What is COVID-19?

Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus (2019).

Coronavirus is a type of virus that typically circulates among animals and some would ‘spillover’ to the human population. An example of this would be the SARS coronavirus (China,2002) and MERS coronavirus (Saudi Arabia,2012).

COVID-19 was first identified in China last December 2019 among a cluster of people who had pneumonia. From there, it quickly spread to over 202 countries, areas or territories and affected more than 500,00 people around the world so far.

It has since been classified as a Pandemic by the World Health Organization (WHO).

How is it transmitted?

  1. Droplet

It is transmitted via droplet transmission,or tiny droplets of liquid from the mouth and nose when you cough, sneeze or even speak.

When you sneeze or cough, the droplets would go into the eyes, nose or mouth of another person and therefore infect that other person.

  1. Fomites

Sometimes droplets settle onto surfaces (table, clothes, doorknobs and etc.) and people would come in contact with these contaminated surfaces. If they touch their face, eyes, mouth or nose, they can get infected by the virus as well.

What are the symptoms?

The COVID-19 virus affects different people in different ways.  COVID-19 is a respiratory disease and most infected people will develop mild to moderate symptoms and recover without requiring special treatment.  People over 60 years old and those who have underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer have a higher risk of developing severe disease and death.

Common symptoms include:

  • fever
  • tiredness
  • dry cough.

Other symptoms include:

  • shortness of breath
  • aches and pains
  • sore throat
  • and very few people will report diarrhea, nausea or a runny nose.

Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.

How do I keep myself from being infected?

  1. Wash your hands
    This is the easiest and most effective way of protecting yourself from the virus. Coronavirus particles are coated by a fatty layer and are easily destroyed by soap and water. An alcohol-based rub is also recommended if you don’t  have access to soap and water.This is the proper handwashing procedure according to WHO:
  2. Respiratory Etiquette
    Whenever you sneeze or cough, cover your nose and mouth with a tissue. Dispose your tissue in a closed container and wash your hands.OrSneeze into your elbow and not on your hands.
  3. Be Informed
    This is a new virus and little is known about it. Everyday, there are new discoveries on how it spread or how it is treated so we have to keep ourselves informed always.
  4. Practice Physical Distancing
    As it is passed on  through droplet transmission, it is important to distance yourself from other people. WHO recommends people to stay home to protect themselves and other people.
  5. Keep Surfaces Clean
    As a good rule of thumb, it is important to make sure that all the surfaces we come in contact with are free of coronavirus. Make sure to use a good disinfectant and focus on high-contact surfaces like tables, couches and doorknobs.
    A good way to disinfect large spaces is to look into whole room disinfection. During this process, a trained professional comes in with a non-toxic disinfectant and sprays the entire room. This is recommended for large spaces because it takes only minimal effort but with maximum effectiveness. This can also be effective in residential spaces because unlike bleach and other mechanical disinfectants, it works on all types of surfaces without causing any damage.Purify Global provides high level disinfection services, specializing in end-use fogging application on various types of surfaces for advanced disinfection.Our services ensure thorough disinfection for both high-contact and low-contact areas, effectively prevents recontamination, and sets to improve the quality of life for employees, patients, and the general population.
