In recent times Corona Virus Disease is making headlines. It is reported that many people globally were adversely affected by the disease and there were many deaths because of the disease. Many patients suffering from the disease are dying from the disease. What is a disease? Novel Corona Virus Disease was first detected in China and now it has been detected in many parts of the world.
Very recently, on 30th January 2020, WHO or World Health Organization has declared that the disease has resulted in a public health emergency. According to WHO COVID-19 or the Corona, Virus Disease is a pandemic.
The genesis of the virus and how it spreads
Coronaviruses are common in various animal species like cattle, camel, bats, and cats. Animal coronaviruses rarely affect people and then spread among them. The coronavirus that is causing disease among humans is also known as the SARS-CoV-2. It is a type of beta coronavirus. This virus is similar in type to that of the SARS-CoV and the MERS-CoV. These viruses have their genesis in bats.
Since the outbreak of the Corona Virus Disease the corresponding virus that causes the disease is spreading fast among humans. It is reported that the virus is spreading through food suggesting animal to person spread. Over a period of time, it is understood that the virus spreads from one person to another suggesting person to person spread. Besides, community spread implies that a large number of global populace is affected by the Corona Virus Disease.
The severity of the Disease
Not much is known about the virus. People suffering from the disease reported mild symptoms, sometimes no symptoms and at other times severe symptoms. Those where the symptoms are severe have reported deaths. Aged people, as well as people of all ages with severe and chronic medical conditions like lung disease, heart disease, and diabetes, are a greater risk of developing COVID-19 illness.
COVID-19 has now declared a Pandemic
When a disease spreads on a global scale then it is referred to as a pandemic. A pandemic occurs when there is an emergence of a new virus, when a virus infects people and when it spreads between people at a rapid pace. With COVID-19 there is little or no pre-existing immunity against the virus and therefore it is spreading worldwide. The virus COVID-19 is infecting as well as spreading rapidly from one person to another. There has been a significant rise in COVID-19 cases worldwide. Community spread of the disease is detected in many counties across the world.
Risk of exposure to the Disease
Though in the beginning, the risk of being exposed to the virus is low but with the outbreak of the disease the risk increases. Wherever coronavirus disease has occurred, the risk of exposure to the disease is high.
Health care professionals caring for patients suffering from the disease are at an elevated risk of getting exposed to the disease. Travelers who are returning from affected countries are also at a higher risk of getting exposed to the disease.
Risk of Severe Illness
The trends that are associated with COVID-19 suggest that there is a section of the population who are at an elevated risk of falling sick because of the disease. This includes aged adults who are suffering from severe medical conditions like diabetes, heart disease, lung disease. The World Health Organization has developed guidance to aid in risk assessment as well as risk management of people who remained exposed to COVID-19.
What May Happen Because of the Spread of the Virus?
In the days to come more and more people worldwide would be adversely affected by the Corona Virus. This is because the virus is spreading fast and there is no vaccination as yet to counter the disease. Widespread transmission of the Corona Virus Disease will result in more and more affected people needing medical help. Schools, workplaces, child care centers are expected to experience absenteeism. There can be the postponement of mass gatherings of people. There can be an overload of public health systems. More and more people may become hospitalized.
More and more deaths may be reported. It is expected that in due course of time, with the progress of the disease, critical infrastructure like law enforcement, sectors in the transportation industry, emergency medical services can get adversely affected. At this point in time, there are no vaccines to protect against the disease. Non-pharmaceutical approaches to prevent the cause of the disease are the order of the day to delay the spread of the COVID-19 and reduce the impact caused by the Corona Virus Disease.
