If you lot've been exposed to someone with COVID-19 or brainstorm to experience symptoms of the disease, you may be asked to cocky-quarantine or self-isolate. What does that entail, and what tin you lot practise to fix yourself for an extended stay at home? How presently later on you're infected will you start to be contagious? And what can you do to prevent others in your household from getting sick?

Symptoms of COVID-xix

What are the symptoms of COVID-19?

Some people infected with the virus have no symptoms. When the virus does cause symptoms, common ones include fever, body ache, dry cough, fatigue, chills, headache, sore throat, loss of appetite, and loss of smell. In some people, COVID-xix causes more astringent symptoms like high fever, severe cough, and shortness of jiff, which often indicates pneumonia.

People with COVID-nineteen can also experience neurological symptoms, gastrointestinal (GI) symptoms, or both. These may occur with or without respiratory symptoms.

For example, COVID-19 affects brain role in some people. Specific neurological symptoms seen in people with COVID-19 include loss of smell, disability to taste, musculus weakness, tingling or numbness in the hands and feet, dizziness, confusion, delirium, seizures, and stroke.

In addition, some people have gastrointestinal (GI) symptoms, such equally loss of appetite, nausea, airsickness, diarrhea, and abdominal pain or discomfort associated with COVID-19.

What should I practice if I think I or my kid may have a COVID-19 infection?

Get-go, call your doctor or pediatrician for advice.

If you do non have a doctor and you are concerned that you or your child may take COVID-19, contact your local board of wellness. They can direct you to the all-time place for testing and treatment in your area. Over-the-counter tests may likewise be available at your local pharmacy or grocery store.

If y'all do test positive and either take no symptoms or tin can recover at home, you will withal need to

isolate at home for 5 days
if yous have no symptoms or your symptoms are improving after five days, you lot can discontinue isolation and leave your home
proceed to wear a mask around others for five additional days.

If you take a fever, continue to isolate at dwelling until y'all no longer accept a fever.

If yous have a high or very low trunk temperature, shortness of breath, confusion, or feeling you might pass out, yous need to seek immediate medical evaluation. Telephone call the urgent care center or emergency section ahead of fourth dimension to let the staff know that you are coming, then they tin can be prepared for your arrival.

How do I know if I have COVID-19, the flu, or just a cold?

Now that the Omicron variant of COVID-19 is the dominant strain, telling the difference is more challenging than always. Fifty-fifty if you have been vaccinated and boosted, you can still get symptoms, but they are likely to exist mild to moderate in severity. For those not vaccinated, the risk of astringent symptoms that can be life-threatening is still substantial.

At the current time, people with "flulike" symptoms should assume they have COVID. If possible, arrange to get tested or practise a home test. If the test is positive, y'all should isolate at home for v days. If yous had a negative test when symptoms started, information technology'due south still all-time to isolate at home for two to 3 more days, to monitor your symptoms and prevent spreading infection. (That'due south because there is a chance of simulated negatives with antigen tests, which means y'all tin yet accept COVID with a negative test.) Consider testing again earlier going out. One time you are ready to leave home, keep to consistently wear a mask for at least five more than days.

COVID-19 Testing

I recently spent fourth dimension with someone who tested positive for COVID-19. I'm fully vaccinated and boosted. Do I demand to get tested?

Co-ordinate to the latest CDC guidelines, if you are vaccinated and additional, or have gotten your initial vaccine series within the last half-dozen months (for Pfizer/BioNTech or Moderna) or the final 2 months (for Johnson & Johnson), y'all should wear a mask around others for 10 days and take a COVID exam on day v, if possible. If you develop symptoms, get tested sooner and isolate at home.

If you are unvaccinated, had your final Pfizer or Moderna shot more than six months ago and accept not been additional, or had your Johnson & Johnson bear witness more than two months ago and have not been boosted, you should stay domicile for five days and vesture a mask around others for an additional five days. If you tin't quarantine, wearable a mask around others for 10 days. Get tested for COVID on day 5, if possible. If yous develop symptoms at whatever time, get tested and isolate at home.

