Can I Get Or Spread Covid
When you get a COVID-19 vaccine, it teaches your immune system to recognize the virus as a foreign element and fight it. Studies show that COVID-19 vaccines can greatly reduce your chances of getting infected with the virus. But if you do catch it after youre vaccinated, the vaccine will still protect you from getting as seriously ill or needing hospitalization.
Its important to note that youre not optimally protected until 2 weeks after you get your second dose of a two-shot vaccine. Thats because it takes around 2 weeks for your body to build protection against the SARS-CoV-2 virus. And because the incubation period is shorter than the wait time between doses, its possible to catch COVID-19 before or just after your vaccination, since your body has not had enough time to build immunity. If this happens, the CDC recommends waiting until youve fully recovered to get the vaccine.
What Does Genetic Drift And Shift Of Influenza Mean
The influenza virus is antigenically unstable and new strains and variants are constantly emerging. Each year one or two subtypes of influenza A may be in circulation and one type of influenza B.
Antigenic drift Minor changes to the amino acid sequence of the haemagglutinin molecules in the virus envelope take place all the time and cause genetic drift. Haemagglutinin is the main antigen associated with immunity. Neuraminidase , the second main antigen in the virus plays a minor role in immunity. The drifted strains of influenza may infect partially immune people who have been exposed in previous winters. Influenza A drifts more than influenza B.
Antigenic shift Genetic shift occurs when major changes in the HA or NA take place and a virus emerges which contains a haemagglutinin different from those of previously circulating viruses. When this happens it gives rise to major epidemics or pandemics in populations throughout the world that have no immunity to the new strains, e.g. Spanish flu , Asian flu and Hong Kong flu . Influenza virus strains are classified according to the place and year in which they were first isolated. Many epidemics of influenza originate in South East Asia and are thought to be due to rare recombination events between human, avian and other animal strains of influenza following coinfection in a susceptible host.
When Am I Most Contagious
People with the flu are the most contagious during the first three to four days after symptoms begin.
|How long is the flu contagious?|
|1 day before symptoms develop||3-4 days after symptoms begin||5-7 days after symptoms begin|
|Start becoming contagious||Most contagious||Still contagious even if you feel completely better|
Note: This table is only a generalization. The CDC reports that young children and people with weakened immune systems may be contagious after seven days.
Symptoms of the flu can start to appear anywhere from one to four days after getting the flu virus, and even though most cases of the flu resolve in a week, symptoms can last up to several weeks for some people. Here are the most common symptoms of the flu:
- Runny nose

How Long Is The Incubation Period Of The Flu
There’s no exact time frame that’s the same for every person with the flu but, in general, the CDC says that the incubation period of the flu can range between one and four days, with the average length of time being two days.
People with the flu are the most contagious the first three to four days after they were infected, per the CDC, which can coincide with the incubation period. Most healthy adults may be able to infect others starting the day before they show symptoms, and continue to be infectious up to seven days after they become sick, the CDC adds.
“People have the flu and are out and about doing their regular stuff, coming into contact with others before they get sick,” Dr. Boling says. “You can infect plenty of people during that time.”
Will You Know If You’re In The Incubation Period For The Flu
Nope. “Generally, the flu is only recognized once symptoms develop,” Dr. Blutinger says. “The incubation period isn’t easily detected.”
Hindsight really is everything, Dr. Boling says: Once you develop symptoms of the flu, you have at least some clue of when your incubation period was.
The only way to really have a tip-off of when your incubation period is when you’re actually living through it is if you know you’ve been exposed to someone with the flu, Dr. Boling says. But, unfortunately, most people are infected without knowing it.
The bright side of all of this, if there even is such a thing, is that the proven methods to prevent the spread of COVID-19 also work to lower your risk of both contracting and passing on the flu. So, if you happen to catch the flu, wearing a mask while you’re out and about and practicing social distancing should go a long way toward making sure your incubation period doesn’t harm anyone else.

Can Someone Who Has Had Covid
Once the virus has left your system, you are no longer contagious.
Harvard Health studies have found that you are most contagious in the early stages of the disease, but you probably remain contagious for at least 10 days after you start to experience symptoms.
According to the CDC, if you develop symptoms of COVID-19, you should isolate yourself for at least 10 days after symptoms begin and until you have had no fever for at least 24 hours.
The only way to be sure youâre no longer spreading COVID-19 is to have two negative tests 24 hours apart.
Once you are negative for COVID-19, you are no longer contagious. It is also generally assumed that after 10 days, if you have not developed symptoms, you can be cleared to return to work or school.
Stomach Flu Incubation Period
The stomach flu, also known as gastroenteritis, is a common condition that affects many people across the country each year. This illness is commonly characterized by severe vomiting, abdominal pain and dehydration from an inability to effectively consume liquids. Stomach flu, however, is probably best known for its highly contagious nature.
In fact, people that develop the stomach flu can make other people in their household catch the illness as soon as theyre exposed to them. Despite how fast the stomach flu develops in people, the illness is known to have different incubation periods for most.

