Symptoms of swine flu are similar to colds, such as fever, runny nose, stuffy nose, cough, sore throat, headache, general malaise and loss of appetite. Some patients may have digestive tract symptoms, such as nausea, abdominal pain, diarrhea and watery stools. In terms of prevention, there is no need to get together for flu vaccines at this stage, because seasonal flu vaccines have no effect on preventing swine flu. The correct way is to develop good personal hygiene habits, correct health preservation methods, adequate sleep, diligent exercise, reduce stress, adequate nutrition, and diet based on strengthening the body and eliminating dampness; Wash your hands frequently, especially after touching public goods, and before touching your eyes, nose and mouth; Cover your nose and mouth with paper towels when sneezing or coughing; Keep indoor ventilation, etc.

The main causes of this disease:

The incidence of the disease is high, the incubation period is 2 ~ 7 days, and the course of the disease is about 1 week. At the beginning of the disease, sick pigs suddenly have symptoms such as fever, listlessness, loss of appetite or abandonment, often lying together, unwilling to move, having difficulty breathing, coughing violently, and mucus flowing out of eyes and nose. If the treatment is not timely in the onset period, it is easy to be complicated with bronchitis, pneumonia and pleurisy, which will increase the mortality rate of people.

On April 23, 2009, an official of the US Centers for Disease Control and Prevention pointed out that the prevalent swine flu virus was influenza A virus, which carried H 1N 1 subtype swine flu virus, including DNA gene fragments of three influenza viruses, namely avian influenza, swine flu and human influenza, and had the characteristics of Asian swine flu and African swine flu virus. Western medicine experiments show that the current mainstream antiviral drugs are effective for this strain.

People in North America and Europe like to eat barbecue. When pork or its products are roasted, they are mostly 7-8 mature, and their bacteria or viruses are not completely killed, which is easy to cause personnel infection. Moreover, eating half-cooked food is not good for the stomach, and it is easy to be depressed and wet. Qi deficiency and dampness stagnation are the main causes of the disease.

In the eyes of Chinese medicine, this disease is obviously a cold with dampness. It's just a disease, and it's in the fur and can be cured with drugs. After a long illness, you can't cure it if you immerse yourself in it. Is a doctor who can't even cure skin diseases a real doctor? Doctors who can't cure diseases should call veterinarians. Veterinarians are not necessarily responsible for treating the dead. It's easy to do! Poor pig farmers .....

Rapid spread:

The human body has no natural antibody to the new mutant virus.

Mode of transmission:

Sneezing, coughing and physical contact can all lead to the spread of the new swine flu virus among people.

Susceptible population:

Most of the people who died of swine flu virus were between the ages of 25 and 45, and the patients infected with the virus were mainly young adults, not the elderly and children.

Ways of human infection with swine flu:

It may be through contact with infected pigs or the environment infected with swine flu virus, or through contact with people infected with swine flu virus. The symptoms of human swine flu infection are similar to those of ordinary people, including fever, cough, sore throat, general pain, headache, chills and fatigue. Some people will have diarrhea and vomiting, and in severe cases, they will have pneumonia, respiratory failure and even death.

Prevention and treatment methods: At this stage, there is no need to get together to hit people with flu vaccines, because seasonal flu vaccines have no effect on preventing swine flu. The preventive method of traditional Chinese medicine should be based on wet method to adjust the balance of yin and yang in order to achieve the purpose of prevention and treatment.

What's the difference between the new swine flu and the previous avian flu and the common flu?

Let's learn about the relevant knowledge.

First of all, the swine flu virus is very active in the transmission route, which can be transmitted from people to pigs, from pigs to people, and from people to people. The transmission between people is mainly mediated by coughing and sneezing of infected people.

So far, bird flu virus can only spread from birds to people, but not from people to people.

Common influenza viruses can spread from person to person, mainly through air droplets, and influenza patients and recessive infected people are the main sources of infection. It is contagious 1-7 days after onset, and it is the most contagious in the early 2-3 days.

In terms of symptoms, the symptoms caused by the three influenza viruses are similar. At first, human infected with swine flu appeared similar to common flu symptoms, but the body temperature suddenly exceeded 39 degrees, muscle soreness increased significantly, accompanied by dizziness, headache, diarrhea, vomiting and other symptoms.