What is the divergence between a PCR exam and an antigen examination for COVID-19?

PCR tests and antigen tests are both diagnostic tests, which means that they can be used to determine whether you lot currently accept an active coronavirus infection. All the same, there are important differences between these 2 types of tests.

PCR tests discover the presence of the virus's genetic textile using a technique chosen reverse transcriptase polymerase concatenation reaction, or RT-PCR. For this test, a sample may be nerveless through a nasal or pharynx swab, or a saliva sample may be used. The sample is typically sent to a laboratory where coronavirus RNA (if nowadays) is extracted from the sample and converted into Dna. The Deoxyribonucleic acid is and then amplified, meaning that many copies of the viral DNA are made, in order to produce a measurable upshot. The accuracy of any diagnostic test depends on many factors, including whether the sample was nerveless properly, when during the course of affliction the testing was washed, and whether the sample was maintained in appropriate conditions while it was shipped to the laboratory. By and large speaking, PCR tests are highly authentic.

Antigen tests discover specific proteins on the surface of the coronavirus. They are sometimes referred to every bit rapid diagnostic tests because it can accept less than an hour to go the test results. Positive antigen test results are highly specific, meaning that if you test positive you lot are very likely to exist infected. All the same, in that location is a college chance of false negatives with antigen tests, which means that a negative upshot cannot definitively rule out an active infection. If you lot have a negative result on an antigen test, your md may gild a PCR test or a second rapid antigen test to confirm the result.

It may exist helpful to think of a COVID antigen examination as you would call back of a rapid strep examination or a rapid influenza test. A positive event for any of these tests is likely to be accurate, and allows diagnosis and treatment to begin chop-chop, while a negative result often results in farther testing to confirm or overturn the initial result.

How reliable are the tests for COVID-19?

2 types of diagnostic tests are currently available in the US. PCR tests detect viral RNA. Antigen tests, also called rapid diagnostic tests, detect specific proteins on the surface of the coronavirus. Antigen test results may come back in as little as 15 to 45 minutes; you may look several days for PCR test results.

The accuracy of any diagnostic test depends on many factors, including whether the sample was collected properly. For PCR tests, which are typically analyzed in a laboratory, exam results may exist affected by the atmospheric condition in which the test was shipped to the laboratory.

Results may also exist afflicted by the timing of the test. For example, if you are tested on the solar day you were infected, your test event is almost guaranteed to come dorsum negative, because in that location are not yet enough viral particles in your nose or saliva to detect. The chance of getting a false negative test issue decreases if you are tested a few days afterwards you were infected, or a few days after you develop symptoms.

Mostly speaking, if a exam effect comes back positive, it is nearly sure that the person is infected.

A negative test result is less definite. There is a higher risk of false negatives with antigen tests, and early on data suggests that antigen tests may be even more likely to miss the Omicron variant. If you lot have a negative result on an antigen examination, your dr. may lodge a PCR test or recommend a 2d rapid antigen test to ostend the event.

If you experience COVID-like symptoms and become a negative PCR test result, there is no reason to repeat the exam unless your symptoms get worse. If your symptoms exercise worsen, telephone call your doctor or local or state healthcare department for guidance on further testing. Yous should as well self-isolate at home. Habiliment a mask when interacting with members of your household. And practice physical distancing.

What is serologic (antibody) testing for COVID-xix? What can it be used for?

A serologic examination is a blood test that looks for antibodies to SARS-CoV-2 created by your immune system in response to infection or vaccination.

Your trunk takes 1 to three weeks afterward you lot have acquired the infection to develop antibodies to this virus. For this reason, serologic tests are not sensitive enough to accurately diagnose an active COVID-19 infection, even in people with symptoms.

Antibodies and Spreading COVID-nineteen

I've heard that the allowed system produces different types of antibodies when a person is infected with the COVID-19 coronavirus. How practise they differ? Why is this important?

When a person gets or is vaccinated against a viral or bacterial infection, a healthy immune arrangement makes antibodies against one or more components of the virus or bacterium.

