A new ‘game-changing’ and 100 percent accurate coronavirus antibody test that can tell whether someone has had the bug has been approved for public use in the UK, public health bosses declared overnight.
The announcement tailed a groundbreaking independent evaluation of a blood blood test developed by a Swiss pharmaceutical company — Public Health England (PHE) announced Roche’s serology test was “highly specific” and had a 100 percent accuracy level.
The Government is in talks with Roche, the Swiss pharmaceutical giant behind the test, to buy millions of the kits that could end the lockdown early.
The examination found that Roche’s serology test was “highly specific” and had an accuracy of 100%.
The test — designed to help determine if a patient has had COVID-19 and whether they have developed antibodies against it — could make historic progress in combatting coronavirus.
The detection of these antibodies could help to indicate if a person has gained immunity against the virus.
Professor John Newton, national co-ordinator of the UK Coronavirus Testing Programme, told foreign reporters: “This is a very positive development because such a highly specific antibody test is a very reliable marker of past infection.
“This in turn may indicate some immunity to future infection although the extent to which the presence of antibodies indicates immunity remains unclear.”
A spokeswoman for the Department of Health and Social Care (DHSC) said: “Antibody testing is an important part of our strategy to counter the spread of COVID-19 and to help us understand who has had the disease.
“In addition to the recent huge expansion of the UK’s swab-based coronavirus testing capacity, we are exploring the use of antibody testing across the NHS and ultimately the wider public.
“We are delighted that devices are progressing through validation, and are actively working on our plans for rolling out antibody testing and will make announcements in due course.”
In March, Boris Johnson said: “The great thing about having a test to see whether you’ve had it enough, is suddenly a green light goes on above your head and you can go back to work safe and confident in the knowledge that you are most unlikely to get it again.
“So for an economic point of view, from a social point of view, it really could be a game-changer.”
Severin Schwan, chief executive of Roche Group, said: “Thanks to the enormous efforts of our dedicated colleagues we are now able to deliver a high-quality antibody test in high quantities, so we can support healthcare systems around the world with an important tool to better manage the COVID-19 health crisis.
Health Secretary Matt Hancock last week said the UK was in talks with Roche about a “very large-scale roll-out” of coronavirus antibody testing.
But he acknowledged that there had been problems with antibody testing, having previously said the UK would order 17.5 million home testing kits only to find they did not work.
“There has been false hope before in antibody testing and so we’ll make announcements when we’re absolutely ready,” he said.
Earlier this month, Roche’s antibody test won emergency approval from the US Food and Drug Administration.
What is an antibody test and why is it important?
When a person gets infected with a virus, the body starts making specially designed proteins called antibodies to fight the infection.
After they recover, those antibodies float in the blood for months, maybe even years.
Therefore, an accurate antibody test can identify if someone has had COVID-19 and recovered, even if they showed no symptoms of the virus.
Current testing only identifies those who have it now.
If introduced, scientists will hope to obtain valuable data on the spread of the pandemic which will help with planning for future outbreaks as well as potential vaccines and treatments.
It will also give more accurate numbers on exactly how many people were infected to see how prevalent the virus is.
There have been suggestions those who have had the virus and have recovered will have immunity, however scientists say it is too early to be sure.
Previous tests have not been as accurate meaning they detect antibodies against other coronaviruses such as the common cold – producing what is known as a false positive.
COVID9 is caused by a new coronavirus. Coronaviruses are a large family of viruses that are common in people and many different species of animals, including camels, cattle, cats, and bats. Rarely, animal coronaviruses can infect people and then spread between people such as with MERS-CoV, SARS-CoV, and now with this new virus, named SARS-CoV-2.
The SARS-CoV-2 virus is a betacoronavirus, like MERS-CoV and SARS-CoV. All three of these viruses have their origins in bats. The sequences from U.S. patients are similar to the one that China initially posted, suggesting a likely single, recent emergence of this virus from an animal reservoir.
Early on, many of the patients at the epicenter of the outbreak in Wuhan, Hubei Province, China had some link to a large seafood and live animal market, suggesting animal-to-person spread. Later, a growing number of patients reportedly did not have exposure to animal markets, indicating person-to-person spread. Person-to-person spread was subsequently reported outside Hubei and in countries outside China, including in the United States. Most international destinations now have ongoing community spread with the virus that causes COVID-19, as does the United States. Community spread means some people have been infected and it is not known how or where they became exposed. Learn more about the spread of this coronavirus that is causing COVID-19.

