Virus: what é, main symptoms and treatment

A virus is any disease that is caused by a virus and that has a short duration, which normally does not exceed 10 days. Its main symptoms include:

  • Diarrhea, fever and vomiting;
  • Sickness and lack of appetite;
  • Muscle pain and belly pain;
  • Headache or behind the eyes;
  • Sneezing, nasal discharge and coughing.

Viruses are more common in babies and children, but can also appear in adults. The symptoms can be very varied, since the virus can be caused by several types of viruses, but it is common for them to happen especially in the respiratory tract or in the intestine, leading to colds and gastroenteritis being often called just the virus.

Thus, although they are also caused by viruses, diseases such as measles, Dengue or Zika, for example, can be more serious and worrying and, therefore, are not usually called just a virus. Check out how to know if it's Dengue, Zika or virus.

When a child has a virus, it is normal for parents and siblings to be affected as well, as it is usually contagious, but in adults the symptoms are milder and last for a shorter time. These symptoms can take up to 5 days to appear, after the child shows the first symptoms, due to the incubation period of most viruses.

For this reason, even if you take the necessary measures to avoid transmission, the virus may have already reached the body, and the most important thing is to always follow tips to avoid viruses, such as washing your hands frequently.

Because the virus is more common in children

The symptoms caused by viruses are more common in babies and children because they still don't have all the resistance that adults have and their immune system is still developing.

So, each time the child comes into contact with a different microorganism, until his body can produce antibodies against the invader, he will show the symptoms of a virus. However, it is unlikely that the child or adult will develop symptoms when coming into contact with the same virus, but as there are many different viruses, when coming into contact with another virus, they may have symptoms, although they may be weaker.

How to confirm if it is a virus

The doctor can identify the virus based on the symptoms alone, especially when the person does not have any other symptoms and when there are other affected people, in the family, at the same school or at work, for example.

It is common to have periods when several children from the same day care center have symptoms of the virus, so if parents know that their child's peers have the virus, there is a possibility that their child is also affected by the virus. this same disease.Therefore, it is important to tell the doctor what symptoms you have and if there are cases of people close to you with the same symptoms.

To make sure it is a virus, the doctor can sometimes also order some specific tests, especially blood or urine tests, for example.

Because doctors don't always order tests

It is not always necessary to do tests to find out if it is a virus because in most cases it is not possible to find out which virus is through a simple blood test. In addition, other classic tests such as X-ray or urinalysis, for example, do not show any changes.

But to make sure that it is not about other diseases, such as rubella, for example, the doctor may request a specific blood test for that disease.

How to cure the virus faster

Treatment for a virus consists mainly of resting and strengthening the body, so that the immune system is able to eliminate the virus more quickly.Thus, the guidelines usually include drinking plenty of water during the day, eating a balanced diet rich in nutrients, as well as resting and avoiding more strenuous activities.

In addition, the doctor may also prescribe some analgesics, such as Paracetamol, for example, to relieve pain and improve comfort during recovery.

During the treatment of the virus, it is advisable to consume light and easily digestible foods, giving preference to fruits, vegetables and cooked lean meats. It is also recommended to avoid very spicy, greasy, gassy or difficult to digest foods.

To avoid dehydration, you should drink at least the same amount of water lost through vomiting and diarrhea.

Warning signs to return to the doctor

It is important to go to the doctor when you have signs and symptoms of dehydration, such as sunken eyes, very dry and dehydrated skin, when diarrhea gets worse or presents with blood, as well as when your cough or shortness of breath gets worse.

If other symptoms such as blemishes on the skin, fever that does not subside with Paracetamol and fainting occur, you should also go to the emergency room.
