Additional questions and answers on about the H1N1 flu
What are the signs and symptoms of H1N1 flu in people?
The symptoms of H1N1 flu in people are similar to the symptoms of regular human flu and include:
- fever
- cough
- sore throat
- body aches
- headache
- chills
- fatigue
Some people have reported diarrhea and vomiting associated with H1N1 flu. In the past, severe illness (pneumonia and respiratory failure) and deaths have been reported with H1N1 flu infection in people. Like seasonal flu, H1N1 flu may cause a worsening of underlying chronic medical conditions.
How does H1N1 flu spread?
Spread of this H1N1 influenza A (H1N1) virus is thought to be happening in the same way that seasonal flu spreads. Flu viruses are spread mainly from person to person through coughing or sneezing of people with influenza. Sometimes people may become infected by touching something with flu viruses on it and then touching their mouth or nose.
How can someone with the flu infect someone else?
Infected people may be able to infect others beginning 1 day before symptoms develop and up to 7 or more days after becoming sick. That means that you may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick.
What should I do to keep from getting the flu?
First and most important: wash your hands. Try to stay in good general health. Get plenty of sleep, be physically active, manage your stress, drink plenty of fluids, and eat nutritious food. Try not touch surfaces that may be contaminated with the flu virus. Avoid close contact with people who are sick.
Are there medicines to treat H1N1 flu?
Yes. CDC recommends the use of oseltamivir or zanamivir for the treatment and/or prevention of infection with these H1N1 influenza viruses. Antiviral drugs are prescription medicines (pills, liquid or an inhaler) that fight against the flu by keeping flu viruses from reproducing in your body. If you get sick, antiviral drugs can make your illness milder and make you feel better faster. They may also prevent serious flu complications. For treatment, antiviral drugs work best if started soon after getting sick (within 2 days of symptoms).
How long can an infected person spread H1N1 flu to others?
People with H1N1 influenza virus infection should be considered potentially contagious as long as they are symptomatic and possible for up to 7 days following illness onset. Children, especially younger children, might potentially be contagious for longer periods.
What surfaces are most likely to be sources of contamination?
Germs can be spread when a person touches something that is contaminated with germs and then touches his or her eyes, nose, or mouth. Droplets from a cough or sneeze of an infected person move through the air. Germs can be spread when a person touches respiratory droplets from another person on a surface like a desk and then touches their own eyes, mouth or nose before washing their hands.
How long can viruses live outside the body?
We know that some viruses and bacteria can live 2 hours or longer on surfaces like tables, doorknobs, and desks. Frequent hand washing will help you reduce the chance of getting contamination from these common surfaces.
What can I do to protect myself from getting sick?
There is no vaccine available right now to protect against H1N1 flu. Everyday precautions as outlined above can help prevent the spread of germs that cause respiratory illnesses like influenza.
What is the best technique for washing my hands to avoid getting the flu?
Washing your hands often will help protect you from germs. Wash with soap and water. or clean with alcohol-based hand cleaner. we recommend that when you wash your hands — with soap and warm water — that you wash for 15 to 20 seconds.
When soap and water are not available, alcohol-based disposable hand wipes or gel sanitizers may be used. If using gel, rub your hands until the gel is dry. The gel doesn't need water to work; the alcohol in it kills the germs on your hands.
What should I do if I get sick?
If you live in areas where H1N1 influenza cases have been identified and become ill with influenza-like symptoms, including fever, body aches, runny nose, sore throat, nausea, or vomiting or diarrhea, you may want to contact your health care provider, particularly if you are worried about your symptoms. Your health care provider will determine whether influenza testing or treatment is needed.
If you are sick, you should stay home and avoid contact with other people as much as possible to keep from spreading your illness to others.
If you become ill and experience any of the following warning signs, seek emergency medical care.
In children emergency warning signs that need urgent medical attention include:
- Fast breathing or trouble breathing
- Bluish skin color
- Not drinking enough fluids
- Not waking up or not interacting
- Being so irritable that the child does not want to be held
- Flu-like symptoms improve but then return with fever and worse cough
- Fever with a rash
In adults, emergency warning signs that need urgent medical attention include:
- Difficulty breathing or shortness of breath
- Pain or pressure in the chest or abdomen
- Sudden dizziness
- Confusion
- Severe or persistent vomiting
Can I get H1N1 influenza from eating or preparing pork?
No. H1N1 influenza viruses are not spread by food. You cannot get H1N1 influenza from eating pork or pork products. Eating properly handled and cooked pork products is safe.
