Infectious Diseases Protect Flashcards
What did Semmelweis do?
He advised for hospitals to wash hands with soap to prevent infectious diseases
What happens when you overuse antibiotics
The pathogens will mutate and become immune to the antibiotics as they become used to the drug
Consequences of bacteria in relation to epidemic and pandemic
Immune to medication (mrsa) lead to increased spread of diseases as medication cannot fight off.
Epidemic: disease in community
Pandemic: disease country or world wide
Advantages and disadvantages for vaccinations
Can stop widespread diseases
People are immune
Save lives
Allergic reaction
What do bacteria and viruses produce and what does viruses do
Toxins and viruses damage cell wall by reproducing
How does white blood cells protect against pathogens
Ingest pathogens
Antibodies produced to destroy bacteria or virus
Antitoxins counter act toxins
Immune system
Immune system produce specific antibodies for pathogens
Dead or inactive pathogens stimulate antibodies production
Reduced when population immune
What do painkillers do
Relieve sunrooms of disease but don’t kill pathogens
Antibiotics
Cure diseases by killing bacteria inside body
Cannot be used to kill viral pathogens as inside self cells
The use of antibiotics has reduced deaths from diseases
Overuse and inappropriate use can cause antibiotic resistant strains on bacteria
Mrsa
Resistant bacteria to antibiotic as a result of natural selection
Mutations of pathogens
Antibiotics and vaccine no longer effective against new stain of pathogens
Spread rapidly as people aren’t immune
No effective treatment
Vaccination
Small quantities of dead/inactive pathogens
Stimulate white blood cell production of antibodies
Makes immune to further infections by the microorganism
Body responds rapidly by making the correct antibody as if had the real disease
MMR
Measles mumps and rubella vaccine
Temp of pathogens to reduce growth
25*c
