Difference between corona and flu in terms of signs and symptoms

Corona disease and influenza disease are both viral infections. Viruses are small microbes that can survive by attacking other living cells. These living cells play the role of the host cell for the virus and cause its multiplication.

Corona disease is caused by the SARS-CoV-2 virus. But the flu disease is related to 2 types of viruses called influenza virus A and B. The influenza A virus has several subtypes, all of which can cause the flu.

Both the coronavirus and the flu are respiratory illnesses, but there are many differences between them. These differences can be explored from different directions:

1. The latent period of the disease

The first point that we should mention about the difference between corona and influenza is the latent period of the disease. The number of days between the time the virus enters the body and the appearance of the first symptoms of the disease is called the incubation period. But influenza has a shorter incubation period; So that its symptoms appear after one to four days and on average after 2 days.

Shortness of breath

In addition to the above symptoms, some people may have other symptoms. These symptoms include:

Muscle pain
Headache
Runny or stuffy nose
Sore throat

3. How the symptoms start

Influenza and Corona differ from each other in terms of how the symptoms start. The initial symptoms of corona disease are usually milder and develop gradually. But in most cases, the onset of flu symptoms is sudden.

4. The course of the disease and the severity of its symptoms

Human information about the corona disease is less compared to the flu disease. However, it is known that there are certain differences between them in terms of the course of the disease and the severity of the symptoms.

For example, it is estimated that 20% of confirmed cases of corona infection are severe or critical, and some people may experience exacerbation of respiratory symptoms in the second week of the disease (after an average of eight days).

On the other hand, if the flu is uncomplicated, it usually recovers within three to seven days. In some people, the cough and fatigue may last for 2 weeks or more. Statistics also show that more than 1% of people with this disease are admitted to the hospital.

5. Duration of the disease's contagiousness

It is not known exactly how long people with corona can transmit the disease to others. However, those with symptoms can spread the disease, researchers said. Of course, there may be a possibility of spreading the disease even before the symptoms appear.

A person with the flu can transmit the virus to others one day before the symptoms appear. The spread of the virus continues five to seven days after getting sick.

The difference between corona virus and flu in terms of treatment method

Most people with flu do not need medical treatment. But the doctor may recommend the use of antiviral drugs in some cases. These drugs help the body fight the virus and reduce the duration of symptoms by one to two days. As a result, the disease disappears faster.

Most people with corona disease do not need special treatment. For mild cases, the person should stay at home and observe social distancing. However, antiviral therapy may be recommended for those at risk of developing serious disease. The doctor determines the dangerousness of corona according to the patient's age, health history and duration of symptoms.

Early treatment can reduce the severity of corona symptoms and the risk of hospitalization. In severe cases, patients suffering from corona have breathing problems. Therefore, oxygen therapy or a mechanical ventilation device may be needed.

Vaccination is the most effective way to prevent flu or corona.

The strains of the flu virus that cause disease are constantly changing. Researchers gather each year to predict which strains will cause disease during the upcoming flu season. This will help researchers develop the vaccine needed to fight that strain. For this reason, it is recommended to get the flu vaccine every year.
