What is Coronavirus or COVID-19? What are the symptoms? and How do I protect Myself?



Coronavirus disease (COVID-19) is a recentely discovered coronavirus-caused infectious disease. Most people infected with the COVID-19 virus will develop mild to moderate respiratory disease and recover without any special treatment being needed. Older people and those with underlying health conditions such as cardiovascular disease, diabetes, chronic respiratory disease and cancer are more likely to experience serious illness.


Being well educated about the COVID-19 virus, the illness it causes and how it spreads is the best way to avoid and slow down transmission. Protect yourself and others from contamination by washing your hands or regularly using a rub dependent on alcohol, and not touching your nose.


How easily the virus spreads?


How easily a virus spreads can differ from person to person. Some viruses are extremely infectious (quickly distributed), like measles, while others don't distributed as quickly. Another aspect is that the spread is continued, constantly spreading without stopping. For certain affected geographic areas, the virus that causes COVID-19 appears to spread quickly and sustainably within the population ("population spread").



Where do coronaviruses come from?


Bats are regarded as natural hosts of these viruses, but many other animal species are also considered to be a vector. For example, the Middle East Coronavirus Respiratory Syndrome (MERS-CoV) is transmitted from camels to humans, and the Extreme Acute Respiratory Syndrome Coronavirus-1 (SARS-CoV-1) is transmitted from civet cats to humans.


Is this coronavirus(covid-19) different from SARS?



SARS stands for severe acute respiratory syndrome.In 2003, an outbreak of SARS started in China and spread to other countries before ending in 2004.The virus that causes COVID-19 is similar to the one that caused the 2003 SARS outbreak: both are types of coronaviruses.Much is still unknown, but COVID-19 seems to spread faster than the 2003 SARS and also may cause less severe illness.

The rapid spread of the COVID-19-causing virus has caused concern around the world. A rapidly spreading coronavirus epidemic has been declared a pandemic by the World Health Organization (WHO) and several countries are struggling with an rise in reported cases. The Centers for Disease Control and Prevention (CDC) is urging people in the US to be prepared for everyday life changes that would be expected if the coronavirus spreads within populations.


Person-to-person spread


1. Between people who are in close contact with one another (within about 6 feet).


2. Through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.


Spread from contact with contaminated surfaces or objects

A person might be able to get COVID-19 by touching a surface or object that has the virus on it, and

then touching their own mouth, nose, or probably eyes, but this is not thought to be the primary way the virus spreads.


What are the coronavirus symptoms?



The lungs are contaminated with coronavirus. The symptoms start with a fever followed by a

dry cough which can lead to problems with breathing. This is a fresh, persistent cough which involves coughing for more than an hour, or getting three or more episodes of coughing in 24 hours (if you normally have a cough, it could be worse than usual). It takes an average of five days to begin displaying the symptoms, scientists said, but some people will experience symptoms even longer than this. The World Health Organization (WHO) currently states the time of incubation lasts up to 14 days.


People may experience:

1. Cough

2. Fever

3. Tiredness

4. Difficulty breathing (severe cases)





How many people have been affected?



In January, China's national health commission confirmed the transfer of human to human beings.

According to the Johns Hopkins University Center for Systems Science and Engineering, as of March 30 more than 720,000 people were infected in more than 150 countries.


There are more than 34,000 deaths worldwide. In mainland China, where the coronavirus was first reported in the city of Wuhan, just over 3,000 of those deaths happened. Nevertheless, with more than 10,000 casualties, Italy was hit hardest and Spain has seen more than 6,800 deaths. There are more confirmed cases in the US now than any other country. Many of those who have died had underlying health conditions, which the coronavirus complicated. Over 150,000 people are reported recovering from coronavirus.


How is COVID-19 diagnosed?


Diagnosis may be difficult with only a physical exam because mild cases of COVID-19 may appear similar to the flu or a bad cold.The diagnosis can be confirmed by a laboratory examination.



How is COVID-19 treated?


There is no clear cure for the virus as of now. Patients who are ill from COVID-19 should be provided with interventions of support: those that alleviate symptoms. Numerous treatment options can exist for serious cases like research drugs and therapeutics. There are no specific treatments for coronaviruses, but symptoms can be treated.


Does COVID-19 cause death?

As of 30 March 2020, COVID-19 was attributed to 34,686 deaths. Yet 154,673 people have recovered from the disease. This knowledge comes from the Global Case Map of Coronavirus COVID-19 developed by the Johns Hopkins Center for Systems Science and Engineering


Why is this worse than normal influenza, and how worried are the experts?



We don't know exactly how serious the current coronavirus is, and we won't know until more evidence comes in, but mortality rate rates have ranged from just below 1 percent in young people to over 3 percent for those who are elderly or have underlying health problems. Usually, seasonal flu has a mortality rate below 1 per cent and is estimated to cause about 400,000 deaths globally every year.

Sars had more than 10 per cent death rate. Another unknown factor is just how contagious the coronavirus is. A key distinction is that, unlike measles, there is no current coronavirus vaccine, which ensures that susceptible members of the population the elderly or those with chronic respiratory or immune issues have more trouble protecting themselves. Hand-washing and avoiding other people if you feel unwell are important.



Can someone spread the virus without being sick?


1.People are thought to be most contagious when they are most symptomatic (the sickest).


2. Some spread might be possible before people show symptoms; there have been reports of this occurring with this new coronavirus, but this is not thought to be the main way the virus spreads.



How do I protect myself From Coronavirus?



1.The best thing is frequent and thorough washing of the hands, preferably with water and soap.




2. Coronavirus spreads out into the air when an infected person coughs small droplets-packed with the virus. They may be breathed in, or cause an infection if you reach a surface on which they fell, then your eyes, nose or mouth. So it is important to coughing and sneezing into tissues, not touching your

face with unwashed hands, and avoiding close contact with infected people to limit spread.



3. Maintain social distancing



When someone coughs or sneezes they spray tiny liquid droplets from their nose or mouth which may contain virus. When you're too close, you can breathe in droplets, like the COVID-19 virus, if you have the disease on the person coughing.
