Recently, we heard about virus called ” Novel Coronavirus“. Everybody talking about this virus. so, we write about this article to understand better about Novel Coronavirus.
What is a Coronaviruses?
Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans. They are typically spread through airborne droplets of fluid produced by infected individuals in humans. At the end of 2019, a new type of coronavirus emerged that help to make people sick in China. Now, New Coronavirus named as “COVID-19” by WHO. On March 12, 2020, WHO declared COVID-19 outbreak became “global pandemic“.
At the end of 2019, a new type of coronavirus began making people sick in China. You might hear the virus called COVID-19. Some of the first cases were diagnosed in people who had visited a market selling live seafood and animals.
According to WHO,
Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.
It was discovered and detail described in the 1960s, the coronavirus gets name from a distinctive corona or crown-like shape from the envelope surrounding the particle. Encoding the virus’s make-up is the longest genome of any RNA-based virus – a single strand of nucleic acid roughly 26,000 to 32,000 bases long.
Coronaviruses are zoonotic meaning they are transmitted between animals and human. Previous coronavirus like SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to human. Several known coronaviruses are circulating in animals that have not yet infected humans. Now recently spread coronavirus (COVID-19), scientists believe to virus spread through live animal markets from Wuhan, Hubei Province, China.
How dangerous is the new coronavirus (COVID-19)?
Novel Coronavirus (COVID-19) which is emerged from Wuhan, China in December. Noval Coronavirus (COVID-19) is transmitted more rapidly to humans compared to SARS, though it is less virulent. Scientists believe, one infected individuals can transmitted average 2 to 3 peoples.
Currently, COVID-19 infected more than 1.4 millions peoples confirmed case, more than 290000 recovery case, death case is more than 80000 and also increasing rapidly day by day. It infected more than 190 countries around the world. WHO confirmed the virus’ fatality rate is around 3.4%, but health experts predict it could ultimately be lower as more cases are reported. Most of those who have died, were older age peoples or had other ailments that comprised their immune system much more vulnerable than the young. About 80% of patients have experienced mild symptoms, according to new report from the Chinese Center for Disease Control and Prevention that looked at 72,314 cases. It’s the largest analysis released so far. If we compared to SARS and MERS with COVID-19, SARS fatality rate is 10% and MERS fatality rate is 33%. For comparison, seasonal flu has a mortality rate below 0.1 per cent but it infects so many people that it results in about 400,000 deaths a year worldwide. Spanish flu infected an estimated 500m people and killed 50m worldwide in 1918-19.
How does the virus spread and what is the incubation period?
The virus spread through airborne droplets of fluid produced by infected individuals to other humans. The “incubation period” means the time between catching the virus and beginning to have symptoms of the disease. Most estimates of the incubation period for COVID-19 range from 2-14 days, most commonly around five days but some of the study show upto 28 days.
Symptoms of Novel Corona Virus (COVID-19)
- Dry cough
- Headaches and pains (some patients)
- Nasal congestion
- Runny nose
- Sore throat or diarrhoea (rare)
Prevention from COVID-19
There is currently no vaccine to prevent coronavirus disease (COVID-19).
- Wash your hands frequently with alcohol-based hand rub or soap and water for at least 20 seconds
- Maintain social distancing / Avoid close contact
- Avoid touching eyes, nose and mouth
- Cover nose and mouth when coughing and sneezing with tissue or flexed elbow
- If you have fever, cough and difficulty breathing, seek medical care early
- Avoid direct, unprotected contact with live animals and surfaces in contact with animals
- Avoid eating raw or undercooked animal products and exercise care when handling raw meat, milk or animal organs to avoid cross-contamination with uncooked foods.
