Defining Communicable Diseases Practice

Which statement BEST describes a treatment for a contagious illness? A. Bacteria, molds, or synthetic substances are used to create antibiotics, which are the most successful treatment for bacterial illnesses. B. Viral infections are best treated with antibiotics and vaccines, which are made from the pathogen that they are meant to treat. C. Treatment for fungal infections is made from different forms of molds, which can be taken orally or topically. D. Vaccines are made from molds and bacteria and are used to treat and prevent different viral infections.

A. Bacteria, molds, or synthetic substances are used to create antibiotics, which are the most successful treatment for bacterial illnesses.

A. strep throat is a virus and antibiotics are effective in treating viruses B. strep throat is a protozoan and antibiotics are often used to treat protozoan infections C. strep throat is a fungal infection that responds well to antibiotics D. strep throat is a bacterial infection that can be eradicated with antibiotic treatment

D. strep throat is a bacterial infection that can be eradicated with antibiotic treatment

An organism that carries a pathogen is called a __________. A. pathogen B. contaminant C. fungus D. vector

Describe three strategies that can be used to treat contagious infections.

Three strategies that can be used our antiviral drugs, anabiotic's, and vaccinations. or Strategies that can be used to treat contagious infections include medication to eradicate infection, alleviation of symptoms, and prevention. Bacterial, fungal, and protozoan infections can be treated with various medications. Bacterial infections are often treated with antibiotics that are selected based on the type and severity of the bacterial infection. Antiviral drugs are commonly used to treat respiratory viruses, herpes viruses, and HIV. Antifungal medications are either administered orally or topically depending on the severity and location of the fungal infection. Since there is no known cure for viral infections, medication can only treat the symptoms. This does provide some alleviation. Many infections, such as rubella and small pox, can be prevented through vaccinations.

Pathogens are disease-causing agents. True/False

True

Some pathogens can be transmitted between people and infected animals. True/False

True

Describe what a vaccine is made of and how it helps prevent infection.

Vaccines are made of mixtures that contain either parts of pathogens or whole pathogens that prepare the body's defenses to fight against the pathogens.

What are two uses for vaccines?

Vaccines, which are given for bacterial and viral infections, are mixtures that contain either part of pathogens or whole pathogens that prepare the body's defenses to fight against the pathogens. Active immunization helps the body create defenses against the pathogen before an infection occurs. Passive immunization is given to people with a weakened immune system or to those who have an existing infection. Its temporary effects will provide the body with the necessary defenses to fight the pathogen.

Explain the two ways that waterborne pathogens can be transmitted.

Waterborne pathogens can be transmitted either through ingesting contaminated food or water or bathing in contaminated water.
