How Long Are You Contagious With The Flu?

When am I no longer contagious with the flu?
Is the Flu Contagious? – The flu is very contagious. People can spread it from a day before they feel sick until their symptoms are gone. This is about 1 week for adults, but it can be longer for young kids. The flu usually happens in annual epidemics. An epidemic is when an illness spreads quickly and infects lots of people in an area at the same time.
How do you know when the flu is gone?
Flu Stages: Recovery Day-by-Day In general, the stages of recovery follow a relatively predictable timeline. Symptoms tend to develop one to two days after exposure to the and last for between five to seven days. Older people or people with may take longer to recover, while young, healthy people may take longer for symptoms to develop.
Understanding the stages of the flu—including the that are likely to develop—can help you decide if you are recovering as you should. It can also help you figure out if you are still and able to infect others. This article describes the stages of flu from day 0 to day 8. You will also learn which flu symptoms occur at which stage, when you are no longer contagious, and what you can do to feel better as the flu progresses.
Day 0 is the stage when you get the virus. Infection occurs when a person with flu coughs, sneezes, or talks, propelling into the air that are breathed into your mouth or nose. It is also possible to get flu by and then your nose, eyes, or mouth. At this stage, you will feel fine and be entirely unaware that you are about to get sick within the next day or two.
- Even so, you are technically contagious on Day 0.
- The amount of virus in the of the may not yet be at transmittable levels, but that can change with each passing hour as the virus starts to rapidly multiply in your nasal passages and throat.
- Day 1 is when the body mounts an aggressive,
- It does so by releasing proteins called that coordinate the immune attack and trigger,
Inflammation helps neutralize the virus but also causes uncomfortable symptoms like heat, swelling, and pain. At the start of Day 1, you may wake up feeling fine but progressively feel worse as the day goes on. By the end of the day, you may start developing the tell-tale early signs of flu, including:
- Headache
- Sudden high fever
- Chills
As soon as realize you have the flu, call your healthcare provider about that may help reduce the severity of the infection. This is especially true if you have or are at, Options include:
- Rapivab (peramivir)
- Relenza (zanamivir)
- Tamiflu (oseltamivir phosphate)
- Xofluza (baloxavir marboxil)
Flu antivirals are most effective when they are started within 48 hours of the first signs of infection. Day 2 is when flu symptoms have fully taken hold, extending from the upper respiratory tract—including the nostrils, nasal cavity, mouth, (throat), and (voice box)—to the (windpipe).
- High fever with chills
- Cough
- Sore throat
- Runny or stuffy nose
- Muscle or body aches
- Headaches
- Fatigue
If you have flu, the Centers for Disease Control and Prevention (CDC) recommends that you stay at home for at least 24 hours after your fever is gone, except to get medical care or other necessities. Day 3 is often described as the worse stage of the flu.
- This is the day when many symptoms are at their most intense.
- Inflammation of the nasal passages and pharynx can cause severe congestion and sore throat.
- Persistent high fever can make it difficult to even lift your head.
- The inflammation spreading from the trachea to the (the main airways of the lungs) will cause an intense, generally dry () cough at this stage.
In small children especially, vomiting or diarrhea can occur. Call 911 or have someone rush you to the nearest emergency room if you develop the following signs of flu complications:
- Difficulty breathing or shortness of breath
- Persistent pain or pressure in the chest
- Persistent dizziness
- Confusion
- Difficulty staying awake or being aroused from sleep
- Severe muscle pain
- Severe weakness or unsteadiness
- Fever or cough that improves but then returns or worsens
- Seizures
- Not urinating
Day 4 is generally the turning point in the infection. At this stage, the immune system will have gained control over the virus. You may start to feel a little better but probably too weak to do anything but sleep. Your fever will likely have broken, and you shouldn’t have as many body aches.
