What is the Flu?
Influenza: A Highly Contagious Respiratory Illness
Influenza, or the flu, is a contagious illness caused by viruses3. It can have mild to severe symptoms and can be deadly in some cases. Knowing about the flu helps us prevent and manage it.
The flu is a viral infection that mainly hits the nose, throat, and lungs4. It usually happens during the winter in the U.S3.. There are many strains of the virus, but types A and B are the most common ones.
This disease spreads easily through droplets from coughing, sneezing, or talking3. It can also spread by touching surfaces or objects that have the virus on them. So, good hygiene and preventive steps are key to avoiding it.
Even though the flu is often mild, it can be serious for some people3. Serious problems like pneumonia or even death can happen. It’s important to know about the flu and how to prevent it to stay healthy and protect others.
“The flu is a highly contagious respiratory illness caused by influenza viruses, which can lead to severe complications and even death in some cases.”
To sum up, the flu is a contagious illness caused by viruses345. It can be mild or severe. Understanding it helps us prevent and manage it.
How the Flu Spreads
The flu spreads mainly through droplets when someone coughs, sneezes, or talks6. These droplets can land on people nearby or be breathed in6. It can also spread by touching something with the virus and then touching your face6.
The flu can spread until symptoms go away6. It can live on surfaces for up to 48 hours6. Flu germs can spread up to 3 feet away through coughs and sneezes6. The virus is most likely to spread in the first 3 to 4 days after getting the flu6.
Getting a flu vaccine can lower the risk of catching the flu by 40%-60%6. Vaccines help prevent millions from getting the flu each year6. They also make the flu less severe for those who do get sick6. Vaccines prevent around 100,000 flu-related hospitalizations each year6.
Flu vaccines are crucial for kids aged 6 months to 17 years6. They also protect newborns whose mothers got the vaccine6. The vaccine’s effectiveness depends on your health and age6.
People are most contagious during the first 3 days of being sick7. Most people get better in about a week, but cough and fatigue can linger7. To stop spreading the flu, stay home until you’re fully recovered and your fever is gone for 24 hours7.
The flu spreads mainly by coughing, sneezing, or close contact7. Symptoms start suddenly, 1-4 days after getting the virus7. You can be contagious from 1 day before symptoms start to 5-7 days after falling ill7. Some people can still spread the virus even after 5-7 days7.
Antiviral drugs work best if taken right after getting sick7. Over-the-counter drugs like acetaminophen or ibuprofen help with symptoms7. The flu shot is the best way to prevent the flu, recommended for people 6 months and older7. New flu vaccines come out every year to fight new flu viruses7.
Getting the vaccine at the right time, before flu season, works best7. Flu season changes with the weather and location7. Traveling with others can increase your chance of getting the flu7. Health groups track flu outbreaks during the season7.
About 5% to 20% of people in the U.S. get the flu each year8. Between 3,000 and 49,000 Americans die from the flu and its complications yearly8. Avian influenza (H5N1) spreads to humans by touching infected birds8. Everyone 6 months and older should get a flu vaccine every year8.
Influenza types A and B are the most serious flu viruses8. Influenza Type C viruses cause mild illness and are less common8.
Flu Symptoms
The flu, or influenza, is a highly contagious illness that can cause many unpleasant symptoms9. Most people get the flu from the influenza type A virus. This virus can cause big outbreaks and serious illness during the winter9.
Common symptoms of the flu include fever, cough, sore throat, and runny nose10. Young children and people over 65 often get the flu more seriously10. Some may also have vomiting and diarrhea, especially kids9. Not everyone with the flu will have a fever.
Influenza A infection symptoms include fever, chills, muscle pains, coughing, sore throat, sneezing, and runny nose9. In children, it can cause abdominal pain, nausea, and vomiting9. This infection can lead to serious complications like pneumonia, breathing problems, and even death9.
Most people with the flu have a mild case and don’t need to see a doctor11. With rest and self-care, healthy people usually get better in a week10. But, some groups like young kids, older adults, and those with health issues are at higher risk of serious flu complications1011.
“Influenza A infection is more serious than the common cold and can cause major outbreaks and severe disease.”9
High-Risk Groups for Complications
Some groups face a higher risk of serious flu complications12. This includes young kids, especially those under 6 months, and older adults over 65. Pregnant women and those with conditions like asthma, diabetes, or heart disease are also at risk12. People from certain racial and ethnic groups, like non-Hispanic Black, Hispanic or Latino, and American Indian or Alaska Native, are more likely to be hospitalized with the flu12.
