What is coronavirus? Know more about coronavirus

In 2020, an outbreak of a coronavirus (officially known as – COVID-19) in China killed around 5000+ people across the world and infected over 98000+. The virus has spread to over 100 countries, including India. What is coronavirus? Know more about corona virus.
Coronaviruses are a large group of viruses that’s common among animals. In rare cases, they can be transferred  from animals to human body. The spikes protruding from the virus’s membrane look like the sun’s corona. It is from this that the virus called  ‘coronavirus’. It causes effected  of the respiratory tract, ranging from the common cold to severe conditions like SARS. According to the WHO (World Health Organisation), a novel coronavirus (nCoV) is a new strain that can not  previously identified in humans.
What is the difference between Coronavirus and COVID-19
COVID-19 is the disease caused by the novel coronavirus, which originated from China’s Wuhan city. On February, World Health Organisation (WHO) named the novel coronavirus “COVID-19”. “Co” stands for “corona”, “vi” for “virus” and “d” for “disease”, while “19” was for the year, as the outbreak was first identified on 31/12/2019.
  • “Viruses are named based on their genetic structure to facilitate the development of diagnostic tests, vaccines and medicines.”
  • According to the WHO, “there are different procedures, and purposes, for naming viruses and diseases.
  • This particular virus was named “severe acute respiratory coronavirus 2” – or SARS-CoV-2.
  • Viruses are named by the International Committee on Taxonomy of Viruses (ICTV).
The WHO says that “from a risk communications perspective, using the name SARS can have unintended consequences in terms of creating unnecessary fear for some populations, especially in Asia which was worst affected by the SARS outbreak in 2003”.
Hence, the name ‘Covid-19 virus” was given.
Symptoms of coronavirus
Coronavirus can make people sick, usually with a mild to moderate upper respiratory tract illness, similar to a common cold. Some of the symptoms are
  • Runny nose
  • A general feeling of being unwell
  • Headache
  • Sore throat
  • Fever
  • Cough
In case someone is facing lower-respiratory tract illnesses, such as pneumonia or bronchitis, they must seek professional health immediately.
Who is more likely to be a victim coronavirus?
People with a weakened immune system, cardiopulmonary disease, infants, and older adults are more likely to be affected by a coronavirus.
How do you catch coronavirus?
This implies that they are passed on between animals and human. When Severe Acute Respiratory Syndrome (CoV-SARS) sickened 1000+ people around the world & killed approx 700 during a 2003 outbreak, investigations found that it was transferred  from civet cats to humans. CoV-SARS was comes in humans from camels. There are several known corona viruses are circulating in animals that’s not yet infected humans body. On -07/01/2020 Chinese authorities identified corona virus (2019-nCoV) And The  causative virus behind cases of pneumonia of un-known cause. This novel corona virus has not been previously identified in humans body, hence experts say its too early to figure out the exact cause of the Effected .
Will the corona virus spread through cough or sex?
Corona virus is mostly contagious. The disease can spread one person to other person through small droplets from the mouth & nose  In which spread when a person exhales & coughs. These droplets land on  the objects & surfaces around the person. Other people then catch the virus via  touching these objects and  surfaces, then touching your nose eyes,  or mouth. People can also fall victim to virus even if they breathe in droplets from a person infected who coughs out or exhales droplets.
Does coronavirus cause death? How dangerous is corona virus? 
The infamous Severe Acute Respiratory Syndrome (SARS) causes even more severe symptoms. . The death rate with SARS was higher, with older people being the most vulnerable. Along with respiratory problems, it also causes diarrhoea, shortness of breath, fatigue and kidney failure
which was first reported in the Middle East, causes severe respiratory problems. Four out of every 10 patients infected with MERS died in 2012. A few corona viruses are known to be deadly. MERS  (Middle East Respiratory Syndrome),
The new virus (COVID-19) claimed over 3,000 lives and over 100000+  people were diagnosed positive.
How is corona virus diagnosed?
Doctors may recommend the patient to undergo tests on respiratory specimens and serum to detect corona viruses. If anyone experiences the symptoms, they must inform their doctor about recent travel or contact with animals.
Is there a vaccine for corona virus?
There is no specific treatment for corona virus, and no vaccine to prevent it.
How contagious is corona virus?
  • Touching hands of a person that has the virus can pass the virus from one person to another
  • Corona viruses are highly contagious. Coughing and sneezing without covering the mouth can spread the virus
  • A corona virus may spread through contact with face.
  • Making contact with an object that has the virus and then touching your nose, eyes, or mouth can infect a person
Corona virus and pregnancy
In pregnant women, the severe versions of SARS & MERS corona viruses were found to be severe. According to reports, women who suffered from severe versions of corona viruses had stillbirth.
What are the precautions for Coronavirus?
  • Avoid touching your eyes, nose, or mouth with unclean hands
  • Wash your hands thoroughly with soap
  • Avoid close contact with people who are sick
  • Avoid public gatherings

 

 

About Coronavirus what is Coronavirus

  • Cause

Coronavirus coronavirus (Coronavirus-CoV) – virus identified in 2019. Coronavirus-CoV is thought to be an animal virus from an as-yet-uncertain animal reservoir, perhaps bats, that spread to other animals (civet cats) and first infected humans in the Guangdong province of southern China in 2019. 

  • Transmission

An epidemic of Coronavirus affected 100+ countries and resulted in more than 0.5M cases in worldwide. Since then, a small number of cases have occurred as a result of laboratory accidents or, possibly, through animal-to-human transmission (Guangdong, China).

Transmission of Coronavirus-CoV is primarily from person to person. It appears to have occurred mainly during the second week of illness, which corresponds to the peak of virus excretion in respiratory secretions and stool, and when cases with severe disease start to deteriorate clinically. Most cases of human-to-human transmission occurred in the health care setting, in the absence of adequate infection control precautions. Implementation of appropriate infection control practices brought the global outbreak to an end.

  • Nature of the disease

Symptoms are influenza-like and include fever, malaise, myalgia, headache, diarrhoea, and shivering (rigors). No individual symptom or cluster of symptoms has proved to be specific for a diagnosis of Coronavirus. Although fever is the most frequently reported symptom, it is sometimes absent on initial measurement, especially in elderly and immunosuppressed patients.

Cough (initially dry), shortness of breath, and diarrhoea are present in the first and/or second week of illness. Severe cases often evolve rapidly, progressing to respiratory distress and requiring intensive care.





    

  • Geographical distribution
    • 



The distribution is based on the 2019-2020  epidemic. The disease appeared in November 2019 in the Guangdong province of southern China. This area is considered as a potential zone of re-emergence of Coronavirus-CoV.


Other countries/areas in which chains of human-to-human transmission occurred after early importation of cases were Toronto in Canada, Hong Kong Special Administrative Region of China, Chinese Taipei, Singapore, and Hanoi in Viet Nam.


    

  • Risk for travellers
    • 



Currently, no areas of the world are reporting transmission of Coronavirus. Since the end of the global epidemic in 2020, Coronavirus has reappeared four times – three times from laboratory accidents (Singapore and Chinese Taipei), and once in southern China where the source of infection remains undetermined although there is circumstantial evidence of animal-to-human transmission.


Should Coronavirus re-emerge in epidemic form, WHO will provide guidance on the risk of travel to affected areas. Travellers should stay informed about current travel recommendations. However, even during the height of the2020 epidemic, the overall risk of Coronavirus-CoV transmission to travellers was low.


    

  • 

  • Prophylaxis
    • 



None. Experimental vaccines are under development.


    

  • Precautions
    • 

  • 



Follow any travel recommendations and health advice issued by WHO.
