It is generally possible to make a judgment based on aspects such as the pathogen and site of infection, symptom presentation, and transmission methods.

Influenza A is an acute respiratory infectious disease caused by the influenza A virus. It is characterized by sudden onset and rapid transmission, with main symptoms including high fever, chills, generalized muscle pain, fatigue, headache, dry cough, sore throat, and nasal congestion. Mycoplasma infection usually refers to pneumonia caused by Mycoplasma pneumoniae. Its symptoms are relatively mild and commonly include fever, cough, sore throat, headache, and fatigue. Compared to influenza A, mycoplasma infection typically presents with a more persistent cough and may be accompanied by wheezing and chest pain.

Influenza A mainly spreads through droplets, such as the small droplets released when coughing or sneezing, and can also be transmitted by touching surfaces contaminated with the virus. Mycoplasma infection primarily spreads through the air; for example, when an infected person coughs or sneezes, others may become infected by inhaling the released pathogens. Influenza A is generally susceptible, while mycoplasma infection can occur throughout the year, with higher incidence in autumn and winter.

The main treatment for influenza A involves antiviral medications, such as oseltamivir capsules. Mycoplasma infection can be treated with antibiotics such as azithromycin dispersible tablets or roxithromycin capsules. If symptoms of discomfort appear, it is recommended to seek medical attention at a hospital as soon as possible and follow medical instructions for treatment.
