Corona Virus was seen as a disease in the early days. The
disease started spreading slowly. It was declared a pandemic by the WHO (World
Health Organization). After this, the lockdown was declared to prevent this
epidemic. There came a time when the lockdown was imposed all over the world,
and to prevent this epidemic, COVID rules were made by WHO, which was said to
be strictly followed. But what is an epidemic? When does WHO declare any
disease as a pandemic? What to do after declaring a pandemic? What is the
difference between a local epidemic and a pandemic epidemic? Let's know-
1. What is an epidemic?
When a disease spreads
through untouchability, it is called an epidemic. It spreads slowly all over
the world. It isn't easy to control this. Before the coronavirus, diseases like
smallpox, cholera, plague were also declared epidemics. Currently, the coronavirus
is spreading from person to person. How this virus is spreading, the exact
research by scientists has not yet come to the fore. However, research is going
on continuously all over the world on this.
2. When does WHO declare
a pandemic?
At present, there is no
fixed scale for declaring an epidemic but when the disease starts spreading
from one place to another. Gradually it starts spreading from state to country
and country to world, then WHO declares a pandemic. WHO decides whether to
declare a disease a pandemic or not or when to declare it. Swine flu was
declared a pandemic by the WHO in 2009.
3. Difference Between
Epidemic and Local Epidemic
There are two types of
epidemics. These days the infection which is spreading all over the world is
called a pandemic. The Spanish flu spread from 1918 to 1920 was declared a
pandemic. Millions of people died during that time.
In 2014-15, the Ebola
virus spread, which was declared as an epidemic, i.e., local epidemic. Because
this disease was spread only in Liberia and some countries of its South Africa.
4. What to do after
declaring a pandemic?
When a disease is
declared a pandemic, the government and the health system need to be alert. The
health system has to be aware of how to fight the disease, what preparations
have to be made.
CONCLUSION
These days the
coronavirus epidemic is spreading in the form of an untouchable disease all
over the world. It was declared a pandemic by the WHO in March 2020. The
symptoms of this virus have been changing rapidly over time. The wave of corona
came at different times in the world.
So far, two waves of
corona have come in the country of India. There is a possibility of a third
wave in the month of September-October. Until this disease is completely
eradicated, everyone has to wear masks, follow social distancing and keep
washing hands. Vaccination has also started to prevent this epidemic all over
the world, which is giving better results.
