Front 1

STREPTOCOCCUS PYOGENOMES (STREP THROAT)

Back 1

1. Airborne
2. High fever, coughing, swollen lymph nodes and tonsils
3. Antibiotics
4. Everyone
5. Turns into scarlet fever bright red cheeks and “flesh eating” necrotizing fascitis

Front 2

Front 3

DIPTHERIA

Back 3

1. Airborne- inhaled through respiratory droplets
2. Sore throat, painful swallowing, difficulty breathing, suffocation

4. 5-10% death in children
5. “Strangling Angel of Children” disease

Front 4

PERTUSSIS (WHOOPING COUGH)

Back 4

1. Airborne
2. Mucus and cell debris accumulate, labored breathing, cough- nails and lips turn blue

Front 5

BACTERIAL MENINGTIS

Back 5

1. Airborne

Front 6

TUBERCULOSIS (MYCOBACTERIUM TUBERCULOSIS)

Back 6

1. Airborne- inhaled through respiratory droplets
2. Symptoms not noticeable until disease has advanced  loss of weight, no energy, poor appetite, fever, a productive cough

Front 8

THE PLAGUE –“BLACK DEATH”

Back 8

1. Anthropodborne
2. Enlarged lymph nodes, black fingerscarried by fleas and passed on to rodents which is passed on to humans once humans get it, it can be passed on by respiratory droplets from human to human
