A positive Chlamydia pneumoniae suggests a chlamydial infection, which is an atypical pneumonia that is generally not serious and relatively easy to treat. Chlamydia pneumonia is spread by airborne droplets, and is easily diagnosed in the elderly, malnourished or immunocompromised. The latter is not suitable for adolescents under the age of 18. If the dose of antibiotics is too small or the duration is too short, the symptoms often last for a long time, so care must be taken. The application of antibiotic treatment should also pay attention to general treatment, to strengthen care, pay attention to rest, keep the room air fresh, pay attention to heat preservation, do not catch cold, keep the respiratory tract open, irritable people can be given a small amount of sedatives, to prevent aggravation of hypoxia. Give a high-calorie, vitamin-rich easily digestible liquid or semi-liquid diet, avoid tobacco, alcohol and spicy stimulating food, drink plenty of water, and eat more fresh vegetables and fruits. So, there is no need to be anxious about Chlamydia pneumoniae infection. If the infection is mild, there are no complications and your resistance is good, you can get rid of it without treatment and it can usually heal on its own. If there are more serious symptoms or complications that affect normal work or life, you should seek medical attention and cooperate with your doctor for active treatment to shorten the course of the disease and promote early recovery.
