Flu or influenza is a common viral infection that can affect anyone regardless of their age. In general, flu cases tend to rise between early October and late May, with seasons changing. It is possible to lower the risk of flu. However, several misconceptions about the infection can increase the vulnerability of being affected. Here are some of the common flu myths debunked to lower the risk of contracting and spreading the virus.

1. One can get infected just once each flu season
Influenza viruses are commonly categorized into Type A and Type B. As both types cause similar symptoms, it is difficult to determine which type has infected one unless they undergo a blood test. So, when one is infected with one of the influenza viruses, the immune system releases antibodies that kill off the virus. Also, the antibodies work to prevent future infection by the same virus. So, the risk of getting infected by the specific type of influenza virus for the second time is quite low. However, one does not acquire immunity against the other type. So, they can get infected twice in the same season.

2. The flu is just a bad cold
Many assume that the flu is the worst version of the common cold, as both can cause similar symptoms. Although both are treated in a similar manner, the common cold is a milder concern and usually lasts longer. However, flu can progress suddenly and generally lasts for about 2 to 3 days. It is highly contagious and may require emergency medical care if the symptoms worsen. Here are a few symptoms of the flu that can help to distinguish it from the common cold.

– Fever of 102°F or higher
– Vomiting and nausea
– Sweats and chills
– Stuffy nose
– Pain in the chest
– Muscle aches and headaches
– Cough
– Loss of appetite

3. A flu shot can cause an infection
It is a misconception that one can contract the flu by getting a flu shot. The viral components that are used to make the influenza shots are weakened or inactive. These are not capable of attacking the immune system and causing flu symptoms. Moreover, these shots go through stringent tests and monitoring before they are released for mass usage. Although there might be certain side effects, such as pain at the site of insertion and fever, it does not cause flu.

4. One should feed a cold, starve a fever
This common flu myth can do more harm than good. If one has the flu and is experiencing a fever, they need to stay hydrated all the time. The fluids can help manage the high temperature caused by an overactive immune system. Additionally, one should not eat too little or eat too much depending on whether they have a cold or a fever. Even if appetite is quite low, it is important that one has enough fluids and well-balanced meals to help the immune system fight the virus. Also, proper nutrition can help one manage the symptoms.

5. The flu cannot be treated
Flu caused by influenza virus does not have a quick cure. However, treatment options for the infection do exist. These help in managing the symptoms and alleviating the discomfort. Health practitioners generally offer prescriptions that help one get relief from symptoms like fever, headaches, and body pains. Also, the management options can reduce the duration of being sick by helping them feel better faster and lowering the risk of passing on the infection to others. In addition, staying hydrated and getting enough rest can help one recover faster.

6. Stomach flu is the same as the flu
Stomach flu is an infection caused by gastrointestinal viruses affecting the intestines and the digestive system. Some of its common symptoms include vomiting, nausea, body aches, abdominal pain, constipation, and diarrhea. Although some of the symptoms can be similar to regular flu, stomach flu is not the same as the infection caused by the influenza virus.

7. Exposure to cold weather is a risk factor
It is only possible to catch the flu if one has been exposed to the influenza virus. The chances of contracting the flu are not influenced by cold weather, weather-appropriate clothing, or stepping out with wet hair. However, one may experience flu-like symptoms such as fever, cold, or sore throat due to the cold weather. Further, as the flu season generally coincides with colder months, it is easy to assume that one can catch the flu by being exposed to the cold or being drenched.

8. If one does not feel sick, they cannot spread the flu
In some cases, one may be infected by the flu but may not show any symptoms. According to research, approximately 50% of influenza infections are considered to be asymptomatic. However, even if one cannot see any symptoms, they are still at risk of spreading the virus. They may pass it on to others through touch or close contact. However, the chances of spreading the infection here are lower than if one has the symptoms. Yet, if one has been exposed to the influenza virus, they should maintain a safe distance from others to avoid asymptomatic transmission.

9. The flu is not a serious concern
According to the CDC, approximately 140,000 to 810,000 people were hospitalized with influenza each year during the period between 2010 and 2020. Also, it has been reported that influenza causes around 12,000 and 61,000 deaths every year. People at high risk, such as children, seniors, immunocompromised persons, and those with pre-existing health conditions, may develop severe complications due to flu. So, it is crucial to take flu symptoms seriously and seek timely treatment to avoid complications.

One should consult a doctor to discuss suitable treatment options and preventive measures based on their unique healthcare needs.
