COVID-19 is a highly infectious respiratory disease caused by a new corona virus. The disease was discovered in China in December 2019 and has since spread around the world, causing an unprecedented public health crisis. For health, safety, and medical emergencies or updates on the novel corona virus pandemic, please visit the CDC (Centers for Disease Control and Prevention) and WHO(World Health Organization). A coronavirus is a type of virus. As a group, coronaviruses are common across the world. Generally, coronavirus can cause more severe symptoms in people with weakened immune systems, older people, and those with long term conditions like diabetes, cancer and chronic lung disease.

What are the signs and symptoms of this new virus?

The most common symptoms of this new coronavirus (COVID-19) are a new continuous cough and/or high temperature. Some people may also experience shortness of breath.

Common symptoms:

Some people may experience:

some people are symptoms in few days.
On average it takes 5–6 days from when someone is infected with the virus for symptoms

full list of symptoms is still being investigated by the Centers for Disease Control and Prevention (CDC)Trusted Source.

How does this new coronavirus spread?

The main route of transmission is from cough and sneeze droplets. These droplets fall on people in the vicinity and can be directly inhaled or picked up on the hands and transferred when someone touches their face.

How long any respiratory virus survives will depend on a number of factors; for example:

How many cases do we have in the UK?

As of 9am 5 May, there have been 1,383,842 tests, with 84,806 tests on 4 May. 1,015,138 people have been tested of which 194,990 tested positive. As of 5pm on 4 May, of those tested positive for coronavirus, across all settings, 29,427 have sadly died
We will update these figures daily.

Will everyone who has symptoms get tested?

As we have now moved into the delay phase of the outbreak, we will start to change who gets tested. We now understand that the virus is widely circulating in the community which means that we should assume that anyone with symptoms has coronavirus. We are working to increase the number of tests to 25,000 a day. This increased capacity is expected to be ready by the end of April. Older and vulnerable groups will be prioritized, to ensure that they access the right treatment and care quickly. People who are generally well will not be tested and should manage their condition at home.

How do we know if the virus is evolving?

PHE has used whole genome sequencing to sequence the viral genome from the first two positive cases in this country and has made the sequence available to the scientific community. Our findings are consistent with viral genomes sequenced in China.

How are coronaviruses diagnosed?

COVID-19 can be diagnosed similarly to other conditions caused by viral infections: using a blood, saliva, or tissue sample. However, most tests use a cotton swab to retrieve a sample from the inside of your nostrils. Tests are conducted by the CDC, some state health departments, and some commercial companies. See your state’s health department websiteTrusted Source to find out where testing is offered near you. On April 21, the Food and Drug Administration (FDA)Trusted Source approved the use of the first COVID-19 home testing kit. Using the cotton swab provided, people will be able to collect a nasal sample and mail it to a designated laboratory for testing. The emergency use authorization specifies that the test kit is authorized for use by people who healthcare

What treatments are available? There’s currently no treatment specifically approved for COVID-19, and no cure for an infection, although treatments and vaccines are currently under study. Instead, treatment focuses on managing symptoms as the virus runs its course. Seek medical help if you think you have COVID-19. Your doctor will recommend treatment for any symptoms or complications that develop, and let you know if you need to seek emergency treatment. Other coronaviruses like SARS and MERS are also treated by managing symptoms. In some cases, experimental treatments are tested to see how effective they are. Examples of therapies used for these illnesses include:

What are the possible complications from COVID-19?

The most serious complication of COVID-19 is a type of pneumonia that’s been called 2019 novel corona-virus-infected pneumonia (NCIP). Results from a 2020 studyTrusted Source of 138 people admitted into hospitals in Wuhan, China with NCIP, found that 26 percent of those admitted had severe cases and needed to be treated in the intensive care unit (ICU). About 4.3 percent of these people who were admitted to the ICU died from this type of pneumonia. It should be noted that people who were admitted to the ICU were on average older and had more underlying health conditions than people who didn’t go to the ICU

How can you prevent coronaviruses?

The best way to prevent the spread of infection is to avoid or limit contact with people who are showing symptoms of COVID-19 or any respiratory infection. The next best thing you can do is practice good hygiene and physical distancing to prevent bacteria and viruses from spreading.

Should you wear a mask?

Face masks play a very important role in clinical settings, such as hospitals but there’s very little evidence of widespread benefit from their use outside of these clinical settings. Face masks must be worn correctly, changed frequently, removed properly and disposed of safely in order to be effective. If you’re out in a public setting where it’s difficult to follow physical distancing guidelines Trusted SourCDC recommends that you wear a cloth face mask that covers your mouth and noseThat’s because they can block the respiratory droplets of people who may be asymptomatic or people who have the virus but have gone undiagnosed. Respiratory droplets get into the air when you exhale, talk, cough, or sneeze.You can make your own mask using basic materials such as a bandana, a T-shirt, or cotton fabric. The CDC provides instructions Trusted Source. Cloth masks are preferred for the general public, since other types of masks should be reserved for healthcare workers. It’s critical to keep the mask clean. Wash it each time you use it. Avoid touching the front of it with your hands. Also, try to avoid touching your mouth, nose, and eyes when you remove it. This prevents you from possibly transferring the virus from a mask to your hands and from your hands to your face. Keep in mind that wearing a mask isn’t a replacement for other preventive measures, such as frequent hand washing and practicing physical distancing. All of them are important. Certain people shouldn’t wear face masks. They include children under 2 years old, people who have trouble breathing, and people who are unable to remove their own masks.

Is hand sanitizer effective?

The best way to protect yourself from infections like coronavirus is to regularly wash your hands with soap and water. If soap or water aren’t available and your hands are visibly clean, then sanitiser gel can be used. But proper hand washing is the most effective method and this should be your first choice.

What are the other types of coronaviruses?

The word corona means “crown,” and when examined closely, the round virus has a “crown” of proteins called peplomers jutting out from its center in every direction. These proteins help the virus identify whether it can infect its host. severe acute respiratory syndrome (SARS) was also linked to a highly infectious coronavirus back in the early 2000s. The SARS virus has since been contained.


This isn’t the first time a corona virus has made news — the 2003 SARS outbreak was also caused by a corona virus. As with the 2019 virus, the SARS virus was first found in animals before it spread to humans. The SARS virus is thought toTrusted Source have come from bats and then transferred to another animal, and then to humans. Once transmitted to humans, the SARS virus began spreading quickly among people. What makes the new corona virus so newsworthy is that a treatment or cure hasn’t yet been developed to help prevent its rapid spread from person to person. SARS has been successfully contained.

What’s the outlook?

First and foremost, don’t panic. You don’t need to be quarantined unless you suspect you have contracted the virus or have a confirmed test result. Following simple hand washing and physical distancing guidelines are the best ways to help protect you from being exposed to the virus. The 2019 corona virus probably seems scary when you read the news about new deaths, quarantines
