What Is the Difference Between Swine Flu and Seasonal Flu?

Swine influenza is an acute, infectious respiratory disease of pigs. It is characterized by sudden onset, cough, dyspnea, fever and rapid prognosis. Swine flu is caused by influenza A virus (influenza A virus) , which usually breaks out between pigs, is highly contagious but usually does not cause death. Autumn and winter are in high frequency, but they can spread throughout the year. Swine influenza is mostly identified as one of the subspecies of influenza C virus (influenza C virus) or influenza A virus. The virus can cause flu outbreaks in swine herds. Humans are rarely infected with swine influenza virus.

The disease has a high incidence,
The pathological changes of swine flu are mainly in the respiratory organs. The mucous membranes of the nose, pharynx, larynx, trachea and bronchus are congested and swollen, and the surface is covered with a thick liquid. The small bronchi and bronchioles are filled with foam-like exudate. Chest cavity,
According to the epidemiological history, incidence, clinical symptoms and pathological changes, the pig can be preliminarily diagnosed as having influenza-associated haemophilus parasuis.
Two of the three viruses that infected human influenza also infected pigs. Among them, influenza A virus is commonly found in swine herds, while type C is rare, and there have been no reports of pigs infected with influenza B virus. In influenza A and C viruses, large differences are found between pig and human disease species, although due to
In order to avoid zoonotic disease, breeders and people who come into direct contact with pigs should take effective protective measures and pay attention to personal hygiene; wash hands often with soap or water to avoid contact with pigs, and avoid flu-like symptoms (fever, cough). , Runny nose, etc.) or respiratory patients such as pneumonia; especially after coughing or sneezing; avoid touching live pigs or places where there are pigs; avoid going to crowded places; cover your mouth and nose with a tissue when coughing or sneezing, and then Throw paper towels in the trash. All pigs with unknown causes of death were burned and buried and then disinfected. If a person is accidentally infected with the swine flu virus, it should be reported immediately by the higher-level health authority, and those who catch the disease should be observed for 7 days of medical isolation.
1. Bedding and changing hay frequently, and disinfect the pighouse with 5% caustic soda regularly.
2, pay close attention to weather changes, once the temperature is lowered, timely heating and insulation.
3. Prevent susceptible pigs from coming into contact with infected animals. Humans should not come into contact with swine when they develop influenza A.
4. Swine flu adjuvant inactivated vaccine can be used to inoculate pigs twice in a row, and the immunization period can reach 8 months. [1]
Level 1 alert: In nature, influenza viruses, especially birds, are transmitted by animals, but the virus has not been passed from animal to animal or transmitted to humans.
Level 2 alert: Influenza viruses from animals spread to domestic or wild animals and begin to threaten humans.
Level 3 alert: The influenza virus carried by animals has infected a small number of people, but it is only a limited infection and there is no sign of the possibility of large-scale transmission. Bird flu belongs to the third level of alert.
Level 4 alert: It is characterized by human-to-human infections caused by animal-to-human transmission that has been verified and erupted at the community level, and its infection capacity is sufficient to have a significant impact on society. Any such situation must be assessed jointly with WHO.
Level 5 alert: In at least two countries or regions, humans are transmitting influenza viruses to each other. This shows that the large-scale spread of the virus is imminent.
Level 6 alert: large-scale animal flu outbreaks begin worldwide
Symptoms of swine flu infection in humans are similar to those of a cold. Patients develop fever, cough, fatigue, and loss of appetite. In terms of prevention, it is not necessary to get together to get the human flu vaccine at this stage, because the prevention of seasonal flu vaccines has no effect on the prevention of swine flu. The correct way is to develop good personal hygiene habits, get enough sleep, exercise, reduce stress, and nutrition; wash your hands frequently, especially after touching public goods before touching your eyes, nose, and mouth; sneezing Cover your mouth and nose with a tissue when coughing and coughing; keep the room ventilated and so on.
Causes of the disease's transmission in the population Etiology: Respiratory infectious diseases caused by the swine flu virus, and human-like infections will cause flu-like symptoms.

Swine influenza symptoms

Similar to colds, fever, cough, fatigue, loss of appetite, etc.
The most obvious symptom of swine flu infection in humans is "the first symptoms that resemble ordinary flu, but the body temperature suddenly exceeded 39 degrees, the muscle soreness significantly increased, accompanied by dizziness, headache, diarrhea, vomiting and some other symptoms.

Swine influenza spread

Fast transmission: The human body does not have natural antibodies to the new variant virus.
Mode of transmission: Sneezing, coughing and physical contact may cause the new swine flu virus to spread from person to person.
Human infection with swine flu: It may be through contact with infected pigs or the environment infected with the swine flu virus, or through contact with people infected with the swine flu virus. It can be transmitted from human to pig, from pig to human, or from person to person. Human-to-human transmission is mainly mediated by cough and sneeze of infected persons. Symptoms of swine flu infection in humans are similar to those of ordinary human flu, including fever, cough, sore throat, physical pain, headache, chills, and fatigue. Some may also experience diarrhea and vomiting. In severe cases, pneumonia and respiratory failure may occur. even death.

Swine flu susceptible crowd

The majority of people diagnosed with the swine flu virus are between the ages of 25 and 45. The majority of those infected are young adults, not the elderly and children.

Swine influenza incubation period

The new swine flu virus may show symptoms after 7 days of incubation in humans. The death rate of swine flu is 6.77%, which is higher than that of general influenza. There are two main reasons for its high lethality: one is that the virus is fierce; the other is that people do not pay attention to new diseases at first, and think it is a common cold. Many people themselves Take some medicine casually, missed the best treatment period of 72 hours at the beginning of the onset.

Swine influenza prevention

Get plenty of sleep, exercise, wash your hands, and keep indoors ventilated, and develop good personal hygiene habits.
Personal protective measures include: avoid contact with respiratory-like symptoms (fever, cough, runny nose, etc.) or respiratory patients such as pneumonia; pay attention to personal hygiene, wash hands with soap and water, especially after coughing or sneezing; avoid contact with live pigs or go to Places for pigs; avoid crowded places; cover your nose and mouth with a tissue when coughing or sneezing, and then throw the tissue into a trash can; if flu-like symptoms (fever, cough, runny, etc.) occur overseas, you should seek medical treatment immediately (Wear a mask when visiting a doctor) and explain to the local public health agency and inspection and quarantine department.

Swine influenza treatment

All influenza vaccines that have been developed by humans are not effective against swine flu, but human infection with swine flu is preventable, controllable, and curable. Duffy is effective early in the infection.
1. Isolate the patient from the rest of the family and maintain a distance of at least 1 meter;
2. Cover the mouth and nose with masks and other covers when caring for patients;
3. Whether it is purchased from a store or a home-made covering, it should be discarded after each use or thoroughly cleaned by an appropriate method;
4. After each contact with the patient, hands should be thoroughly washed with soap; the space where the patient lives should be kept ventilated, and the doors and windows are often opened to maintain ventilation;
5. If there is already a case of H1N1 influenza in your country, you should deal with family members who show flu symptoms according to the requirements of the national or local health department.
