Health precautions advised by doctors

Those with breathing problems, the old, and young have been warned to take care because of the high amount of ash in the air caused by the Icelandic volcano. They should not for instance stay outside too long as conditions are similar to those when there is a serious smog, according to spokeswoman for the Association of Practitioners, Irena Kudrnovská. The Czech weather office said on Saturday the worst concentrations of the ash had drifted away from Czech Republic towards the Balkans. But the problem is far from over with fresh eruptions occurring.
