Presentation Transcript

What is swine flu? : 

What is swine flu?

Slide 3: 

Swine Influenza (swine flu) is a respiratory disease of pigs caused by Type A influenza viruses that causes regular outbreaks in pigs. Swine flu viruses have been reported to spread from person-to-person, but in the past, this transmission was limited and not sustained beyond three people.

Is the current swine flu virus contagious? : 

Is the current swine flu virus contagious?

Slide 6: 

Various international agencies (US Centers for Disease Control & Prevention, World Health Organization) have determined that this swine influenza A (H1N1) virus is contagious and is spreading from human to human. WHO has escalated the world Pandemic Phase from Phase 3 to Phase 4 (in a 6-scale Phase), indicating that a worldwide pandemic due to swine flu H1N1 is possible.

What are the signs and symptoms of swine flu in people? : 

What are the signs and symptoms of swine flu in people?

Slide 9: 

The symptoms of swine flu in people are similar to the symptoms of regular human flu and include fever, cough, sore throat, body aches, headache, chills and fatigue. Some people have reported diarrhea and vomiting associated with swine flu. In the past, severe illness (pneumonia and respiratory failure) and deaths have been reported with swine flu infection in people. Like seasonal flu, swine flu may cause a worsening of underlying chronic medical conditions.

How does swine flu spread? : 

How does swine flu spread?

Slide 12: 

Spread of this swine 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 live flu viruses on it and then touching their mouth or nose.

How are human infections with swine influenza diagnosed? : 

How are human infections with swine influenza diagnosed?

Slide 15: 

To diagnose swine influenza A infection, a respiratory specimen would generally need to be collected within the first 4 to 5 days of illness (when an infected person is most likely to be shedding virus). However, some persons, especially children, may shed virus for 10 days or longer. Identification as a swine flu influenza A virus requires sending the specimen to a hospital laboratory for testing.

How can someone with the flu infect someone else? : 

How can someone with the flu infect someone else?

Slide 17: 

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.

How long can an infected person spread swine flu to others? : 

How long can an infected person spread swine flu to others?

Slide 20: 

People with swine 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.

Are there medicines to treat swine flu? : 

Are there medicines to treat swine flu?

Slide 24: 

Yes. The US CDC recommends the use of oseltamivir (Tamiflu®) or zanamivir (Relenza®) for the treatment and/or prevention of infection with these swine 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).

Is there a vaccine for Pandemic Flu? : 

Is there a vaccine for Pandemic Flu?

Slide 27: 

Because the virus is new, there will be no vaccine ready to protect against pandemic flu. Vaccine against Swine Flu virus H1N1 needs at least 6-12 months to be produced. Seasonal flu vaccine or past flu immunization will not provide protection.

What surfaces are most likely to be sources of contamination? : 

What surfaces are most likely to be sources of contamination?

Slide 30: 

The virus can be spread when a person touches something that is contaminated with the virus and then touches his or her eyes, nose, or mouth. Droplets from a cough or sneeze of an infected person move through the air. The virus can then be spread when a person touches respiratory droplets from another person on a surface like a desk, doorknob, child’s toy or phone handset and then touches their own eyes, mouth or nose before washing their hands.

What is the best way to keep from spreading the virus through coughing or sneezing? : 

What is the best way to keep from spreading the virus through coughing or sneezing?

Slide 33: 

If you are sick, limit your contact with other people as much as possible. Do not go to work or school if ill. Cover your mouth and nose with a tissue when coughing or sneezing. It may prevent those around you from getting sick. Put your used tissue in the waste basket. Cover your cough or sneeze if you do not have a tissue. Then, clean your hands, and do so every time you cough or sneeze.

In children emergency warning signs that need urgent medical attention include: : 

In children emergency warning signs that need urgent medical attention include:

Slide 36: 

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: - : 

In adults, emergency warning signs that need urgent medical attention include: -

Slide 39: 

Difficulty breathing or shortness of breath Pain or pressure in the chest or abdomen Sudden dizziness Confusion Severe or persistent vomiting

Can people catch swine flu from eating pork? : 

Can people catch swine flu from eating pork?

Slide 42: 

No, Swine influenza viruses are not transmitted by food. You can not get swine influenza from eating pork or pork products. Eating properly handled and cooked pork and pork products is safe. Cooking pork to an internal temperature of 160°F (72°C) kills the swine flu virus as it does other bacteria and viruses.
