infection Flashcards
what are the phases of acute infection
- Incubation - infected, but the pathogens are low. No S+S have developed
- prodrome - initiated of S+S (Mild and vague), pathogen continue to replicate
- Ilness - period of significant S+S
- decline- decline of s+s as elimination of pathogens enhances
- resolution - S+S disappear, infection has been eliminated
Signs and symptoms of infection
fatigue
general unwell feeling
weakness
loss on concentration
reduced appetite
aches
localised symptoms (redness, swelling, pain, heat and puss
what is contact transmission
Direct transmission - direct contact with the pathogen (touching genital warts)
indirect transmission - coming into contact with contaminated surfaces containing the pathogen
PPE= gloves and gowns
what is droplet transmission
example fluid and COVID
coming into contact with the pathogen 1-2meters
PPE= surgical mask + goggles
airborne transmission
example= tuberculosis, chicken pox
float through the air
move the patient into the room with negative pressure
PPE= N95 mask
Complex transmission
A disease that is spread by more than one method. eg chickenpox can be transmitted by droplets but in serious cases, airborne can occur
Bacterial infection
Group A strep throat.
transmission= droplet, direct contact with skin sores
acute infection= strep throat
complications = rheumatic fever may develop. when your body starts attacking your cells that look like bacteria protein. brain, joints, heart and skin
viral infections
influenza viruses
transmission= droplet, direct contact with infected respiratory secretions
infection = affects the upper respiratory tract lining, initiating inflammatory responce
treatment = vaccines help, hand washing
fungal infection
transmission= direct and indirect
opportunistic infection = something that generally wouldn’t cause a disease but gets the chance to because the immune system becomes weak, or something else happens that upsets the natural balance.
candidasis= fungus that colonises the human respiratory tract, GI tract or vagina
treatment = cream (miconazole) or an antifungal (nystatin. which has to be applied to the skin)
sepsis
The entire body’s inflammation reaction. The immune system overreacts and starts to damage tissues.
who is most at risk of sepsis
People who are at higher risk of developing and infection (old people, infants, people with chronic diseases)
people who can not control an infection (decreased immune system)
people in hosptial, using IV needles, women who are pregnant
signs and symptoms of sepsis (changes in vital signs)
fever
tachycardia (increased heart rate)
tachypnea (Increased breathing)
decrease in oxygen saturation
hypertension
what does testing and treating look like for sepsis
the sepsis six - should be implemented within 1 hour of suspension of sepsis
- blood cultures
- lactate labs
- antibiotics
- iv fluids
- supplement oxygen if needed
