Hemoptysis is the presence of fresh blood in secretions coming from the respiratory tract (coughing, spitting). Light hemoptysis most often results from a mild infection of the bronchi or lungs. Sometimes, however, hemoptysis can be associated with more serious problems, such as lung cancer, pulmonary embolism, tuberculosis or an overdose of anticoagulants.

Hemoptysis is an unusual symptom of COVID-19. Less than 1% of patients infected with SARS-CoV-2 have hemoptysis.

Hot zone

A hot zone is a section of a facility (sometimes an entire facility or even a city district) where there is a high risk of contamination by patients with an infectious disease. All individuals entering a hot zone must respect appropriate protective measures. By analogy, “cold zone” and “warm zone” are used to refer to areas where there is no infected individual or only individuals suspected of having an infection.
