Flu ≠ cold

Recently, there are many people around fever, cough, sore throat and other symptoms, and various hospitals are difficult to line up. Among the circulating influenza viruses, influenza A virus is absolutely dominant. What is Swine Flu? What's the difference between the flu and the common cold?

Influenza is short for influenza, different from the common cold, it refers to an acute respiratory infectious disease caused by influenza virus. Currently circulating seasonal influenza viruses include subtype A H3N2, subtype A H1N1 (pdm09) and Type B Victoria.

The antigenicity of influenza virus is changeable and spreads rapidly. It can cause seasonal epidemic every year, with high incidence in winter and spring. Outbreaks are most likely to occur in places where people gather, such as schools, childcare facilities and nursing homes. People are generally susceptible to influenza virus, and pregnant women, infants, the elderly and patients with chronic diseases and other high-risk groups are more seriously affected by influenza.

It is especially important to distinguish the flu from the common cold. Flu is usually more severe and has more complications.

02 How to identify the flu

01 Route of transmission of influenza

Influenza patients and asymptomatic infected persons are the main sources of seasonal influenza infection. Influenza virus is mainly transmitted through respiratory droplets such as sneezing and coughing of infected people, but also through direct or indirect contact with mucous membranes such as mouth, nose and eyes. In crowded and closed or poorly ventilated rooms, it may also be transmitted by aerosol.

Because the influenza virus is prone to mutation, the influenza strain may change from year to year, resulting in antibodies formed by natural infection or immunization that are difficult to effectively neutralize, so the population is generally susceptible. Children are at higher risk of getting the flu because their immune systems are not fully developed.

02 Symptoms of influenza

Influenza generally manifests as acute onset, fever (some cases may appear high fever, up to 39-40℃), accompanied by chills, chills, headache, muscle and joint pain, extreme fatigue, appetite loss and other systemic symptoms, often pharyngeal pain, cough, nasal congestion, runny nose, poststernal discomfort, facial flushing, conjunctival mild congestion, can also have vomiting, diarrhea and other symptoms.

The common incubation period of influenza virus is 1~4 days, mostly 2 days, and influenza infected people can excrete the virus 1~2 days before the appearance of clinical symptoms, and infected people are infectious from the end of incubation to the acute phase of disease.

Mild flu often behaves like the common cold, but its fever and systemic symptoms are more pronounced. Severe cases may present with viral pneumonia, secondary bacterial pneumonia, acute respiratory distress syndrome, shock, diffuse intravascular coagulation, cardiovascular and nervous system extrapulmonary manifestations and a variety of complications.

03 How to Prevent Flu

Annual influenza vaccination is an effective means of preventing influenza and can significantly reduce the risk of getting the flu and developing serious complications.
