Is white lung contagious?

Generally, if white lung is caused by infectious pathogens, it may be contagious. If white lung results from non-infectious factors, it typically is not transmissible. Consultation with a physician is recommended if necessary. Detailed analysis is as follows:

When white lung is caused by infectious pathogens, such as in cases of pneumonia resulting from infection with the novel coronavirus, there is a risk of transmission. These viruses can spread via droplets when an infected person coughs, sneezes, or talks, expelling numerous virus-containing droplets. Healthy individuals who inhale these droplets may allow the virus to invade their respiratory tract, potentially leading to white lung. Additionally, in relatively enclosed and poorly ventilated spaces, the virus may form aerosols that remain suspended for extended periods, increasing the risk of covert transmission.

If white lung arises from non-infectious causes, such as radiation injury, inhalation of irritating chemical substances, or autoimmune diseases affecting the lungs, there is no transmission of pathogens involved. In such cases, close contact with the affected individual poses no risk of infection to others.

During outbreaks of respiratory infectious diseases, avoid crowded places as much as possible. If attendance in such places is unavoidable, wear a medical mask properly to implement effective protection and block the transmission route of droplets.
