The new coronavirus is officially called SARS-CoV-2, which stands for severe acute respiratory syndrome coronavirus 2. An infection with this virus can lead to coronavirus disease 19, or COVID-19.
SARS-CoV-2 is related to the coronavirus SARS-CoV, which caused another kind of coronavirus disease in 2002 to 2003. However, from what we know so far, SARS-CoV-2 is different from other viruses, including other coronaviruses. The evidence shows that SARS-CoV-2 may be transmitted more easily and cause life-threatening illness in some people. Like other coronaviruses, it can survive in the air and on surfaces long enough for someone to contract it. It’s possible that you could acquire SARS-CoV-2 if you touch your mouth, nose, or eyes after touching a surface or object that has the virus on it. However, this is not thought to be the main way that the virus spreads However, SARS-CoV-2 multiplies faster in the body even when you don’t have symptoms. Additionally, you can transmit the virus even if you never get symptoms at all. Some people have mild to moderate symptoms only, while others have severe COVID-19 symptoms.
Tips for prevention
Follow the guidelines to help protect yourself from contracting and transmitting SARS-CoV-2.

1. Wash your hands frequently and carefully

Use warm water and soap and rub your hands for at least 20 seconds. Work the lather to your wrists, between your fingers, and under your fingernails. You can also use an antibacterial and antiviral soap. Use hand sanitizer when you cannot wash your hands properly. Rewash your hands several times a day, especially after touching anything, including your phone or laptop.

2. Avoid touching your face

SARS-CoV-2 can live on some surfaces for up to 72 hours. You can get the virus on your hands if you touch a surface like:
  • gas pump handle
  • your cell phone
  • a doorknob
Avoid touching any part of your face or head, including your mouth, nose, and eyes. Also avoid biting your fingernails. This can give SARS-CoV-2 a chance to go from your hands into your body.

3. Stop shaking hands and hugging people — for now

Similarly, avoid touching other people. Skin-to-skin contact can transmit SARS-CoV-2 from one person to another.

4. Don’t share personal items

Do not share personal items like:
  • phones
  • makeup
  • combs
It’s also important not to share eating utensils and straws. Teach children to recognize their reusable cup, straw, and other dishes for their own use only. Prevention | Coronavirus COVID-19 information

5. Cover your mouth and nose when you cough and sneeze

SARS-CoV-2 is found in high amounts in the nose and mouth. This means it can be carried by air droplets to other people when you cough, sneeze, or talk. It can also land on hard surfaces and stay there for up to 3 days. Use a tissue or sneeze into your elbow to keep your hands as clean as possible. Wash your hands carefully after you sneeze or cough, regardless. How to protect yourself against coronavirus | World news | The ...

6. Clean and disinfect surfaces

Use alcohol-based disinfectants to clean hard surfaces in your home like:
  • countertops
  • door handles
  • furniture
  • toys
Also, clean your phone, laptop, and anything else you use regularly several times a day. Disinfect areas after you bring groceries or packages into your home. Use white vinegar or hydrogen peroxide solutions for general cleaning in between disinfecting surfaces. Cleaning and Disinfecting | Multnomah County

7. Take physical (social) distancing seriously

If you’re carrying the SARS-CoV-2 virus, it’ll be found in high amounts in your spit (sputum). This can happen even if you don’t have symptoms. Physical (social) distancing, also means staying home and working remotely when possible. If you must go out for necessities, keep a distance of 6 feet (2 m) from other people. You can transmit the virus by speaking to someone in close contact to you. Can You Socialize Safely During the COVID-19 Pandemic? | Time

8. Do not gather in groups

Being in a group or gathering makes it more likely that you’ll be in close contact with someone. This includes avoiding all religious places of worship, as you may have to sit or stand too close to another congregant. It also includes not congregating at parks or beaches.

9. Avoid eating or drinking in public places

Now is not the time to go out to eat. This means avoiding restaurants, coffee shops, bars, and other eateries. The virus can be transmitted through food, utensils, dishes, and cups. It may also be temporarily airborne from other people in the venue. You can still get delivery or takeaway food. Choose foods that are thoroughly cooked and can be reheated. High heat (at least 132°F/56°C, according to one recent, not-yet-peer-reviewed lab study) helps to kill coronaviruses. This means it may be best to avoid cold foods from restaurants and all food from buffets and open salad bars. What to Do If You Fear Eating in Public

10. Wash fresh groceries

11. Wear a (homemade) mask

The Centers for Disease Control and Prevention (CDC) recommendsTrusted Source that almost everyone wears a cloth face mask in public settings where physical distancing may be difficult, such as grocery stores. When used correctly, these masks can help prevent people who are asymptomatic or undiagnosed from transmitting SARS-CoV-2 when they breathe, talk, sneeze, or cough. This, in turn, slows the transmission of the virus. The CDC’s website provides instructionsTrusted Source for making your own mask at home, using basic materials such as a T-shirt and scissors. Some pointers to keep in mind:
  • Wearing a mask alone will not prevent you from getting a SARS-CoV-2 infection. Careful handwashing and physical distancing must also be followed.
  • Cloth masks aren’t as effective as other types of masks, such as surgical masks or N95 respirators. However, these other masks should be reserved for healthcare workers and first responders.
  • Wash your hands before you put on your mask.
  • Wash your mask after each use.
  • You can transfer the virus from your hands to the mask. If you’re wearing a mask, avoid touching the front of it.
  • You can also transfer the virus from the mask to your hands. Wash your hands if you touch the front of the mask.
  • A mask shouldn’t be worn by a child under 2 years old, a person who has trouble breathing, or a person who can’t remove the mask on their own.
