How does one catch the coronavirus?
COVID-19, the illness caused by the coronavirus, starts with droplets from an infected person’s cough, sneeze, or breath. They could be in the air or on a surface that you touch before touching your eyes, nose, or mouth. That gives the virus a passage to the mucous membranes in your throat.
What is a disease outbreak?
A disease outbreak is the occurrence of disease cases in excess of normal expectancy. The number of cases varies according to the disease-causing agent, and the size and type of previous and existing exposure to the agent. Disease outbreaks are usually caused by an infection, transmitted through person-to-person contact, animal-to-person contact, or from the environment or other media. Outbreaks may also occur following exposure to chemicals or to radioactive materials.
Is there a difference between the coronavirus disease and COVID-19?
COVID-19 is the name of the disease caused by the new coronavirus that is called SARS-CoV-2, or sometimes just “novel coronavirus”.
Why COVID-19 is called the novel coronavirus?
The word “novel” originated from the Latin word “novus,” which means “new.” In medicine, “novel” usually refers to a virus or bacterial strain that was not previously identified.
What are coronaviruses?
Coronaviruses are a large family of viruses. Some coronaviruses cause cold-like illnesses in people, while others cause illness in certain types of animals, such as cattle, camels, and bats. Some coronaviruses, such as canine and feline coronaviruses, infect only animals and do not infect people.
Can the coronavirus survive on surfaces?
It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.