Can The Flu Be Prevented
There’s no guaranteed way to avoid the flu. But getting the flu vaccine every year can help. Everyone 6 months of age and older should get it each year.
Most doctor’s offices, clinics, and drugstores offer the flu vaccine from September to mid-November. It’s best to get it before the end of October. But even if you don’t get it at the start of the flu season, it’s not too late to get one while the flu is still going around.
If your child is sick, has a fever, or is wheezing, talk to your doctor to see if you need to reschedule the flu vaccine.
What Is Flu Season Or Seasonal Flu
The viruses that cause common flu or influenza circulate in the atmosphere throughout the year. But it becomes more activated or more likely to affect a person during the fall and winter seasons. That is why this particular season is known as the flu season, and the flu is called seasonal flu.

What Else Can Help
To make spreading the flu less likely, everyone in your family should::
- Wash hands well and often with soap, especially after using the bathroom, after coughing or sneezing, and before eating or preparing food
- Never pick up used tissues.
- Never share cups and eating utensils.
- Stay home from work or school if they have the flu.
- Cover their mouth and nose with a tissue when they cough or sneeze, then put it in the trash.
- Cough or sneeze into their upper arm, not their hands, if a tissue isn’t handy.
How Do You Prevent The Flu
The Centers for Disease Control recommends getting an annual flu vaccine as the best way to prevent the flu .
Flu vaccines will not prevent COVID-19, but they can reduce the burden of flu illnesses, hospitalizations, and deaths on the health care system and conserve medical resources to care for COVID-19 patients.
Please get immunized. Search pharmacies and clinics in your area free flu vaccines are offered all over the US.
To protect yourself from getting the flu:
- Wash hands frequently with soap and water for at least 20 seconds.
- If soap and water are not available, use hand sanitizer with at least 60% alcohol and use a sufficient amount to rub in for 20 seconds.
- Do not touch your mouth, nose, or eyes with unwashed hands.
- Avoid close contact with anyone who has been diagnosed with the flu.
- If there is an outbreak in your community, stay at home and limit close contact with others.

Which Are The First Symptoms Of Coronavirus Disease
Anyone can experience mild, moderate, or severe symptoms of the coronavirus disease, and the symptoms may hit all at once rather than gradually.
According to the Centers for Disease Control and Prevention , symptoms may appear 2-14 days after exposure to the virus and may include:
- New loss of smell or taste
- Congestion or runny nose
- Watery eyes or eye discharge
How Is The Flu Treated
Most kids with flu get better at home. Make sure your child:
- drinks lots of liquids to prevent dehydration
- gets plenty of sleep and takes it easy
- takes acetaminophen or ibuprofen to relieve fever and aches. Don’t give kids or teens aspirin because of its link to Reye syndrome.
- wears layers that are easy to remove. Kids might feel cold one minute and hot the next.
Children with the flu should stay home from school and childcare until they feel better. They should go back only when they haven’t had a fever for at least 24 hours without using a fever-reducing medicine. Some kids need to stay home longer. Ask the doctor what’s best for your child.
Doctors may prescribe antiviral medicine for a very ill child or kids are at risk for more serious symptoms. The medicine can shorten the flu by 12 days. It works best if children start taking it within 48 hours of the start of the flu. If a doctor prescribes antiviral medicine for your child, ask about any possible side effects. Doctors won’t prescribe antibiotics for the flu. Antibiotics work only against bacteria, not viruses.

