Similar to colds, fever, cough, fatigue, loss of appetite and so on.
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.
Prevention:
Get enough sleep, exercise frequently, wash your hands frequently, keep indoor ventilation, and develop good personal hygiene habits.
Treatment:
Tamiflu (oseltamivir) is effective in the early stage of infection.
Information:
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.
Personal protective measures are:
Avoid contact with respiratory patients with flu-like symptoms (fever, cough, runny nose, etc.). ) or pneumonia; Pay attention to personal hygiene and wash your hands often with soap and water, especially after coughing or sneezing; Avoid contact with pigs or go to places with pigs; Avoid going to crowded places; Cover your nose and mouth with a tissue when coughing or sneezing, and then throw the tissue into the trash can; If you have flu-like symptoms (fever, cough, runny nose, etc. In foreign countries, you should seek medical treatment immediately (you should wear a mask when seeking medical treatment) and explain the situation to the local public health institutions and inspection and quarantine departments.
The symptoms of swine flu are similar to colds, and patients may have fever, cough, fatigue and loss of appetite. It is reported that the cases found in the epidemic in the United States in 2009 are mainly characterized by sudden fever, cough, muscle pain and fatigue, and some of them also have symptoms of diarrhea and vomiting; Mexico has also found symptoms such as red eyes, headache and runny nose.
But it is meaningless to just look at the symptoms.
The key depends on whether the epidemic contact history has been to a place where the influenza A epidemic is serious and crowded, and whether it has had close contact with influenza A patients and related personnel. If not, it can be ruled out.
There is no need to worry too much about a landlord. Generally speaking, the symptoms of this disease are very mild.
If you feel sick and have a fever.
Wear a mask and go to the hospital.
Check the throat swab or nose swab. This test is completely free.
Drink plenty of water and pay attention to rest. I believe you will recover soon.
Influenza A H 1N 1 is also called influenza A (H 1N 1), and people are infected with swine flu.
[2] On April 30, 2009, the World Health Organization, the Food and Agriculture Organization of the United Nations and the World Organization for Animal Health announced that they agreed to use influenza A (H 1N 1) to refer to the epidemic at that time, and no longer used the term "swine flu". China's health departments have renamed the people who were originally infected with swine flu as influenza A (H 1N 1). On April 30, 2009, the Ministry of Health of China issued Announcement No.8 of 2009, which clearly listed influenza A (formerly known as human swine flu) as a Class B infectious disease managed by the Law on the Prevention and Control of Infectious Diseases, and took preventive and control measures against Class A infectious diseases. Infectious diseases stipulated in the Law on the Prevention and Control of Infectious Diseases are divided into Class A, Class B and Class C ... Among them, Class A is the most contagious infectious disease with serious consequences, which decreases in turn. Class A infectious diseases include plague and cholera. Class B infectious diseases include more than 20 kinds of infectious atypical pneumonia, AIDS and viral hepatitis. Class C infectious diseases include influenza, hand-foot-mouth disease and so on 10.
Viral characteristics
Influenza A virus (H 1N 1) is influenza A virus, which carries H 1N 1 subtype swine influenza virus strains, including RNA gene fragments of avian influenza, swine influenza and human influenza virus, and has the characteristics of Asian swine influenza virus and African swine influenza virus. Medical experiment showed that the current mainstream antiviral drugs are effective for this strain. Photos from the US Centers for Disease Control and Prevention showed that influenza A virus H 1N 1 was negative.
clinical picture
The incubation period is longer than that of influenza and avian influenza, and the specific time is uncertain for the time being.
The early symptoms of influenza A (H 1N 1) are similar to those of ordinary people, including fever, cough, sore throat, general pain, headache, chills and fatigue. Some of them may also have diarrhea or vomiting, muscle pain or fatigue, and red eyes.
Some patients can progress rapidly, with violent attacks, sudden high fever, body temperature exceeding 39℃, and even severe pneumonia, acute respiratory distress syndrome, pulmonary hemorrhage, pleural effusion, pancytopenia, renal failure, sepsis, shock and Raynaud's syndrome, respiratory failure and multiple organ injury, leading to death. The patient's original underlying disease can also be aggravated.
diagnostic criteria
The "Diagnosis and Treatment Plan for Human Infected with Swine Influenza (2009 Edition)" issued by the Ministry of Health on April 30, 2009 pointed out that the diagnosis of human infected with swine influenza mainly combined with epidemiological history, clinical manifestations and pathogenic examination, and early detection and diagnosis were the key to treatment.
At the same time, the diagnosis and treatment plan also introduces the diagnostic criteria of human swine flu in detail, as follows:
—— Medical observation cases: those who have been to swine flu epidemic areas, or have a close contact history with sick pigs and swine flu patients, and have flu clinical manifestations within 1 week. Those who are listed as medical observation cases will be observed for 7 days (they can be isolated at home or hospital according to their illness).
—— Suspected cases: have been to epidemic areas, or have a close contact history with sick pigs and swine flu patients (or have an unknown epidemiological history), have flu clinical manifestations within 1 week, and have positive respiratory secretions, throat specimens, sputum and serum antibodies or nucleic acids.
-Clinically diagnosed cases: those who are diagnosed as suspected cases and have the same exposure history with them are diagnosed as confirmed cases.
—— Confirmed cases: A specific virus was isolated from respiratory specimens or serum; RT-PCR detection of the above samples showed that there was swine flu virus RNA, which was confirmed by sequencing, or the titer of serum antibody increased by 4 times and 2 times, which could be diagnosed as human infection with swine flu.
symptom
The incubation period of swine flu is generally around 1 to 7 days, and it is generally susceptible, mainly in young adults.
Early symptoms are similar to common flu, including fever, cough, sore throat, body pain, headache, chills and fatigue, and some may also have diarrhea or vomiting, muscle pain or fatigue and red eye.
Some patients can progress rapidly, with violent attacks, sudden high fever, body temperature exceeding 39℃, and even severe pneumonia, acute respiratory distress syndrome, pulmonary hemorrhage, pleural effusion, pancytopenia, renal failure, sepsis, shock and Raynaud's syndrome, respiratory failure and multiple organ injury, leading to death.
The prognosis of human swine flu infection is related to the subtype of virus infected, and most of them have good prognosis; However, the prognosis of H 1N 1 infected people is poor, and the mortality rate is about 6%.
treat cordially
Antiviral drugs such as oseltamivir and Tamiflu should be used as soon as possible, and antibiotics can be used in case of bacterial infection.
Symptoms of lung health poisoning: fever, aversion to cold, sore throat, headache, muscle aches and cough.
Commonly used Chinese patent medicines: Lianhua Qingwen capsule, Yinhuang preparation and Shuanghuanglian oral preparation.
Symptoms of lung and stomach of drug addicts: fever or aversion to cold, nausea, vomiting, abdominal pain and diarrhea, head and body muscle aches.
Commonly used Chinese patent medicines: Gegen Qinlian micro pills, Huoxiang Zhengqi preparation, etc.
Symptoms of toxic qi stagnation: high fever, cough, chest tightness, shortness of breath, irritability, and even delirium.
Reference prescription: Angong Niuhuang Pill, Tanreqing, Xuebijing and Qingkailing can be selected when necessary.
