Z20: Contact with and exposure to communicable diseases

The group of conditions designated by the term "Contact with and exposure to communicable diseases" comprises a variety of illnesses that a person might encounter or get exposed to from another individual or environment harboring disease-causing microorganisms. This can happen through direct contact, like touching or close proximity, or indirect contact, like sharing objects or via airborne particles. Common symptoms often depend on the specific communicable disease but may include fever, cough, fatigue, muscle aches, and more. The progression of these conditions also varies, with some diseases causing chronic health issues or complications if left untreated, while others may resolve on their own. Various bodily systems can be affected, depending on the involved disease, ranging from the respiratory and gastrointestinal systems to the nervous and cardiovascular systems.
