Introduction

Under normal circumstances, mycoplasma pneumonia is contagious and primarily spreads through respiratory droplets and direct contact. When a person with mycoplasma pneumonia coughs, sneezes, or talks, individuals nearby may become infected by inhaling droplets containing the pathogen. Close contact between healthy individuals and those with mycoplasma pneumonia can also lead to transmission of Mycoplasma pneumoniae.

Generally, mycoplasma pneumonia is contagious and primarily spreads through respiratory droplets and direct contact. The details are as follows:

Droplet transmission is the main route of spread for mycoplasma pneumonia. When a person with mycoplasma pneumonia coughs, sneezes, or talks, droplets containing Mycoplasma pneumoniae are produced. These droplets can remain suspended in the air briefly, and individuals who inhale these droplets may become infected.

In addition, close contact between healthy individuals and patients with mycoplasma pneumonia—such as sharing towels, eating utensils, toys, or coming into contact with the patient's secretions—can also lead to transmission, especially if proper personal hygiene is not maintained and one subsequently touches their mouth, nose, or eyes.

It is recommended to maintain good personal hygiene habits in daily life, such as frequent handwashing and ensuring indoor ventilation, and to avoid crowded places as much as possible, which can help reduce the risk of developing mycoplasma pneumonia.

Under normal circumstances, Mycoplasma pneumoniae is a microorganism that lies between bacteria and viruses. Mycoplasma pneumoniae is a small microorganism that exists between ciliated epithelial cells. It adheres to the surface of host respiratory epithelial cells through neuraminic acid receptor sites on the cell membrane, inhibiting ciliary activity and damaging epithelial cells. It is generally recommended to maintain good indoor air circulation and keep warm.

Can Mycoplasma pneumonia cause white lung?

Mycoplasma pneumoniae may lead to white lung. In some special cases, Mycoplasma pneumoniae infection might cause severe pulmonary lesions, resulting in white lung. If Mycoplasma pneumoniae infection is not timely controlled, the inflammation may continue to worsen, with large amounts of inflammatory exudates accumulating in the alveoli and pulmonary interstitium. When the exudates reach a certain level, the lungs may exhibit white areas on imaging studies.
