Are some people more at risk?

More study is needed to determine if some populations (i.e. younger or older people, or people with other medical conditions) could be affected by the outbreak, of if they are at higher risk for severe illness. WHO recommends that everyone take precautions to prevent the spread of infection.

Are there any special recommendations for pregnant women?

Yes, they are vulnerable. Like everyone, they should take all the necessary precautions.

How do people become infected with influenza A(H1N1)?

Outbreaks in humans are now occurring from human-to-human transmission. When infected people cough or sneeze, infected droplets get on their hands, drop onto surfaces, or are dispersed into the air. Another person can breathe in contaminated air, or touch infected hands or surfaces, and be exposed. To prevent spread, people should cover their mouth and nose with a tissue when coughing, and wash their hands regularly.

What are the signs and symptoms of infection?

Early signs of influenza A(H1N1) are flu-like, including fever, cough, headache, muscle and joint pain, sore throat and runny nose, and sometimes vomiting or diarrhoea. 

Regarding study of the first outbreak, have you received any feedback from the WHO team sent to Mexico to investigate the outbreak?

Teams are already sending epidemiological evidence but we will know more over the next few days.

The main route of transmission of the new influenza A(H1N1) virus seems to be similar to seasonal influenza, via droplets that are expelled by speaking, sneezing or coughing. You can prevent getting infected by avoiding close contact with people who show influenza-like symptoms (trying to maintain a distance of about 1 metre if possible) and taking the following measures: 

• avoid touching your mouth and nose; 
• clean hands thoroughly with soap and water, or cleanse them with an alcohol-based hand rub on a regular basis (especially if touching the mouth and nose, or surfaces that are potentially contaminated); 
• avoid close contact with people who might be ill; 
• 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.
