Swine Flu Primer
What is H1N1? It's a virus which has gene segments from the swine, avian and human flu virus. Scientists have christened it influenza-a (h1n1) virus, commonly known as swine flu.

What's A Pandemic? An epidemic of infectious disease that spreads through human populations across a large region. On June 11, the who declared h1n1 a pandemic.

A novel influenza A (H1N1) virus has spread rapidly across the globe. Judging its pandemic potential is difficult with limited data, but nevertheless essential to inform appropriate health responses. By analyzing the outbreak in Mexico, early data on international spread, and viral genetic diversity, we make an early assessment of transmissibility and severity.

When World Health Organization (WHO) chief Margaret Chan declared last week that for the first time in more than 40 years the world is facing an influenza pandemic, she simply stated what everybody already knew.

Sri Lankan health officials yesterday detected a second patient with swine flu (H1N1). The second patient is a six-year-old boy who was a cousin of the first patient, an eight-year-old boy, and arrived in Sri Lanka with the same family.
