Solutions

What are Infectious Diseases?

1) Infectious diseases are NOT caused by:
a. Bacteria
b. Viruses
c. Your genesd. Fungi
e. Parasites

Infectious diseases are only caused by things that can infect you. These things can be passed between people, animals, or plants. You are born with a certain genetic background that you cannot infect other people with, so your genes are not a cause of infectious disease. The other choices listed are all pathogens which can cause infectious disease.

2) True or False: You will always know when you get infected by a pathogen.

False. Most pathogens are microscopic and you will not know you have been infected. If you don't show any disease symptoms there is no way to know if you were infected (unless you have lab tests done).

3) Infectious diseases can sometimes spread around the world to several continents and cause severe disease. This is called a:

a. Panoply
b. Pandemicc. Panacea
d. Panache
e. Panchax

Pandemic is a term for when an infectious disease has spread to several continents and causes severe disease. Panoply is an impressive collection of things. Panacea is a solution or remedy for all ills and difficulties. Panache is a flamboyant and confident manner. Panchax is a type of fish.

4) Which of the following choices was the cause of the Black Death in Europe in the 1300s?

a. Mycobacteria tuberculosis
b. Yersinia pestisc. Influenza A virus
d. HIV
e. Rabies virus

The black death, or bubonic plague, was caused by the Yersinia pestis bacteria. The other choices are all pathogens, but scientists have found evidence that Yersinia pestis bacteria killed large numbers of people in the 1300s.

5) True or False: Bioweapons are weapons designed to kill pathogens.

False. Bioweapons are any pathogen that has been turned into or used as a weapon.

Bacteria

1) Bacteria are found________.

a. on the surface of plants and animals
b. inside our intestines
c. on our skin
d. on the surface of non-living things
e. all of the above

The world is full of bacteria, and they are found all over the place including in us, on us, and around us on other plants and animals.

2) Drug resistance is caused by_________________.

a. using too many different antibiotics
b. too much use of a single antibioticc. too many bacteria
d. too few bacteria
e. not using antibiotics

Too much use by a single antibiotic can cause resistant bacteria to be naturally selected for. Using many different antibiotics can limit this from happening. The number of bacteria does not play a role. Also, drug resistance cannot occur if there is no drug being used.

3) Which of the following is not a species of bacteria?

a. Escherichia coli
b. Yersinia pestis
c. Mycobacterium tuberculosis
d. Malaria malariae. Streptococcus pyogenes

Malaria malaria is not a species of bacteria. It is not even a real thing. The Malaria disease is caused by Plasodium (we will discuss this in a later section). All the other things are species of bacteria listed in this section.

4) Tuberculosis is primarily an infection of which organ?

a. Liver
b. Intestine
c. Brain
d. Skin
e. Lungs

Tuberculosis is primarily a lung infection. Symptoms can affect the entire body, but the main organ affected is the lung.
5) True or False: All bacteria are dangerous pathogens.

False. Many bacteria are either harmless or can actually have positive effects. The bacteria in our gut are required for healthy digestion and are likely also important for many diseases.

Viruses

1) Which domain of life are viruses a part of?

a. Bacteria
b. Eukarya
c. Archaea
d. All of the above
e. None of the above
Viruses are not considered to be alive since they cannot reproduce without a host; therefore, they do not belong to any domain of life.

2) Viral infections are combated with ____________ and ____________.

a. Antibiotics and Antivirals
b. Antibiotics and Vaccines
c. Antivirals and Vaccinesd. Antibiotics only
e. None of the above.

Antivirals and vaccines are the top choices to combat viruses. Antibiotics are ineffective against viruses.
3) What infectious disease currently kills the most people on the planet?

a. AIDS
b. Malaria
c. Smallpox
d. Rabies
e. Chickenpox

AIDS kills more people each year than any other infectious disease. It kills nearly 2 million people every year.

4) Which two diseases are caused by the Varicella zoster virus?

a. Strep throat and flesh eating bacteria
b. AIDS and the flu
c. Chickenpox and Shinglesd. Chickenpox and Monkeypox
e. Malaria and Rabies
Chickenpox and Shingles are both caused by the Varicella zoster virus. Strep throat and flesh eating bacteria are caused by Group A Streptococcus. AIDS , flu, Malaria, Rabies, and monkeypox are not caused by Varicella.

5) Why is mononucleosis called "the kissing disease?"

a. It makes you want to kiss people.
b. It causes excess saliva.
c. It is only spread by saliva.d. It makes your lips very dry.
e. It causes a red rash that is shaped like lips all over your body.

Mono is spread by saliva. It does not cause excess saliva, dry lips, a lip-shaped rash, or a strong desire to kiss other people.

Fungi and Parasite Infections

1) Which of the following is NOT caused by fungus?
a. Athlete's foot
b. Malariac. Yeast Infection
d. Aspergillosis
e. Jock itch

Malaria is cause by the plasmodium parasite and is not caused by a fungus.

2) Which of the following is the most common disease caused by a parasite?

a. Malaria

b. Hookworm
c. Roundworm
d. Brain eating ameba
e. HIV

Malaria is the leading cause of parasitic disease. Roundworm is the leading cause of helminth (worm) infections followed by hookworm. Brain-eating amoeba is rare. HIV is not caused by a parasite.

3) True or False: Fungi are commonly found on human skin.

True. Fungi are found throughout the environment, including on human skin.

4) True or False: Yeast infections are a rare and dangerous disease.

False. It is estimated that 75% of women in the United States will have a vaginal yeast infection at some point. They can be treated with antifungal medication.

5) How many people are infected by Roundworm around the world?

a. 807
b. 8070
c. 80,700
d. 807,000
e. 807,000,000

Roundworm causes a huge number of infections throughout the world. With 7 billion people on the planet and 807 million people infected that means 1 out of every 9 people is infected. Now, that's a lot of roundworms.
