Flu is a continuous disease with lower intrathoracic infection associated with diarrhea. Flu is transmitted through droplet infection from an infected person or through contaminated objects. The period of infection is 4 to 9 days. Antihistamines and decongestants are used to treat the flu. At this time, doctors recommend full bed rest and fluid intake. Nowadays, vaccines are also available to treat the flu.

Influenza is commonly referred to as the flu, which is itself caused by infection with the influenza virus. It is so deadly that sometimes it even causes death. The viruses are transmitted through the inhalation of droplets from an infected person or through contaminated objects (droplet infection). The incubation period of the infection is 1-4 days.

What is Flu?

Flu is a continuous disease with lower intrathoracic infection associated with diarrhea. Flu is transmitted through droplet infection from an infected person or through contaminated objects. The period for this infection is 4 to 9 days.

The symptoms are high fever, chills, headache, dizziness, sore throat, running nose, nausea, vomiting, diarrhea, and trouble breathing. Paracetamol and Metrogyl are given to reduce fever and diarrhea. At this time, doctors recommend full bed rest and fluid intake. Nowadays, vaccines are also available to treat the flu.

There are a few things to keep in mind when treating the flu. Mainly in this condition, the doctor recommends rest. It is also advised to consume fluids so the body can fight and survive the infection. In such a situation, taking paracetamol improves its symptoms. But avoid taking NSAIDs. To prevent the flu, a vaccine is also given annually, which limits the problems caused by it and prevents it.

T cells are present in our bodies. When any virus invades our body, then these cells recognize them. And thus, it starts spreading in the throat and lungs to fight them. This causes swelling in the area, which gives a feeling of pain. After some time, these cells kill and eliminate those viruses from the lungs. This is why the flu hurts so much.

What is Influenza?

Influenza is an upper respiratory tract disease caused by viral infections. Influenza is an upper airway infection caused by Influenza Virus. The infected area is the nose and respiratory passage. The viruses are transmitted through the inhalation of droplets from an infected person or through contaminated objects (droplet infection). The incubation period of the infection is 1-4 days.  The general symptoms are sore throat, headache, fever, sneezing, pain all over the body, and nasal discharge.

This fatigue can last up to three weeks. Symptoms of its worsening are known when the fever starts increasing rapidly in the body and difficulty in breathing is felt. In this way, the body becomes weak.

Influenza is fatal for people over 65 years of age. Their body is unable to protect themselves from this infection. This time is considered difficult for them. If influenza occurs in older people, they can also become a victim of pneumonia, leading to their death.
