12th of March WHO announced coronavirus or COVID 19 as a “Pandemic”. What is it “pandemic”? What does it mean? And when it can be announced? Before starting to know this word, let’s know what is it “epidemic”? If a particular problem or new virus, seriously affects a lot of people in society in a short period and if it passes quickly from human to human then this is an epidemic. An epidemic is a Greek word, epi – means “upon” or “above”, demos – “people”. If one illness that appeared in one country spreads to other countries, it called a pandemic. So, if an epidemic spreads to other countries, then it is called a pandemic. Let me explain. An epidemic when one illness spreads within the country, pandemic when this illness spreads in the world. Pandemic is a Greek word that means “all people”. Also, pandemic situations happened in history and were reasons for changed history. For example, the plague happened 3 times in history and each time was the reason for the death of a million people. The first pandemic was a Justinian pandemic. It started in Egypt and destroyed a lot of countries. This disease spreads from rats/mice to people and lasts approx.60 years. The worst history of the pandemic was during 542 and only in Constantinople, Istanbul with its current name, the daily death number was thousands of people. One of the famous writers of that epoch in Byzantium left this kind of piece of evidence. It doesn’t matter where you are, on the island, in the cave, at the top of the mountain, there was no escape from the plague for the human being. The second plague “Black Death” started in Asian countries, spread to the rest of the world and killed approx. 25 million people. The third plague pandemic started in 1855 in Chinese province Yunnan and spread to the rest of the world with trade roads. More stories of the pandemic in history. One of them is smallpox. A big percentage of people who infected smallpox, dead due to a virus. People who recovered from this disease, couldn’t see or they had problems with the skin. Smallpox killed 1/3 population only in Japan. Cholera. One of the most spread and deadly illnesses in the 19th century. Was the reason for the death of millions of people. Pandemic started in 1816 in Bengal. Spread to India, China and rest of the world and killed millions of people. Cholera happened 7 times in history. Spanish flu which I mentioned in the last video also was pandemic. If you didn’t watch it yet, check it out. The last pandemic was in 2009. It called the Swine flu or H1N1 influenza virus. During 1 year approx. 1.4 billion people infected with this virus. During this pandemic approx.575 thousand people died due to the virus. Cases for COVID-19 for all of the world so far: 190,535 and death: 7,519 people. Recovered: 80,648. COVID-19 has been seen in older people, too and very dangerous to them. This is the death rate from this virus according to the age and their percentage. I explained to you in the last video, how you can infect the virus. Let’ remember it. If someone who ill will sneeze next to you or if you will handshake with that person and without washing, if you will touch your face with hands you might infect, too. The virus lives only in the living cell but they can survive during 2-3 hours without the living cell. That is why if you will touch infected place and touch your face you will be infected, too. The virus after infection will appear during 2-14 days. All viruses have genetic material. DNA & RNA COVID-19 has RNA and enough for spread. If we look for examples to viruses with RNA Ebola SARS Flu Hepatit C Measles When the tip of the COVID-19 touches the cell and if can open the cell and finds the correct cell can enter to it. Cells use their DNA and synthesize an important protein for the human body using ribosomes. But COVID-19 breaks this system after entering the cell and produces as much protein as needed. In the sequel produces viruses in the human body and kills healthy cells. After killing the healthy cell, viruses looking for new cells. If you have a strong immune system during several days your body understands that something different happens and starting fights with viruses. When your immune system fights with viruses you will feel weakness, increased fever, shortness of breath and sweating starts. Because of immune system gives all energy to fight with viruses, can’t do normal functions. Increased fewer can kill viruses in the human body and increases saliva which doesn’t let stay the virus on the cells. While protecting themselves immune system can make weak the human body. During this period human should stay alive. How can we protect ourselves from COVID-19? Actually, it is not too difficult. Don’t go to overcrowded places; even if you’ll go don’t touch your face; often disinfect your hands; don’t greet with handshaking; wash your hands at least 20 sec. For a strong immune system eat only healthy food. Eg., fruits & vegetables. Your age might be small. You might not afraid of the virus. You can think, the virus is dangerous for older people. But don’t forget. You can infect older people. If you find symptoms of COVID-19, wear mask and go to the HOSPITAL. Due to the pandemic, governments can quarantine their countries. Eg., Italy in the quarantine now. people are not allowed to go outside. Some countries stopped communication for a while. It should happen. Because there are not any vaccinations for the virus. Decreasing communications is a solution not to spread the virus. One more reminder. Do not trust in every news. Listen to the news from local health agencies or WHO. Don’t get “Panic” word from “Pandemic” As mentioned in the previous video, don’t panic. Why? In some countries due to panic people fighting in markets and other places. Panicking is not nice.
