The diagnosis of influenza is made by a general practitioner by assessing the symptoms present and the person’s health history.

In addition, to confirm the diagnosis, doctors may order laboratory tests such as rapid molecular antigen analysis, PCR testing, and immunofluorescence testing to identify the antigen and virus.

How does transmission occur?

Influenza can be spread directly through respiratory secretions, sneezing, coughing, or talking from an infected person. These droplets contain viruses, and infection occurs when they come into contact with respiratory mucosa, such as another person’s mouth, nose, or eyes.

Mild cases of the flu in healthy people usually improve within two weeks without the need for antiviral drugs. In these cases, some homemade syrups with anti-inflammatory and expectorant properties, such as ginger or beet syrup, can also help relieve symptoms.
