False information spreads rapidly during crises, and the coronavirus pandemic has been no exception. With many unknowingly infected, people are seeking ways to protect themselves—sometimes falling for misinformation. Here are common myths about COVID-19 and the facts behind them:
Claim: Saltwater “flushes out” the virus
False
Saltwater might soothe a sore throat but has no effect on the virus.
Claim: Ozone therapy cures COVID-19
False
Ozone generators are not FDA-approved and pose serious health risks, including lung damage.
Claim: Blood type affects susceptibility
Maybe true
Early studies suggest Type A may have slightly higher risk, and Type O lower risk, but findings are inconclusive. Everyone should follow health guidelines regardless of blood type.
Claim: Warm weather will eliminate the virus
False
The virus spreads globally, including in regions entering winter. Past pandemics didn’t follow seasonal patterns.
Claim: Holding your breath prevents infection
False
Virus-laden droplets can still enter your nose or mouth even if you hold your breath. Cover coughs outdoors.
Claim: Drinking water pushes the virus into stomach acid
False
Once the virus enters cells, it can’t be “washed away.” Excessive water only increases bathroom trips.
Claim: Asymptomatic spread lasts up to two weeks
True
The incubation period is 2–14 days, underscoring the need for social distancing.
Claim: Saunas or blow dryers kill the virus
False
Heat can’t penetrate cells where the virus resides and risks causing burns.
Claim: COVID-19 is airborne
Maybe true
Studies show the virus can linger in air for hours, but transmission via aerosols isn’t confirmed. Medical workers may need added precautions.
Claim: Vitamins grant immunity
False
No evidence supports megadoses of vitamins preventing infection. Focus on a balanced diet.
Claim: Only elderly are at risk
False
All ages can contract COVID-19, though seniors and those with preexisting conditions face higher risks.
Claim: Thermal scanners detect all cases
False
Fever may take days to develop; scanners miss early or asymptomatic infections.
Claim: A rapid 30-minute test exists
True
University of Oxford developed a rapid test, soon to be available for clinics and home use.
Claim: Pets spread COVID-19
False
Humans are more likely to transmit the virus to pets than vice versa.
Claim: Hand-washing beats sanitizer
True
Soap and water remove dirt and pathogens better. Use sanitizer (60%+ alcohol) only when unavailable.
Claim: Bat soup caused the outbreak
False
The virus’s origin remains unclear, but it spreads via droplets—not food.
Claim: Bleach solutions cure COVID-19
False
Drinking bleach is dangerous and ineffective. The FDA warns against these concoctions.
Claim: A 10-second breath-hold confirms health
False
This test is meaningless; symptom-free individuals can still carry the virus.
Claim: Gloves reduce transmission risk
False
Gloves can accumulate germs if reused or touched to surfaces. Frequent hand hygiene is safer.
Prioritize trusted sources like the CDC and WHO, and continue practicing social distancing and thorough handwashing.