The main symptoms of human infection with avian influenza virus are high fever, cough, runny nose and myalgia. Most of them are accompanied by severe pneumonia, and severe heart and kidney failure leads to death.

Compared with the common influenza, the mortality of new swine influenza virus and avian influenza virus that appeared in recent years is much higher. So far, the death rate of swine flu infection in the world has reached about 6.4%. The mortality rate of human infection with avian influenza is as high as 60%.

In addition, most patients infected with the new swine flu virus are young people, and the vast majority are between the ages of 20 and 45. Among the cases of human avian influenza infection, 13 children account for a high proportion, and their illness is serious, so they belong to susceptible population. The people who are prone to the common flu are the elderly, children, patients with chronic diseases and medical staff who often contact the flu.

According to reports, at present, the common influenza vaccine has been promoted and used, and the avian influenza vaccine is being developed. The recent outbreak of swine flu has not yet developed an effective vaccine. Therefore, experts suggest that in the absence of effective preventive vaccines, people should consciously strengthen personal hygiene to prevent infection with swine flu virus.

Similar to the general flu, upper respiratory tract infections such as cough and expectoration are more common, and feces are also possible. It can be transmitted from person to pig, from pig to person and from person to person.

Swine flu is easier to spread.

At present, the swine flu outbreak in Mexico has ravaged the world, and many countries have taken various measures to stop its spread. More than 150 people died of swine flu in Mexico, and nearly 2000 people were suspected cases. In the United States, the number of confirmed cases of swine flu has risen to 65, and confirmed cases have also appeared in Europe, New Zealand, Israel and Canada. Why is the epidemic in Mexico particularly serious? The US "Time" weekly website reported on the 28th.

The epidemic situation in Mexico is serious.

At present, there are no confirmed deaths in other places except Mexico, and not many people are admitted to hospital for treatment. Richard Besser, executive director of the US Centers for Disease Control, said that in the United States and other countries, the situation is still relatively mild.

However, Mexico is a different picture, and the severity of its influenza epidemic far exceeds that of other countries and regions. As more and more blood samples of Mexican patients are tested in the laboratory, the number of suspected cases and deaths may rise. At present, there are not many laboratories that can detect swine flu in Mexico, which will also lag the number of confirmed cases.

In order to prevent the spread of the virus, all restaurants, bars, cinemas, stadiums and some government office buildings in the capital city of Mexico City were closed, all schools were closed until May 6, and all public activities were cancelled. The government provides masks to the public free of charge, airlines also require all passengers to wear masks during security inspection, and airports in many countries have taken isolation measures for passengers from Mexico. Cuba delayed all flights to Mexico.

The route of transmission may be the main reason.

Why does the swine flu virus have such a great impact on Mexico? "This is a problem worthy of study and attention, but we still don't know why these differences occur," said Keiji fukuda, temporary assistant director-general of the World Health Organization in charge of health, safety and environment.

We must first find the source of the virus. Earlier, some epidemiologists thought that the culprit of swine flu epidemic might come from a large pig farm in the Gulf city of Veracruz, Mexico. Influenza-like cases began to appear like mushrooms after rain in early April, and the first case was not diagnosed until April 13. However, even if the virus is swine flu virus (A/H 1N 1), researchers are not sure that A/H 1N 1 virus is produced in pigs. There is no evidence that pigs have swine flu, neither in the United States nor in Mexico. Experts also stressed that eating pork will not get sick.

Swine flu virus actually comes from wild birds and can spread infectious diseases to poultry and humans (similar to the spread of H5N 1 avian influenza virus in 2003), and then spread to pigs. Pigs can be infected by viruses from birds, pigs and humans. Pigs also provide an environment for viruses to exchange genes and create new virus strains. This process is called gene recombination, which is the case with A/H 1N 1 swine flu virus.

A/H 1N 1 virus contains influenza viruses from birds, pigs and humans. Peter Daszak, chairman of the Wildlife Conservation Foundation and an emerging disease expert, said that it is easy to happen in places where pig farms, people, birds and poultry live together, such as pig farms in Veracruz.

