this wave of winter flu epidemic has triggered a wave of public opinion. Recently, some media even said & other; This year’s influenza b comparable SARS” .
, a CDC experts on January 6 afternoon surging news (www.thepaper.cn) reporter interview, stressed that that is not available, bo person eyeball outside were more likely to cause social panic.
he emphasized, from the viral pathogens, the propagation force and pathogenicity, influenza b virus was different with the SARS virus. Among them, the flu is a common seasonal flu virus infection, although the cross infection transmission speed, but the fatality rate is low, can also through the vaccine to prevent, the SARS virus can direct violation viscera cause death.
virus is different, the propagation force healing force difference
seasonal influenza viruses are divided into a and B, in which a (divided into 3 type a type 1 a (H1N1) and a (H3N2), hepatitis B is divided into B/Yamagata (BY)) and B/Victoria (BV).

& other; The main popular b influenza and SARS pathogen, the propagation force and lethal force is different. Throughout the &; A CDC experts say that SARS is caused BY the SARS virus, and the current influenza mainly hepatitis b caused BY virus, two kinds of different pathogens.
second, two kinds of the spread of the virus and pathogenic forces vary greatly. Experts say the SARS virus pathogenic strong, infection rates are around 10%, after will direct violation organs lead to death, and influenza b virus transmission speed, but the fatality rate is low, far from achieving the severity of the SARS virus caused to human body.
& other; B virus infection after the onset of symptoms, severity, and even lighter than swine flu and the common symptoms such as fever, upper respiratory tract infection, the virus caused body damage, mostly concentrated in the resistance to poor elderly and young children, can appear the symptom such as pneumonia.

as to why it’s important to wash your hands, experts say, there are two kinds of influenza transmission way, it is or they are transmitted through the air, the droplets spread in the range of 2 to 3 meters, to curb the droplet transmission, both patients and healthy people, all have to wear a mask; Second, the flu will spread through contact, & other; Ordinary people are often sneeze accustomed to use hands to cover your mouth and nose, reoccupy hand to contact with other objects, shake hands or remove virus, are vulnerable to the spread of the virus, so the hand washing is also a effective way to curb the spread of the virus.
