What is the continual struggle with infectious disease?
keeping antibiotics ahead of mutations
antibiotics in the 1950s-1980s: These drugs helped limit damage from bacterial infections
- sulfa drugs
- penicillins
- antibiotics
examples of immunizations
- measles
- mumps
- rubella
- poliomyelitis
What are some of the new infectious agents brought about in the 1970s and 1980s?
- legionella
- HIV
- antibiotic-resistant organisms

- ebola

- C-diff
What are some of the s/s of infectious disease?
- abscess
- skin lesions
- joint effusion
- inflamed lymph nodes
- red streaks
What do red streaks indicate?
blood poisoning
What is the 102˚F rule?
conditions in which fever does or does not exceed 102
102˚F rule:
Some people with serious infections may not develop an initial fever, but may have these s/s:
- tachypnea
- confusion
- hypotensive
What is tachypnea?
SOB
What should you do if a pt is hypotensive?
assess to see if it’s positional or not
102˚F and aging adults
- impaired thermoregulatory system may mask fever
- temp of 99-100 may be sufficient to cause alarm
How does an abscess form?
- leukocytes wall off invader and form granuloma
- necrosis progresses
- abscess deepens
How does an internal abscess present?
- pain
- limp
- lump
Types of internal abscesses
- abdominal abscess
- pelvic inflammatory disease
- TB of the spine
abscess with TB of the spin
location and presentation
- between posterior peritoneum and psoas/iliac fascia
- presents as hip pain
Skin lesions that may occur with infectious disease
- rash
- macropapular eruptions
- vesiculobulbous eruptions
- petechial or purpuric eruptions
macropapular eruptions (associated dz)
measles, mumps
vesiculobulbous eruptions (associated dz)
herpes zoster
petechial or purpuric eruptions (associated dz)
Epstein-Barr