Any congestion should start to loosen as well. Even so, the aftermath of the infection can manifest with other symptoms. The massive inflammation in the trachea and bronchi can cause the overproduction of mucus that begins to clog the lungs. When this happens, the dry cough may become more chesty and wet () and get worse rather than better.
Even if your fever has broken, it is important to stay in bed and get plenty of fluids. By the end of the day, you may start to feel worse again and your fever may return. Day 5 is the stage where active recovery begins. While the infection itself will be mostly clear, there may still be some underlying inflammation, which is perfectly normal.
This is because inflammation not only defends the body against infection but also starts the healing process by increasing blood flow to injured tissues. At this stage, your fever should be gone. You should also have less congestion but will still likely have a cough. You may even find yourself coughing up or becoming hoarse from all of the coughing.
If you are not starting to feel better by Day 5 or find that your symptoms are getting worse, call your healthcare provider. Day 6 is when you should be well enough to get out of bed. There may still be some residual coughing, but breathing will be easier and the fever should be entirely gone.
- While you may feel well enough to go back to work, the CDC advises against this until you have been fever-free for at least 24 hours without taking any,
- People with the flu may be contagious anywhere from one day before to seven days after the appearance of flu symptoms.
- Day 7 is the stage when most people can confidently go out into public.
Even so, you should continue to take standard precautions to protect others around you. Cover your mouth while coughing and sneeze into a tissue or the crook of your elbow. Wash your hands immediately after, and disinfect any surfaces with a general-purpose cleaner.
With that said, Day 6 or 7 is the time when certain people start to develop (inflammation of the bronchi). This may be caused when the lingering virus moves into the lungs. Less commonly, it is caused by a in which bacteria enter airways that have been weakened by the flu. While most cases of acute bronchitis are relatively mild, they can cause a lingering wet cough that persists for weeks.
Severe cases should be seen by a healthcare provider. Other people have been known to develop (a middle ear infection) after the flu, also typically mild. Day 8 is typically the “all-clear” day for most people, including children. Most people should be well on their way to recovery and will likely no longer be contagious.
- Even most older adults should be fine by this stage, though it may take them longer to fully recover.
- Don’t be distressed if you feel out of sorts and have a lingering cough for another week.
- This is not uncommon.
- If you are used to exercising regularly, you should be —just don’t go overboard.
- Your body is still recovering and can tire easily.

Flu symptoms tend to develop one to two days after exposure to the virus and last for between five to seven days. Day 1 to Day 3 are characterized by the abrupt onset and worsening of symptoms. Day 5 to Day 6 is when most people start to feel notably better.

Should I sleep with my wife if she has the flu?
Avoid sharing common spaces and personal items – When someone you love is sick, your first instinct may be to comfort and spend more time than usual with him or her. But, in reality, you should probably do the opposite. When someone in your home is sick, it’s important that he or she stays away from others, including you, as much as possible.
Ideally, the person who’s sick should stay in a separate room and use a separate bathroom, when possible. You should also avoid sharing everyday items, including towels, bedding and dishes. Lastly (and this is important), the person who is sick should not be the one cooking meals for the rest of the healthy household.
Some viruses require extra precautions. If you share a home with someone who has COVID-19, he or she should wear a — especially if avoiding common spaces is challenging due to the size of your home. A cloth mask doesn’t completely prevent a person from spreading COVID-19, but it can help reduce the risk.
How does the flu usually end?
Symptoms – Flu symptoms often start quickly. You can start to feel sick about 1 to 7 days after you come in contact with the virus. Most of the time, symptoms appear within 2 to 3 days. The flu spreads easily. It can affect a large group of people in a very short amount of time.
Body achesChillsDizzinessFlushed faceHeadacheLack of energyNausea and vomiting
The fever, aches, and pains begin to go away on days 2 through 4. But new symptoms may occur, including:
Dry coughIncreased symptoms that affect breathingRunny nose (clear and watery)SneezingSore throat
Most symptoms go away in 4 to 7 days. The cough and tired feeling may last for weeks. Sometimes, the fever comes back. Some people may not feel like eating. The flu can make asthma, breathing problems, and other long-term (chronic) illnesses and conditions worse.
