulence of the virus. Under certain circumstances the virus obtains the ability to infect humans and we have a new epidemic.
It is on google. Probably china.
Support. Most of the treatment is supportive, meaning supplemental oxygen if needed, or even mechanical ventilatory support if respiratory failure. It is recommended patients be treated with the anti-influenza drug "tamiflu" if the present with symptoms early enough. Other measures of non specific support may be needed, IV fluids etc. Depending on the severity of illness.
Supportive care. Anti-influenza drugs may be used early in the infection, but generally treatment consists of supportive care and, prevention/treatment of secondary infections.
More deadly. More likely to cause death. Why? Very interesting question that researchers are hard at work trying to answer.
Not entirely known. So far it has infected only persons involved with raising birds, primarily poultry, and does not seem to readily infect other animal species. If the recognized cases are all there are then it has a high fatality rate. The obvious question is can it cross species and create human to human infection? The other risk is that scientists have changed it to infect humans & could be used by terrorists.
Very low this time. But it may come back.
Close contact with b. Close contact with infected birds is the major risk factor. These may be domestic or wild, e.g. Wild geese. Bird flu started in pigs, so theoretically one could get it from pigs too. It rarely spreads from human to human.
Low in this country. The majority of cases of bird flu have been found in asia, africa & europe in recent years. According to the fda, even if you ate the meat or eggs from an infected bird, the disease would not be transmitted if the food is properly cooked. Be safe: get a flu shot. Practice good hand washing technique. Do not eat chicken which is not fully cooked. Do not eat raw or partially cook.
