Wuhan, the 7th-largest city in China, is the epicentre of a virus outbreak, the first few cases of which were reported in December 2019. This is an ongoing development and is also important for the UPSC exam, from the perspective of health and epidemic control. In this article, you can read all the latest on the COVID-19 (Wuhan Coronavirus) outbreak.

COVID-19 Latest Information
In April 2021, it has been seen that many coronavirus patients are being infected with mucormycosis (also called black fungus), especially in Maharashtra. Know more about mucormycosis in the linked article.
COVID-19 New Virus Strain
A new strain of the coronavirus emerged in the United Kingdom and has spread to other countries including India.
- According to some sources, this variant could be about 70% more transmissible than the original strain.
- India reported positive cases of the new strain around the end of December 2020.
- More than fifty countries, including India, have imposed travel restrictions to and from the UK.
- The new strain is called SARS-CoV-2 VUI 202012/01 or “B.1.1.7.”
- It was first discovered in September in the southeast of England.
- This strain emerged independently and is not related to another new strain that emerged in South Africa in mid-December.
- The new strain includes a genetic mutation in the “spike” protein that the SARS-CoV-2 coronavirus uses to infect human cells.
- There are concerns that although there may not be much change in the symptoms and the mortality rates remain the same, if the virus spreads more efficiently it may lead to increased hospitalisations, that strain the health systems.
- But experts say that there is a high probability that the vaccines being prepared for the virus would work for the new strain as well.
- As on 11 January 2021, there were 96 cases of the new UK mutant strain in India.
According to the WHO, there are over 50 vaccine candidates for COVID-19 in various stages of clinical trials.
Currently, the following vaccines are under trial in India for the fight against COVID-19:

Wuhan Coronavirus – Introduction
- This is a new coronavirus that has been identified for the first time in the city of Wuhan, the capital of the Hubei Province in mainland China.
- It was identified after people developed pneumonia without an evident cause and where current vaccines and treatment methods were not effective.
- There have been around 80000 people infected with the virus in China. There have also been about 4600 fatalities there, exceeding those from SARS.
- Cases have also been reported outside China, in Hong Kong, South Korea, Iran, Italy, Australia, Thailand, France, Spain, Germany, the US, countries in West Asia, etc. totaling over 200 countries. India reported its first case towards the end of January 2020.
- Worldwide, there have been more than 2.18 crore cases and more than 7.72 lakh deaths.
- Some of the worst-effected countries are Brazil, the US, the UK, Spain, India and Italy.
- There is not much known about the new coronavirus, which has been designated 2019-nCoV.
- It is considered a novel virus outbreak because the virus is novel (new – not seen earlier).
- Symptoms of the new virus include:
- Muscle pain
- Breathing difficulties
- Can cause pneumonia (infection of one or both lungs)
- Can be fatal
- After a slow onset in an infected body, the disease spreads rapidly in the second week.
- Hypoxemia caused due to intensifying lung injury leads to difficulty in breathing and the need for oxygen therapy.
- Another common complication observed is ARDS (acute respiratory distress syndrome).
- Other complications include acute kidney injury, septic shock and virus-induced cardiac injury.
- The incubation period for the virus ranges from 2 to 14 days.
- The incubation period is the time starting from exposure to the virus to developing symptoms.
- During the incubation period, the Wuhan virus is contagious.
- The virus is believed to have originated in a seafood market in Wuhan that was involved in the illegal sale of wildlife.
- Many early patients of the virus had some link to the market, suggesting an animal-to-human spread.
- A further rise in the number of patients (who have not had exposure to the market) suggests that person-to-person spread is happening. However, at present, it is not clear as to how this spreading occurs between people.

What is Coronavirus?
Coronaviruses are a large family of viruses that are common in various species of animals, such as cattle, camels, bats, and cats. They cause diseases ranging from cold to SARS.
- In some cases, animal coronaviruses can infect humans, which can then spread from person to person.
- This happened in the case of the SARS and MERS coronaviruses. It is also suggested that this might be happening in the current China virus case.
- Coronaviruses cause respiratory infections in humans which are generally mild, but sometimes, can be fatal.
- Coronaviruses are physically large as far as viruses go (26 – 32 kilobases), having a surface of spike projections (which resembles a crown and hence the name ‘corona’).
- Like the influenza virus, the coronavirus spreads through both direct and indirect contact.
- Direct contact happens through a physical transfer of the microorganism through close contact with oral secretions.
- Indirect contact happens when a person infected with the virus sneezes or coughs, which spreads the virus droplets on surfaces.
- Person-to-person spread occurred with MERS and SARS mainly via respiratory droplets produced when an infected person coughs or sneezes, quite like how influenza and other respiratory pathogens spread.
There are seven strains of human coronaviruses. They are:
- Human coronavirus 229E (HCoV-229E)
- Human coronavirus OC43 (HCoV-OC43)
- Human coronavirus NL63 (HCoV-NL63, New Haven coronavirus)
- Human coronavirus HKU1
- Middle East respiratory syndrome coronavirus (MERS-CoV)
- Novel coronavirus (2019-nCoV) – Wuhan pneumonia or Wuhan coronavirus, COVID-19
Coronaviruses are known to cause a significant percentage of all common colds in human beings (adults and children).
Given below is a comparison of three coronaviruses that hit the headlines:
|Full form||Novel coronavirus||Severe acute respiratory syndrome||Middle East respiratory syndrome|
|Country of origin||China||China||Saudi Arabia|
|Primary host||Probably bats (unconfirmed)||Bats||Bats|
|Intermediate host||Not identified||Masked Palm Civets||Camels|
For more information on the latest available scientific data on the COVID-19 virus, refer to our PIB dated 1st April, 2020.
Diseases that pass from animals to humans are called zoonotic diseases. They are rare. The chief concern with them is that since they are new to humans, the human body does not have any immunity to them.
Zoonotic diseases are also called zoonoses. They are caused by harmful germs such as bacteria, viruses, fungi and parasites.
How Zoonotic Diseases spread?
- Direct contact: with saliva, urine, and other bodily fluids, by touching or petting animals.
- Indirect contact: coming into contact with areas where animals live, or with objects and surfaces that have been contaminated with germs.
- Vector-borne: being bitten by insects like mosquitoes, fleas or ticks.
- Foodborne: eating contaminated food.
More on Zoonotic Diseases.
Measures are taken to combat the Wuhan Coronavirus
There are no specific treatments for human coronaviruses. 2019-nCoV does not have a vaccine or any effective treatment. One method of fighting the spread of the disease is to take preventive measures.
The following is the advisory issued by the Government of India:
- The WHO recommends people to do regular handwashing, cover mouth and nose while coughing or sneezing, and avoid close contact with anyone suspected of being infected or showing respiratory illness symptoms.
- In China, authorities are taking measures to curb the spread of the virus and prevent a SARS-like situation. SARS, which originated in China, spread to more than 35 countries and killed almost 800 people.
- People in public places are asked to wear face masks.
- Schools and universities have extended their winter breaks in view of the epidemic-like situation in Wuhan.
- Hong Kong and Macau have declared emergencies.
- All passengers travelling from China are being checked at airports.
- Travel within China is also highly restricted with private vehicles being banned in Wuhan.
