What are the differences between flu and cold?

“Am I a cold? Or do I get the flu?” This is a question that most people often have.

Because cold and flu have many similar symptoms, it is not easy to judge directly from the patient’s symptom.

But the biggest difference between the flu and the common cold is that the symptoms of flu usually appear suddenly, and most patients will have symptoms such as high fever, headache, muscle aches, and extreme fatigue.

What is the flu?

Influenza, or flu for short, is an infectious disease caused by the influenza virus.

The symptoms of flu, the most common symptoms are high fever, runny nose, sore throat, muscle aches, headache, cough, and tiredness.

Patients usually develop symptoms 2 days after exposure to the virus. Symptoms usually heal within a week to two weeks, but cough symptoms may last for more than two weeks.

Possible complications of influenza include viral pneumonia, secondary bacterial pneumonia, sinus infection, and other diseases that worsen (such as asthma or heart failure).

Three main types of flu

Influenza A

It causes the most severe symptoms and high antigenic variability. Large mutations may occur to produce new virus strains, which may easily cause pandemics worldwide. Physical discomfort is more intense.

Influenza B

It causes milder symptoms than influenza A, and the variability of antigens is more stable, mainly due to regional epidemics. Diarrhea and muscle aches are more intense.

Influenza C

Symptoms are more mild or even asymptomatic, and influenza is less likely to develop.

The causative agent of colds may be as many as hundreds of different viruses, while influenza is an acute respiratory infection caused by influenza viruses.

The flu is prone to very obvious symptoms such as headache and fever, physical fatigue, and muscle aches.

The symptoms of flu are more sudden, and the time it takes for the flu to fully heal is longer than that of the common cold. It takes about 1-2 weeks or more than 2 weeks to fully recover. If the flu is not treated in time, it may cause a variety of complications and even death.

Once infected with the flu, it is inevitable for a few days of painful course, and even face the risk of severe flu.

Therefore, the prevention and treatment of influenza are particularly important.

The reason why the influenza virus can continue to pose a threat to humans is mainly that the virus will produce mutations, which is not so easy to prevent comprehensively.

Even people who have been infected with the flu may re-infect the newly mutated flu virus without immunity.

And when most people have no immunity, a national pandemic will occur.

Some patients may judge the symptoms by themselves, or take antibiotics, but antibiotics are not helpful for the treatment of influenza.

Because the main cause of influenza is a virus, so if symptoms of suspected influenza appear, please go to the doctor for treatment.

Why do you get flu? Which ethnic groups should pay special attention to?

The main way of infection of flu is through droplet infection: coughing and sneezing are both ways of spreading. The virus usually enters the body through the mucous membranes of the mouth, nose, or eyes.

Special attention must be paid to the fact that influenza can infect anyone, especially school-age children, and the elderly are the second.

However, serious complications leading to death often occur in the elderly, infirm, or infants.

Once the flu season is high, especially younger babies and young children are more likely to cause serious complications and make parents very uneasy.

When children are infected with the flu, they sometimes have different symptoms than adults.

For example, newborns and babies are prone to a high fever of more than 39.5°C, and young children occasionally experience vomiting, diarrhea, stomach pain, ear pain, etc., and many children suffer from muscle soreness in some parts. To an inability to act.

Therefore, parents can make a preliminary judgment from these conditions. If a child has a flu infection, they should seek medical treatment as soon as possible.

They should never be taken lightly or give their children medication.