The COVID-nineteen coronavirus contains ribonucleic acid (RNA) surrounded by a protective layer, which has spike proteins on the outer surface that can latch on to sure human cells. Once inside the cells, the viral RNA starts to replicate and as well turns on the production of proteins, both of which let the virus to infect more than cells and spread throughout the body, especially to the lungs.

While the immune system could potentially respond to unlike parts of the virus, it's the fasten proteins that go the near attention. Immune cells recognize the spike proteins as a foreign substance and begin producing antibodies in response.

There are two primary categories of antibodies:

Binding antibodies. These antibodies tin can bind to either the spike protein or a different poly peptide known equally the nucleocapsid poly peptide. Binding antibodies can be detected with claret tests starting about one calendar week afterwards the initial infection. If antibodies are institute, information technology's extremely likely that the person has been infected with the COVID-xix coronavirus. The antibody level declines over time after an infection, sometimes to an undetectable level.

Binding antibodies assistance fight the infection, but they might not offer protection against getting reinfected in the future. Information technology depends on whether they are also neutralizing antibodies.

Neutralizing antibodies. The body makes neutralizing antibodies that attack the coronavirus's fasten protein, making it more than hard for the virus to attach to and enter man cells. Neutralizing antibodies provide more than lasting protection than binding antibodies against reinfection.

Monoclonal antibodies are manmade versions of neutralizing antibodies. The FDA has authorized monoclonal antibody treatments for certain groups of COVID-19 patients.

Tin a person who has been infected with coronavirus get infected again?

The allowed system responds to COVID-19 infection by stimulating white blood cells chosen lymphocytes to class antibodies that fight the infection. These antibodies and lymphocytes retain a temporary protective effect against reinfection. Merely it is only temporary. At that place have been many confirmed cases of reinfection with COVID-19. In other words, a person got sick with COVID-19, recovered, and then became infected again.

This has been especially truthful equally the coronavirus has mutated into COVID-19 variants. In that location was a ascent in reinfections with the Delta variant, and an explosive increase in the reinfection rate due to the Omicron variant. Omicron has near 50 mutations, including more than thirty mutations on the spike poly peptide, the region of the virus that our immune systems recognize after previous infection. Considering of this, Omicron is more capable than previous variants of evading our immune defenses and causing reinfection.

We take learned that vaccination plus a booster dose strengthens the natural immune response, fifty-fifty in those who have been previously infected, and farther reduces the hazard of reinfection. Although breakthrough infections later vaccination are also more common with Omicron than previous variants, vaccination continues to protect well against severe illness.

The bottom line? Get vaccinated and additional whether or not you've already had COVID-xix.

Contagiousness of COVID-19

How shortly after I'one thousand infected with the new coronavirus volition I showtime to be contagious?

The time from exposure to symptom onset (known every bit the incubation period) is thought to be two to 14 days. Symptoms typically appeared inside five days for early variants, and within four days for the Delta variant. The incubation period appears to exist even shorter – about three days – for the Omicron variant.

We know that people tend to be most infectious early in the grade of their infection. With Omicron, most transmission occurs during the i to 2 days earlier onset of symptoms, and in the two to iii days afterwards.

Wearing masks, peculiarly indoors, tin can help reduce the risk that someone who is infected but not withal experiencing symptoms may unknowingly infect others.

Tin can people without symptoms spread the virus to others?

"Without symptoms" can refer to two groups of people: those who eventually exercise accept symptoms (pre-symptomatic) and those who never go on to have symptoms (asymptomatic). During this pandemic, we have seen that people without symptoms can spread the coronavirus infection to others.

A person with COVID-19 may be contagious 48 hours earlier starting to feel symptoms. In fact, people without symptoms may exist more probable to spread the disease, considering they are unlikely to exist isolating and may not prefer behaviors designed to preclude spread.

Only what about people who never go on to develop symptoms? A report published inJAMA Network Open found that almost ane out of every four infections may be transmitted by individuals with asymptomatic infections. The proportion of asymptomatic transmission appears to be fifty-fifty college with the Omicron variant.

