Learn about the most common flu myths to ignore and the scientific facts associated with them to avoid misleading information and protect your health and your family’s wellbeing.

Correcting Common Flu Misconceptions

Many misconceptions about this illness are widespread, most notably the belief that contracting it is not serious. In reality, it is a contagious disease that can lead to severe health complications if neglected, with risks increasing particularly for children, the elderly, and those with chronic conditions.

There are also several flu misconceptions regarding the causes of the disease and how it spreads, including:

Weather effects: Some believe that cold air causes the illness directly, but the truth is that cold itself is not the cause; rather, environmental factors help viruses multiply more densely when temperatures drop.
Timing of infection: Infection is not limited to winter; the virus can also be transmitted during the summer.
Contagion window: A common belief is that the disease is only transmitted after symptoms appear, whereas infected individuals can spread it to others one or two days before signs emerge, and this continues for up to 7 days after symptoms begin.

Infection Methods and Treatment of Flu Myths to Ignore

The virus is transmitted through the air via droplets from an infected person’s saliva, or by touching contaminated surfaces where the virus can survive for up to 8 hours, subsequently transferring the infection to the face.

Regarding treatment, there is a myth claiming that antibiotics fight this illness. The truth is that they generally do not work to treat it, while other medications may help speed up recovery, alongside the necessity of drinking fluids and resting.

The Truth About the Flu Vaccine and Prevention

Some believe that the vaccine causes the illness, which is incorrect for the following reasons:

Injectable vaccine: It consists of inactive viruses, so it cannot cause infection.
Nasal spray vaccine: It consists of live viruses, but they are weakened and attenuated so they do not cause the disease.

Some mild symptoms may appear as a reaction to the vaccine, such as swelling and redness at the injection site, or a headache and mild fever. The nasal spray may cause a cough, sore throat, or vomiting; these are temporary conditions.

For prevention, the following is recommended:

Wash hands frequently and avoid touching the face.
Clean household surfaces daily.
Cover the mouth and nose when coughing or sneezing.
Stay away from infected individuals.
Get 15 minutes of morning sunlight to obtain Vitamin D, which supports immunity.
Get the appropriate vaccine based on age and health status after consulting a doctor.