About COVID-19 via Center for Disease Control and Prevention
The COVID-19 pandemic is a serious global health threat and CDC is committed to stopping the global spread. CDC has a long history of improving public health capacity throughout the world to contain outbreaks at their source and minimize their impact.
CDC’s technical support to ministries of health and other local and international partners is delivered in coordination with the U.S. Department of State, the U.S. Agency for International Development, other U.S. government agencies, and other stakeholders including multilateral organizations.
CDC works globally to limit human-to-human transmission of COVID-19, minimize the impact of COVID-19 in vulnerable countries with limited preparedness capacity, and reduce threats that pose current and future risk to the United States. Globally, CDC works to:
- Strengthen capacity to prevent, detect, investigate and respond to local COVID-19
- Mitigate COVID-19 transmission in the community, across borders, and in healthcare facilities
- Support governments, nongovernmental organizations, and healthcare facilities to rapidly identify, triage, and diagnose potential cases to improve patient care and minimize disruptions to essential health services
- Address crucial unknowns regarding clinical severity, extent of transmission and infection with support for special investigations and other forms of cooperation between CDC and country partners
- Ensure readiness to implement vaccines and therapeutics when available
Since 2015, CDC has been a key implementing partner of the USG Global Health Security Agenda (GHSA). GHSA investments have helped countries build national capacities to prevent, detect, and respond to infectious disease threats. These investments and partnerships have laid foundations to rapidly and effectively prepare for emerging threats, including the current COVID-19 pandemic. Lessons learned from addressing HIV, influenza, Ebola, dengue, Zika, and many other viruses are being applied to the COVID-19 response.
Outbreaks can be stressful
The outbreak of coronavirus disease 2019 (COVID-19) may be stressful for people. Fear and anxiety about a disease can be overwhelming and cause strong emotions in adults and children. Coping with stress will make you, the people you care about, and your community stronger.
Stress during an infectious disease outbreak can include
- Fear and worry about your own health and the health of your loved ones
- Changes in sleep or eating patterns
- Difficulty sleeping or concentrating
- Worsening of chronic health problems
- Worsening of mental health conditions
- alcohol, tobacco, or other drugs
Everyone reacts differently to stressful situations
How you respond to the outbreak can depend on your background, the things that make you different from other people, and the community you live in.
People who may respond more strongly to the stress of a crisis include
- Older people and people with chronic diseases who are at higher risk for severe illness from COVID-19
- Children and teens
- People who are helping with the response to COVID-19, like doctors, other health care providers, and first responders
- People who have mental health conditions including problems with substance use
Take care of yourself and your community
Taking care of yourself, your friends, and your family can help you cope with stress. Helping others cope with their stress can also make your community stronger.
Ways to cope with stress
- Take breaks from watching, reading, or listening to news stories, including social media. Hearing about the pandemic repeatedly can be upsetting.
- Take care of your body.
- Take deep breaths, stretch, or meditate.
- Try to eat healthy, well-balanced meals.
- Exercise regularly, get plenty of sleep.
- Avoid alcohol and drugs.
- Make time to unwind. Try to do some other activities you enjoy.
- Connect with others. Talk with people you trust about your concerns and how you are feeling.
Know the facts to help reduce stress
Sharing the facts about COVID-19. Understanding the risk to yourself and people you care about can make an outbreak less stressful.
When you share accurate information about COVID-19, you can help make people feel less stressed and make a connection with them.
Take care of your mental health
Call your healthcare provider if stress gets in the way of your daily activities for several days in a row.
People with preexisting mental health conditions should continue with their treatment and be aware of new or worsening symptoms. Additional information can be found at the Substance Abuse and Mental Health Services Administration (SAMHSA) Disaster Preparednessexternal icon page.
Risk of animals spreading COVID-19 to people
Some coronaviruses that infect animals can sometimes be spread to humans and then spread between people, but this is rare. This is what happened with the virus that caused the current outbreak of COVID-19. However, we do not know the exact source of this virus. Public health officials and partners are working hard to identify the source of COVID-19. The first infections were linked to a live animal market, but the virus is now spreading from person to person.
The virus that causes COVID-19 spreads mainly from person to person through respiratory droplets from coughing, sneezing, and talking. Recent studies show that people who are infected but do not have symptoms likely also play a role in the spread of COVID-19. At this time, there is no evidence that animals play a significant role in spreading the virus that causes COVID-19. Based on the limited information available to date, the risk of animals spreading COVID-19 to people is considered to be low.
