It has been understood that the virus of a new swine influenza has shape like an elongate bean from the research of Prof. Kawaoka Gihiroshi of University of Tokyo Institute of Medical Science. After U.S. Centers for Disease Control and Prevention (CDC) becomes popular, fragment Otora . of the virus torn off by processing by centrifugal separator before it takes a picture though the dissemination lingua electron micrograph was globular.
It announced by the British science magazine nature dated the 15th (electronic version).

Mr. Kawaoka did not put and elongate shape of about 1/1,000 Miri in length when having taken a picture was had though there was CDC to remove materials other than the virus ..centrifugal separator... The majority of the virus is removed with impurities when putting it on centrifugal separator, and when a remaining fragment reflected in spheroidal, it is Iu.

Various types like globular and elongate shape, etc. are known to the virus of other kinds of influenzas.

Mr. Kawaoka also ascertained the invasion of a new virus to the inside of the body from person's nose and the tunica mucosa of the throat and the Yasui way and the mutations already.

The influenza virus is waited, and invades the inside of the body in the receptor that the proteins of HA on the surface are in person's nose and the tunica mucosa of the throat. HA, the receptor is dealings like the key and the keyseat, etc. , and the infectivity increases exactly in the circle.
When the ball Yasui way had mutated to person's receptor, a part of HA that originates in pig's virus is Iu.
