World reaction to swine flu

Mexican health authorities have dispatched portable clinics, known as Health Caravans, around Mexico City to offer medical advice on swine flu.

The flu has spread to countries as far afield as New Zealand and Spain and the World Health Organisation has raised the alert to level five - a strong signal a pandemic is imminent.

Meanwhile in Egypt, the government plans to cull its pig population, amid swine flu pandemic fears. Pig farmers are to be compensated following the cull.
