Medical experts reminded minors to take precautions, such as getting vaccinated, against seasonal respiratory pathogens to boost disease resistance as this time of the year, the spread of diseases is at a high level.
Children suffering from recurrent respiratory infections may also be given immunomodulators under the guidance of doctors, they said in a report published by Life Times on Wednesday.
Immunomodulators function by mimicking the stimulation of pathogens, promoting the activation and proliferation of immune cells, thereby strengthening immune memory and function, and improving the body's ability to recognize and eliminate pathogens.
Spring is a prime time for the spread of allergens and pathogens, said the experts, and children's gathering on school campuses after the new semester opens makes contagious diseases more rampant.
Antibodies are usually produced within human bodies one to two weeks after infection, but exposure to a pathogen again before the generation of antibodies can still lead to a new round of infection.
Children are more vulnerable to contagious pathogens as their immunity usually reaches the average adult level after 7 years old.
