Nasal washing method: to clean up the warm water of high quality against the non-iodine salt, the concentration of 0.9%. Usually against the 4.5 grams of salt 500 ml warm water. Poured into the nose washing special items such as washing pots in the nose, respectively, on both sides of the nose to flush until the nasal cavity without foreign body up. This method can be repeated several times to keep the nasal secretions of degrees without too much.
Hand-washing method: Apply ordinary soap or a germicidal soap, scrub hands and parts. And then recycle the water flows clean hands.
Prevention Principle
Influenza virus is mainly spread through the air and transmitted. Both the invasion of the main route of transmission points in the nasal cavity. Influenza viruses in the air or contaminated objects and hands when coming into contact with the nose into the nasal cavity.
Under normal circumstances, the nasal cavity itself has a certain degree of detoxification ability to promptly clean up any influenza virus. -Induced factors, in the event of circumstances, such as cold, rain, fatigue, etc., the nasal cavity and detoxification capacity weakened influenza virus a long time remain in the nasal cavity, and the large population invades the human body, thus infected with influenza.
Nasal wash method can help the body in the event triggers the case of influenza virus removal from the nasal cavity, greatly reducing the risk of infection.
[Edit this paragraph] Influenza - Definition and Epidemiology
(A) Overview
Influenza referred to as influenza, is caused by the influenza virus, a common acute respiratory infectious diseases to more common in winter and spring, clinical with high fever, fatigue, headache, body aches and other symptoms of systemic poisoning, it is heavy but the symptoms of mild respiratory Card is characterized by influenza virus prone to mutation, contagious, often cause influenza pandemic. The 20th century, four times the world influenza pandemic in China over the past half a century (1953-present) flu pandemic occurs Dazhong Xiao total of 17 times the size of an influenza pandemic, including two times for a pandemic.
(B) The etiology
Influenza virus belongs to the group are sticky liquid Virus Branch, ball type, diameter 80-120nm, the genome of RNA viruses. Its characteristics are prone to mutation. B, C is divided into three types, of which the most vulnerable to influenza A mutation can be infected and a variety of animals, the major pathogen of human influenza, often cause large epidemics and small pop. Less variation of influenza B virus can infect humans, causing epidemic outbreaks or small. Hepatitis C was more stable, can infect humans, mostly sporadic cases found so far can also be infected pigs. Influenza virus does not heat, 100 ℃ 1 minute or 56 ℃ 30 Fenzhong inactivated, sensitive to commonly used disinfectants (1% formaldehyde, peracetic acid, chlorine disinfectants, etc.) on UV-sensitive, low temperature and drying, vacuum drying or can survive below -20 ℃.
(C) The epidemiology
1, the source of infection: influenza patients and latent infection as the main source of infection. ~ 7 days after onset of an infectious, 2 ~ 3 days in early disease is most contagious. Pigs, cattle, horses and other animals can transmit the flu.
2, mode of transmission: air droplets mainly influenza viruses survive in the air about half an hour daily pollution
3, susceptible populations: the general susceptible to disease after a certain immunity. Between the three types of influenza, influenza is no cross-immunity between different subtypes can be repeated incidence of
4, popular features:
1) Popular features: sudden onset, rapid spread of 2 to 3 weeks and reached the peak of high incidence, prevalence and short, about 6 to 8 weeks, and often spread along the lines of communication.
2) general law; the first cities in rural areas after the first collective units, after the residents dispersed.
Influenza: a common cause of the outbreak of epidemic, and even the world's largest epidemic occurred about 2 ~ 3 years, a small pop a time, according to the world that have occurred in four times a pandemic situation analysis, generally 10 to 15 years is a pandemic.
Was the outbreak of influenza B or a small epidemic, hepatitis C has been circulated mainly.
3) epidemic season; the four seasons can occur, mainly to winter and spring. The South in the summer and autumn can also be seen flu pandemic.
