Moscow has been shrouded in acrid smoke from the worst forest fires since 1972.
Carbon monoxide levels in the Russian capital are currently six times over the safe limit. Doctors have warned people are inhaling the equivalent of 40 cigarettes every few hours.
On a visit to the stricken region, Prime Minister Vladimir Putin said the situation had stabilised but was still dangerous.
He has promised the state will help rebuild all homes destroyed, and has pledged generous compensation.
After losing everything, many people are worried about how they will survive when the bitterly cold Russian winter begins to bite.
