Influenza is primarily a disease caused by an infection of the upper respiratory tract with the influenza virus. It is a contagious disease that can spread among people, leading to an outbreak. Although influenza is a frightening illness, it is a viral infection characterized by being self-limiting, meaning that whether or not medication is used, the patient's condition can improve on its own. Typically, the course of influenza can improve on its own within about 7 to 10 days. At this time, it is sufficient to use medications that reduce fever, relieve pain, or treat nasal congestion and coughing, since patients generally recover on their own after about 7 days, and medication is only needed to alleviate symptoms. (Please use medication under the guidance of a doctor.)

How to prevent the flu

Influenza, also called flu, is caused by influenza viruses, which are categorized into three types: A, B, and C. After infecting a human, symptoms exhibited by a patient include fever, sore throat, cough, and phlegm, which characterizes the disease called influenza. This disease is classified as a Class B infectious disease in China and has a certain level of contagiousness among populations. It can also be transmitted to humans from certain animals, such as birds and pigs. In the prevention of influenza, the first step is to isolate the patient and the source of infection. The patient must not be contacted. Second, it is necessary to cut off the transmission routes, for example, industries related to the slaughter of poultry and pork should be avoided. Third, it is important to boost resistance and nutrition. Fourth, opening windows to ventilate and avoid overly polluted air can also help in preventing influenza.

Do you need to isolate for the flu?

Influenza can be classified into three types based on the surface membrane proteins and nucleocapsids: type A, type B, and type C. Type A influenza usually causes major outbreaks in populations. Due to frequent genotypic changes in type A influenza, the general population often lacks immunity against it. Generally, influenza is a legally designated class B infectious disease in the country, and it can be transmitted to normal or healthy individuals through droplets, sneezing, or aerosols. Therefore, if an outbreak occurs, isolation measures should be taken, people should avoid crowded public places as much as possible, and maintain ventilation by keeping windows open, to prevent transmission from infected patients or certain animals.

Can the flu cause diarrhea?

Influenza can cause diarrhea, but this is a minority occurrence. Influenza is a disease that appears after the respiratory system of a human body gets infected with the influenza virus. After infecting the human body, influenza primarily manifests symptoms like coughing, sore throat, and fever. However, some patients may develop gastrointestinal symptoms such as diarrhea, nausea, and vomiting after being infected with influenza. This situation is related to viral infection, not the commonly thought stomach flu or food poisoning. Some patients may also experience joint pain and a decrease in appetite. If a patient experiences diarrhea accompanied by respiratory infection symptoms and has tested positive for influenza antibodies, it is necessary to promptly use antiviral drugs for influenza. However, many doctors who do not have such experience in diagnosing influenza might mistake the nausea and diarrhea caused by influenza for gastroenteritis, leading to a delay in proper treatment. Therefore, if one has respiratory symptoms accompanied by gastrointestinal symptoms, the possibility of influenza should be considered.

Can the flu cause recurring fever?

Influenza can cause recurrent fever as a symptom. Epidemic influenza, also caused by influenza or parainfluenza virus infection, is a type of acute respiratory infectious disease. The presence of the virus in the body can stimulate the body's temperature regulation center, which may cause recurrent episodes of fever, typically lasting about three to five days, and the fever should not persist beyond seven days, so there is no need for excessive worry. It is advised to drink plenty of water, rest adequately, and take appropriate antipyretic medication to manage the fever when it occurs. Additionally, antiviral medications like Qingkailing or antiviral oral solutions can be used for antiviral treatment. (Specific medications should be taken under the guidance of a physician.)
