Revenues of hand sanitizers have risen since the outbreak of COVID-19

It's become such a popular drug that pharmacies and supermarkets have begun to restrict the amount customers can buy at once. The state of New York has also announced it will begin to manufacture its own hand sanitizer to satisfy demand. While hand sanitizers that help reduce our risk of catching certain infections, not every hand sanitizer are equally effective against coronaviRUs with other viral bacterial infections – including chronic cold and flu – the innovative coronavirus (called SARS-CoV-2) is predominantly transmitted when virus-laden droplets are moved from a person's mouth or nose to others. Recent research, however, has indicated it can spread by faeces as well.rus.Rinsing using warm water and soap becomes the gold standard for sanitation and prevents infectious diseases from spreading. Washing with hot water (not cold water) and soap extracts oils that can host bacteria from our hands. Two main categories of hand sanitizers are available: alcohol-based and alcohol-free. Hand sanitizers focused on alcohol produce different quantities and alcohol forms, typically between 60 per cent and 95 per cent, and generally isopropyl alcohol, ethanol (ethyl alcohol) or n-propanol. It's well known that alcohol can kill most germs.

Instead of alcohol, alcohol-free hand sanitizers produce anything called quarterly oxides compounds (normally benzalkonium chloride). It can even decrease microbes because they are less powerful than alcohol.

Tearing down viruses: Alcohol starts attacking the protein surface covering some viruses including coronaviruses. The protein is essential to the survival and replication of a virus. But to kill most viruses, a hand sanitizer needs to be at least 60 percent alcohol. Sanitizing wipes with less than 60 per cent alcohol have also been found to be less effective in destroying bacteria and fungi and may only decrease germ growth rather than kill them outright. And only 60 per cent alcohol- hand sanitizers can not kill all kinds of germs. Studies have shown that hand washing is more efficient at eliminating norovirus, Cryptosporidium (a parasite that can trigger diarrhoea), and Clostridium difficile (bacteria that trigger bowel problems and diarrhoea) than hand sanitisers.

Despite shortages causing some people to try to produce their own hand sanitizers, it is also important to note that these might not be as successful as the ones that are widely available. Sneezing or coughing your hands would often take more than just a hand sanitizer pump to disinfect them. That is because the hand sanitizer may not function as well if the hands are infected with mucous as mucous serves to protect microbes.

As a consequence, the safest and most effective way of avoiding coronavirus spread – and reducing the chance of contracting it – remains to wash your hands as the first choice with soap and water, and stop touching your face as much as possible. Yet hand sanitizers based on alcohol (with at least 60 percent alcohol) are a realistic option when there is no soap and water. When you then use a hand sanitizer, much like washing your hands with soap and water, you need to make sure that you thoroughly cover your hands (including between your knuckles, wrists, palms, back of your hand and fingernails) and rub them in for at least 20 seconds, and that's all you need.
