the latest 2009 flu OUTBREAK!
it's the spread of a new strain of influenza virus.
p/s : i seriously think viruses are so smart, they always come out with new strains.
can u imagine..punye la susah we create antibiotics,the viruses dgn senang hati boleh create another strains yang resistant terhadap antibiotics tersebut.they're so clever ok.
about the latest flu outbreak,it's an apparent reassortment of 4 strains of influenza A virus subtype H1N1.
Analysis at the United States CDC found the 4 component strains as
1 endemic in humans, 1 in birds and 2 in pigs(swine).
so it's called "swine flu" due to it predominantly containing swine strains.hahaha.why not "pig flu"?
other names are H1N1 influenza, 2009 H1N1 flu, Mexican flu, swine-origin flu.
but WHO for Animal Health proposed the name North American Influenza because this new strain and its entirety has not been found in pigs.
so how this new disease spreads?
- direct contact with pigs
- human-to-human! just like common cold
and the symptoms are :
pandemic,for the following reasons :
1. new strain
the virus is a new strain of influenza, from which human populations have not been vaccinated or naturally immunized.
2. wide spread human transmission
the strain was confirmed to have been transmitted between humans. omg that's so easy and scary!
the bird flu(that peaked in 2006) which killed thousands of people pon almost entirely from direct contact between humans and birds.
ape lagi klau human-to-human transmission?
the reported death from the illness have primarily been young,healthy adults!
of course it produces the worst symptoms in the children,elderly and others with weaker immune systems.
4. Lack of Data
many crucial factors are still largely unknown such as transmission rates and patterns (epidermicity) and effectiveness of current influenza treatments combined with the innate unpredectability of influenza strains, means that reliable forcasts can't be made.
however, some scientists believed that this strain was unlikely to cause as many fatalities as earlier pandemics.
just be careful people.
p/s : hahaha..so IKM(public health).. hehe.posting public health saye in about 2 months.waaa...taknak!