The mode of transmission of swine flu is also different from that of avian influenza and SARS. Bird flu will not spread from person to person; SARS can be transmitted through saliva; Swine flu virus can spread from person to person. At present, there is no effective vaccine.

In the six years since the H5N 1 avian influenza virus first appeared, health officials often focused their attention on Asia. Dazak pointed out that Mexico, where pigs and poultry live together, has been ignored by many scientists.

Because swine flu virus seems to survive well in the population, control is no longer a good choice, and slowing down the spread may be a better way to deal with the virus.

Some people think that the difference in the prevalence of influenza virus between Mexico and the United States may also indicate that the viruses in the two countries are different. Keiji fukuda said that the researchers sequenced the Mexican and American swine flu viruses and found no genetic differences. Even if there are genetic differences, it doesn't mean anything. Scientists still don't know what genes affect swine flu virus.

The danger of the virus has been weakened in the spread.

Some experts also believe that in Mexico, this virus appeared a few weeks earlier than in the United States. A/H 1N 1 virus, which may have started in Mexico, was very fierce and deadly at first, but when these viruses spread from Mexico to other countries, their danger has been greatly weakened in the process of evolution. This situation often occurs in the process of evolution, because if the virus is too lethal and kills the host before finding other transmission channels, then the virus itself cannot survive.

Stephen Krebke, chief scientist and virologist of ViraCor Laboratory, said: "In an epidemic, viruses will find a balance between causing fatal deaths and their ability to spread." Perhaps in interpersonal transmission, A/H 1N 1 virus weakened its lethality, and when it became easier to spread, it also reduced its danger.

However, the World Health Organization said that so far, the performance of the virus in the transmission chain is quite stable, and it is impossible for the virus to change much. However, the current weakness of the virus does not guarantee that it will not become more deadly in the future, just like the influenza outbreak in 19 18, which killed at least 50 million people around the world.

In addition, with the end of the flu season in the northern hemisphere, the power of influenza virus in the United States will gradually weaken. However, influenza virus strains may continue to spread in the southern hemisphere during the flu season and then return to the northern hemisphere in the following winter.

Any conclusion is premature. As the saying goes, know yourself and know yourself. At present, we know too little about swine flu virus, so it is doomed to be a difficult and protracted tug-of-war. Besser pointed out that the fight against swine flu virus is a marathon, not a 100-meter sprint, and we haven't started yet.

Thicken the healthy protective wall ...

Swine flu is an acute respiratory infection of pigs or people caused by influenza A virus. The disease often occurs in pigs and rarely leads to the death of pigs (the death rate of pigs is 1-4%). Humans are rarely infected with swine flu virus, but some cases of swine flu have been found, most of which are people who have had direct contact with sick pigs. In March 2009, people were infected with swine flu virus in Mexico and the United States, which was influenza A virus, subtype H 1N 1 swine flu virus strain. This strain contains gene fragments of three influenza viruses: swine flu, avian flu and human flu. This is a new swine flu virus, which can infect people. The early clinical symptoms of human infection with swine flu are similar to influenza, including fever, cough, fatigue, loss of appetite and diarrhea or vomiting. The disease will develop rapidly, with sudden high fever and pneumonia. In severe cases, respiratory failure and multiple organ damage will occur, leading to death.

(1) source of infection.

Mainly sick pigs and pigs carrying the virus, people infected with swine flu virus have also been confirmed to spread the virus. Animals infected with this virus can spread.

(2) means of communication.

It is mainly transmitted through respiratory tract, but also through contact with infected pigs or their feces, surrounding polluted environment or aerosol. Some strains, such as H 1N 1, can spread from person to person in a way similar to influenza, usually through coughing or sneezing of infected people.

(3) susceptible population.

Generally susceptible. Most patients are between the ages of 25 and 45. At present, it is mainly young and middle-aged, paying attention to the elderly and children.

(4) high-risk groups.

People engaged in pig industry, people who have been to pig breeding, sales and slaughterhouses within a week before onset/kloc-0, and laboratory staff who are exposed to materials infected with swine flu virus are high-risk groups.

People infected with swine flu mostly occur in winter and spring, and pigs infected with swine flu mostly occur in summer and autumn.
