Corona Virus

     A new coronavirus designated 2019-nCoV, was identified in Wuhan, the capital of China’s Hubei after people developed pneumonia without a transparent cause, and for which existing treatments weren't effective. The virus has shown evidence of spread between people, with its transmission rate escalating in mid-January 2020 and several numbers of other countries across Europe, North America and especially the Asia-Pacific reporting cases. Its incubation period (time from exposure to onset of symptoms) ranges from 2 to 14 days, but there is evidence that it's going to be contagious during this period and possibly also for several days after recovery. Symptoms include fever, coughing and breathing difficulties, and it can be fatal.

Corona Virus

What Is a Coronavirus?

     Coronavirus is a large family of viruses found in both animals and humans. It is first described intimately within the 1960s, it is known for containing strains that cause potentially deadly diseases in mammals and birds. In humans, they’re typically spread via airborne droplets of fluid produced by infected individuals. The coronavirus gets its name from a distinctive corona or ‘crown’ of sugary-proteins that projects from the envelope surrounding the particle.

Types of Coronavirus

There are mainly four types of coronavirus in the family, named
  • Alphacoronavirus.
  • Betacoronavirus.
  • Gammacoronavirus.
  • Deltacoronavirus.
But recently a new coronavirus designated 2019-nCoV was identified in Wuhan, a city of China. This coronavirus is known as the 2019 Novel Coronavirus.
The first two only infect mammals (bats, pigs, cats, and humans).
Gammacoronavirus mostly infects birds (poultry).
Deltacoronavirus can infect both birds and mammals.
Some rare but notable strains, including Wuhan coronavirus (2019-nCoV), and those responsible for severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS), can cause death in humans. Encoding the virus’s make-up is the longest genome of an RNA-based virus – a single strand of nucleic acid roughly 26,000 to 32,000 bases long.

  • What are the symptoms of coronavirus?

         Coronavirus can give rise to a variety of symptoms in different animals. While some strains cause diarrhea in pigs and in turkeys, most of the time infections are often compared to a bad cold, causing mild to moderate upper respiratory problems such as a runny nose and sore throat.
       There are a couple of lethal exceptions, which have had a devastating impact on livestock and human health around the globe.

    Wuhan coronavirus (2019-nCoV)

    Wuhan coronavirus was first identified in Wuhan city of China in December 2019. This is known as Novel Coronavirus(nCoV) that has not been previously identified in humans. At the time of writing, numbers of infected and the number of death are still on the rise. By Tuesday, the toll in China was more than 420 deaths. 
    The Chinese government has reported 20,438 confirmed cases — roughly 15,000 more than during the SARS outbreak, according to the World Health Organization.

  • How dangerous is it?

    As with other respiratory illnesses, infection with 2019-nCoV can cause mild symptoms including a runny nose, sore throat, cough, and fever. It can be often more severe for some persons and may cause pneumonia or breathing difficulties. More rarely, the disease can be fatal. Older people and people with pre-existing medical conditions (such as diabetes and heart disease) appear to be more vulnerable to becoming severely ill with the virus.

    Severe acute respiratory syndrome (SARS-CoV)

    SARS was first recognized as a distinct strain of coronavirus in 2003. The source of the virus has never been clear, though the first human infections can be traced back to the Chinese province of Guangdong in 2002.
    The virus then became a pandemic, causing more than 8,000 infections of an influenza-like disease in 26 countries with close to 800 deaths.

    The Middle East respiratory syndrome (MERS-CoV)

    MERS was first identified in Saudi Arabia in 2012 in people displaying symptoms of fever, cough, shortness of breath and occasionally gastrointestinal problems such as diarrhea. An animal source for the virus has never been officially confirmed, though evidence points to dromedary camels as a potential reservoir of infection.
    The World Health Organisation has identified around 2,500 cases of infection in 27 countries since initial outbreaks, resulting in nearly 860 deaths.

    How are coronavirus infections spread?

    Coronaviruses usually spread from an infected person to others through
    • The air by coughing and sneezing
    • Close personal contact, such as touching or shaking hands
    • Touching an object or surface with the virus on it, then touching your mouth, nose, or eyes before washing your hands

    What are the symptoms of coronavirus infections?

         The symptoms depend on the type of coronavirus and how serious the infection is. If you have a mild to moderate upper-respiratory infection like the common cold, your symptoms may include
    Some coronaviruses can cause severe symptoms. The infections may turn into bronchitis and pneumonia, which cause symptoms like:
    • Fever, which may be quite high if you've pneumonia
    • Cough with mucus
    • Shortness of breath
    • Chest pain or tightness once you breathe and cough
    Severe infections are more common in people with heart or lung diseases, people with weakened immune systems, infants, and older adults.
