It’s no longer news that the Coronavirus outbreak has caused a lot of panic in the world especially for the Chinses who seem to be suffering more from the deadly impact of the virus.
it’s very necessary that you understand the ins and outs of these threat and how best to protected yourself against it especially now that it seems to be spreading to all the corners of the earth. In this article, I’m going to give you all the details you need to know about the deadly virus and how best to protect your family and loved ones against it.
The name CORONA came from a Latin Word Corona which means Crown or Halo. The virus was named Corona virus because when viewed under an electron microscope, it looked like a Solar Corona.
Coronaviruses are a group of large enveloped RNA viruses under the Coronaviridae and Roniviridae. Coronaviruses are further classified into four main genera: Alpha-, Beta-, Gamma-, and Delta coronaviruses.
The coronaviruses can infect a large variety of hosts ranging from Avian, swine, and human. The Human Coronaviruses (HCoVs) are identified to being either in the Alpha- or Beta coronaviruses genera.
Human Coronaviruses (HCoVs) are a large family of viruses that are associated with multiple respiratory diseases of varying severity including common cold, Pneumonia and Bronchiolitis. The Human Coronaviruses Are Zoonotic. This means they are transmitted from animal to people. Coronaviruses are one of the most rapidly evolving viruses due to the high rate of its Genomic and Nucleotide substitutions and combinations through frequent mixing and crossing of species barriers.
Report has over the years shown that they are many types of the Coronavirus. In fact, most people get infected at some point in their lives and majority of this virus infection are generally harmless or with very minor effect on humans. Also research has also proven that several known Coronaviruses are circulating in animals that have not yet infected humans.
Before the discovery of The Middle East Respiratory Syndrome (MERS-COV) and Severe Acute Respiratory Syndrome (SARS-COV). 14 years ago, the other four viruses have been globally circulated in the human population and has been the major cause of common cold infections in humans.
The two deadliest among the coronaviruses family includes The Severe Acute Respiratory Syndrome (SARS-CoV) which was first discovered in Guangdong, China in 2002-2003 as an unusual pneumonia which later developed into life threatening respiratory failure in many of the cases. The virus spread through 29 countries infecting approximately 8000 people and killing about 800 of them.
The second, the Middle East Respiratory Syndrome (MERS-CoV) this deadly type of coronavirus appeared as an epidemic in Saudi Arabia in the year 2012. It has similar symptoms as SARS-CoV with a much higher death rate at about 34% unlike SARS-CoV with a death rate of about 10%. The MERS-CoV remained within the middle east region
It was confirmed that the SAR-CoV came through Bats and then to Palm Civets from where it was transferred to humans. While Dromedary Camels are said to be the major animal source of the MERS-CoV infection in people.
Just when we thought we have heard the worst about Corona virus, cases of an illness similar to that of the SARS-CoV and MERS-CoV viruses where reported in the Chinese central city Wuhan in early December 2019. On January 7, the Chinese authorities confirmed that the illness was a new type of Corona virus which was called COVID-19 (Coronavirus disease 2019).
It was reported to be a new type of coronavirus that has never been found in humans before and its origin was traced down to a large seafood and animal market in Wuhan China.
The new coronavirus COVID-19 has been declared as a public health emergency by the world health organization as the outbreak has spread across China to other countries around the world infecting more people that the SARS-CoV did.
More than 90,000 cases of the infection have been reported worldwide and about 3110 deaths most of which are in Mainland China this shows that the new COVID-19 has by far surpassed the case of the 2002-2003 SARS-CoV outbreak in China which killed about 9% of those infected nearly 800 people worldwide and more than 300 in China alone. Though this new COVID-19 virus is more widely spread than SARS-CoV, its mortality rate is considerably low at approximately 2%
SIGNS AND SYMPTOMS.
According to the World Health Organization, signs of the infection of the new COVID-19 includes fever, cough, shortness of breath and breathing difficulties, respiratory syndromes, kidney failure and even death. And the amount of time it takes for the signs to show in an infected person rages from 1 to 14 days as most people show the symptoms within 4, 5 to 6 days. However, some of the infected patients do not display any symptom at all despite having the virus in their system.
The animal origin of the COVID-19 virus has not been confirmed but on February 7th, Chinese researchers said that it might have spread from infected animal’s species to humans through illegal trafficking of animals like Pangolin, bats and Snakes in the Wuhan central Market.
It is said that Coronaviruses replicate their RNA Genomes using enzymes called RNA-Dependent, RNA POLYMERASES. Which are prone to errors. But the Gnomic analysis of the new COVID-19 suggest that its mutation is very slow hence reducing the chance of it becoming more deadly.
There are currently no vaccines or specific drugs for the treatment of coronaviruses. But scientist around the globe are racing to develop a vaccine for it and have reported that one is most likely going to be available by 2021.
Standard recommendation for the prevention of the spread of this viruses includes regular hand washing, covering mouth and nose when coughing and sneezing, thoroughly cooking meat and eggs, avoiding close contact with anyone showing the symptoms.
On the 30th of January 2020, the World Health Organization (WHO) declared the COVID-19 virus a global health emergency.
This was done after the first case of human to human infection was confirmed outside of China. This emergency is called THE INTERNATIONAL HEALTH ALERT which is under the guidance of the United Nations Health Agency. It is a call to countries around the world to coordinate their response against a particular global health challenge. In this case the covid-19 Coronavirus.
According to Aljazeera, they have been 5 international health calls since 2005 when the declaration was formalized. The Swine flu in 2009, Polio in 2014, Ebola in 2014, the Zika in 2016 and then Ebola again in 2019.
