In December 2019, there was a cluster of pneumonia cases in China. Investigations found that it had been caused by a previously unknown virus, now named the 2019 Novel Coronavirus or COVID-19. In this article we’ll take a quick look at what is currently known about the virus. Keep in mind this is often a replacement virus, and what’s known about the virus now might change within the future.
Coronaviruses or COVID-19 are an out sized group of viruses; they contains a core of genetic material surrounded by an envelope of proteins spikes. This gives it the appearance of a crown. Crown in Latin is named ‘Corona’ and that is how these viruses get their name. There are differing types of coronaviruses or COVID-19 that causes respiratory and sometimes gastrointestinal symptoms. Respiratory symptoms can range from the cold to pneumonia and in most of the people,the symptoms tend to be mild. However, there are some types of coronaviruses that can cause severe disease, these include SARS – Coronavirus, identified in China 2003, and MERS – Coronavirus, that was first identified in Saudi Arabia in 2012. The 2019 Coronavirus or COVID-19 was first identified in China 2019.
It initially occurred during a group of individuals with pneumonia, who’d been related to seafood and animal markets in Wuhan. The disease has since spread from the sick to others including relations and healthcare staff. There are many cases at the present and has spread within China and other countries.
So, where did the Coronavirus or COVID-19 come from?
It’s known that the coronaviruses circulate in a range of animals. Sometimes these viruses can make the jump from animals to humans. This is called a spillover and will flow from to a variety of things , like mutations within the virus or increased between humans and animals. For example, MERS from Camels and SARS from civet cats. The animal reservoir of the 2019 coronavirus is not known yet.
How Coronavirus or COVID-19 transmitted?
The exact dynamic of how the virus is transmitted is yet to be determined, in general respiratory is usually transmitted through droplets created when an infected person coughs or sneezes or through something that has been contaminated with the virus. People most in danger of infection from coronavirus are those in close contact with animals, like animal workers and people who are caring for people that are infected with the virus, like relations or healthcare workers.
How does the disease present?(Symptoms)
(Symptoms) Well, from what’s known thus far there might be variety of symptoms starting from mild to severe. There can be fever and respiratory symptoms such as cough and shortness of breath. In more severe cases there’s been pneumonia, kidney failure and death. The mortality rate is not known yet.
How can we tell if someone is infected by Coronavirus or COVID-19?
The infection can be diagnosed with a test known as PCR or Polymerase Chain Reaction. This test identifies the virus based off its genetic fingerprint. There’s currently no known medication for the virus and treatment is supportive care. There is currently no vaccine to protect from the virus. Treatments and vaccines are in development.
How do we prevent transmission of the Coronavirus or COVID-19?
This new virus currently has a limited geographic spread, however there are a number of standard hygiene practices that have been recommended to protect against infection and further spread. These include covering your mouth and nose with a medical mask, tissue or flexed elbow. Avoid close contact with those who are unwell. The appropriate use of masks and personal protective equipment, especially in the health care setting, washing hands regularly with soap and water or alcohol-based hand rub. Actions that can be taken to prevent infection from an animal source include: Avoiding unnecessary contact with animals, washing hands after contact with animals or animal products and ensuring animal products are cooked thoroughly before they’re consumed. It’s important to remain home if you are feeling unwell, but if you’ve got a fever, cough or difficulty of breathing seek medical aid early and share your previous travel history with your health care provider.
