HBV is a blood-borne disease and is transmitted primarily through blood (e.g., unsafe injections), mother-to-child, and sexual contact. Epidemiological and experimental studies have not found that HBV can be transmitted by blood-sucking insects (mosquitoes, bedbugs, etc.). If you receive hepatitis B vaccine and have anti-HBs >10 mIU/mL, you are protected, so you will not be infected if you live with a hepatitis B patient. The first hospital of Henan College of Traditional Chinese Medicine, Ai Research Center, Du Lei HBV is highly resistant, but HBV can be inactivated by boiling at 65°C for 10 h, boiling for 10 min or high pressure steam. ethylene oxide, glutaraldehyde, peroxyacetic acid and iodine volt are also effective in inactivating HBV and can be used to disinfect items used by hepatitis B patients depending on the situation.
