Is This Virus Comparable With Sars Or With The Seasonal Flu
The novel coronavirus detected in China in 2019, SARS-CoV-2, is closely related to the original SARS-CoV. Both viruses cause respiratory illnesses known as COVID-19 and SARS, respectively. Influenza, also known as the flu, is a respiratory illness with similar symptoms but caused by a different group of viruses, the influenza viruses.
SARS, the respiratory illness caused by the original SARS-CoV, emerged in late 2002 in China and caused more than 8 000 cases in 33 countries over the course of eight months. Around one in 10 people who developed SARS died.
COVID-19, caused by SARS-CoV-2, emerged in late 2019 and spread very quickly across the globe. As SARS-CoV-2 is a new virus, most people did not have immunity for it, so the entire human population was potentially susceptible to SARS-CoV-2 infection at the start of the pandemic.
Within the first 20 months of the COVID-19 pandemic, 208 million cases were reported worldwide, 36 million alone in the EU/EEA. Due to the nature of the disease, where some infected individuals may not have symptoms and even those who do may not all be tested, it is assumed that there are many undiagnosed cases. The likelihood of death depends on age and is highest among older people.
Vaccines against COVID-19 have only recently become available while influenza vaccines were developed as early as the 1930s. No vaccine is available for SARS.

If You Take Part In Asymptomatic Testing
People in England who do not have symptoms of COVID-19 can take part in regular testing using LFD tests. Asymptomatic testing can help to identify people who may have COVID-19, but are not feeling unwell, so that they can take steps to reduce the spread of infection to others.
Asymptomatic LFD testing is most effective when tests are taken regularly, twice a week. More information on ordering LFD tests is available. If you test positive for COVID-19 by LFD test, you should self-isolate and follow this guidance. You should also request a follow-up PCR test.
LFD tests can be taken in 2 ways:
an assisted test is where the person takes the test themselves under the supervision of a trained operator, and this operator processes the test, reads and reports the result
a home test is where a person takes the test themselves and reads and reports their own result
If you have any of the symptoms of COVID-19, you should request a PCR test.
How Can I Protect Myself While Caring For Someone That May Have Covid
You should take many of the same precautions as you would if you were caring for someone with the flu:
- Stay in another room or be separated from the person as much as possible. Use a separate bedroom and bathroom, if available.
- Make sure that shared spaces in the home have good air flow. If possible, open a window.
- Wash your hands often with soap and water for at least 20 seconds or use an alcohol-based hand sanitizer that contains 60 to 95% alcohol, covering all surfaces of your hands and rubbing them together until they feel dry. Use soap and water if your hands are visibly dirty.
- Avoid touching your eyes, nose, and mouth with unwashed hands.
- Extra precautions:
- You and the person should wear a face mask if you are in the same room.
- Wear a disposable face mask and gloves when you touch or have contact with the person’s blood, stool, or body fluids, such as saliva, sputum, nasal mucus, vomit, urine.
- Throw out disposable face masks and gloves after using them. Do not reuse.
- First remove and throw away gloves. Then, immediately clean your hands with soap and water or alcohol-based hand sanitizer. Next, remove and throw away the face mask, and immediately clean your hands again with soap and water or alcohol-based hand sanitizer.

How Do I Know If I Have Covid
COVID-19 often causes symptoms similar to those a person with a bad cold or the flu would experience. And like the flu, the symptoms can progress and become life-threatening.
So far there has been much less than the usual number of cases of influenza, likely due to the enhanced public health measures to prevent the spread of COVID.
Therefore, at the current time, people with “flulike” symptoms should assume they have COVID. That means isolating and contacting your doctor or local board of health to arrange testing.
S To Take If You Had Close Contact With Someone With Covid
- Stay home and away from others unless you are not required to. Avoid contact with others to avoid spreading COVID-19.
- Do not go to work, school, or public areas. Do not take public transportation, taxis, or ride-shares.
- If you live with someone with COVID-19, stay separated from sick members in the household as much as possible. Avoid sharing the same space within the home, including being in the same room. Use a different bedroom or bathroom if that is possible.
- Yourlocal health department can help you make sure that your basic needs are being met.
- Monitor your health for 14 days after your last contact.
- Take your temperature with a thermometer two times a day and watch for fever. Also, watch for other symptoms of COVID-19, such as cough, shortness of breath, chills, muscle pain, sore throat, or new loss of taste or smell.
- Your local health department may ask you to check in with Sara Alert. Youll get a message from Sara Alert each day and answer a few questions about how youre feeling. If youre having COVID-19 symptoms, the health department will follow up with you. By checking in with Sara Alert, you can let the health department know how youre feeling and help to slow the spread of COVID-19 in your community. Learn more about How Sara Alert Works.