People at Higher Risk of Flu Complications
- Young children, especially infants under 6 months old, who have the highest hospitalization and death rates from the flu12
- Adults aged 65 and older, who have a higher risk of developing severe influenza symptoms13
- Pregnant individuals and those up to 2 weeks after pregnancy, who are at a higher risk of severe flu symptoms13
- People with certain medical conditions, such as asthma, diabetes, or heart disease, who are at high risk for influenza-related complications12
- Individuals with a body mass index (BMI) of 40 or higher, who are at an increased risk of flu-related complications12
- Individuals living in nursing homes or long-term care facilities, who are at a heightened risk for flu complications12
- People with weakened immune systems due to diseases like HIV/AIDS or certain cancers, who are at an increased risk of flu complications12
High-risk groups need to take extra steps to prevent the flu and get medical help right away if they feel sick12. Getting treatment and taking preventive steps can lower the risk of serious flu complications13.
Preventing the Flu
Getting an annual flu vaccine is the best way to protect against the flu14. These vaccines protect against the most common flu viruses14. They help your body make antibodies to fight off the flu15. It takes about two weeks for your body to get ready after the shot15.
Other steps can also help stop the flu from spreading14. Keep a distance from others, cover your mouth when you cough, and wash your hands often14. Using hand sanitizers and wearing masks can also help14.
Clean surfaces like doorknobs and phones often to get rid of germs14. Good hygiene, like getting enough sleep and eating well, also boosts your immune system14.
Workplaces and schools should have plans for flu outbreaks14. They should offer flu shots and have tissues and hand cleaners ready14. By doing this, we can all help fight the flu together14.
“The single best way to reduce the risk of seasonal flu and its complications is to get vaccinated each year.”14
Flu Prevention Method | Effectiveness |
---|---|
Annual Flu Vaccination | Highly Effective14 |
Frequent Handwashing | Effective14 |
Physical Distancing | Moderately Effective14 |
Covering Coughs and Sneezes | Effective14 |
Wearing a Mask | Effective14 |
Cleaning Frequently Touched Surfaces | Effective14 |
Using the flu vaccine and other steps can really lower your risk of getting the flu14. These actions protect you and those around you during flu season141615.
Diagnosing the Flu
Healthcare professionals use physical exams, symptom recognition, and various tests to spot the flu. These tests are key in confirming the flu and guiding treatment.
Flu Testing Options
Rapid tests can give results in about 10-15 minutes17. Molecular tests, which look for the flu virus’s genetic material, are more precise and take 15-20 minutes17. For a deeper look, tests like RT-PCR, viral culture, and immunofluorescence take longer but are thorough17.
Some rapid tests work better in kids than in adults17. But, some tests might miss the flu, showing false negatives17.
It’s possible to have both the flu and COVID-19 at the same time17. A new test can find both flu viruses and SARS-CoV-2, helping track both illnesses17. This test has been approved for use in labs to monitor health trends17.
Tests can diagnose the flu in under 30 minutes18. The Liat assay can tell if it’s flu A or B in 20 minutes18. The FilmArray system finds viruses, including flu, in an hour18. The Xpert Flu A/B test quickly tells if it’s flu A or B18. The QuickVue Test can also spot flu A and B from nasal samples18.
Scientists are creating a paper-strip test for quick, cheap flu diagnosis in remote areas18. The NIAID backs research for faster, more precise, and affordable flu tests18. This is vital because different flu strains react differently to medicines18. Quick test results help doctors give the best care for flu patients18.
Healthcare has many flu testing options, from quick tests to detailed ones, to accurately diagnose the flu and guide treatment. Since the flu and COVID-19 can happen together, testing for both might be needed in some cases171819.
Flu Treatment
Treating the flu often means resting, drinking plenty of fluids, and sometimes taking antiviral drugs. Most people can get better at home without needing prescription drugs20. But, those with severe cases or high risk of complications might need antiviral drugs to lessen symptoms and illness length20.
Common antiviral drugs for the flu include oseltamivir (Tamiflu), baloxavir (Xofluza), and zanamivir (Relenza). These drugs are most effective when started within the first 48 hours of getting sick20. They can cut down on illness time and lower the chance of serious problems like pneumonia20.
Remember, antibiotics don’t work against the flu because it’s a virus, not bacteria20. Wrong use of antibiotics can cause infections that don’t respond to treatment20. Doctors might suggest antiviral drugs or supportive care based on your symptoms and risk factors.
To stop the flu from spreading, the CDC says to wear a mask and stay home until your fever is gone for at least 24 hours without using fever reducers20. Good hand hygiene and covering your mouth when you cough or sneeze can also help stop the virus from spreading21.