Why do some people not catch flu?
Why some people don’t get the flu Why do some people end up in bed feverish, hacking and sneezing for days from the flu — when others seem to never get sick? To answer that question, University of Michigan researchers did the first study of its kind: They infected 17 healthy people with the flu virus and discovered that everyone who is exposed to the flu actually is affected by it, but their bodies just have a different way of reacting to it.
- Half of the study participants got sick; the other half didn’t notice a thing.
- Many people might conclude that if you are exposed to a virus and you don’t get sick, it’s because the virus didn’t stick or it was so weak, it just passed right through your system and your system didn’t notice.
- That’s not a correct notion,” says Alfred Hero, professor at the University of Michigan College of Engineering and author of the study, which was published Thursday in the journal PLoS Genetics.
He continues, “There is an active immune response which accounts for the resistance of certain people getting sick, and that response is just as active as the response we all know and hate, which is being sick with the sniffles, fever, coughing and sneezing.
It’s just that the responses are different.” Hero, along with scientists from Duke University Medical Center and the Duke Institute for Genome Sciences & Policy, studied participants’ gene expression to watch how the immune system reacted to the flu virus. The analysis reviewed 22,000 genes and 267 blood samples, and used a pattern recognition algorithm and several other methods to discover the genomic signatures associated with the immune response in people who get flu symptoms and those who do not.
They found significant and complex immune responses in the people who got sick and the people who didn’t. Scientists noticed changes in their blood 36 hours before some people actually felt sick. Although they understand that some people’s immune systems resist the virus, they still don’t know how or why that happens.
“There is a behind the scene active immune response even when you don’t get sick,” Hero says. “What we found were differences in their biological metabolism and gene expression. These differences had to do with antioxidants.” Eventually, if scientists can understand what happens at the level of the genome that makes people more or less susceptible to viral illness, they could potentially develop therapies to prevent the illness.
Lamar Johnson, 44, of Minneapolis, says he’s often wondered if drinking several glasses of juice daily and eating loads of fresh produce keeps him healthy — because in the dead of winter, when everyone around him seems to be suffering from the flu, he never gets sick.
- In fact, he doesn’t believe he’s ever had the flu in his life.
- I just stay out of the cold, do my best to stay away from sick people and hope I don’t get sick,” he says.
- Indeed, Hero says drinking juice, and eating fresh fruits and vegetables to load up on antioxidants may be the answer to avoid getting sick with the flu.
“It’s certainly possible that people who came in had a very high level of antioxidant precursors in their blood, and this may what protected them, but we’re not saying that because we don’t know. You can’t go beyond the data to make these hypotheses.” Researchers know the flu can be deadly.
The Centers for Disease Control and Prevention reports that of the 15 million to 60 million Americans that get the flu each year, and 5,000 to 45,000 die from it. About 200,000 people end up in the hospital with the flu each year. Hero says his research could lead to an inexpensive test people could take to tell if they are going to have flu symptoms 36 hours in advance.
Hero says, “That way people would know if they need to take time off, cancel their ski vacation or isolate themselves from their grandparents who are very susceptible.” : Why some people don’t get the flu
Is it bad to lay in bed all day when sick?
When you’re sick, you may find yourself dozing in bed or on the couch all day. It can be frustrating, but it’s normal to feel tired and lethargic when you’re sick. In fact, sleeping when you’re sick is essential. It’s one way your body tells you to slow down and rest, so you can get healthy.
- Read on to learn more about exactly how sleep boosts your immune system and how you can get a good night’s rest even with a cough or stuffy nose,
- Sleep gives your body time to repair itself, which you need when you’re sick.
- When you get sleepy, it forces you to slow down and give your body the time it needs to heal.
There are also certain immune processes that take place while you sleep that can bolster your body’s ability to fight off an illness. If you get sleepy when you’re feeling under the weather, it may be your body’s way of trying to let those processes kick in.
