J15.7

Clinical Causes: Infection with the bacterium Mycoplasma pneumoniae, which spreads through respiratory droplets from coughs or sneezes Close contact with infected individuals, such as in households or crowded settings Poor ventilation and hygiene can increase the risk of transmission It can occur at any age but is more common among school-aged children, teenagers, and young adults

Key Symptoms: Persistent dry cough that may worsen over time Fever, often low-grade but sometimes higher Sore throat and sore muscles Fatigue and weakness Headache and chills Chest discomfort or mild pain, especially during coughing Soupy or mucus-producing cough in some cases

Diagnosis Path: Chest X-rays to look for infiltrates in the lungs Laboratory tests such as blood tests to identify antibodies against Mycoplasma pneumoniae Polymerase chain reaction (PCR) testing of respiratory samples to detect bacterial DNA Serological tests for specific antibodies indicating recent or past infection

Treatment Protocols: Macrolide antibiotics like azithromycin or clarithromycin Doxycycline for certain age groups or allergies Supportive care such as rest, hydration, and over-the-counter medications for fever and discomfort Monitoring symptoms and follow-up medical assessments to ensure recovery
