The use of ultraviolet light in the sun to kill the virus, baby clothes, bedding for this method. 3, is high temperature and boiling water to kill the virus. Baby’s tableware or bottles should be disinfected at high temperature every day, boiling water for more than 15 minutes, and do not mix and share with adults’ tableware. 4, is the chlorine disinfectant to eradicate the virus.