If Your Home Lfd Test Result Is Positive
If your LFD test was taken at home , you should self-isolate immediately. You and your household members should follow all this guidance. You should also arrange to have a follow-up PCR test as soon as possible. If the follow-up PCR test result is negative, you and your household contacts can stop self-isolating.
Where Do Coronaviruses Come From
Coronaviruses are viruses that circulate among animals. Some coronaviruses can infect humans.
Many human coronaviruses come from bats which are considered natural hosts of these viruses. The virus is then thought to be passed on through an intermediate host to humans. The first SARS-CoV originated in bats and was transmitted to humans via civet cats, while MERS-CoV emerged in humans through the intermediate host of camels. The precise way in which SARS-CoV-2 was transmitted from animals to humans is currently unknown.

Similar Peak Viral Loads
A study in medical journal The Lancet followed 602 primary close contacts of 471 people with COVID. It documented transmission and viral load in the group.
It found there were no differences in peak viral loads between vaccinated and unvaccinated individuals. It also showed only a small decrease in the number of infections in household members between vaccinated and unvaccinated people, suggesting a similar level of infectiousness.
Another unpublished pre-print, which is yet to be reviewed by other scientists, suggests a similar trend in viral load between vaccinated and unvaccinated people, as does a CDC report in the US from July which analysed outbreak data from Massachusetts.
The Massachusetts data came from a number of large public events over a two-week period in July in Barnstable County, Massachusetts. From 469 COVID cases, 346 occurred in fully vaccinated people. Viral load was similar in both vaccinated and non-vaccinated groups.
However, we shouldnt fear this analysis too much. The data reported is an imperfect representation of the population, and the measures they used a single swab and PCR test dont provide information about overall viral load over time.
How Long Will Covid Last Former Uk Leader Says Population Must Learn To Live With Covid
Former British Prime Minister Theresa May said on Monday that the U.K. government has to learn to live with COVID as variants such as the Omicron continue to appear.
May and other senior Conservative MPs have criticized the current COVID response, saying variants will continue to appear year after year so stopping and starting sectors of our economy is not an effective long-term strategy to maintain the nation’s safety and prevent its economy from collapsing.
The early indications of Omicron are that it is more transmissible, but potentially leads to less serious illness than other variants. I understand that would be the normal progress of a virus, May said. When is the government going to accept that learning to live with COVID, which we will all have to do, means we will almost certainly have an annual vaccine and that we cannot respond to new variants by stopping and starting sectors of our economy which leads to businesses going under and jobs being lost?
According to the Guardian, Conservative former cabinet minister Theresa Villiers also criticised the governments decision to impose new expensive requirements for international travel, while former transport secretary Chris Grayling urged health secretary Sajid Javid to face down the more conservative elements of the scientific community, do the right thing and keep the restrictions as minimal as possible.

What Is The Covid Fatality Rate
COVID-19 causes more cases of severe disease and more deaths than the seasonal flu. People over age 85 have the highest risk of fatality and children under 19 have the lowest, but this could change as more people are tested and trends become clearer for the variants. If, over time, widespread testing reveals milder, nonfatal cases of COVID-19, the death rate will go down.
What If I’ve Been Exposed But I’m Fully Vaccinated
Even fully vaccinated people who have been in close contact with someone who has COVID-19 should quarantine until they receive a negative test taken 3-5 days after exposure and have no symptoms.
Even if you receive a negative test during days 3-5 from exposure, please wear a mask at all times while indoors for a full 14 days. This is because fully vaccinated people can get develop COVID up to 14 days after exposure without having symptoms. If this happens, you are contagious and can spread the virus to other people.
These guidelines changed in June, 2021 because of the new COVID strain, Delta. Vaccinated people can spread the new Delta COVID variant to others even if they have no symptoms and do not feel ill. Please follow the guidance in the question above.

