Whooping Cough Treatment Market Outlook:
Whooping Cough Treatment Market size was valued at USD 1.6 billion in 2025 and is projected to reach approximately USD 2.8 billion by the end of 2035, rising at a CAGR of 5.4% during the forecast period, 2026-2035. In 2026, the industry size of whooping cough treatment is assessed at USD 1.7 billion.
The whooping cough treatment market is driven by a steadily rising patient population with high annual incidence rates driving continuous pharmaceutical and medical device distribution. The CDC report in March 2024, the reported pertussis cases in 2023 is more than 5,611, putting a regular demand on antibiotics such as azithromycin and macrolides and supportive care devices like oxygen concentrators and pulse oximeters. The API supply chain of first-line medicines is global, and a portion of the manufacturing is currently centered in Asia. This generates dependencies and vulnerabilities and has been evidenced in API supply interruptions.
International trade is a critical component of the market's supply chain. The U.S. is a net importer of both finished antibiotic formulations and their underlying APIs. On the other hand, the OEC data in 2023 states that China is the leading exporter of antibiotics worth USD 4.84 billion. For instance, U.S. Food and Drug Administration documentation indicates a heavy reliance on foreign sources for essential medicine manufacturing, including drugs critical for treating respiratory infections. The assembly and packaging of final drug products are often conducted domestically or in partner nations with stringent regulatory oversight.
