PANDEMIC FLU: Influenza A (H1N1) Virus

INTRODUCTION
What is the new influenza A (H1N1) virus that has been causing recent outbreaks globally?
The recent outbreaks of disease in people globally are caused by a new influenza (or “flu”) type A (H1N1) virus. There is a human H5N1 virus circulating and causing seasonal influenza and in the past, very occasionally, H1N1 viruses from swine have infected humans. The specific type of the H1N1 virus causing illness now is new or “novel” and in the current outbreak it is clear that this virus is able to infect humans and be passed from person to person. Although part of the virus may have originated from pigs, there is no evidence that the current spread of infection is coming from that source.

How does the influenza A (H1N1) virus spread?
Spread of this new 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.

What should I do to keep from getting infected by the influenza A (H1N1) virus?
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 and avoid close contact with people who are sick.

What is a ‘pandemic’?
Influenza pandemics happen when a new human flu virus emerges and spreads rapidly across the globe because humans have no previous immunity against this virus.

Are we at risk of a pandemic?
No one can say whether or not the current situation would evolve into a severe pandemic. But whether it turns out to be a

catastrophic health event or little more than a bad flu season, it is important to be prepared for the worst.

What can you do?
Prepare yourself and your family immediately for a possible pandemic. This includes gathering and storing emergency supplies and adopting habits that will reduce the chance of you or your family getting infected and spreading it to others (for example, washing hands regularly, covering nose and mouth when you sneeze or cough, and not spitting in public).

What is the UN doing?
UN organizations are working to educate and inform staff about the threat of a pandemic and how best to prepare for it. Departments and offices have prepared business continuity plans and decided which functions are to be considered “critical” during a pandemic. Non-critical functions may be suspended for a period. In the event of a severe pandemic, most staff will be requested to remain at home and follow the UN’s Medical Guidelines.

ARE YOU AT RISK ?

Seasonal influenza
Everyone is at risk of getting seasonal influenza. It passes easily from person to person through droplets expelled from the nose and mouth of an infected person. These droplets can pass directly into the nose, mouth or eyes of a person who is nearby
5 Preventing and diagnosing influenza (less than 1 meter, or 3 feet, away) or indirectly when a person touches surfaces that droplets have fallen onto and then touches his or her nose, mouth or eyes before washing hands. Crowded, indoor environments may promote the chances of such transmission, which may explain the increase in respiratory infections during the winter months.
Seasonal influenza can lead to complications and even death. Most complications occur in people aged 65 years and over or in people with pre-existing medical conditions such as heart or lung disease and diabetes. Pregnant women, infants and very young children are also at increased risk of complications from influenza.
The World Health Organization (WHO) estimates that each year 3 million to 5 million people have severe cases of seasonal influenza worldwide, and 250,000 to 500,000 people die.

Pandemic Influenza
When a pandemic occurs, everyone will be at risk, not just frail or elderly people. Pandemic influenza passes from person to person just as easily and quickly as seasonal flu. But, unlike with seasonal flu, people will not be immune to this new virus, so more people will become infected. In addition, it is possible that even young and healthy people who do not normally suffer complications from seasonal flu may develop serious complications and even die in a pandemic.
It is important to know, however, that the majority of people who will develop a flu-like illness in a pandemic will recover and develop immunity to the new human virus.

WHAT SHOULD I KNOW ABOUT HUMAN INFL UENZA VIRUSES ?

Things you should know about human influenza viruses:
• They spread through infected droplets from breathing passages.
• Droplets are expelled by talking, spitting, coughing, sneezing.
• The droplets spread about 1 meter (3 feet) from the infected person, either directly to other people or indirectly through hands and other surfaces.
• The viruses can live for several hours on hard surfaces, or on cloth and paper.
• If healthy people touch infected hands, doorknobs, keyboards, telephones, etc., they can infect themselves by touching mouths, noses or eyes.
• Sometimes the viruses can spread through the air.
• An infected person is most likely to spread the virus when he or she has fever and a cough.
• It is possible that an infected person will spread the virus a day before showing signs of illness. 3
