Answer:
A communicable disease is a disease that spreads from one person or animal to another. Pathogens such as viruses, bacteria, and fungi cause these diseases
A communicable disease is any disease that passes between people or animals. People sometimes refer to communicable diseases as “infectious” or “transmissible” diseases.
Pathogens, including bacteria, viruses, fungi, and protists, cause communicable diseases.
A person may develop a communicable disease after becoming infected by the pathogen. This may happen through:
direct contact with a person carrying the pathogen
contact with contaminated fluids, such as blood, mucus, or saliva
inhaling contaminated droplets from another person’s cough or sneeze
receiving a bite from an animal or insect carrying the pathogen
consuming contaminated water or foods
Once a pathogen has entered a person’s body, it will begin replicating. The individual may then begin to experience symptoms.
Some symptoms are a direct result of the pathogen damaging the body’s cells. Others are due to the body’s immune response to the infection.
Communicable diseases are usually mild, and symptoms pass after a few days. However, some can be serious and potentially life threatening.
Types and symptoms
Four main types of pathogens cause infection: Viruses, bacteria, fungi, and protists.
Viruses
Viruses are tiny pathogens that contain genetic material. Unlike other pathogens, they lack the complex structure of a cell. To replicate, they must enter the cells of other living beings. Once inside, they use the cell’s machinery to make copies of themselves.
Some different viruses include:
Rhinoviruses
Rhinoviruses are a group of viruses that are responsible for the common cold. Symptoms of a cold may include:
a stuffy or runny nose
sore throat
headache
A person can catch a rhinovirus by inhaling contaminated droplets from the cough or sneeze of another person.
Similarly, rhinoviruses spread by people touching their nose, eyes, or mouth after touching items or surfaces that have come into contact with the virus.
Influenza
Influenza viruses are infections that attack the respiratory system. Some potential symptoms include:
fever or chills
stuffy or runny nose
sore throat
cough
headaches
muscle or body aches
fatigue
A person can catch influenza viruses in the same way they may catch rhinoviruses.
HIV
HIV attacks the immune system of its host. This makes the person vulnerable to other infections and diseases.
A person can contract HIV as a result of contact with blood or other body fluids containing the virus.
The symptoms of HIV may develop gradually and in stages. They can include:
fever
chills
rash
mouth sores
sore throat
swollen lymph nodes
night sweats
muscle aches
fatigue
The only way a person can be certain they have HIV is to have an HIV test.
Although there is no cure for HIV, medications can help to keep the virus under control. Without such treatment, HIV can develop into AIDS.
