Circumstances of outbreak. 
In 1 week 15 cases were reported 
among consumers of milk 
from 1 dairy. Houses scat- 
tered, children attended dif- 
ferent schools, several adults 
were attacked. Klebs-Lof- 
ller bacilli found in culture 
from throat of child on dairy 
farm, and also in all cases on 
milk route. 
At beginning of epidemic most 
of the cases were in families 
using milk from a dairy where 
there was found a case of 
diphtheria in a boy walking 
about. A large per cent of 
the families using this milk 
were affected. 
Milk supply of only 50 of the 
cases could be ascertained; of 
these, 47 were supplied from 
a common source. 
Explosive outbreak. Cases 
widely scattered, but all tak- 
ing milk from 1 dairy. 
Most of the invaded houses 
wore supplied with milk from 
1 farm. Between 13 and 15 
percent of houses so supplied 
were invaded, whereas only 
1.3 per cent of other houses 
were affected.
