Coronavirus SARS-CoV-2 (COVID-19) What is the difference between pandemic and epidemic? What is Coronavirus? Watch the full video: https://youtu.be/y9zr7M8mBIY

1. THE NEW PANDEMIC
CODVID-19

2. What is the difference
between pandemic and
epidemic?

3. Epidemic disease
▪ Epidemic disease affects many persons
▪ It is locally spread from person to person

4. Pandemic disease
▪ Spread globally
▪ Has higher fatalities comparing to
epidemic diseases

5. Epidemic Flu:
In USA between 2018 and 2019
34,200 deaths
16.5 million infected

6. Can flu be a pandemic disease?
In the 20th century only three times.
In 1918 Spanish flu killed 50 to 100 million
people.
Between 2009 to 2010 Swine Flu, a new strain
of the Spanish flu H1N1, around 700 million to
1.4billion were infected and about 150,000 to
575,000 fatalities.

7. COVID-19 Origin
▪ Wuhan market (China) during 2019 winter
from animal to human
▪ On January 21, 2020 WHO declared the
spread of the virus between humans

8. Why there are many concerns
surrounding the new virous?
COVID-19
Infected: 183,136
Fatalities : 7,173
Seasonal flu worldwide every
year
Infected: 1 billion
Fatalities : 291,000 to 646,000

9. Flu Death rate: 0.1%
COVID-19 Death rate: 3.92%

10. Virus mutation can lead to worst
cases ever seen since Spanish flu
1918 and 1347 plague

11. What do we know about the new
coronavirus?
From the same family as:
▪ (MERS-CoV) responsible for Middle East
Respiratory Syndrome during 2012
▪ (SARS-CoV) that outbreak between 2002 and
2003, responsible for Severe Acute
Respiratory Syndrome

12. The COVID-19 newly named
SARS-CoV-2
▪ Characterized by protein spikes protruding
from their spherical shapes.
▪ These spikes latch onto human cells, then
undergo a structural change that allows the
viral membrane to fuse with the cell
membrane.

13. SARS-CoV-2 new Coronavirus
symptoms
All coronavirus
family
MERS, SARS and
COVID-19 (renamed
SARS-CoV-2) cause

14. All coronavirus family spares children

15. Who at risk?
▪ people with compromised immune systems
▪ elderly people
▪ people with chronic medical conditions
▪ people in group residential settings
▪ people in detention facilities

16. A most efficient method to fight the
spread of the virus is to lock down cities,
but for how long?

17. Major differences:
MERS, SARS and COVID-19 cause Severe Acute
Respiratory Syndrome.
MERS and SARS were easily contained.
Infection happens after 10 days after person shows
symptoms.
COVID-19 patients with mild condition don’t show
any symptoms but still infecting others.

18. ▪ The virus is estimated to last till July.
▪ Virus does not survive temperature above
30oC.
▪ First person to receive coronavirus vaccine in
UAS on Monday the 16th of March 2020

19. "Survival of the healthiest“
Is pandemics the nature practice for selection?
▪ SARS-CoV-2 patients maybe attacked by the
virus after recovery.
▪ Nature elimination of genetic diseases.
