What is needed if a hepatitis B positive mother gives birth to a baby?
Vaccination ± IV immunoglobulin within 24 hours.
Give 6 ways as to how HCPs can act to prevent the spread of childhood infection.
1) Isolation (e.g. on the ward)
2) Hand washing
3) PPE
4) Chemoprophylaxis

1) What is meningitis?
2) Name 3 viral infections that can cause meningitis.
3) What proportion of cases of meningitis are caused by viruses?
4) Generally, how is viral meningitis treated?
1) Inflammation of the meninges which cover the brain and spinal cord.
2) enterovirus, EBV, adenovirus and mumps.
3) 2/3rds.
4) Viral meningitis is often self-resolving.
Give 6 ways in which viral meningitis may be diagnosed.
1) CSF culture/ PCR
2) Stool
3) Urine
4) Nasopharyngeal aspirate
5) Throat swabs

2) 80%
3) In winter
1) Briefly describe the distribution of meningitis infections across the population.
2) What is the mortality rate in patients with meningitis?

2) 5-10%
Give the 3 main causes of bacterial meningitis in the neonatal to 3 month old period.
Group B streptococcus
E. coli and other coliforms
Listeria monocytogenes
Give the 3 main causes of bacterial meningitis in the 1 month to 6 year period.
N. Meningitides
S. Pneumoniae
H. Influenzar
Give the 2 main causes of bacterial meningitis in children >6 years old.
N. Meningitides
S. Pneumoniae
1) Who must you notify if you suspect a patient may have meningitis?
2) If a person is diagnosed with meningitis, who should you trace?
1) Public health
2) Close contacts with the last 7 days prior to symptom onset.
Who is classified as being a close contact of a person if they are diagnosed with meningitis?
- People in the patient’s household
- People the patient has shared a room with
- People who the patient has eaten with
- Partner of intimate kissing
- Healthcare workers exposed to droplet secretions
1) What should close contacts of a patient with meningitis be offered?
2) What is the aim of treating close contacts?
1) Antibiotics (Rifampicin/ Ciprofloxacin)
2) The aim is to decrease nasopharyngeal carriage of the strain and to decrease risk for others.
What is a communicable disease?
An illness due to an agent or its toxic product which arises through transmission from an infected person, animal, or reservoir to a susceptible host.
List the 5 stages in the chain of infection.
1) Infectious agent
2) reservoir/ environment
3) Mode of transmission
4) Portal of entry
5) Host
State the characteristics of an infectious agent or pathogen.
a. Ability to reproduce
b. Survival (including environmental)
c. Ability to spread
d. Infectivity (ability to cause infection, also consider colonisation without infection)
e. Pathogenicity (severity of the illness)
1) What is infectivity?
2) What is colonisation?
3) What is pathogenicity?
1) The capacity to enter, survive and multiply in a host.
2) Infection but no immunological response
3) Capacity to cause disease.
Name 4 types of host.
Humans
Animals
Water systems
Environmental contamination
Name 4 different modes of transmission of disease.
1) Respiratory
2) Ingestion
3) Blood borne
4) Sexual contact
Name 5 portals of entry for infections in humans.
1) Mouth
2) Nose
3) Ears
4) Genital tract
5) Skin (barrier breakdown)
Name 5 host factors that can affect the speed of spread of infections.
1) Chronic illness
2) Nutrition
3) Age (the very young and the very old)
4) Immunity (immune condition, chemotherapy, transplant)
5) Lifestyle factors (drugs, alcohol abuse, SES, occupation)
Give the 2 main types of direct transmission.
1) Immediate transfer (contact, droplet)
2) Vertical transmission (HIV, syphillis, Hep B)
Give the 3 main types of indirect transmission
1) Airborne (aerosol, droplet)
2) Vector-borne (mechanical/ biological)
3) Vehicle-borne (water, food, blood, organs)
What is surveillance?
“Systemic collection, collation and analysis of data and dissemination of the results so that appropriate control measures can be taken”
