Probability of dying before the age of 1
Are stillbirths / miscarriages included in infant mortality rates?
No, live births only
Countries where the infant mortality rate is high tend to have less ___.
doctors
What parts of the world have the highest infant mortality rates?
Africa
SE Asia
Neonatal mortality describes the death of a child in what period of life?
First 28 days
What simple measures taken at birth reduce the infant mortality rate?
Skilled attendant > clean deliver
Vaccination
Treatment for infection
What is the most common respiratory cause of infant mortality?
Pneumonia

Diarrhoea
secondary to gastroenteritis caused by contaminated water and food
How can pneumonia be prevented?
Vaccination
Good hygiene
Nutrition support

Why is compliance for anti-retrovirals poor?
Disgusting medication
How does HIV cause immune suppression?
Attacks CD4+ T cells, inhibiting body’s ability to produce an immune response
What distinctive tumour(s) are associated with HIV infection?
Kaposi sarcomas
Which type of pneumonia is associated with HIV?
Pneumocystis jirovecci
What sort of vaccines should be avoided in people with HIV?
