Sinus congestion, coughing and sore throats are examples of inflammation of the upper respiratory airway.
An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...

Diagnosis is often based on symptoms and physical examination. [8] Chest X-rays, blood tests, and culture of the sputum may help confirm the diagnosis. [8]
Reducing airborne transmission of COVID-19 indoors (video) This mode of transmission occurs via an infected person breathing out the virus, which is then carried by the air to a person nearby, or to someone across a room, who then breathes the virus in. Attempts to reduce airborne transmission act on one or more of these steps in transmission. [48]