Getting vaccinated and boosted once you lot are eligible is important for protecting not just yourself but others also; evidence suggests that you're less likely to infect others, or may be contagious for a shorter period of time, once y'all've been vaccinated.

For how long after I am infected will I continue to be contagious? At what betoken in my disease volition I be well-nigh contagious?

People are thought to be well-nigh contagious early in the course of their illness. With Omicron, virtually transmission appears to occur during the one to two days before onset of symptoms, and in the ii to three days later. People with no symptoms tin too spread the coronavirus to others.

By the tenth day afterwards COVID symptoms begin, nearly people will no longer be contagious, equally long as their symptoms have continued to improve and their fever has resolved. People who test positive for the virus only never develop symptoms over the following 10 days subsequently testing are also probably no longer contagious.

The CDC's isolation guidelines, updated in December 2021, reflect this knowledge. According to the guidelines, everyone who tests positive for COVID-19 should

isolate at habitation for five days
if you have no symptoms or your symptoms are improving later on 5 days, you can discontinue isolation and leave your home
continue to clothing a mask around others for v additional days.

If y'all accept a fever, go on to isolate at home until you no longer have a fever.

I'grand vaccinated merely got a breakthrough COVID infection. Can I still spread the infection to others?

Yes, you can. That's why the CDC recommends that anybody who tests positive for COVID-19 should isolate from others for at to the lowest degree v days, regardless of their vaccination status.

How tin can I protect myself while caring for someone that may have COVID-19?

Yous should have many of the same precautions as you would if you were caring for someone with the flu:

Stay in some other room or exist separated from the person as much equally possible. Use a split up bedchamber and bath, if bachelor.
Make sure that shared spaces in the home take good air flow. If possible, open a window.
Launder your hands oft with soap and water for at to the lowest degree xx seconds or utilise an alcohol-based hand sanitizer that contains sixty to 95% alcohol, roofing all surfaces of your easily and rubbing them together until they experience dry out. Use soap and water if your hands are visibly muddy.
Avoid touching your eyes, nose, and mouth with unwashed hands.
You lot and the person should vesture a confront mask if you are in the same room.
Wear a dispensable face mask and gloves when you touch or have contact with the person'southward blood, stool, or body fluids, such equally saliva, sputum, nasal mucus, vomit, urine.
- Throw out disposable face masks and gloves afterward using them. Do not reuse.
- First remove and throw away gloves. Then, immediately clean your hands with soap and water or alcohol-based manus sanitizer. Side by side, remove and throw away the confront mask, and immediately clean your hands again with soap and water or alcohol-based paw sanitizer.
Do not share household items such as dishes, drinking glasses, cups, eating utensils, towels, bedding, or other items with the person who is sick. After the person uses these items, wash them thoroughly.
Clean all "high-touch" surfaces, such as counters, tabletops, doorknobs, bathroom fixtures, toilets, phones, keyboards, tablets, and bedside tables, every twenty-four hours. Also, clean any surfaces that may have blood, stool, or torso fluids on them. Use a household cleaning spray or wipe.
- Wash laundry thoroughly.
- Immediately remove and wash apparel or bedding that have claret, stool, or body fluids on them.
Wear disposable gloves while treatment soiled items and continue soiled items abroad from your trunk. Make clean your hands immediately after removing your gloves.
Identify all used disposable gloves, face up masks, and other contaminated items in a lined container before disposing of them with other household waste. Clean your easily (with soap and h2o or an booze-based hand sanitizer) immediately afterward handling these items.

Can people infect pets with the COVID-19 virus?

The virus that causes COVID-19 does appear to spread from people to pets, according to the FDA, though this is uncommon. Research has constitute that cats and ferrets are more probable to become infected than dogs.

If y'all get sick with COVID-19, information technology'due south best to restrict contact with your pets, just like you would around other people. This means yous should forgo petting, snuggling, being kissed or licked, and sharing food or bedding with your pet until you are feeling better. When possible, take some other member of your household care for your pets while you are sick. If you must care for your pet while you lot are ill, launder your hands before and after y'all interact with your pets and wear a face mask.