Flu Antiviral Medications | How They Work | Recommended Usage |
---|---|---|
Oseltamivir (Tamiflu) | Inhibits the influenza virus from replicating and spreading within the body | Taken within 48 hours of symptom onset, can shorten illness duration by about 24 hours22 |
Baloxavir (Xofluza) | Disrupts the influenza virus’s ability to replicate | Taken within 48 hours of symptom onset, can reduce illness duration and severity20 |
Zanamivir (Relenza) | Interferes with the influenza virus’s ability to spread within the respiratory tract | Administered via inhalation, typically within 48 hours of symptom onset20 |
Flu antiviral drugs can help, but the flu usually lasts 7-14 days for most people22. The cough might last a bit longer. It’s key to rest, drink plenty of water, and see a doctor if your symptoms get worse or your fever doesn’t go away.
“Antiviral medications can be a valuable tool in managing the flu, but they work best when taken early in the illness. It’s important to consult with a healthcare provider to determine if antiviral treatment is appropriate for your situation.”
Caring for Someone with the Flu
Setting Up a Separate Sick Room
When a family member gets the flu, it’s key to make a special sick room. This stops the virus from spreading to others23. The flu spreads through the air, so keeping the sick person in their own space helps a lot24.
Make sure the sick room has things like tissues, hand sanitizer, and a humidifier. These items help with symptoms25. Caregivers should keep their distance and follow good hygiene to avoid getting sick24.
The sick person should stay in their room until their fever is gone for a day without medicine23. This step is important to stop the flu from spreading. It lets the sick person get better safely, keeping others safe too.
Taking care of someone with the flu is tough, but with the right steps and a well-prepared sick room, caregivers can help. They support the sick person’s recovery and keep everyone else safe24.
Flu Caregiver Essentials | Importance |
---|---|
Tissues | To catch coughs and sneezes and prevent the spread of respiratory droplets. |
Hand sanitizer | To maintain proper hand hygiene and reduce the risk of transmission. |
Humidifier | To ease breathing and alleviate respiratory symptoms. |
Cleaning supplies | To disinfect the sick room and high-touch surfaces regularly. |
Creating a sick room and following good care steps helps both the sick person and the caregivers. It ensures everyone stays safe and healthy242523.
Cleaning and Disinfecting
Keeping your space clean and germ-free is key during flu season. The flu virus can live on surfaces for up to 48 hours. So, regular cleaning and disinfecting are a must26. You don’t need to close schools or do deep cleans to stop the flu. Standard cleaning and disinfecting work well to remove or kill the virus26.
Focus on cleaning high-touch areas like desks, counters, doorknobs, and keyboards26. Use disinfecting wipes on electronics often touched, following the label’s directions26. Also, handle waste properly with no-touch baskets and wash hands after touching it26.
Use cleaning products and disinfectants as the EPA label says, especially for fighting the flu A virus26. Studies show the flu virus can last on surfaces for 2 to 8 hours. Regular cleaning and disinfecting can remove or kill it27. Make sure to rinse surfaces first before applying disinfectant for best results27.
To disinfect, mix 1 tablespoon of bleach with 1 quart of water or ¼ cup of bleach with 1 gallon of water27. Always follow the safety warnings on product labels carefully. Mixing some products can be dangerous2627.,
Don’t forget to clean upholstered furniture, hard-to-clean fabrics, and high-touch areas in vehicles like steering wheels and door handles28. By following these guidelines, you can make your space safer during flu season262728.,,
“Proper disinfection is key to preventing the spread of the flu virus during the winter months. Regularly cleaning high-touch surfaces and following label instructions for cleaning products can make a significant difference in keeping your family and community healthy.”
The flu is a highly contagious illness. Cleaning and disinfecting your spaces can protect you and others from getting it262728.
Flu and Dehydration
Preventing Fluid Loss
The flu can make you very sick, often leading to dehydration from fever, vomiting, and diarrhea29. It’s key to drink enough fluids to stop dehydration and avoid its serious problems30.
Drinking water, juice, and warm soups is vital when you have the flu30. Those taking care of someone sick should watch how much fluid they drink and use to make sure they’re hydrated31. Kids, older people, and babies are more likely to get dehydrated from the flu. If they show signs like extreme thirst, dark urine, or sunken eyes, they need a doctor fast31.
Stopping fluid loss is key to beating the flu and avoiding bad outcomes. By drinking enough water and keeping an eye on fluid levels, people can get through this illness better31.
Dehydration Risk Factors | Symptoms of Dehydration |
---|---|
|
|
Dehydration is the most common issue after viral gastroenteritis, like the flu, showing why quick medical help is needed for severe symptoms29. Keeping up with fluid intake and watching for dehydration signs helps manage the flu and prevents serious issues31.
“Water makes up about 60% of the human body, and dehydration leads to the loss of electrolytes such as potassium and sodium.”30
Staying hydrated is key to getting better from the flu and avoiding problems. Knowing how important fluids are and spotting dehydration signs helps people take good care of themselves during the flu.
