Disease Overview：Postinfectious Cough（PIC）
Post-infectious cough (PIC) is a common respiratory condition characterized by persistent, non-productive cough lasting three to eight weeks following an acute upper or lower respiratory tract infection—most frequently viral in origin, such as rhinovirus, influenza, or SARS-CoV-2. It arises from airway inflammation, transient bronchial hyperresponsiveness, and neural sensitization of the cough reflex arc, rather than ongoing infection or structural pathology. Diagnosis requires careful exclusion of alternative etiologies—including asthma, eosinophilic bronchitis, gastroesophageal reflux disease (GERD), and postnasal drip—through clinical evaluation, spirometry, fractional exhaled nitric oxide (FeNO) testing, and, when indicated, high-resolution chest CT or bronchoscopy. Management focuses on symptomatic relief and modulation of neurogenic inflammation; evidence-supported interventions include low-dose inhaled corticosteroids, neuromodulators like gabapentin or amitriptyline, and speech-language pathology–guided cough suppression techniques.
China offers distinct advantages for PIC management: leading respiratory centers—such as Peking Union Medical College Hospital and Shanghai Ruijin Hospital—employ multidisciplinary teams with deep expertise in chronic cough phenotyping and refractory airway disorders. Advanced diagnostics including impulse oscillometry, capsaicin cough challenge testing, and real-time laryngopharyngeal pH monitoring are widely available. Clinical outcomes reflect high resolution rates (>85% within 12 weeks) in published cohort studies. Treatment costs remain significantly lower than in the US or Western Europe—often 40–60% less—without compromising diagnostic rigor or therapeutic precision. As a dedicated medical tourism agency, we facilitate seamless international care: verifying physician credentials, coordinating appointments at JCI-accredited hospitals, providing itemized, transparent pricing in advance, and offering end-to-end support—from visa assistance and medical translation to post-consultation follow-up.

Pricing & Service Differences: International / VIP Dept vs. Regular Clinic
International Medical Services (IMS / VIP Departments) at Grade-3A public hospitals and private international clinics operate under self-regulated VIP fee schedules. Fees are higher than standard public clinics (which are subsidized solely for domestic citizens and do not accept overseas insurances). In exchange, international patients receive 6 exclusive medical privileges:
