What is the coronavirus

Coronaviruses are a large family of viruses that can cause illness ranging from the common cold to more severe diseases like Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).

How is the virus transmitted

Current estimates of the incubation period of the virus range from 2–10 days, but more information about the mode of transmission is needed to confirm this. Experts are also still unclear whether transmission can occur from
asymptomatic individuals or during the incubation period.

To prevent the spread of the novel coronavirus, the public should follow standard infection prevention recommendations including regular hand washing, covering the mouth and nose when coughing and sneezing, and
thoroughly cooking meat and eggs. Where possible, people should avoid close contact with persons showing symptoms of respiratory illness, including coughing and sneezing.

What are the symptoms

Doctors are learning new things about this virus every day. So far we know that COVID-19 may not initially cause any symptoms.

You may carry the virus for 2 days or up to 2 weeks

Some common symptoms that have been specifically linked to the 2019 coronavirus include:

  • feeling short of breath.
  • having a cough that gets more severe over time.
  • a low-grade fever that gradually increases in temperature.

The main symptoms that have been specifically linked to the 2019 coronavirus include:

COVID-19 versus the flu:-

The symptoms of COVID-19 are similar to that of the influenza (flu) virus.

some common symptoms of a flu infection:

  • runny or stuffy nose.
  • cough.
  • sneezing.
  • sore throat.
  • fever.headache.
  • fatigue.
  • chills.
  • body aches.

What causes coronaviruses

Coronaviruses are zoonotic. This means they first develop in animals before developing in humans.

Once the virus develops in people, coronaviruses can be spread from person to person through respiratory droplets. This is a technical name for the wet stuff that moves through the air when you cough or sneeze.

The viral material hangs out in these droplets and can be breathed into the respiratory tract (your windpipe and lungs), where the virus can then lead to an infection.The 2019 coronavirus hasn’t been definitively linked to a specific animal.

Increased risk

Washing your hands and disinfecting surfaces can help decrease your risk for catching this or other viruses.

How are coronaviruses diagnosed.

The 2019 coronavirus can be diagnosed similarly to other viral infections: using a blood, saliva, or tissue sample.

Talk to your doctor right away if you think you have a coronavirus infection, especially if you’ve traveled to China in the past 14 days. Your doctor will speak to local public health officials to provide guidance on whether
testing for the virus is needed.

A lab technician will either draw a sample of your blood with a needle or use a cotton swab to take a small sample of saliva or respiratory secretions from your nose or the back of your throat.


There’s currently no treatment specifically approved for the 2019 coronavirus, and no cure for an infection, although treatments and vaccines are currently under study. Instead, treatment focuses on managing symptoms as the
virus runs its course.

Seek immediate medical help if you think you have COVID-19. Than your doctor will recommend treatment for any symptoms

Other coronaviruses like SARS and MERS do have vaccines and treatments. Some treatments for these similar viruses include:

  • antiviral or retroviral medications
  • breathing support like mechanical ventilation
  • steroids to reduce lung swelling
  • blood plasma transfusions