Risk of people spreading COVID-19 to animals
We are still learning about this virus, but we know it is primarily spreading from person-to-person and it appears that it can spread from people to animals in some situations.
The first case in the United States of an animal testing positive for the virus that causes COVID-19 was a tiger with a respiratory illness at a zoo in New York City. Samples from this tiger were collected and tested after several lions and tigers at the zoo showed signs of respiratory illness. Public health officials believe these large cats became sick after being exposed to a zoo employee who was infected with the virus that causes COVID-19. This investigation is ongoing.
CDC is working with human and animal health partners to monitor this situation and will continue to provide updates as information becomes available. Further studies are needed to understand if and how different animals could be affected by COVID-19.
Running Essential Errands
As communities across the United States take steps to slow the spread of COVID-19 by limiting close contact, people are facing new challenges and questions about how to meet basic household needs, such as buying groceries and medicine, and completing banking activities. The following information provides advice about how to meet these household needs in a safe and healthy manner.
Find additional information for people who are at higher risk for severe illness from COVID-19.
Shopping for food and other household essentials
- Avoid shopping if you are sick or have symptoms of COVID-19, which include a fever, cough, or shortness of breath.
- Order online or use curbside pickup.
- Order food and other items online for home delivery or curbside pickup (if possible).
- Only visit the grocery store, or other stores selling household essentials, in person when you absolutely need to. This will limit your potential exposure to others and the virus that causes COVID-19.
Protect yourself while shopping
- Stay at least 6 feet away from others while shopping and in lines.
- Cover your mouth and nose with a cloth face covering when you have to go out in public.
- When you do have to visit in person, go during hours when fewer people will be there (for example, early morning or late night).
- If you are at higher risk for severe illness, find out if the store has special hours for people at higher risk. If they do, try to shop during those hours. People at higher risk for severe illness include adults 65 or older and people of any age who have serious underlying medical conditions.
- Disinfect the shopping cart, use disinfecting wipes if available.
- Do not touch your eyes, nose, or mouth.
- If possible, use touchless payment (pay without touching money, a card, or a keypad). If you must handle money, a card, or use a keypad, use hand sanitizer right after paying.
- After leaving the store, use hand sanitizer.
- When you get home, wash your hands with soap and water for at least 20 seconds.
- Follow food safety guidelines: clean, separate, cook, chill. There is no evidence that food or food packaging has been linked to getting sick from COVID-19.
Accepting deliveries and takeout orders
- Pay online or on the phone when you order (if possible).
- Accept deliveries without in-person contact whenever possible. Ask for deliveries to be left in a safe spot outside your house (such as your front porch or lobby), with no person-to-person interaction. Otherwise, stay at least 6 feet away from the delivery person.
Wash your hands or use hand sanitizer after accepting deliveries or collecting mail
- After receiving your delivery or bringing home your takeout food, wash your hands with soap and water for 20 seconds. If soap and water are not available, use a hand sanitizer with at least 60% alcohol.
- After collecting mail from a post office or home mailbox, wash your hands with soap and water for at least 20 seconds or use a hand sanitizer with at least 60% alcohol.
- If you must visit the bank, use the drive-through ATM if one is available. Clean the ATM keyboard with a disinfecting wipe before you use it.
- When you are done, use a hand sanitizer with at least 60% alcohol. Wash your hands with soap and water for at least 20 seconds when you get home.
- Use disinfecting wipes on handles and buttons before you touch them (if available).
- After fueling, use a hand sanitizer with at least 60% alcohol. Wash your hands for at least 20 seconds when you get home or somewhere with soap and water.
Going to the doctor or getting medicine
- Use telemedicine, if available, or communicate with your doctor or nurse by phone or e-mail.
- Talk to your doctor about rescheduling procedures that are not urgently needed.
If you must visit in-person, protect yourself and others
- If you think you have COVID-19, let the office know and follow guidance.
- Cover your mouth and nose with a cloth face covering when you have to go out in public.
- Do not touch your eyes, nose, or mouth.
- Use disinfecting wipes on frequently touched surfaces such as handles, knobs, touchpads (if available).
- Stay at least 6 feet away from others while inside and in lines.
- When paying, use touchless payment methods if possible. If you cannot use touchless payment, sanitize your hands after paying with card, cash, or check. Wash your hands with soap and water for at least 20 seconds when you get home.
