The document explains the differences between pandemics and epidemics, highlighting that pandemics are globally spread and have higher fatalities. It discusses the origin and impact of COVID-19, comparing it to past pandemics like the Spanish flu and swine flu. Additionally, it describes the virus's characteristics, risk groups, and the challenges in controlling its spread through lockdown measures.

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.
