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.)

Does the flu require infusion?

Whether to administer intravenous fluids for influenza should be decided based on the severity of the illness, individual constitution, and the duration of the disease. It cannot be determined by the simplicity of the condition alone. Influenza is a contagious respiratory disease caused by infection with influenza or parainfluenza virus. If the immune function is normal and there are no complications, generally one can recover on their own in five to ten days without the need for intravenous fluids. However, if influenza infects a person with a weak constitution and causes complications leading to bacterial infection, resulting in symptoms like breathing difficulties and coughing, intravenous fluid therapy is required.

Routes of influenza transmission

Influenza, also known as the flu, is a disease caused by infection of the upper respiratory tract with the influenza virus. It is characterized mainly by sore throat, cough, and fever, and some patients may also experience nausea, vomiting, and diarrhea. The primary mode of transmission of influenza is through droplets, which occur when an infected person sneezes or coughs, and their secretions, such as nasal discharge, are inhaled by others. Additionally, the virus can be transmitted through the digestive tract and mucous membranes of the skin. If a healthy person comes into contact with the secretions of an infected person, such as through skin contact or orally, they may also be infected. Therefore, it is crucial to isolate from those infected with the flu.

What is type B influenza?

Type B influenza is a type of epidemic influenza characterized by a rapid onset, feeling feverish and chilled. Body temperature usually rises quickly within hours, reaching 39 to 40 degrees Celsius, or even higher. It is accompanied by headache, general body aches, fatigue, and reduced appetite. Its respiratory symptoms are relatively mild, including dry throat, sore throat, dry cough, and possibly diarrhea. Type B influenza is difficult to distinguish from the common cold and typically requires laboratory identification for diagnosis.

How to get a flu vaccine?

Influenza vaccines are mainly produced to prevent epidemic influenza and are currently available in three main types: Type A, B, and C. The target population for influenza vaccine administration primarily includes the elderly, preschool children, and patients with chronic underlying diseases, who are more suitable for vaccination. For children under three years old, the influenza vaccine should be administered twice, as it is administered via muscle injection and cannot be used intravenously. For this age group, the two doses should be spaced at least four weeks apart. For children over three years old and adults, an annual vaccination is sufficient. The optimal time for influenza vaccination is usually in September and October, as influenza tends to outbreak in winter and spring, so vaccinating during these months can greatly prevent influenza.

Is type B influenza contagious?

First, we need to understand what influenza B is. Influenza B, also known as influenza type B, is a type of influenza caused by the influenza B virus. Currently, it is classified as a class C infectious disease, which means it is indeed contagious. The main sources of transmission for influenza B are patients and asymptomatic carriers. Generally, the virus is contagious from one to seven days after onset of the illness, with the highest contagiousness occurring within the first two to three days. Influenza B is a respiratory tract infectious disease, mainly spread through the air and droplets. Most people are susceptible to influenza B.
