reached us, precaution, experimental medicine, end of the video research articles
from which we collected this information.
2. The Name COVID 19
• Initially, virus was labelled as 2019-nCoV.
• International Committee on Taxonomy of Viruses
designated it as the SARS-CoV-2 virus.
• February 2020, World Health Organization (WHO)
announced the disease caused by SARS-CoV-2
novel virus as Coronavirus disease-2019 (COVID-
19).
5. History and Origin
• SARS-CoV caused severe acute respiratory
syndrome outbreaks in 2002 and 2003 in
Guangdong Province, China.
• MERS-CoV severe respiratory disease
outbreaks in 2012 in Middle East.
• SARS-CoV-2 out break in December 2019,
Wuhan China
7. Consequence of COVID 19
Chest Radiographs. Shown are chest radiographs from Patient 2 on days 8 and 11 after the onset of illness. The trachea
was intu-bated and mechanical ventilation instituted in the period between the acquisition of the two images. Bilateral
fluffy opacities are present in both images but are in-creased in density, profusion, and confluence in the second image;
these changes are most marked in the lower lung fields. Changes consistent with the accumu-lation of pleural liquid are
also visible in the second image.
Symtoms: Cold, Fever, body pain, difficulty in breathing
9. Precaution is only cure
• Avoid close contact with subjects suffering from acute
respiratory infections.
• Wash your hands frequently
• Avoid unprotected contact with farm or wild animals.
There is no specific antiviral treatment recommended
for COVID-19, and no vaccine is currently available.
Oxygen therapy represents the major treatment
intervention for patients with severe infection.
10. Experimental medicine
Inappropriate administration of antibiotics
should be avoided,
*’’Although no antiviral treatments have been
approved, several approaches have been
proposed such as lopinavir/ritonavir (400/100
mg every 12 hours), chloroquine (500 mg every
12 hours), and hydroxychloroquine (200 mg
every 12 hours). Alpha-interferon (e.g., 5
million units by aerosol inhalation twice per day)
is also used.’’