Cover Coughs And Sneezes
Cover your mouth and nose with disposable tissues when you cough or sneeze. If you do not have a tissue, cough or sneeze into the crook of your elbow, not into your hand.
Dispose of tissues into a rubbish bag and immediately wash your hands. If you have a carer, they should use disposable tissues to wipe away any mucus or phlegm after you have sneezed or coughed and then wash or sanitise their hands.
What Are The Symptoms Of Omicron Vs Delta
So far, people who have come down with COVID-19 from the omicron variant in the US appear to have mild symptoms.
Dr. Angelique Coetzee, a South African doctor who helped discover omicron, told the BBC that so far, patients she’s seen with the omicron variant have “extremely mild cases” of COVID-19. Those symptoms included fatigue, headache and a scratchy throat, she said, not the telltale loss of smell or a cough associated with earlier COVID-19 infections.
However, the delta variant may have slightly changed the way COVID-19 presents. Cough and loss of smell are also less common symptoms of COVID-19 caused by the delta variant compared with earlier variants, per the Baton Rouge General, a Mayo Clinic network. Cold symptoms like a headache and runny nose are now more common symptoms of COVID-19, according to the UK’s ZOE COVID Study.
In general, it’s too early to make a claim that omicron has milder or more severe symptoms than delta. Although anecdotal evidence shows that confirmed cases caused by omicron have shown mild symptoms, most of those people have been younger adults, according to South Africa’s health department. Younger adults and children are generally less likely to experience severe COVID-19 than older adults.

Will My Sense Of Taste And Smell Ever Return
I had Covid-19 symptoms back in March, and have yet to fully recover both senses. Do you have any suggestions on how I can get my smell and taste back, or could this be permanent? Alexandra Geca, fraud investigator, London
Loss of smell and taste are common features of Covid-19, affecting around 60% of those infected, and lasting for longer than a month in about 10% of cases. Some completely lose these senses, others report a partial loss, phantom smells, or a distorted sense of smell . Sometimes this is described as a smell of burning rubber, a pungent chemical smell or raw sewage, said Prof Carl Philpott, director of research and medical affairs for Fifth Sense, a charity supporting people with smell and taste disorders.
The good news is that parosmia is often a sign that your sense of smell is slowly returning and that the body is repairing any nerve damage caused by the virus.
Fifth Sense has developed a toolkit to help people rebuild their sense of smell through smell training, which involves doing regular and repetitive smell exercises. We encourage people to choose a range of smells that they are familiar with so that they will recognise any changes or improvements, and to use their other senses to support them, said Nina Bleasdale, Fifth Senses director of development and operations. For instance, you might grate an oranges skin to release its scent, as touching it, and using your memory of what an orange smells like.
When Do The First Covid
Not everyone who gets COVID-19 has symptomsin fact, the World Health Organization says 80% of infections are mild or asymptomatic. Yet those who do may develop fever and chills, a cough, muscle or body aches, fatigue, shortness of breath or difficulty breathing, or a loss of taste or smell. Other people with COVID-19 have reported headache, sore throat, congestion or runny nose, nausea or vomiting, and diarrhea.
The Centers for Disease Control and Prevention says symptoms may appear 2-14 days after exposure to the virus. Yes, thats a pretty large window. But a recent study by US immunologists, published in the Annals of Internal Medicine, narrowed it down. They analyzed more than 180 COVID-19 cases and found that, on average, it takes just over five days for COVID-19 symptoms to hit.
The research team also found that 97% of people who get the virus will develop symptoms within 11 days from the time they are first infected. Any of these symptoms can strike at any time during the course of the illness, from day one to the last days.

Are Clinically Recovered People Still Contagious
Sometimes, people will continue to test positive for COVID-19 for weeks after their symptoms have cleared. Health experts still dont know whyor exactly what that means for contagiousness.
“In some persons, after testing negative by RT-PCR in two consecutive samples, later samples can test positive again,” the CDC says. “Its not possible to conclude that all persons with persistent or recurrent detection of SARS-CoV-2 RNA are no longer infectious. There is no firm evidence that the antibodies that develop in response to SARS-CoV-2 infection are protective.”
A meta analysis of several studies found that people who have clinically recovered from COVID-19 do still have and can continue to shed SARS-CoV-2 RNA. However, researchers have questions about the accuracy of the diagnostic tests involved in these studies.
In Korea, researchers have observed that recovered patients can continue to have detectable SARS-CoV-2 RNA for up to 12 weeks following clinical recovery.
