Coronaviruses can survive in water, but there is a relationship with the concentration of sodium ions and other electrolytes in the water. Generally speaking, coronaviruses tend to live in an external environment similar to human body fluids, but if the ion concentration is too high or the water concentration is too low, it is not suitable for long-term survival of coronaviruses. Therefore, when killing coronavirus, you can use some active disinfectants containing high chlorine ions, such as 84 disinfectant or Jianzhu tablets are available. In addition, you can also use 75% ethanol, which can also play a role in killing the coronavirus. If you want to drink water, it is better to use boiled water to ensure that the coronavirus is killed.