How Can I Best Protect My Child Against The Flu
First, with your pediatricians OK, have your child vaccinated. Added prevention is also key. Teach your child how to wash his or her hands when he or she is in school or away from home with either soap and water or an alcohol-based hand rub.
The flu virus spreads mainly by droplets when infected people cough, sneeze, or even talk, but it can be spread by touching surfaces on which one of those droplets has landed and then touching ones nose, mouth or eyes. This is why hand washing is so important both for the person with the flu and others around him or her. If someone in your household has the flu, ask your doctor if preemptive antiviral medication is an option for others in the home. Clean common surfaces like the kitchen counter, bathroom sink, light switches, door knobs, etc., frequently with household disinfectants.
If your child has the flu, keep him or her home from school, daycare and any other activities that could expose others to the virus. If your child needs to go outside of the house, he or she should wear a mask to reduce the likelihood of spreading the virus to others.
We urge that children six months and older be vaccinated, especially those at risk for complications from the flu. Your childs pediatrician will know whats best for your child, especially if there are preexisting conditions, including allergies, that require careful review.
How To Deal With Flu
After the incubation period for flu, you will suffer from the flu and get others infected. So it is important to get it treated with home remedies and medications.
Home Remedies for Flu
- Drink plenty of liquids, such as juices, water and warm soups to keep yourself hydrated.
- Take plenty of rest to help your immune system clear the infection.
- Take OTC pain relievers such as ibuprofen or acetaminophen to alleviate the achiness associated with the flu. Young children should not have aspirin because it increases the risk of Rey’s syndrome.
Medication for Flu
You may have to use antiviral medication such as zanamivir or oseltamivir. You have to inhale zanamivir through a device, while oseltamivir is to be taken orally. Never take zanamivir if you have certain respiratory problems such as lung disease or asthma. These medications may produce some side effects such as vomiting and nausea. Taking these drugs with food may help reduce these side effects.

Incubation Period For Flu
Influenza is a viral infection that affects your throat, nose and lungs. Commonly called the flu, influenza isn’t the same as stomach flu viruses that produce symptoms such as vomiting and diarrhea. Most people recover from influenza on their own, but in some cases, it can lead to certain complications with life-threatening consequences. About 16 to 63 million people get influenza every year in the United States. Keep reading to learn more about flu and how it affects us.
What To Do If You Think You Have Covid
If youâre experiencing mild to moderate symptoms, you should stay home and avoid contact with other people until youâve gone at least 10 days without symptoms.
For treatment options, medications can be prescribed by a doctor that may help symptoms of COVID-19, but there is no official âcureâ. Symptomatic medications given by doctors include inhalers for shortness of breath and prescription cough/congestion medicines.
If you have a high-risk medical condition, you may be a candidate for COVID-19 antibody treatment as well, which is showing promise in outpatient treatment of mild COVID-19 symptoms. Your doctor may also recommend particular vitamins and other anti-inflammatory medications to help reduce the impact of the virus in your body.*
If you think you may have COVID-19 or have been exposed, our doctor can help with instructions on symptoms to watch for and how to protect others from the virus.
Seek emergency medical care if you experience severe symptoms of the coronavirus, such as:
- Persistent pressure or pain in the chest
- Difficulty breathing
- New confusion
Before going to the hospital, call ahead and alert them that you may have COVID-19 so that they can be prepared with proper protection and procedures.
You may need to enter through a separate entrance, for example, to limit the exposure risk to others.

What If You Test Positive Using An At
Those who test positive using an at-home test are asked to follow the latest CDC guidelines and communicate the results to their healthcare provider.
Arwady has said that that process is not likely happening for every test, however.
“All of those negatives realistically are not being reported,” Arwady said. “We’re not counting, you know, it’s a fiction that we’ve ever counted every COVID test.”
The at-home results are part of the reason Illinois’ health department changed the COVID metrics it tests.
With the state no longer reporting COVID case and test positivity, health officials said the reason is in part due to incomplete data due to at-home tests.
The department said the change, in part led by the fact that national testing data does not often reflect results from at-home tests, means that labs will no longer be required to report negative rapid antigen test results, though they will still need to show negative PCR and nucleic acid amplification test results.
Incubation Period For Stomach Flu
Stomach flu or viral gastroenteritis is an inflammation of the gastrointestinal tract that includes the stomach and the intestines. It is very contagious and affects millions of people every year. Read on to find out all information regarding the incubation period for stomach flu along with the various remedies to ease your discomfort.

Antivirals Can Help Even Before Symptoms Show
If you come down with the flu, antiviral drugs â such as oseltamivir , peramivir , zanamivir and baloxavir marboxil â can curb the severity of your flu symptoms, speed your recovery and reduce your risk for flu-related complications.
These medicines also reduce the level of flu virus in your respiratory secretions, making it less likely that you’ll spread the disease to others, even during the incubation period.
According to the CDC, oseltamivir and zanamivir are also 70 to 90 percent effective at averting development of flu symptoms if started right away after you’ve been exposed to someone with the flu and either haven’t gotten a flu shot or were vaccinated less than two weeks before exposure to the virus.
Although these antiviral drugs are highly effective in this setting, the CDC does not recommend their routine use except in certain situations, such as a flu outbreak in a nursing home or another long-term care facility, and in people with a weakened immune system or at high risk for flu complications.
