Preventive measures and key points of virus:
90% of most babies' colds are caused by upper respiratory tract infection, so if you want your baby to prevent virus infection as much as possible, you should try to keep your baby away from dense crowds, especially some heavily polluted environments, especially some smoking places, which are easy to weaken your baby's respiratory defense ability and let virus pathogens multiply.
In addition, in daily life, try to make your baby nutritious and take part in some physical exercise properly. For virus infection with mild symptoms, parents should always observe the baby's mental state. For virus infection with aggravated symptoms, they should immediately take the baby to the hospital for necessary examination and treatment, so as not to delay the illness.
