Things you should know about how covid-19 spreads 

While the COVID-19 can be quite harmful to those that catch it, there are numerous ways you can prepare yourself to reduce your chances of getting sick. Sometimes, we can forget how easy it is to spread germs, from sneezing to coughing. When you sneeze, tiny droplets can escape your nose, flying through the air. These droplets can travel 7-8 meters (23-27 feet). Therefore, we must be careful especially when sick, to prevent these germs from spreading.

These droplets of saliva (spit) or discharge come from the noze. If a person is infected with COVID-19, they can spread these particles by coughing or sneezing.

Person-to-Person Contact: The spread of bacteria can occur when people are in close contact with one another, within 2 meters (6 feet). The virus is able to spread from droplets produced by an infected person when they sneeze or cough within this distance of you. Even if you are asymptomatic (you do not feel sick), the disease can still spread. You might carry the virus, and pass it on to others. This is why it is imperative that you stay home, even if you are feeling well. 

Fomites: Are inanimate objects which can transfer diseases to new carriers. Examples of these are towels, kitchenware, furniture and clothes. These surfaces or objects could be contaminated or exposed to infectious agents such as: pathogenic bacteria, fungi or SARS-CoV2. This means that, if you have any bacteria on your hands,  this bacteria can spread from you to an object or surface. If you touch a contaminated surface, and then touch eyes, nose or mouth you are at risk of becoming infected. This can also occur from sneezing or coughing, which will send these droplets to contaminate areas around you. 

This highlights the importance of constantly washing your hands. This can reduce the possibility of transferring the virus to yourself, to others, and to fomites. 

The virus can survive longer on some surfaces than others, such as plastic, metal, and various fabrics. The following figure emphasizes these differences, and how one might be more careful to frequently sanitize these surfaces.

There are still many things currently unknown about the COVID-19 and how it spreads, but it is important to understand that the disease can be spread through things like clothing and items you might be touching in grocery stores and pharmacies. Door handles and shopping carts are an example of items that you should sanitize often.

Incubation period: The time between catching the virus and developing symptoms associated with the disease. The current estimation of this period for COVID-19 is 1-14 DAYS. Most commonly, people develop symptoms around 5 days after catching the virus. This is why you must practice social distancing, to prevent spreading the virus.
