What is the difference between influenza A and common flu?

Influenza A and common flu are all viruses. It's just that the influenza A (H1N1) virus is a new virus with mutations of five swine flu genes, three avian influenza genes and one ** susceptibility gene. The best way to solve it is to boost your immunity. Satisfied.

The incubation period of swine flu is generally about 1 to 7 days, and it is generally susceptible, mainly in young adults. Early symptoms are similar to those of the common flu, including fever, cough, sore throat, body aches, headache, chills and fatigue, and some may also experience diarrhea or vomiting, muscle pain or tiredness, and red eyes. Some patients may progress rapidly, with ferocious onset, sudden high fever, body temperature over 39, and even severe pneumonia, acute respiratory distress syndrome, pulmonary hemorrhage, pleural effusion, pancytopenia, renal failure, sepsis, shock and Reye syndrome, respiratory failure and multi-organ damage, resulting in death.

The prognosis of human infection with swine influenza is related to the subtype of the virus infected, and the prognosis is generally good; The prognosis of patients infected with H1N1 is poor, with a case fatality rate of about 6%. Influenza type, avian influenza, and common influenza Influenza A Influenza Avian Influenza Common Influenza Mode of transmission The virus is very active and can be transmitted from person to pig, pig to person, and from person to person. Human-to-human transmission is mainly mediated by the coughing and sneezing of infected people.

Avian influenza viruses have so far been transmitted only through poultry and not from humans. Human-to-human transmission, airborne droplet transmission is the mainstay, and influenza patients and people with hidden infections are the main sources of infection. It is contagious 1 7 days after the onset of the disease, and the most contagious is 2 3 days after the first 2 3 days of the disease.

Symptoms The most obvious symptom of human infection with swine flu is "the initial appearance of symptoms similar to that of common flu, but the body temperature suddenly exceeds 39 degrees, and the muscle aches and pains are significantly increased, accompanied by symptoms such as dizziness, headache, diarrhea, vomiting, etc., or some of them." The symptoms after infection are mainly manifested as high fever, cough, runny nose, myalgia, etc., most of which are accompanied by severe pneumonia, and in severe cases, death due to heart, kidney and other organ failure. The symptoms of common ** infection are similar to those of people infected with swine flu.

Incubation period Novel swine flu viruses may not show symptoms until 7 days after they have been incubated in humans. The incubation period for human avian influenza is generally 1 3 days, usually within 7 days. The incubation period for influenza is 1-4 days, with an average of 2 days.

Mortality The mortality rate of swine flu is higher than that of general influenza, and there are two main reasons for its high fatality rate: first, the virus is ferocious; Second, the people did not pay attention to the new disease at first, thinking that it was a common cold, and many people took some medicine casually, missing the best treatment period of 72 hours at the beginning of the disease. The human mortality rate from avian influenza is 60%.

Common influenza can be fatal, but the mortality rate is low. Susceptible people The vast majority of patients who die from swine flu are between the ages of 20 and 45 and are young adults. Children under 13 years of age account for a higher proportion of the detected infections and are more severely ill, making them a susceptible group.

The four groups of people most susceptible to influenza are: the elderly, people with chronic diseases such as liver, kidney, and heart, medical staff who are often exposed to influenza people, and children. Prevention and control vaccines All influenza vaccines developed by humans are ineffective against swine flu, but human infection with swine flu is preventable, controllable and curable.

Vaccines against avian influenza are already being developed. Vaccines have been developed to prevent influenza, and most of them are administered once a year from October to mid-November.

In fact, there is no difference in symptoms. The main thing is to see if there is any contact with the disease-like number. Blood tests are required to confirm the diagnosis. It's useless to just look at the symptoms.
