Learn the correct ways to prevent the novel coronavirus and avoid misinformation that could affect your health safety during an outbreak.

Facts About Preventing the Novel Coronavirus

Inaccurate beliefs about protection from infection are common; it is essential to distinguish fact from myth:

Dietary Supplements and Herbs: Taking zinc, vitamin C, garlic, or herbs supports the immune system, but they do not prevent infection if the virus enters the body. However, high doses of vitamin C may be used as a treatment based on clinical trials, though large doses may cause diarrhea and stomach upset.
Heat and Water: Exposing the body to high heat (such as using a hairdryer or hot water) does not prevent infection and may cause health damage. Similarly, drinking water every 15 minutes does not kill the virus or prevent it from reaching the lungs.
Surgical Masks: These masks are designed to prevent droplets from leaving an infected person and do not provide complete protection for the wearer; meanwhile, N95 masks prevent viruses from entering the nose.
Saline Solutions: Nasal rinsing and gargling with salt may improve cold symptoms, but they do not protect against the novel coronavirus, and excessive use may harm innate immune components.

Symptoms of the Virus and How to Manage Them

Symptoms typically appear within 2 to 14 days of exposure and include:

Fever and chills.
Dry cough and shortness of breath.
Severe fatigue, headache, and muscle aches.
Loss of taste or smell.
Digestive disturbances such as vomiting or diarrhea.

Regarding medications, research is ongoing concerning the effect of anti-inflammatories like ibuprofen. Opinions vary; some warnings suggest the possibility of worsening the infection, while other health entities state there is insufficient evidence to confirm an increased risk of infection when using them.

Asthma Patients and the Virus

People with severe respiratory problems, such as asthma, are more susceptible to serious complications because their lung function is lower than normal, which reduces oxygen reserves during infection.

Regarding medications, there is insufficient evidence that inhaled steroids or montelukast increase the risk of infection. However, some types of steroid hormones (Glucocorticoids) may put a person at greater risk because they suppress the body’s natural cortisol response to infection.

Additional tips for asthma patients:

Adhere to daily prescribed medications to reduce the risk of asthma attacks.
Maintain an adequate supply of inhalers.
Quit smoking and manage stress.

Prevention Methods and Social Distancing

Protection from the novel coronavirus relies on the following precautionary measures:

Personal Hygiene: Wash hands with soap and water for 20 seconds, or use an alcohol-based sanitizer with at least 60% concentration.
Physical Distancing: Maintain a distance of 6 feet between people and avoid shaking hands or kissing.
Environment: Ensure indoor spaces are well-ventilated, avoid public transportation, and disinfect touched surfaces.
Vaccines: Receiving the latest vaccine doses helps avoid severe cases and reduces the need for hospitalization.

FAQ

What is the relationship between asthma and the symptoms of the virus?

Infection causes respiratory problems, and since asthma patients have lower lung capacity, they may experience more severe symptoms and more dangerous complications compared to healthy individuals.

Do asthma medications increase the risk of infection?

There is insufficient evidence suggesting that preventive medications such as inhaled steroids increase the risk, but some types of hormonal steroids may reduce the body’s ability to respond to stress and infection.

Who should receive the latest version of the COVID-19 vaccine?

It is recommended to adhere to receiving updated vaccines to avoid severe cases of the disease and to limit the possibilities of death or hospital care.

When to Visit a Doctor?

Seek emergency help immediately if the following signs appear:

For adults: Severe difficulty breathing, persistent chest pain or pressure, lips or nails turning blue or gray, or sudden mental confusion.
For children: Dizziness, signs of dehydration (such as few tears or decreased urination), persistent vomiting and diarrhea for more than 24 hours, or a fever that does not drop.
