Answer all of the question, will give brainliest for correct answers. do not guess , i will report (sorry, some people just do this for points)
methicillin-resistant staphylococcus aureus (mrsa) is an infectious disease that often appears in news headlines. research this disease and complete the following:
1. define the three words in mrsa: methicillin, resistant, and staphylococcus aureus.
2. describe the signs and symptoms of a mrsa infection of the skin. complete the six links in the chain of transmission for mrsa.
2. explain at least three ways that links in the chain of transmission may be broken to stop the spread of the infection.

Hey! Let's break it all down!

Methicillin: It is an antibiotic formerly used in the treatment of bacterial infections caused by genus Staphylococcus. It's a semisynthetic derivative of penicillin. It contains a modification to the original penicillin structure that makes it resistant to an enzyme called penicillinase.

Resistant: Pertaining to the ability of a microorganism to remain unaffected by and antimicrobial agent. Or a lack of response to, or of influence by, a pathogen, toxin, treatment, or other stressors.

Staphylococcus aureus: Well, it is a type of bacteria. It is apart of the Staphylococcaceae family. It is a very bad bacteria to have as it can cause infections.

2. Alright. Let's see if this is correct.

1st Link: Infectious Agent. 
2nd Link: Reservoir. 
3rd Link: Portal of Exit. 
4th Link: Route of Transmission. (Can only be spread through direct contact with infected material.)
5th Link: Portal of Entry. (Enters the body through open wounds, sores and such.)
6th Link: Susceptible Host

Signs and symptoms of MRSA could be:

Minor skin infections.
Boils, Cellulitis Folliculitis, Carbuncles.
Scalded Skin Syndrome and Abscesses.
Lung Infection or Pneumonia.
Brain Infection or Meningitis.
Bone Infection or Osteomyelitis.
Heart Infection or Endocarditis.
Life threatening blood infections or TSS (Toxic Shock Syndrome.)

Finally, the first way to break the chain of transmission is to simply block out the route of transmission, since this bacteria can only be spread through direct contact with infected material, doing things such as washing hands regularly, cleaning and covering wounds, taking antibiotics if they are prescribed can help break that chain of transmission.

Another way is to not come in contact with direct contact to people who do have it. This may sound obvious, however the MRSA bacteria would eventually leave the host through open sores or wounds. Meaning it is probably the best to stay away from them, so it doesn't transmit to you or others.

Last but not least. You can block its Portal of Entry. By quickly taking care of any type of injuries on your body and with the right treatment, you can quickly block off the Portal of Entry before it can be transmitted to you.

Have a nice day!
