Thirty years ago, it was normal to have lice in the countryside. Many of them may have had lice when they were young after 80s. However, many post-90s generation may have no impression of what lice are, let alone post-00 generation.
The characteristics of lice are small and black, and they like to hide in the hiding place of hair or clothes. Lice still come out to bite people from time to time, which itches terribly. At that time, the common method for people to catch lice was to comb their hair repeatedly with a very dense comb, that is, a very dense comb to comb out the lice hidden in their hair. This method is only effective for big lice, but basically not for that kind of eggs.
Thirty years ago, the biggest reason why people in rural areas were prone to lice was the poor sanitary conditions, and many people did not pay attention to personal hygiene. In particular, children run around, breeding lice and easily infecting others.
At that time, the living standard in rural areas was limited and the sanitary conditions were poor. Many villages have water problems, so they have to go far away to get well water. At that time, people worked hard to solve the problem of food and clothing, and paid little attention to personal hygiene conditions. In mountainous areas, water use is relatively tight. In the northern region, when the weather is cold in winter, you can only take a bath once a winter, which is easy to grow lice. At that time, there were not many cleaning products that could be used to wash your hair. Shampoo, shower gel and soap were invisible, and children were too lazy to wash their hair, which all bred the environment for lice to grow.
In the countryside, I also like to keep a few pigs, chickens or other dogs and cats. These animals are a good environment for lice to grow. They carry parasites such as fleas, lice and bacteria. Moreover, cats and dogs like to rub people, which makes lice easily transmitted to people.
For another example, in the past, children in rural areas liked to cross the grass, climb the hillside, catch insects, get into the mud and have a runny nose. They don't advocate personal hygiene. After a long time, it is easy to breed lice and then infect others.
However, the conditions in rural areas are completely different from those in the past. Since the reform and opening up, the living conditions in rural areas have also undergone earth-shaking changes. Almost every village has access to roads and every family has running water. Instead of burning wood for cooking, they switched to natural gas. Moreover, people in the new countryside are responsible for cleaning every day, and farmers' lives are cleaner and more refined than before.
Rural areas have also formed a habit of paying attention to personal hygiene. Wash your face and brush your teeth, wash your hair and take a bath every day. Every roof has a solar water heater or an electric water heater, and there are many cleaning and nursing products, such as shampoo and shower gel, which can remove lice and keep people clean.
In addition, there are no soil farms in rural areas, and there are few chickens and pigs. Nature rarely sees lice. Even if there are lice, it is cured to go to rural health centers to get medicine. This is why there are few lice in rural areas after 30 years.
