COVID-19, Coronavirus disease 2019, has been declared a pandemic by the World Health Organization on March 11, 2020. The virus ‘SARS-CoV-2’ is the reason for the outbreak of respiratory disease, which was first reported from Wuhan, China, and has reportedly spread to different countries crossing continents. Before declaring it as a pandemic, WHO placed it as PHEIC (Public Health Emergency of International Concern) on January 30, 2020, and after that, things shifted raising the alarm.

The epicenter of the Coronavirus outbreak is Wuhan, Hubei Province, China. Incidentally, Wuhan is one of the largest live animal and seafood markets. Ironically it is also one of the important biological weapon experimental centers in China. The possibility of spreading the virus from animal to person remains very strong, because of the large-scale live animal trade happens in Wuhan. It is interesting to note that soon after the disease started spreading other parts of China, including those areas where no animal or seafood market, it suggests the possibility of virus spread from person to person.

COVID-19 (Coronavirus disease 2019) is part of an extended virus family which has the potential to spread from animal to person and then spread rapidly from person to person. There are different forms of the virus of this family, which are present in cattle, bats, camels, cats, snakes, and many other animals. They are less prone to jump from animal to person; however, viruses such as SARS-CoV and MERS-CoV have the notorious ability to jump to people and the new variation SARS-CoV-2, which later christened as COVID-19, which stares like a demon on the human race.
The presence of SARS-CoV-2 is prominent on bats. SARS-CoV-2 is very similar to SARC-CoV and MERS-CoV and is a betacoronavirus. The clinical history of patients is very much matching with the symptoms of betacoronavirus. Hence, the possibility of the virus outbreak is from a live animal trade center or human likely to have close interaction. That is the reason, theoretically, it can confirm beyond doubt that the live animal market in Wuhan could be the outbreak point of the disease.
Not all fevers are the symptoms for COVID-19. So, no need to get panic if you don’t have breathing issues, fever, and dry cough. The main symptom of coronavirus are as follows:
- Fever with dry cough and breathing difficulties.
If you feel a combination of all these symptoms, then it could be a warning signal, and you must seek medical help. Check also the following condition; if you have the following warning symptoms, then it is possibly an indication of COVID-19.
- Feeling of pressure in the chest or continuous pain.
- Breathing issues or shortness of breath.
- Bluish lips or face.
- Inability to arouse or confusion.
Coronavirus can transmit from animals to the human being, hence are known as zoonotic. The virus is part of a large family, and there are many viruses common in animals without infecting human breed. These viruses are a reason for the common cold to chronic diseases such as SARS-CoV (Severe Acute Respiratory Syndrome) and MERS-CoV (Middle East Respiratory Syndrome). SARS-CoV is ubiquitous in civet cats, and MERS-CoV is common in camels and from where humans get infected.
General symptoms of diseases are respiratory issues, cough, fever, etc. When it affects severely, it may lead to kidney failure, chronic respiratory disorders such as breathing problems, and also a reason for causing pneumonia. Once the COVID-19 infected, it spread rapidly even though it cannot survive more than 25-30 minutes outside the human body. (WHO)
Incubation period: (Worldometer)
Within 2 days or a maximum of 14 days, the virus has the potential to become/remain contagious. However, the patient does not necessarily show any symptoms of infection.
- WHO estimates the incubation period for COVID-19 is 2 to 10 days.
- National Health Commission of China (NHC) estimates the incubation period between 10 and 14 days.
- As per CDC USA, the incubation period must be 2 to 14 days.
Age, sex and demographics factor of COVID-19: (Worldometer)The statistics of COVID-19 shows, the majority of elderly citizens were the victims of the infectious disease. As per NHC, China, the following information exposes the vulnerability of senior citizens and people who had some medical issues.
- 80% of people who died due to coronavirus infection were above 60 years of age.
- 75% of people had health issues.
- As per WHO, the median age of infection was 45 years, and the virus exposed between 2 to 74 years.
- 71% of the infected people were Males
