Do you suffer from a runny nose? Do you have a fever? How do you know if you have a cold, flu, or emerging coronavirus (SARS Cove 2) that causes Covid-19 disease? How does the virus infiltrate the lungs? Our answer.

We start with a cold, cold, or cold, and are caused by more than two hundred types of viruses, including the rhinovirus and some coronavirus (the same family of the emerging corona virus). Symptoms may include:

1- A slight infection in the upper respiratory tract.

2- Nasal obstruction.

3- Sore throat.

4- Runny nose.

5- Sneezing.

6- The symptoms are usually mild.

flu

A disease caused by a group of different influenza viruses, it is very contagious and spreads easily to other people, and is likely to be transmitted to another person for the first five days of infection.

Symptoms may include:

1- Fever.

2- Headache.

3- Fatigue and feeling pain in the body.

4- Sometimes runny nose, sneezing and sore throat.

5- Symptoms of the flu may be more serious than those associated with the common cold.

6- Some people may experience anorexia, diarrhea, or abdominal pain.

7- In more serious cases, influenza can also cause pneumonia.

Covid-19

It is caused by the emerging coronavirus, SARS Cove 2, and symptoms may include:

1- Coughing.

2- Shortness of breath.

3- Fever.

4- Losing or regressing the sense of smell.

5- Losing or regressing the sense of taste.

6- It may develop into pneumonia.

7- In some cases, the patient suffers from kidney failure, and in more serious cases the virus leads to death.

7- In most patients, the symptoms of a common cold usually peak during the first two to three days of infection, while the effects of the emerging coronavirus appear two to 14 days after infection.

Loss of smell or taste may be an important sign, according to data that a large number of Corona patients in South Korea, China and Italy have recorded a loss or decline of smell capacity.

Although colds and viruses in general - not only the emerging corona virus - may cause nasal congestion, which can lead to a loss of ability to smell, this symptom has been widely recorded and observed with patients of the emerging corona virus.

It should be noted that a percentage of people with corona may not show symptoms or have mild symptoms, so when in doubt about infection, you should contact the hotline designated in your country for Corona patients.

The last travel trip to a place where the cases of corona, or contact with patients with the disease, may indicate a greater probability of contracting the coronavirus.

Does Corona virus reach the lungs through the nose or throat?

The question arises: What path does the virus take to infiltrate the body? Does it use throat tissue or nasal mucosa as a body entrance?

This was the focus of study for a team from various universities in North Carolina. The scientific team succeeded in tracking the path of entry of the Corona virus into the body, as it was found that it infects the cells of the mucous membrane in the nose first, and from there it makes its way to the lower part of the respiratory system, according to the transfer of the German "Derstandard" website.

The current evidence to monitor the disease indicates that the methods of spreading are through droplets of droplets, especially when people cough, and the infection is transmitted by droplets entering the eyes, nose or mouth directly or through contaminated surfaces.

According to the study published in the specialized scientific journal "Seel", the researchers examined different types of human cells from the nasal mucosa, pharynx and bronchi.

The relatively high rate of infection in the nasal mucosa prompted researchers to conclude that the virus begins its path from the cells of the nasal cavity, and from there it reaches deeper areas of the lungs through the body fluids.
