I. FACTS ABOUT COVID-19

What is COVID-19? 

COVID-19 is a disease caused by a new strain of coronavirus. ‘CO’ stands for corona, ‘VI’ for virus, and

‘D’ for disease. Formerly, this disease was referred to as ‘2019 novel coronavirus’ or ‘2019-nCoV.’

The COVID-19 virus is a new virus linked to the same family of viruses as Severe Acute Respiratory

Syndrome (SARS) and some types of common cold.

What are the symptoms of COVID-19? 

Symptoms can include fever, cough and shortness of breath. In more severe cases, infection can cause

pneumonia or breathing difficulties. More rarely, the disease can be fatal. These symptoms are similar to

the flu (influenza) or the common cold, which are a lot more common than COVID-19. This is why testing

is required to confirm if someone has COVID-19.

How does COVID-19 spread? 

The virus is transmitted through direct contact with respiratory droplets of an infected person (generated

through coughing and sneezing). Individuals can also be infected from and touching surfaces

contaminated with the virus and touching their face (e.g., eyes, nose, mouth). The COVID-19 virus may

survive on surfaces for several hours, but simple disinfectants can kill it.

Who is most at risk? 

We are learning more about how COVID-19 affects people every day.  Older people, and people with

chronic medical conditions, such as diabetes and heart disease, appear to be more at risk of developing

severe symptoms.  As this is a new virus, we are still learning about how it affects children. We know it is

possible for people of any age to be infected with the virus, but so far there are relatively few cases of

COVID-19 reported among children. This is a new virus and we need to learn more about how it affects

children. The virus can be fatal in rare cases, so far mainly among older people with pre-existing medical

conditions.

What is the treatment for COVID-19? 

There is no currently available vaccine for COVID-19. However, many of the symptoms can be treated

and getting early care from a healthcare provider can make the disease less dangerous. There are

several clinical trials that are being conducted to evaluate potential therapeutics for COVID-19.

How can the spread of COVID-19 be slowed down or prevented?

As with other respiratory infections like the flu or the common cold, public health measures are critical to

slow the spread of illnesses. Public health measures are everyday preventive actions that include:

✓ staying home when sick;

✓ covering mouth and nose with flexed elbow or tissue when coughing or sneezing. Dispose of

used tissue immediately;

✓ washing hands often with soap and water; and

✓ cleaning frequently touched surfaces and objects.

As we learn more about COVID-19 public health officials may recommend additional actions.

Explanation:

A red blood cell will swell and undergo hemolysis (burst) when placed in a hypotonic solution. When placed in a hypertonic solution, a red blood cell will lose water and undergo crenation (shrivel)
