Face masks always protect against coronavirus
Healthcare workers use professional face masks, which fit tightly around the face, to protect themselves from infection.
Disposable masks are unlikely to provide such protection, and they will not block tiny viral particles. However, a cloth mask can help prevent the spread of droplets.
The Centers for Disease Control and Prevention (CDC) recommend that all people wear cloth face masks in public places where it is difficult to maintain a 6-foot (2-meter) distance from others. This will help slow the spread of the virus from asymptomatic people and those who do not know that they have contracted it.
When wearing a mask, it is essential to continue with other precautions, such as not touching the face and practicing physical distancing.
Instructions for making masks at home are available here.
Surgical masks and N95 respirators provide greater protection, but these are reserved for healthcare workers only.
Rinsing the nose with saline protects against coronavirus
There is no evidence to suggest that a saline nose rinse protects against respiratory infections. Some research suggests that this technique might reduce the symptoms of acute upper respiratory tract infections, but scientists have not found that it can reduce the risk of infection.
Spraying chlorine or alcohol on the skin kills viruses in the body
Applying alcohol or chlorine to the body can cause harm, especially if it enters the eyes or mouth. Although people can use these chemicals to disinfect surfaces, they should not use them on the skin.
These products cannot kill viruses within the body.
Only older adults and young people are at greater risk
SARS-CoV-2, like other coronaviruses, can infect people of any age. However, older adults and individuals with preexisting health conditions, such as diabetes or asthma, are more likely to become severely ill.
Garlic protects against coronaviruses
Some research suggests that garlic might slow the growth of some species of bacteria. However, COVID-19 is caused by a virus, and there is no evidence to suggest that garlic can protect people against COVID-19.
Home remedies can cure and protect against COVID-19
No home remedies can protect against COVID-19. This goes for vitamin C, essential oils, silver colloid, sesame oil, garlic, fish tank cleaner, burning sage, and sipping water every 15 minutes.
The best approach is to adopt a good hand-washing regimen and to avoid places where there may be sick people.
Parcels from China can spread coronavirus
From previous research into similar coronaviruses, including those that cause SARS and MERS and are similar to SARS-CoV-2, scientists believe that the virus cannot survive on letters or packages for an extended period of time.
The CDC explain that “because of poor survivability of these coronaviruses on surfaces, there is likely very low risk of spread from products or packaging that are shipped over a period of days or weeks at ambient temperatures.”
The virus will die off when temperature rises in the sun
Some viruses, such as cold and flu viruses, do spread more easily in the colder months, but that does not mean that they stop entirely when conditions become milder.
As it stands, scientists do not know how temperature changes will influence the behavior of SARS-CoV-2.
Coronavirus is the deadliest virus known to humans
Although SARS-CoV-2 does appear to be more serious than influenza, it is not the deadliest virus that people have faced. Others, such as Ebola, have higher mortality rates.
5G helps SARS-CoV-2 spread
As the world becomes more connected, some regions are rolling out 5G mobile technology. A raft of conspiracy theories appear wherever this technology sets foot.
One of the most recent theories to emerge is that 5G is responsible for the swift spread of SARS-CoV-2 across the globe.
Some people claim that 5G helps viruses communicate, often citing a paper from 2011. In this study, the authors conclude that bacteria can communicate via electromagnetic signals. However, experts dispute this theory, and SARS-CoV-2 is a virus, not a bacterium.
Wuhan was one of the first cities to trial 5G in China, which helps explain the origin of some of these theories. However, Beijing, Shanghai, and Guangzhou also rolled out 5G at a similar time.
It is also worth noting that COVID-19 has significantly impacted countries with very little 5G coverage, such as Iran.