Fighting an illness also takes a lot of energy, which can make you feel tired and lacking in energy. Most benefits of sleep when you’re sick are related to helping your immune system do its job and fight your illness. This happens in a few different ways. First, cytokines, which are a type of protein in your immune system that target infections, are produced and released during sleep.
This means that sleep helps jump-start your immune response to your illness. Your body also has a better fever response — which is another way it fights infection — while you’re sleeping. Your immune system also needs energy to function. When you’re awake, your body needs to direct energy to activities like thinking or moving around.
If you’re sleeping, your body can redirect that energy to your immune system so you can get better as quickly as possible. Being tired also means that you’re less likely to go out and infect others while you’re sick. A lack of energy can also help keep you safe. Because your immune system is busy fighting the infection you have, it doesn’t fight as well against any new potential illnesses.
So, feeling tired can prevent you from going out and exposing yourself to other germs and diseases. And since research suggests that lack of sleep can make you more susceptible to getting sick, staying inside and getting extra sleep has an even stronger positive effect on your health.
- If you’re sleeping a lot when you have a cold, flu, or fever, it’s because your body needs the rest.
- Sleeping more than usual is helping your body build up its immune system and fight off your illness.
- If you find yourself sleeping all day when you’re sick — especially during the first few days of your illness — don’t worry.
As long as you wake up to drink water and eat some nourishing food from time to time, let your body get all the rest it needs. If, however, your cold, flu, or illness doesn’t seem to get better with time, even with plenty of rest, be sure to follow up with your doctor.
- Also, if your illness gets better, but you’re still exhausted or lethargic, it’s a good idea to see your doctor to determine the cause.
- Even though being sick can make you tired, it can be hard to get quality sleep when you don’t feel well or have a stuffy nose or persistent cough.
- In many cases, symptoms tend to get worse later in the day, which can make sleep even more difficult.
If you’re having a hard time sleeping, try some of these tips: Sleeping when you’re sick is essential for your recovery. Sleep helps to boost your immune system, so you can fight off your illness more effectively. Your body knows what it needs, so don’t worry if you find yourself sleeping a lot when you’re sick, especially in the first few days.
Why did my husband get the flu and I didn t?
In a new study, scientists at Fred Hutchinson Cancer Research Center show that a single mutation in a flu virus can sometimes give it the power to evade 90% of one person’s antibody immunity, but not another’s.
Are you contagious without a fever cold?
You’re generally contagious with a cold 1-2 days before your symptoms start, and you could be contagious as long as your symptoms are present—in rare cases, up to 2 weeks. The contagious period for the flu can last as long as 5-7 days from when you first felt sick.
Will I get the flu if my wife has it?
The germs that cause influenza are spread up to three feet when someone who has the flu coughs or sneezes. You can even spread flu germs when you speak. If you handle things the germs land on and then touch your eyes, nose or mouth, the flu virus can easily enter your body.
Can I go down on my wife if I have a cold?
Is it safe to have oral sex when you have cold and cough? Find out here. – I am a 35-year-old married man and I love performing oral sex on my wife. She loves doing the same for me too. But I recently caught a cold and had a cough and still performed oral sex on her.
We did not have sex, and I made sure I did not kiss her. Is it possible for her to catch a cold this way? The short answer to that is no. It is not possible. Here’s why. The virus that causes a cold and cough does not transmit through the type of skin present in a person’s genitals. It does however transmit through the mucosal lining present in the nose, mouth and eyes.
So if you kiss your wife, she touches something infected with your spit or mucus and then touches her mouth, eyes or nose with the same hand, then she is likely to catch a cold and cough. That being said, a number of STD (Sexually Transmitted Diseases) can be transmitted by performing unprotected oral sex.
These STDs often mimic a cold and sore throat. Therefore, if you have been noticing yourself falling ill recurrently after performing oral sex on your wife, you both should get tested for STDs. Also, if you have a recurrent cough, with phlegm and breathlessness, you should get tested for tuberculosis.
