This book describes Pandemics, Diagnosis and Treatment and Related Diseases

Pandemics have been present in the history of the world for a long long time.

A pandemic (from Greek pan "all" and demos "people") is depicted as an epidemic of disease that has spread across a large region, multiple continents, or worldwide.

The term pandemic indicates geographic spread and is used to depict a disease that involves a whole country or the whole world.

Also, influenza pandemics normally do not include the repeat occurrences of seasonal flu.

Current pandemics are HIV, Tuberculosis, malaria and COVID-19.

There have been a number of pandemics throughout history such as smallpox and tuberculosis.

One of the most destructive pandemics was the Black Death which caused the deaths of about 75 - 200 million people in the 14th century.

Some recent pandemics are: HIV, the Spanish flu, 2009 Asian flu pandemic and swine flu H1N1.

In December 2019 the COVID19 pandemic began and is still continuing to spread throughout the world.

As a doctor in a public housing clinic I encountered SARS in 2003, Swine Flu in 2009 and now COVID-19 pandemics which put my medical senses on high alert each time.

However in the 2 earlier pandemics I never have to face a lock down of Singapore (or Circuit Breaker as it is called here).

During the ongoing COVID-19 my clinic is one of the few essential services that continued in spite of closed shops and deserted streets.

It was heart-breaking to see so many people worked from home and wearing masks even though I have gone through the SARS and H1N1 (Swine flu) pandemics.

People in contact with infected persons are advised to be quarantined at home or other places for at least 14 days to prevent the spread of the virus to other healthy persons.

Many small businesses are affected.

Some are closing while others had to let go of their employees.

However the Government is helping by providing a cash payment of $600 for every adult which we have already received.

The Prime ministers and ministers are showing their support for what every Singaporean has lost by taking a pay cut of 3 months.

COVID-19 has been on the minds of every person in the world because it has so much implications on their health (physical or financial).

It is in the mind of every health care worker in the world because they are facing the virus every day.

They may not have fears for themselves but certainly they are concerned about the safety of their family and friends in case they bring a single virus to their family.

The COVID-19 virus occupy the minds of the whole world.

We hear about the success of CHINA and New Zealand in containing the virus while Europe and USA is struggling with increasing cases.

Wearing a mask and safe distancing is important to prevent virus infection while contact tracing helped to find possible asymptomatic as well as symptomatic cases.

At a time like this all countries should cooperate and fight the COVID-19 pandemic instead of fighting among themselves.

The fate of humanity depends on the responses of all of us.

Like in the movie Contagion, the production of a vaccine against COVID-19 is the best way to fight and cure this disease.

It is the best way to fight this disease and return to a more hygienic way of life.

It is the best way to live a life where the world learns to cooperate with each other so that we can continue to visit each other and care for each other.

No man is an island especially in the post-COVID-10 world!

I wish every one in this world the best and hope to see every one of...
