Last Saturday afternoon, I received a message from Mrs. Yip, informing me that although the dengue fever epidemic has slowed down, there are still a few cases of dengue fever in the district, and I hope to expel mosquitoes in one go, and enter the households for breeding and inspection without spraying. There are six neighboring households in the area of enforcement, and the nursery is one of them. The head of the kindergarten said that he would only check and not spray, but if he found any tsetse, he would place spray cans directly, and he would be fined. Monday, the door is open.
