Cough caused by Mycoplasma infection is contagious, but not so contagious that people with low resistance are susceptible. Mycoplasma pneumoniae is the smallest microorganism between bacteria and viruses, partially anaerobic and able to live independently. The mycoplasma present in respiratory secretions is transmitted to close contacts in the form of aerosolized particles with droplets, with an incubation period of 2 to 3 weeks, and is less contagious, mainly seen in children and adolescents. The disease is self-limiting, most of the symptoms are mild, and most cases can be cured without treatment. In order to prevent mycoplasma infection, you can drink more water, pay attention to nutritional balance, appropriate exercise to enhance resistance.
