Epidemiology Scavenger Hunt

Find an example infectious disease for each of the term(s) or concept(s) below. Give the name of the disease and its causal agent and whether it is viral , prion, bacterial, fungal, protozoan, or helminthic. All of the diseases must be infectious diseases.

1. A communicable disease

2. A non-communicable disease

3. Reservoir is restricted to humans.

4. Reservoir is a non-human animal, disease is zoonotic

5. Reservoir is primarily environmental

6. Human carriers are usually symptomatic

7. Human carriers are often asymptomatic

8. Find the morbidity rate of a disease caused by a protozoan

9. Find the incidence of a blood-borne viral disease

Solution

1. A communicable disease - Influenza – Influenza A or B virus – Viral

2. A non-communicable disease -A non communicable disease can not be infectious – example of non-communicable disease- Diabetes

3. Reservoir is restricted to humans.- Poliomyelitis- Polio virus- Viral

4. Reservoir is a non-human animal, disease is zoonotic -Plague (reservoir – Rodents)- Yersinia pestis - Bacterial

5. Reservoir is primarily environmental- Legionnaires disease -Legionella pneumophila - Bacterial

6. Human carriers are usually symptomatic-Malaria- Plasmodium falciparum - Protozoan

7. Human carriers are often asymptomatic- Typhoid fever – Salmonella enteric -Bacterial

8. Find the morbidity rate of a disease caused by a protozoan -Malaria (20%)

9. Find the incidence of a blood-borne viral disease - Hepatitis B - HB Virus - viral, incidence varies from year to year and by geographical locations
