The differences between iodophor and povidone iodine are mainly as follows: First, the object of use is different, as iodophor is generally used as a disinfectant for the skin, while povidone iodine is generally used as a disinfectant for the skin mucosa. Secondly, the sterilization effect is also different, as iodophor is much stronger than povidone iodine. Third, if used for the safety of the population, iodophor is safer than povidone iodine and has no adverse side effects. Povidone iodine may cause allergic reactions in human skin and is not recommended for pregnant women and newborns. Iodine volts are safer to use on newborns or pregnant women. Also povidone iodine has an oral solution suitable for livestock, so it is generally used for disinfection of turtles. Iodophor and povidone iodine are disinfectants, both of which have a strong bactericidal effect on viruses or bacteria, but iodophor is generally used more in clinical practice, and povidone iodine is relatively less widely used.