At present, it is considered unlikely that pets can spread the COVID-19 virus to humans. Even so, pets can spread other infections that cause illness, includingDue east. coli and Salmonella, and then wash your hands thoroughly with soap and water after interacting with your animal companions.

Long Term Effects of COVID-19

I had COVID-xix a few months agone. Am I at increased adventure for health problems in the hereafter?

It does appear that people who recover from COVID-19 take an increased run a risk of developing other medical conditions, at least in the short term.

One study, published inThe BMJ, collected laboratory examination and hospital admissions data from a health plan in the United states of america. The researchers compared data from more than 190,000 adults, ages 18 to 65 years, who tested positive for the SARS-CoV-ii virus in 2020, to information from a control group that was collected in 2019, before the pandemic. The researchers followed the participants for six months later on they tested positive for SARS-CoV-2 and recorded any new health complications.

They found that xiv% of people who had had COVID-nineteen adult a new medical issue during the following six months; this was most 5% higher than the pre-pandemic command group, a significant difference. New medical issues affected a range of body systems and included respiratory failure, abnormal heart rhythms, diabetes, neurological problems, and liver and kidney problems. Increased risk was seen in younger, previously healthy people, but was higher in older people and those with pre-existing medical problems.

Another study, published inNature, compared the health records of more than 73,000 users of the Veteran's Health Administration (VHA) who tested positive for SARS-CoV-2 but were never hospitalized, to those of well-nigh v one thousand thousand other VHA users who never tested positive for COVID-nineteen and were never hospitalized. For six months post-obit the commencement 30 days after infection, people who had had COVID-19 were significantly more than probable to die or to feel a medical or mental health problem that they had never had earlier.

These studies provide yet some other reason to go vaccinated and boosted if you are eligible.

Who are long-haulers? And what is mail-viral syndrome?

Long haulers are people who have non fully recovered from COVID-19 weeks or even months subsequently get-go experiencing symptoms. Some long haulers experience continuous symptoms for weeks or months, while others feel better for weeks, and then relapse with old or new symptoms. The constellation of symptoms long haulers experience, sometimes called mail service-COVID-xix syndrome or mail-acute sequelae of SARS-CoV-2 infection (PASC), is not unique to this infection. Other infections, such as Lyme disease, tin can cause similar long-lasting symptoms.

Emerging research may help predict who will become a long hauler. One study plant that COVID-xix patients who experienced more than than five symptoms during their showtime week of illness were significantly more likely to get long haulers. Certain symptoms — fatigue, headache, difficulty breathing, a hoarse voice, and muscle or body aches — experienced lone or in combination during the first week of illness also increased the chances of condign a long hauler, as did increasing age and higher torso mass index (BMI).

Though these factors may increase the likelihood of long-term symptoms, anyone can go a long hauler. Many long haulers initially accept mild to moderate symptoms — or no symptoms at all — and do not crave hospitalization. Previously healthy young adults, non just older adults with coexisting medical weather, are also experiencing post-COVID-19 syndrome.

Symptoms of post-COVID-xix syndrome, like symptoms of COVID-xix itself, can vary widely. Some of the more mutual lasting symptoms include fatigue, worsening of symptoms subsequently concrete or mental activity, brain fog, shortness of breath, chills, trunk ache, headache, articulation pain, chest hurting, coughing, and lingering loss of taste or odor. Many long haulers report cognitive dysfunction or memory loss that affects their solar day-to-24-hour interval ability to do things like make decisions, have conversations, follow instructions, and drive. The mutual thread is that long haulers haven't returned to their pre-COVID wellness, and ongoing symptoms are negatively affecting their quality of life. A systematic review published in JAMA Network Open reported that more than half of people infected with COVID-19 continued to experience at to the lowest degree one symptom six months afterward their diagnosis.

There's already some speculation, just no definite answers, about what is causing these ongoing symptoms. Some researchers suspect that SARS-CoV-2 infection triggers long-lasting changes in the immune organization. Others propose that information technology triggers autonomic nervous system dysregulation, which tin can impact eye rate, claret pressure, and sweating, amid other things.
