The human body can still be re-infected after treatment and recovery from an STD infection. Only by changing high-risk behavior and maintaining a healthy lifestyle can you avoid re-infection in the future.
The correct use of condoms is the most effective method of STD/AIDS prevention, and condoms should be used throughout every sexual act.
If there are STD patients in your family, you should do a good job of cleaning and sanitation within the family to protect your family, especially girls, from infection. For example, laundry and bedding should be done regularly, underwear should not be washed together with children’s underwear, adults and children should sleep in separate beds, bath tubs should be used separately, and toilet rings should be scrubbed and disinfected every day.
