In the history of mankind, we have never seen such a pandemic that can stop the functioning of the whole world. Have any of you ever imagined that the entire world will suffer the same problem at once?
2020 will be marked as a year of suffering; lost lives and livelihood, and many more other things in history. It will also be remembered for the courage and bravery of people who fought this Coronavirus and won against it. Also, it will remind people about the unity that came along with this pandemic, that gave us the strength to wait for the silver lining.
Basic Information about Coronavirus Outbreak
Let’s start from the basic definition and how it originated?
The official name announced by ICTV Covid-19 is “severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)” on 11 February 2020. It is a deadly communicable disease which shows varied symptoms, from mild fever to severe breathing problems. It originated from a lab in Wuhan City, China in December 2019.
What’s the Coronavirus mortality rate? Difference between Coronavirus vs Flu Symptoms
Do you know what makes it different from any other flu? The R nought factor, i.e, the virus’s reproductive number. In simpler terms, it tells how many people can get infected from one coronavirus infected patient. In this respiratory disease case, the R nought factor is 2.5 (on an average of all the countries). For India, it is between 1.5 and 4, which is quite high. There is no proven theory that suggests that a person gets immune from Covid-19 after once infected.
Whereas, simple influenza or cold cough spreads at R nought of 1, and is sometimes beaten by the strong immunity of people. Also, there is a vaccine/verified medication is available to treat these.
In order to control the widespread of this pandemic, the government of different countries has announced the lockdown for a specific number of days. This has happened for the very first time in the history of human civilization that 90% of the total population is under lockdown. This enormous measure will have a drastic impact on the economy.
Can Herd Immunity save us from this pandemic?
How does Coronavirus spread? Coronavirus Structure
The virus is spread when one person coughs or sneezes, and the water droplets come in the touch with another person. Many reports also suggested that it can also transmit through air particles, but that study is still not confirmed yet. When an infected person coughs or sneezes, tiny water droplets, containing the virus, travel in the air up to 3-4 metre (some study suggests up to 8 metres) before it settles onto a surface or human body. As we know, a virus needs a host (human body) to keep itself alive. But the Coronavirus can survive without a host on the various surfaces like plastic, steel for 2 – 24 hours depending upon the surface and the climatic condition.
In the initial phase of this pandemic, it was suspected that coronavirus might not survive in the hot and humid climatic conditions. The South Asian, African countries might not get impacted much from this deadly virus. According to virologists, this virus has a mutation behaviour, meaning the virus can adapt to a situation or host environment and make itself stronger. As per one of the studies, it was suggested the virus carriers (patients) can spread more in lower temperate areas. Thus, some of the countries adopted the measure to use only non AC rooms, vehicles to make the virus hostile.
Coronavirus Early Symptoms? Coronavirus vs Flu Symptoms
The virus takes 4-14 days to show any symptoms like fever, body ache. Recently, there are asymptomatic cases coming up that makes it more difficult to detect. But, the patient can infect others from day 1, thus increases the R nought factor to 2.5. The mortality rate is also high, nearly 3-4% in highly infected countries. Many people with no travel history are getting infected due to community transmission.
