We give thanks to the almighty god for his blessings and grace so that i can finish this paper well. This paper contains the danger of a world famous virus epidemic namely corona or COVID – 19 Corona virus has claimed many lives through out the world, and the goverment has also many policies so that entire community is not affected by this virus out break. I also thank to the Mrs. Inggrid laurensi Simanungkalit as teacher in English subject for providing systematic work in completing this paper. I am also grateful for the sources that helped me in compling this paper. Hopefully with this paper i can help my friends who want to make papers. Maybe that’s all i can say if there are mistakes in the paper later i hope my friend can forgive me. Thank you TABLE OF CONTENTS Preface…………………………………………………………………..

CHAPTER I Introduction 1.1 Background of the paper Covid began in late 2019 when someone contracted the corona virus from animals traded at the seafood market in Huanan, Wuhan city, Hubei Province, China The story then developed into a heartbreaking tragedy in the history of humanity in the kiwari era. Starting for an infection in wuhan, Covid – 19 has now spread throughout the world and killed nearly 80.000 people. 1.2 Purpose of the paper •To find out the dangers of the corona virus transmission •To find out the effect caused by the corona virus 1.3 Problem Formulation •Why corona virus so dangerous? •What is Coronna virus ( COVID – 19 ) CHAPTER II Teory and discusion 2.1 What is Corona Virus or COVID – 19 ? Corona Virus is a group of viruses that can causes disease in animals or humans. Several types of Corona Virus are known to cause respiratory infections in humans ranging from cold coughs to more serious ones such as Middle East Respiratory Syndrome ( MERS ) and Severe Acute Respiratory Syndrome ( SARS ). A new type of Corona virus has been found causes COVID – 19 COVID – 19 is an infectious disease causes by a newly discovered type of corona virus. This is a new virus disease that were not known before the outbreak in Wuhan, China, in December 2019. The most common symptoms of CoronaVirus are fever, and dry cough. Some patients may experience pain and ache, nasal congestion, runnynose, sore throat or diarrhea. Symptoms experienced are usually mild and appear gradually. Some infected people do not show any symptoms and still fell healty. Most around 80% infected people recover without the need for special treatment. About 1 in 6 people who are infected with COVID – 19 suffer from severe pain and dificulty breathing. Elderly people and people with pre-existing medical conditions such as high blood pressure, heart problems or diabetes, are more likely to experience more serious iilness. Those who have a fever, cough and difficult breathing should seek medical help. People can get COVID- 19 from oter people who have contracted this virus. Covid – 19 can spread from person to person throught sparks from the nose or mouth that come out when a person infected with covid – 19 coughs or exhales. These sparks then fall on nearby objects and surfaces. People whou touch the object or surfaces and then their eyes, nose, mouth, can be infected with Coronavirus. Transmission of COVID-19 can also occur if people inhale a spark that comes out of cough or breath of a person infected with coronavirus. Therefore, it is important for us to keep more than 1 meter from people who are sick. Who continues to review the development of research on how to spread CoronaVirus and will present the latest findings. 2.2Where did the CoronaVirus come from? At the begining of its appearance, the rumor circulated that the SARS-CoV-2 CoronaVirus originated from animals, namely bats, and later, it was also rumored to emerge from the palm. However, not only that. Had also been rumored, this one virus is man- made. The latest news has become a speculation that absorbs the attention of the global community, including in Indonesia. Kristian Anderson PhD, Associate Professor of immunology and Microbiology at Scripps Research, said they compared available genome sequence data for known CoronaVirus strains. Researchers led by Shan-LuLiu at Ohio State University said there was no credible evidence that the virus was genetically created. So, according to him, they had sorted the virus genome. CoronaVirus is a large family of viruses that can cause disease with a wide severity. Meanwhile, researchers have sequenced the viral genome, and compared it with the SARS and MARS viruses According to Shan-LuLiu SARS and MERS came from bats. So , it is not possible Corona is a men-made virus created in the laboratory. Researchers believe the corona virus originates from nature and is not man made. 2.3How to prevent Corona Virus 1.Wash your hand properly is the simplest but effective way to prevent the spread of the Corona Virus. Wash your hand with running water and soap, for at least 20 seconds, make sure all parts of the hand are washed throughly, including the back of the hand, wrist, between the fingers, and nails. After that, dry your hands using a tissue, clean towel, or a hand dryer. If you are a computer worker on public transportation, it will be difficult to find water and soap. You can clean your hand with hand sanitizer. Use hand sanitizer products with an alcohol content of at least 60% to be moe effective at disinfecting germs Wash your hand regulary, especially before and after using the toilet, after touching animals, taking out the trash, and after coughing or sneezing. Washing also important before breastfeeding a baby or expressing milk. 2.Many people use a cloth mast to prevent Corona Virus infection, even though the mask is not necessarily effective. In general, there are two types of masks that can use to prevent the transmission of Corona Virus, namely surgical mask and N95 mask Surgical mask or surgical mask are disposable mask that are commonly used. This mask is easy to find, the price is affordable, and comfortable to wear, so many people use this mask when they are on their daily activities. The correct way to use a surgical mask is that the colored side of the mask should face outward, while the white inner side faces the face and covers the chin, nose and mouth. The white side is made of material that can absorb dirt and filter germs from the air.
