Pathogens are microorganisms capable of causing disease in humans.
Bloodborne pathogens circulate in the blood and can be transmitted through exposure to blood and OPIM.
MRSA is hard to cure because it is often resistant to many other antibiotics besides Methicillin.
Syphilis is spread by contact with syphilis sores and rashes.
The secondary stage of syphilis starts when the initial chancre or sore disappears and heals without treatment.
