Respiratory tract infections

Identifying and differentiating respiratory pathogens is critical to effective infection management

Acute respiratory infections are one of the leading causes of death and disability in the world.1

Respiratory tract infections (RTIs) include both upper tract infections, like the common cold, and lower tract infections, such as pneumonia, bronchitis, and tuberculosis. While most upper respiratory infections can resolve on their own, lower respiratory tract infections can pose a substantial health challenge, especially for infants, the elderly, and the immunocompromised.2,3

Respiratory infections are caused by a wide variety of pathogens. Viruses like influenza A and B, respiratory syncytial virus (RSV), and Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) command much attention, but similar symptoms may also be presented by other agents, including bacteria like Streptococcus and Mycobacterium tuberculosis (MTB, TB).

Roche’s role in respiratory tract infection detection

As a global leader in vitro diagnostics, Roche invests heavily in research and development to deliver impactful technologies that address real-world needs.

To address the prevalence, complexity, and variety of respiratory tract infections, Roche offers a range of tests and technologies to support the detection and management of respiratory disease—for example, with the world’s first commercial PCR test to detect SARS-CoV-2 (the virus that causes COVID-19) and its respective antibody test.

Targeting tuberculosis—one of the world's most common infectious disease.6

To address the burden Mycobacterium tuberculosis places on healthcare systems and patients, Roche partners with national governments, local healthcare facilities, communities and international agencies to provide increased access to diagnostics in countries hardest hit by the disease.

As respiratory infections continue to pose a global challenge, Roche remains committed to supporting laboratories and testing centers around the world with innovative solutions that enable them to provide patients and their clinicians with a reliable diagnosis when and where it is needed most.
