What is a pandemic? Is there a risk of coronavirus (Covid-19) turning into a pandemic?

Metal, Plastic and Paper: How active is the corona virus on which surface? Results According to a recently announced study, the COVID-19 virus that causes coronavirus disease can remain stable (transmissible) on some surfaces for up to 3 days. Scientists have announced that the deadly corona virus that causes severe acute respiratory syndrome can remain infectiously active in aerosols (spreading in the form of droplets in the air) for up to 3 hours, up to 4 hours on copper surfaces, up to 24 hours on cardboard, and 2 to 3 days on plastic and stainless surfaces. Published in the prestigious journal New England Journal of Medicine (NEJM), the research was conducted by scientists from many universities.

How long does the coronavirus survive on air and metal surfaces?
The easiest way of transmission of COVID-19 virus is explained as contact with metal and plastic surfaces, while it poses a high risk of cough from close range. The coronavirus's active residence and transmission times on different surfaces are as follows: 
Spread in the air in the form of droplets: up to 3 hours can survive, but air hanging time is very short
Up to 4 hours on copper surfaces,
Up to 24 hours in cardboard, much shorter on newspaper paper
Up to 2 to 3 days on pastic surfaces
Up to 3 days on stainless metal surfaces
Up to 6 hours on clothes and fabric surfaces

At what temperatures do coronaviruses disappear?
It has been determined that COVID-19 viruses cannot remain active at temperatures higher than 30 ºC (Celsius). Therefore, it is emphasized that the epidemic may decrease significantly with the start of summer temperatures.

The most effective methods of protection against coronavirus
The authors of the study state that coronaviruses can be effectively erased by ordinary household disinfectants and can easily disappear if hands are washed for 20 seconds. For example, ordinary home disinfectants containing 62-71% ethanol, 0.5% hydrogen peroxide, or 0.1% sodium hypochlorite destroy corona viruses in a very short time. There is no trace of viruses on the surfaces that are wiped with these, after a maximum of 2 minutes.

Does cologne protect from coronavirus?
According to the research, disinfectant (cologne) containing 70% alcohol and above destroys corona viruses very effectively. Wiping virus-coated surfaces with alcohol and cologne or wiping hands with cologne can be very effective for protection. Other forms of transmission of the COVID-19 virus will continue to be investigated in the study whose preliminary data is disclosed.
Providing information about the results of the study, scientists from the Rocky Mountain Laboratories and the U.S. National Institute for Allergy and Infectious Diseases tried to mimic virus infection on daily surfaces in a home or hospital setting, such as coughing or touching objects.
Scientists then investigated how long the virus remained contagious on these surfaces. Accordingly, COVID-19 can be transmitted similarly to sars and influenza viruses. However, unlike these, people infected with the COVID-19 virus can transmit the infection before the symptoms appear.

What to do to prevent coronavirus infection?
First of all, both healthcare professionals and the public need to apply to the rules of protection applicable to flu. In addition, to avoid coronavirus infection:
Avoid close contact with sick people
Avoid touching your eyes, nose, and mouth
Stay home when you are sick
Cover your cough or sneeze into a handkerchief, then throw it away
Wipe away frequently touched objects and surfaces with a normal household cleaning spray.
