The coronavirus was first detected in Wuhan, China in December 2019. Chinese authorities confirmed it was a new coronavirus called 2019-nCoV. Coronaviruses can cause illnesses ranging from the common cold to more severe diseases like SARS. Prevention methods include frequent hand washing, coughing into the elbow, avoiding contact with sick people, and thoroughly cooking animal products. The virus causes respiratory failure and in some cases brain infection, with death resulting primarily from respiratory failure. It spreads through respiratory secretions like coughing and sneezing. Diagnosis involves laboratory tests on respiratory specimens and blood. Some potential treatments showing effectiveness include protease inhibitors and interferon.

2. HISTORY OF CORONA VIRUS:
• On 31 December 2019, WHO was alerted to several cases of pneumonia
in Wuhan City, Hubei Province of China. The virus did not match any
other known virus. This raised concern because when a virus is new, we
do not know how it affects people.
• One week later, on 7 January, Chinese authorities confirmed that they
had identified a new virus. The new virus is a coronavirus, which is a
family of viruses that include the common cold, and viruses such as
SARS and MERS. This new virus was temporarily named “2019-nCoV.”

5. PREVENTION
• Frequently clean hands by using alcohol-based hand rub or soap and
water.
• When coughing and sneezing cover mouth and nose with flexed elbow
or tissue – throw tissue away immediately and wash hands.Avoid close
contact with anyone who has fever and cough.
• If you have fever, cough and difficulty breathing seek medical care early
and share previous travel history with your health care provider.

6. ....
• When visiting live markets in areas currently experiencing cases of novel
coronavirus, avoid direct unprotected contact with live animals and
surfaces in contact with animals;
• The consumption of raw or undercooked animal products should be
avoided. Raw meat, milk or animal organs should be handled with care,
to avoid cross-contamination with uncooked foods, as per good food
safety practices.

7. CAUSE OF DEATH
• Infection of humans with the
severe acute respiratory
syndrome coronavirus (SARS-
CoV) results in substantial
morbidity and mortality, with
death resulting primarily from
respiratory failure. While the
lungs are the major site of
infection, the brain is also
infected in some patients.

8. How is coronavirus transmitted?
• Transmission. MERS-CoV, like
other coronaviruses, likely
spreads from an infected person's
respiratory secretions, such as
through coughing. ... Infected
people have spread MERS-CoV
to others in healthcare settings,
such as hospitals.

9. How is coronavirus diagnosed?
• Diagnosis. Your healthcare provider may order laboratory tests on
respiratory specimens and serum (part of your blood) to detect human
coronaviruses. Laboratory testing is more likely to be used if you have
severe disease or are suspected of having MERS.

10. Medicines..
• Protease inhibitors (eg,
lopinavir/ritonavir) demonstrated
antiviral activity against severe
acute respiratory syndrome
coronavirus (SARS-CoV)
infection. Interferon alfa and
interferon beta have activity
against SARS-CoV in vitro and
in animal models.
