Medical Terms Defined

Avian flu (AI) is caused by influenza viruses that occur naturally among wild birds. Low pathogenic AI is common in birds and causes few problems. Highly pathogenic H5N1 is deadly to domestic fowl, can be transmitted from birds to humans, and is deadly to humans. There is virtually no human immunity and human vaccine availability is very limited. SARS is a respiratory disease in humans which is caused by the SARS coronavirus (SARS-CoV).There has been one near pandemic to date, between November 2002 and July 2003, with 8,096 known infected cases and 774 deaths.

Pandemic flu is virulent human flu that causes a global outbreak, or pandemic, of serious illness. Because there is little natural immunity, the disease can spread easily from person to person. Currently, there is no pandemic flu. Seasonal (or common) flu is a respiratory illness that can be transmitted person to person. Most people have some immunity, and a vaccine is available.

About Influenza A(H1N1)

Influenza A (H1N1) was initially called ‘swine flu’ as it was found to be similar to influenza viruses that affect pigs. Scientists later found that the virus was an assortment of genes which were of avian, human and swine origin and quite different from what they believed it to be.

In June 2009, the WHO declared Influenza A (H1N1) a global pandemic. This new strain now exists in many communities all over the world.

As this is a new strain of virus, most people will not have resistance, and it can potentially spread quickly and infect a large proportion of the population in a short period of time.

While the drugs Tamiflu® and Relenza® can be used to treat a H1N1 infection, there is currently no vaccine available.

Causes

Human-to-human transmission of Influenza A (H1N1) has been occurring all over the world. Flu can be spread when a person coughs, sneezes or speaks. The flu viruses are transmitted into the air through droplets that can be inhaled by many other people. When these viruses enter the nose, throat or lungs of an infected person, they begin to multiply, causing symptoms of flu.

Influenza A (H1N1) infection is highly contagious. People with an infection may be able to spread the flu virus a day before the symptoms appear and throughout the period that he/she is ill.

Symptoms of Influenza A(H1N1)

Just like the seasonal flu, Influenza A (H1N1) infection in humans can vary in severity from mild to severe. Signs and symptoms of infection may include the following:

• High fever (Temperature > 38°C)
• Cough
• Muscle pains
• Sore throat
• Fatigue or tiredness
• Headache
• Nausea
• Vomiting or diarrhea

See your family doctor if you have any of the above symptoms.

Most cases of Influenza A (H1N1) are mild and self-limiting and patients recover. However, there are several groups of individuals are at high-risk of developing complications from this strain. These high-risk groups include:

• Persons aged 65 years and older
• Children under five years of age
• Those with chronic metabolic disease (including diabetes mellitus), chronic pulmonary or heart disease
• Those with medical conditions such as cancer on active treatment, on organ transplant dialysis, or immunosuppression (including immunosuppression caused by medications or by HIV)
• Children and teenagers less than 18 years who are receiving long-term aspirin therapy
• Pregnant women

If you are pregnant, undergoing cancer treatment or dialysis you should consult your primary care specialist. All other groups should go to a Pandemic Preparedness Clinic (PPC), polyclinic or their primary care doctor.

Call 995 if you experience the following warning signs or if your symptoms worsen:

• Difficulty in breathing or chest pain
• Purple or blue discolouration of the lips
• Severe and persistent vomiting
• Deterioration of symptoms since the onset of illness
• Flu-like symptoms improve but then return with fever and worse cough
• Signs of dehydration such as dizziness when standing, the absence of urination of lack of tears when children cry
• Fits
• Loss of appetite
• Less responsive than normal, drowsy or becomes more confused

Treatment of Influenza A(H1N1)

Anti-Viral Drugs
There are anti-viral medications available to treat people who are infected. Anti-viral medications such as Tamiflu® or Relenza® fight against the influenza viruses from reproducing in the body.

These medications, when taken early in the course of infection (within 2 days of the appearance of symptoms) may:

• Reduce the severity of the infection with faster recovery from the illness.
• Prevent serious flu complications.

In most cases, laboratory testing to confirm infection with Influenza A (H1N1) is not needed before starting treatment. Doctors will exercise clinical judgement in prescribing anti-viral drugs on a case-by-case basis taking into account of patient’s risk of developing influenza-related complications, prevalence of infection in the community and the risks and benefits of treatment. As with any other medications, there are potential side-effects related to the use of Tamiflu.

Vaccinations
The current seasonal flu vaccine gives little (if any) protection against the new Influenza A (H1N1) strain. There is no vaccine available for this new strain of H1N1 virus yet. Vaccine manufacturers are currently in the process of producing and testing a vaccine for this new strain.

Flu Pandemics

1918: The Spanish flu pandemic remains the most devastating outbreak of modern times. Caused by a form of the H1N1 strain of flu, it is estimated that up to 40% of the world's population were infected, and more than 50 million people died, with young adults particularly badly affected.

1957: Asian flu killed two million people. Caused by a human form of the virus, H2N2, combining with a mutated strain found in wild ducks. The impact of the pandemic was minimised by rapid action by health authorities, who identified the virus, and made vaccine available speedily. The elderly were particularly vulnerable.

1968: An outbreak first detected in Hong Kong, and caused by a strain known as H3N2, killed up to one million people globally, with those over 65 most likely to die.

Prevention

Since the illness occurs through direct contact with infectious material and respiratory secretions, it is important to practice good personal hygiene. Take these everyday steps to protect your health:

Cover Your Nose and Mouth

• With a tissue when you cough or sneeze and dispose the tissue properly in the trash after use.

Wash Your Hands

• Regularly and thoroughly with soap and water
• Before and after preparing food
• After going to the toilet
• Before and after eating
• After blowing your nose
• After using your hand when coughing or sneezing

Contain the Spread of Flu

• Use a serving spoon when sharing food from a common dish.
• Do not share personal items such as toothbrushes and towels.
• Avoid touching your eyes, nose or mouth.
• Consider wearing a mask and avoid crowded places if you are in a high-risk group.
• Stay at home and do not go to work or school if ill.
• Head to your nearest Pandemic Preparedness Clinic (PPC) if you have flu like symptoms.

Build Up Your Immunity

• If you are a smoker, quit smoking. It harms you and your family.
• Take more fruit and vegetables. Fruit and vegetables are the most power-packed combination of nutrients your body needs for good health.
• Drink the equivalent of 8 glasses of fluid daily.
• Engage in 30 minutes of moderate intensity physical activity on 5 or more days a week.
• Learn to relax and rest.

Keep Your Environment Clean

• Do not throw leftover food on the floor or in the open.
• Do not leave food in common areas for stray animals.
• Do not spit on the floor and common areas.
• Throw used masks, tissue or litter into rubbish bins.

If you are living with someone who is infected

• Observe good personal hygiene.
• Do not have meals together with the ill person as masks have to be removed during meals.
• Wear a surgical mask and remain at a distance of at least 2 metres from one another if you need to communicate with the ill person.
• Maintain good ventilation at home (e.g. keeping windows open in toilets, kitchens and rooms)
• Be socially responsible by limiting contact with someone outside your household. When you need to go out, consider wearing a mask and avoid crowded places.

If you are looking after someone who is infected

• Wear a surgical mask.
• Clean your hands with soap and water (or an alcohol-based hand rub) after you have touched the infected person, soiled linens or laundry.
• Be alert and call for help when the infected person’s symptoms deteriorate of if the symptoms worsen.
• If you are pregnant you should not be looking after someone who is infected as you are at increased risk of flu-related complications.
