FAQs H1N1 Influenza
Q. What is the (H1N1) Influenza virus?
A. - The H1N1 Influenza virus can cause acute infection in the respiratory tract. It was the influenza virus that caused the Pandemic Influenza Outbreak in 2009 but after that the H1N1 virus causes Seasonal Influenza
Q. How do people become infected with the virus?
A. - The H1N1 virus is spread from person to person.
- It can be passed to other people by exposure to infected droplets expelled by coughing or sneezing that can be inhaled, or that can contaminate hands or surfaces.
- The time from infection to illness known as the incubation period is about 2 days
- To prevent spread, people who are ill should cover their mouth and nose when coughing or sneezing, stay home when they are unwell, clean their hands regularly, and keep some distance from other people, as much as possible.
Q. What are the signs and symptoms of typical infection?
A. - Signs of the H1N1 influenza includes general body weakness, fever, cough, headache, muscle and joint pain, sore throat and runny nose, and sometimes vomiting and diarrhoea.
- The majority of people with H1N1 influenza experience mild illness and recover fully without treatment.
Q. When should someone seek medical care?
A. - People should seek medical care if they experience shortness of breath or difficulty breathing, or if a fever, and especially high fever, continues more than three days. For parents with a young child who is ill, seek medical care if a child has fast or labored breathing, continuing fever or convulsions (seizures).
- Supportive care at home - resting, drinking plenty of fluids and using a pain reliever for aches and pains - is adequate for recovery in most cases. A non-aspirin pain reliever should be used for children or adolescents under age 18.
Q. What about Vaccines for H1N1 Influenza?
A. -The most effective way to prevent the disease is vaccination. Safe and effective vaccines are available and have been used for more than 60 years. Among healthy adults, influenza vaccine provides protection, even when circulating viruses may not exactly match the vaccine viruses.
- WHO recommends annual vaccination for pregnant women at any stage of pregnancy, children aged between 6 months to 5 years, elderly individuals (aged more than 65 years), individuals with chronic medical conditions, health-care workers.
Q. Are the vaccines safe for pregnant women?
A. - To date, studies do not show harmful effects from the H1N1 influenza vaccine with respect to pregnancy, fertility, or a developing embryo or fetus, birthing or post-natal development
Q. What about my child's safety from a reaction?
A. The most frequent vaccine reactions in children following influenza immunization are similar to those seen after other childhood immunizations (such as soreness at the injection site, or fever). A child's health care provider or vaccinator can advise on the most appropriate methods for relief of the symptoms. - If there are concerns about a child's safety from a reaction, consult a health care provider as soon as possible. Please note that a child may suffer from a condition not related to immunization, which coincidentally developed after vaccination.
Q. How can I protect myself and family from H1N1 Influenza ?
A. You can prevent getting infected by taking the following measures:
keeping your distance from people who show symptoms of influenza-like illness, such as coughing and sneezing (trying to maintain a distance of about 1 metre if possible);
- clean hands thoroughly with soap and water, or cleanse them with an alcohol-based hand rub on a regular basis (especially if touching surfaces that are potentially contaminated);
- avoid touching your mouth, nose and eyes as much as possible;
reduce the time spent in crowded settings if possible;
- improve airflow in your living space by opening windows;
- practise good health habits (including adequate sleep, eating nutritious food, and keeping physically active); and
- getting yourself (or family members age 6 months and older) vaccinated against H1N1 influenza, if possible.
Q. How do I know if I have H1N1 Influenza?
A. Typical symptoms to watch for include fever, cough, headache, body aches, sore throat and runny nose.
Q. What should I do if I think I have H1N1 Influenza?
A. - If you feel unwell, have a fever, cough or sore throat:
- stay at home and keep away from work, school or crowds;
- rest and take plenty of fluids;
- cover your coughs and sneezes. If using tissues, make sure you dispose of them carefully. Clean your hands immediately after with soap and water or cleanse them with an alcohol-based hand rub;
- if you do not have a tissue close by when you cough or sneeze, cover your mouth as much as possible with the crook of your elbow;
Q. Should I take an antiviral drug now just in case I catch the H1N1 virus?
A. - In general, WHO does not recommend the use of antiviral drugs for prevention of H1N1 Influenza. Antiviral drugs should be taken if your health care provider advises you to do so.
- These drugs are generally available by prescription.
- Caution should be exercised when buying antiviral drugs over the Internet.
Q. What about breastfeeding? Should I stop if I am ill?
A. - No, not unless your health care provider advises it. Studies on influenza infections show that breastfeeding is most likely protective for babies - it passes on helpful maternal immunities and lowers the risk of respiratory disease.
- Breastfeeding provides the best overall nutrition for babies and increases their defense factors to fight illness.
Q. Can I travel?
A. - If you are feeling unwell or have symptoms of influenza, you should delay travel. If you have any doubts about your health, you should check with your health care provider.
Q. Who is more at risk of severe illness from H1N1 Influenza?
A. - Some groups of people appear to be at higher risk of more complicated or severe illness, including:
- pregnant women;
- infants, and young children particularly under age 2;
- people of any age with certain chronic health conditions (including asthma or lung disease, heart disease, diabetes, kidney disease or some neurological conditions);
- people with severely compromised immune systems.
Q. Are there special recommendations for pregnant women or other higher risk groups?
A. - WHO recommends that pregnant women, or others at higher risk of severe illness and their caregivers, be vaccinated against H1N1 influenza and take all the necessary precautions, including hygiene measures, to prevent the spread of illness.
Q. What about risk of death?
A. - The majority of people with H1N1 influenza experience mild illness and the overall risk of dying from this infection is low.
Q. Is it safe to eat pork and pork products?
A. - Yes. The H1N1 Influenza virus has not been shown to be transmissible to people through eating properly handled and prepared pork (pig meat) or other products derived from pigs.
Q. What is the Treatment for H1N1 Flu?
A. - Antiviral drugs for influenza are available and may reduce severe complications and deaths. Ideally they need to be administered early (within 48 hours of onset of symptoms) in the disease.
