Steering clear of the things that can spread germs is the best way to protect yourself. To do that: Wash your hands. Washing your hands well and often is the best way to beat germs. Wash your hands every time you cough or sneeze, before you eat or prepare foods, after you use the bathroom, after you touch animals and pets, after you play outside, and after you visit a sick relative or friend. There is a right way to wash your hands. Use warm or cold water and soap and rub your hands together for at least 20 seconds, which is about how long it takes to sing "Happy Birthday" twice.
Cover up. Cover your nose and mouth when you sneeze and cover your mouth when you cough to keep from spreading germs. Use a tissue when you can, and then throw it away. Get your immunizations.
No one likes to get shots , but these help keep your immune system strong and prepared to battle germs. Take care of your immune system. Help keep your immune system strong and healthy by eating well, exercising regularly, and getting good sleep. All this will help you to be prepared to fight germs that cause illness.
One aspect that has been unclear is exactly how long Sars-CoV-2, the name of the virus that causes the disease Covid, can survive outside the human body. Some studies on other coronaviruses, including Sars and Mers, found they can survive on metal, glass and plastic for as long as nine days , unless they are properly disinfected.
Some can even hang around for up to 28 days in low temperatures. Coronaviruses are well known to be particularly resilient in terms of where they can survive. And researchers are now beginning to understand more about how this affects the spread of the new coronavirus.

Their study, which has been published in the New England Journal of Medicine , shows that the virus could survive in droplets for up to three hours after being coughed out into the air. Fine droplets between micrometres in size — about 30 times smaller than the width of a human hair — can remain airborne for several hours in still air.
It means that the virus circulating in unfiltered air conditioning systems will only persist for a couple of hours at the most, especially as aerosol droplets tend to settle on surfaces faster in disturbed air. But the NIH study found that the Sars-CoV-2 virus survives for longer on cardboard — up to 24 hours — and up to days on plastic and stainless-steel surfaces.

The findings suggest the virus might last this long on door handles, plastic-coated or laminated worktops and other hard surfaces.
Another more recent study released in May by microbiologists in Beijing, China, found that Sars-CoV-2 could survive and remain infectious on smooth surfaces including plastic, stainless steel, glass, ceramics and latex gloves for up to seven days.

In fact, while cold viruses can live for several days, their ability to cause infection decreases after approximately 24 hours, and after only five minutes, the amount of flu virus on hands fall to low levels, making transmission much less likely.
The best defense against active viruses remains thorough hand washing. In addition, wiping down surfaces with anti-bacterial or alcohol-based cleaners will help kill viruses and decrease the chances of transmission.
