Scorpions stung 500 people in Egypt. Heavy rain brought hundreds of scorpions into the streets and people's homes this week. Many people went to hospital. Doctors gave them injections and the people went home. Some people were in pain, had fever and were vomiting. Hospitals are on alert for more people with stings. A weather expert said farmers should be careful in their fields. He also asked people to be careful of snakes.

People are worried because the scorpions are dangerous. They are Arabian fat-tailed scorpions. Their nickname is "man-killer". Their venom can kill a human in an hour. The scorpions live in the mountains. The weather expert said people should wear proper shoes. He said scorpion numbers would go down after the rainwater dried up. Less than one per cent of the world's scorpion species are deadly.
