1. Epidemic disease: When many people in a given area acquire the disease in a relatively short period of time.

2. Droplet infection: Occurs when microorganisms are carried on liquid drops from a cough or sneeze.

3. Thallus: macroscopic mold colony that is composed of a mass of strands called mycelia

4. Reducing media: special media that provide better anaerobic culturing conditions.

5. Degerming: Removal of microbes by mechanical means. Example: hand washing, alcohol swabbing at site injections.

6. Sanitization: Removal of pathogens from objects to meet public health standards.

7. Sterilization: Destruction of all microorganisms and viruses in or on an object.

8. Synergism: A process that allow one drug to sometimes enhance the effect of a second drug.

9. Dynoflagellates: Group of alveolates, unicellular microbes that have photosynthetic pigments, such as carotene an chlorophylls.

10. Arthropod vectors: Animals that carry pathogens an have segmented bodies, hard external skeletons, and jointed legs.

Encounters

Hand washing is one of the best way to prevent diseases. It was implemented by Ignaz Semmelweis in the early 1800s. The death rate of women (after childbirth) in Semmeilweis department at the Vienna General Hospital was high. Physicians and male medical students were not performing proper hand hygiene when dealing with patients. They moved from treating patients to patients without washing their hands. They would move from performing autopsies to delivering babies. 

Hand washing requires water and soap. It is important to wash hands after you remove your gloves. Wash your hands after using the restroom, before and after preparing food, taking care of patients, after sneezing, coughing, shaking hands with others.

Investigations

Why get the flu after getting the flu vaccine?

Vaccines are one of the best prevention of a disease by providing active immunity. People with weak immune system should consider taking the flu shot. After the vaccination, one might have a mild case of the flu (better than worse). After the flu shot, a person can get sick before the vaccine provide protection to the body. Also; a person may get a virus whose protection is not included in the seasonal flu shot. The flu shot can cause side effects (flu-like symptoms) that are sometimes mistaken as the flu.
