What is a Virus?
Let us first understand what is a Virus? Influenza, Bird flu, Polio, swine flu, dengue fever, etc. are among the diseases caused by Viruses.
These are pathogens that affect plants and animals. Viruses are not cells and cannot replicate independently unless they are inside the host body. They cannot be seen under a light microscope as they are too small.
In Live hosts, viruses reproduce and use the metabolic machinery of the host. Also, in the presence of genetic material either in the form of DNA or RNA they undergo replication.
Viruses are generally classified on the basis of core and coat. The core is comprised of Genome whereas, Coat is referred to as capsid and in some cases, it is protected by an additional layer called the envelope.
An enveloped virus creates much resistance against the host’s immune system.
What is Coronavirus?
Coronavirus is among the big family of viruses and they mainly affect the respiratory system. The name coronavirus is derived from corona Latin called crown, which tells about the attribute of virus i.e. enveloped. They have single-stranded RNA as a genome, which poses a big challenge for scientists in developing its vaccine.
In the year 2002-2003 SARS (severe acute respiratory syndrome) outbreak affected many people and the Case Fatality rate (CFR) was 9.6% and MERS (Middle-East Respiratory Syndrome Coronavirus) in the year 2012 had CFR of 34.4%. Both are forms of coronavirus and killed 774 and 860 people respectively. The CFR for novel Coronavirus called Covid-19 is estimated to be 2% but it’s just an estimate, as it can go up or down once the actual figures are revealed from infected areas.
The Latest Outbreak has its origin in Wuhan, China where people nearby seafood markets were the first reported victims of this virus. This later has spread to a large population affecting thousands and killing many. Apart from China, Japan has the highest rate of infected people from Coronavirus along with South Korea, Italy, Iran, Singapore, Hong Kong, Malaysia, USA, Germany, France, UAE, etc.
World Health Organization (WHO) has declared Covid-19 a public health emergency and not a ‘pandemic’ as its outbreak outside China is not an unexpected development. Pandemic is a worldwide spread of disease.
What are the Symptoms?
The Covid-19 coronavirus cause pneumonia and the symptoms associated with it are coughs, fatigue, muscle pain, diarrhea, nausea, fever and difficulty in breathing. Antibiotics and antiviral drugs are of no use against this viral pneumonia. If you have a strong immune system! Don’t worry you are safe, as the victims of this virus are those with a weak immune system and history of respiratory diseases. This virus is transmitted from human to human so avoid going to places infected by this virus.

How it Affect Your Body?
Coronavirus affects your respiratory system. The early symptoms include fever and cough and if your lungs become inflamed it causes pneumonia. If this situation turns severe it turns into cytokine storm, when the immune system goes into overdrive which overwhelms the body with cells and proteins and ultimately damages organs.
The virus is nurtured in your body for days without showing any symptoms of illness; it multiplies in the respiratory tract. Those with cardiovascular diseases, diabetics, weak health are more vulnerable to this virus. Overall, in 82% of the cases, the situation remains mild and nearly 2% of victims of the virus died in severe cases. People with mild disease may take two weeks to recover while those with severe disease may take up to six weeks to come around. So far the highest percentage of people who died due to this disease are in their 60s or older.