Managing Flu Symptoms
Dealing with flu symptoms can be tough, but there are ways to ease the discomfort and help you get better. Taking over-the-counter pain relievers like acetaminophen or ibuprofen can help reduce fever and ease pain32. Also, getting enough rest and drinking plenty of water can make you feel better32. Remember, kids and teens should not take aspirin because it can cause Reye’s syndrome32.
Some medications can also offer relief. The CDC suggests using baloxavir marboxil (Xofluza), oseltamivir (Tamiflu), peramivir (Rapivab), or zanamivir (Relenza) within 48 hours of getting sick32. These drugs can make the flu shorter and less severe33.
It’s important to watch out for those at high risk, like people over 65, kids under 2, those with ongoing health issues, and Native American and Alaska Native folks32. They might need extra care and should see a doctor if their fever goes over 102°F32.
Knowing how to handle flu symptoms can help you feel better faster. Taking action early and getting medical advice when needed can make recovery smoother and more comfortable.
“The flu can be a formidable foe, but by managing symptoms proactively, we can emerge stronger and healthier on the other side.”
Emergency Warning Signs
When dealing with the flu, some signs mean you need urgent medical help34. These include trouble breathing, ongoing vomiting, confusion, and symptoms that get better but then come back with more fever and cough34. Kids and older people should get medical help right away if they show these signs3.
The flu can be serious, especially for those at higher risk3. This includes people with ongoing health issues like asthma, heart disease, or diabetes, as well as those over 653. Pregnant women and those with a BMI of 40 or higher are also at greater risk3.
Flu symptoms usually clear up in a week or two34. But, you should get medical help if you see any emergency signs:
- Difficulty breathing or shortness of breath
- Persistent pain or pressure in the chest or abdomen
- Sudden dizziness or confusion
- Severe or persistent vomiting
- Bluish lips or face
Don’t wait if you or someone close to you shows these signs. Get medical care right away35. Quick action can help manage the flu and prevent serious problems34.
“The flu can be a serious illness, especially for certain high-risk groups. It’s crucial to be aware of the emergency warning signs and seek prompt medical attention if they occur.”
Flu Emergency Signs | Potential Complications |

If you or someone you know has these emergency signs, don’t delay. Get medical help right away3. Quick treatment can help avoid serious issues and aid in a quick recovery34353.
Flu and COVID-19
As we deal with the COVID-19 pandemic, it’s key to know how the flu and this new virus are linked. They are caused by different viruses but can both infect you at once36. Symptoms like cough, runny nose, sore throat, and fever are common to both36.
It’s rare to test positive for both the flu and COVID-19 at once37. But knowing this is possible is important. Both illnesses can be serious, especially for those at high risk36.
If you start feeling sick, talk to your doctor37. They might suggest tests for both flu and COVID-19. COVID-19 can cause loss of taste and smell in 38% to 55% of cases37. Shortness of breath can also happen, and it might be worse and last longer than with the flu37.
About 1% to 2% of COVID-19 cases are in kids worldwide37. A rare condition called MIS-C is linked to COVID-19 in kids, affecting those from toddlers to teens37.
Preventing the spread of these illnesses is key. Vaccines, masks, good hygiene, and staying home when sick help protect us from the flu and COVID-1936. By doing these things, we can keep ourselves and others safe36.
Statistic | Flu | COVID-19 |
---|---|---|
Estimated Illnesses in the U.S. (2019) | 35 million37 | Over 95 million38 |
Deaths in the U.S. (2021-2022 season) | 5,000 – 14,00038 | Over 1 million38 |
The numbers show how big an impact the flu and COVID-19 have. It’s vital to take steps to prevent these illnesses and get medical help when needed. By working together, we can keep ourselves, our families, and our communities safe36.
“Getting both COVID-19 and influenza vaccines is necessary for comprehensive protection against both illnesses.”36
Conclusion
The flu is a contagious illness that affects many people. It can hit communities and public health hard. By knowing how to spot symptoms, prevent it, and treat it, we can protect ourselves and our loved ones39. Last year, over 5,000 people were hospitalized with the flu in the U.S., and about 5,000 died from it40. People with health issues are more likely to get very sick from the flu.
Stopping the flu before it spreads is key. This means getting a flu shot every year and washing your hands often39. The vaccines for the 2021-2022 season covered many types of flu viruses. No one vaccine was better than another. Getting quick medical help, especially for those at high risk, can help fight the flu and stop more problems.
41 The 1918-1919 flu pandemic shows us why we must always be ready for new flu threats. By staying updated, taking steps to prevent it, and getting the right care, we help everyone. This way, we keep our health safe and our communities healthy.