Limit in-person visits to the pharmacy
- Plan to order and pick up all your prescriptions at the same time.
- If possible, call prescription orders in ahead of time. Use drive-thru windows, curbside services (wait in your car until the prescription is ready), mail-order, or other delivery services. Do the same for pet medicine.
- Check with your doctor and pharmacist to see if you can get a larger supply of your medicines so you do not have to visit the pharmacy as often.
- If you or a member of your household has signs of COVID-19, call your doctor first, instead of going to the office or the emergency department.
Staying physically active is one of the best ways to keep your mind and body healthy. In many areas, people can visit parks, trails, and open spaces as a way to relieve stress, get some fresh air and vitamin D, stay active, and safely connect with others.
Visit parks that are close to your home
- Traveling long distances to visit a park may contribute to the spread of COVID-19 as:
- Most travel requires you to stop along the way or be in close contact with others.
- Travel may also expose you to surfaces contaminated with the virus that causes COVID-19.
Prepare before you visit
State or Local Parks: State and local authorities will decide whether parks and other recreational facilities will open. Check with the park in advance to be sure you know which areas or services are open, such as bathroom facilities and concessions, and bring what you need with you.
National Parks: The National Park Service will decide on a park-by-park basis whether a national park will be open. Please check with individual parks for specific details since, in many cases, visitor centers, concessions, and bathroom facilities might be closed.
Beaches or Other Swimming Areas: State and local authorities will decide whether natural bodies of water and beaches or swim areas will be open. Please check with individual beaches or swim areas for specific details.
Stay 6 feet away from others and take other steps to prevent COVID-19
If a park, beach, or recreational facility is open for public use, visiting is okay as long as you practice social distancing and everyday steps such as washing hands often and covering coughs and sneezes. Follow these actions when visiting a park, beach, or recreational facility:
- Stay at least six feet from others at all times. This might make some open areas, trails, and paths better to use. Do not go into a crowded area.
- Avoid gathering with others outside of your household.
- Wash hands often with soap and water for at least 20 seconds, especially after going to the bathroom, before eating, and after blowing your nose, coughing, or sneezing.
- Bring hand sanitizer with at least 60% alcohol to use if soap and water are not available.
Play it safe around and in swimming pools, and keep space between yourself and others
There is no evidence that COVID-19 can be spread to humans through the water. Proper operation, maintenance, and disinfection (with chlorine or bromine) of pools should kill COVID-19.
Swimming and other water-related activities are excellent ways to get the physical activity needed for a healthy life. If you are not sick or experiencing symptoms of COVID-19, it is safe to use swimming pools as long as steps are taken to reduce the spread of COVID-19:
- Practice social distancing by staying at least six feet (two meters) from others.
- Avoid large gatherings of more than 10 people.
- Keep your hands clean by washing hands with soap and water, especially after going to the bathroom, before eating, and after blowing your nose, coughing, or sneezing. Use an alcohol-based hand sanitizer that contains at least 60% alcohol if soap and water are not available.
Testing for COVID-19
- A viral test tells you if you have a current infection.
- An antibody test tells you if you had a previous infection
An antibody test may not be able to show if you have a current infection, because it can take 1-3 weeks after infection to make antibodies. We do not know yet if having antibodies to the virus can protect someone from getting infected with the virus again, or how long that protection might last.
Who should be tested
To learn if you have a current infection, viral tests are used. But not everyone needs this test.
- Most people will have mild illness and can recover at home without medical care and may not need to be tested.
- CDC has guidance for who should be tested, but decisions about testing are made by state and local health departments or healthcare providers.
- If you have symptoms of COVID-19 and want to get tested, call your healthcare provider first.
- You can also visit your state or local health department’s website to look for the latest local information on testing.
- Although supplies of tests are increasing, it may still be difficult to find a place to get tested.
- If you test positive for COVID-19 by a viral test, know what protective steps to take if you are sick or caring for someone.
- If you test negative for COVID-19 by a viral test, you probably were not infected at the time your sample was collected. However, that does not mean you will not get sick. The test result only means that you did not have COVID-19 at the time of testing.
If you test positive or negative for COVID-19, no matter the type of test, you still should take preventive measures to protect yourself and others.
If you or a member of your household has signs of COVID-19, call your doctor first, instead of going to the office or the emergency department.
Call 911 if you believe it is an emergency. See also: What to do if you are sick.
