Are patients with intoxications and incubating infections (excluding flu) considered to be contagious?

Patients with intoxications and incubating infections (excluding flu) are considered to be contagious because they may spread pathogens before they exhibit symptoms. Contagiousness refers to the ability of a disease to be transmitted from one individual to another, and for many infectious diseases, this can occur during the incubation period. This period is when the pathogen is present in the host, multiplying, yet the host does not yet show clinical signs of the illness.

In specific cases, certain infections can have a communicable phase even before symptoms appear, which emphasizes the need for precautions in managing such patients. This understanding is critical in the context of biological threats and the management of potential outbreaks to prevent further transmission.