Although tuberculosis spreading through oral sex is rare, it is best to get tested and prevent its spread. Want some relief from cough and sore throat? Here are some natural ways you can find some relief. Image source: Shutterstock For more articles on Sex, visit our sex guide section. For daily free health tips, sign up for our newsletter,
What to do if your girlfriend has the flu?
Pneumonia – Pneumonia is an infection in one or both lungs and a serious flu complication. Worsening flu symptoms can indicate that the person has pneumonia, Check for the following:
a fevera cough with pus or blood-tinged sputuma bluish tint to the lips or facedifficulty breathingchest pain
Anyone who experiences any of these symptoms requires immediate medical attention. Antibiotics and hospitalization may be necessary. When a person with the flu coughs, sneezes, or talks, they release infectious droplets into the air. A person can catch the flu if they are close enough to breathe in these droplets — within about 6 feet of the person who is ill.
Keep the person with the flu in a separate room, if possible. Wear a face mask when providing care.Limit the time spent with the person or keep a chair outside their room for chatting. Wash the hands frequently with soap and water, and dry them with a fresh paper towel each time. Use an alcohol-based hand sanitizer if soap and water are not available.Use sanitizing wipes or sprays on surfaces that could be contaminated, such as bathroom handles, sinks, and doorknobs.Do not share linens, towels, washcloths, utensils, or glasses.Ensure that the ill person wears a mask when using a shared bathroom or coming into close contact with others.
The CDC recommend that everyone aged 6 months and older receive flu vaccination. For most people with the flu, symptoms resolve within 5–7 days without professional medical care. However, a person should see a doctor if symptoms do not improve after several days of rest and home care. Also, seek medical attention if any of the following develop:
difficulty breathing, such as shortness of breathpain or pressure in the chest or abdomensudden dizziness or feeling about to faintsigns of dehydrationa persistent high fever that over-the-counter medication does not improvea sudden worsening of symptoms after they had begun to improve
Anyone providing care who has worries or concerns should ask a medical professional for advice. Caring for someone with the flu involves helping to ease symptoms and being watchful for signs of complications. Most people recover from the flu within a week or two, while others have a higher risk of complications such as pneumonia.

How Long Are You Contagious With The Flu? It’s shaping up to be one of the worst flu seasons in years. If you are one of the thousands of Americans who are sick with the flu, this one’s for you. You’ve spent the past couple of days cooped up in your house watching bad TV, fighting the fever sweats and expelling a baffling amount of mucus.
- As you start to resemble a human being again, you might feel pressure to head back to work.
- But when is it really OK to return? Many people go back as soon as their symptoms start to resolve, which could be putting your co-workers at risk.
- Those unpleasant symptoms are actually the result of your immune response battling the flu virus.
Take fever for example. Your body starts a fever because the flu virus as well at high temperatures, and some immune cells actually, All that gooey mucus you’ve been coughing up is good at trapping viruses before they can infect other cells.Your body is in an all out war, you against the virus.
- Immune cells seek out and destroy virus-infected cells.
- As your airways get irritated, you cough and sneeze.
- And that’s exactly what the flu wants.
- That’s because the flu is spread from person to person in virus-containing droplets that are produced when a sick person coughs, sneezes or even,
- When you cough, tiny droplets that fly from your mouth can travel as far as at speeds ranging from 25-50 mph.
Sometimes they can stay suspended for hours. If someone inhales those particles, they can become infected. The flu can even be transmitted if someone touches a surface contaminated with flu and then touches her face or mouth. That’s why hand-washing is so important when you’re sick.
- But the best way to prevent spreading the flu is to stay home if you can.
- So how long are you really contagious with the flu? The CDC says you are contagious one day before you start feeling sick and up to seven days after.
- If you’re a kid, elderly, or have a weak immune system, you can be contagious for even longer.
