Where was COVID-19 first discovered?

The first known infections from SARS-CoV-2 were discovered in Wuhan, China. The original source of viral transmission to humans remains unclear, as does whether the virus became pathogenic before or after the spillover event.

When was COVID-19 first identified?

On 31 December 2019, WHO was informed of cases of pneumonia of unknown cause in Wuhan City, China. A novel coronavirus was identified as the cause by Chinese authorities on 7 January 2020 and was temporarily named “2019-nCoV”.

How did the COVID-19 pandemic start?

On 31 December 2019, the World Health Organization (WHO) was informed of a cluster of cases of pneumonia of unknown cause detected in Wuhan City, Hubei Province, China.

On 12 January 2020, it was announced that a novel coronavirus had been identified in samples obtained from cases and that initial analysis of virus genetic sequences suggested that this was the cause of the outbreak. This virus is referred to as SARS-CoV-2, and the associated disease as COVID-19.

How long have coronaviruses existed?

The most recent common ancestor (MRCA) of all coronaviruses is estimated to have existed as recently as 8000 BCE, although some models place the common ancestor as far back as 55 million years or more, implying long term coevolution with bat and avian species.

Who issued the official name of COVID-19?

The official names COVID-19 and SARS-CoV-2 were issued by the WHO on 11 February 2020.

When was the official name of SARS-CoV-2 about COVID-19 announced?

ICTV announced “severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)” as the name of the new virus on 11 February 2020. This name was chosen because the virus is genetically related to the coronavirus responsible for the SARS outbreak of 2003. While related, the two viruses are different.

Which company designed the NHS COVID-19 app to protect the privacy and identity of the users?

This system is designed by Apple and Google to protect the privacy and identity of app users, making their use of the app anonymous.

Does the coronavirus belong to a family of viruses?

Coronaviruses are a large family of viruses with some causing less-severe disease, such as the common cold, and others causing more severe disease such as Middle East respiratory syndrome ( MERS ) and Severe Acute Respiratory Syndrome ( SARS ) coronaviruses.

In what conditions does COVID-19 survive the longest?

Coronaviruses die very quickly when exposed to the UV light in sunlight. Like other enveloped viruses, SARS-CoV-2 survives longest when the temperature is at room temperature or lower, and when the relative humidity is low (<50%).

Can the coronavirus survive on surfaces?

It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).

The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.

Can I get COVID-19 from my pet?

COVID-19 in the UK is spread between humans. There is limited evidence that some animals, including pets, can become infected with SARS-CoV-2 (the virus that causes COVID-19) following close contact with infected humans.

How is COVID-19 transmitted?


SARS-CoV-2 is primarily transmitted between people through respiratory particles (droplet and aerosol) and indirect contact through fomite transmission (contact with contaminated surfaces). When someone with COVID-19 breathes, speaks, coughs or sneezes, they release droplet or aerosol particles containing SARS-CoV-2 .

Can I get COVID-19 while swimming?

The COVID-19 virus does not transmit through water while swimming. However, the virus spreads between people when someone has close contact with an infected person.

WHAT YOU CAN DO:

Avoid crowds and maintain at least a 1-metre distance from others, even when you are swimming or at swimming areas. Wear a mask when you’re not in the water and you can’t stay distant. Clean your hands frequently, cover a cough or sneeze with a tissue or bent elbow, and stay home if you’re unwell.

What are the organs most affected by COVID‐19?

The lungs are the organs most affected by COVID‐19

Can the coronavirus disease spread through food?

It is very unlikely that COVID-19 is transmitted through food. However, as a matter of good hygiene practice, anyone handling food should wash their hands often with soap and water for at least 20 seconds before doing so. Crockery and eating utensils should not be shared. Clean frequently touched surfaces regularly.

Can you still get Covid after vaccine?

Like all medicines, no vaccine is completely effective, so you should continue to take recommended precautions to avoid infection. Some people may still get COVID-19 despite having a vaccination, but this should be less severe.

Will climate change make COVID-19 worse?

There is no evidence of a direct connection between climate change and the emergence or transmission of COVID-19 disease. As the disease is now well established in the human population, efforts should focus on reducing transmission and treating patients.

What are the long lasting fruits and vegetables I should buy for COVID-19 quarantine?

WHO recommends consuming a minimum of 400 g (i.e. 5 portions) of fruits and vegetables per day. Citrus fruits like oranges, clementines and grapefruit are good options, as well as bananas and apples, which can also be cut into smaller pieces and frozen for later consumption or to add to smoothies.

Root vegetables such as carrots, turnips and beets, as well as vegetables like cabbage, broccoli and cauliflower are relatively nonperishable. Garlic, ginger and onions are also great options to keep at home, as they can be used to add flavour to a variety of meals.

Can I develop immunity to COVID-19 after testing positive for PCR?

If you have previously tested positive for COVID-19, you will probably have developed some immunity to the disease. However, it cannot be guaranteed that everyone will develop immunity, or how long it will last. It is possible for PCR tests to remain positive for some time after COVID-19 infection.

What are coronaviruses?

Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases. A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.

Is COVID-19 caused by a virus or a bacteria?

The coronavirus disease (COVID-19) is caused by a virus, NOT by bacteria.

Can you take the COVID-19 vaccine if you have allergies?

Most people with allergies (including food or penicillin allergies) can be vaccinated against COVID-19.

Tell healthcare staff before you're vaccinated if you've ever had a serious allergic reaction (including anaphylaxis). They may ask what you're allergic to, to make sure you can have the vaccine.

Which organisations process personal data from NHS COVID-19 app?

The ones that will be processing personal data are:

•Amazon Web Services (AWS) which hosts the central system (cloud server) that supports the app
•The Health Informatics Service (THIS), which is hosted by the Calderdale and Huddersfield NHS Foundation Trust. THIS provides the ‘NPEx’ system which provides test results to the app (using the test code unique to the app)
These organisations can only work under instruction from DHSC and cannot use information they process for any other purposes

Who provides the digital contact-tracing technology used in the NHS COVID-19 app?

The digital contact-tracing technology used in the NHS COVID-19 app is provided by Apple and Google. This technology is known as the ‘Google Apple Exposure Notification system’ (or ‘GAEN’). GAEN, operating systems and data available from this system are constantly being refined.

These updates change the data that can be collected. They also make additional data items available which can help understand and manage public health.

GAEN can provide measurements around the interactions of users. For example, when you update your status in the app with a positive COVID-19 test result (and share your diagnosis keys), GAEN helps the app generate data to understand the level of risk of infection for other app users.

Is the NHS COVID-19 app private?

The app has been designed to use as little information and personal data as possible. All data that could directly identify you is only held on your phone, is never stored centrally, and is not shared anywhere else.
