COVID-19 : What is?
Corona virus disease here forthwith referred to as COVID-19, is an infectious disease caused by a newly discovered coronavirus. Coronaviruses are a group of related viruses that cause diseases in mammals and birds. In humans, it causes respiratory infections that can be mild, such as some cases of the common cold , and others that can be fatal, such as SARS, MERS, and COVID-19.
COVID-19 :How? – Inception
In December 2019, a pneumonia outbreak was reported in Wuhan, China. On 31 December 2019, the outbreak was traced to a novel strain of coronavirus, which was given the interim name 2019-nCoV by the World Health Organization (WHO).
As of 25 March 2020, there have been at least 18,883 confirmed deaths and more than 421,792 confirmed cases in the corona virus pneumonia pandemic. The Wuhan strain has been identified as a new strain of Betacoronavirus from group 2B with approximately 70% genetic similarity to the SARS-CoV. The inception of the virus from a bat soup might probably be true as the virus has a 96% similarity to a bat corona virus, so it is widely suspected to originate from bats as well.
COVID-19 : Disease
Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.
COVID-19 cause colds with major symptoms, such as fever, and sore throat from swollen adenoids, occurring primarily in the winter and early spring seasons.
COVID-19, if left untreated can cause pneumonia (either direct viral pneumonia or a secondary bacterial pneumonia) and bronchitis (either direct viral bronchitis or a secondary bacterial bronchitis) which can prove extremely fatal especially for the people having underlying health issues.
COVID-19 : Ways to Prevent
The best way to prevent and slow down transmission is to be well informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol based rub frequently and not touching your face.
The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it’s important that you also practice respiratory etiquette and proper hygiene. At present, there are no specific vaccines or treatments for COVID-19. The doctors are solely depending on our immune system to fight off and kill the virus from within. However, there are many ongoing clinical trials evaluating potential treatments.
COVID-19 : WHO prescribed Steps to Prevent
To prevent infection and to slow transmission of COVID-19, do the following:
- Wash your hands regularly with soap and water, or clean them with alcohol-based hand rub.(the recommended composition of alcohol is at least 60%)
- Maintain at least 1 metre distance between you and people coughing or sneezing.
- Avoid touching your face especially the eyes, nose and mouth.
- Cover your mouth and nose when coughing or sneezing.
- If you happen to catch a cold and/or showing any symptoms for CoVid-19 then wear a mask to prevent further transmission.
- Stay home if you feel unwell.
- Refrain from smoking and other activities that weaken the lungs.
- Practice physical distancing by avoiding unnecessary travel and staying away from large groups of people.
- Kindly make it a habit of trying to greet someone without having any physical contact with him/her.
COVID-19 : Global Pandemic
Growth factor is the factor by which a quantity multiplies itself over time. The formula used is every day’s new cases / new cases on the previous day. For example, a quantity growing by 7% every period (in this case daily) has a growth factor of 1.07.The 2019-nCoV has shown a Reproduction Number(RO) of 2.7 (which implies that the virus can spread to 2.7, roughly 3, people from a single infected person). The virus has shown to have been extremely aggressive in contagion in comparison to its SARS-2003 counterpart. The pandemic has resulted in travel restrictions and nationwide lock downs in several countries.Globally, more than 400,000 people have contracted the virus in 169 countries and regions.More than 18,000 deaths have occurred.The 2020 Summer Olympic Games have officially been postponed.
