index case

There is one thing about the two index cases that I find curious.

I even have the vaccination gun used to infect the index cases.

At the time of diagnosis, 217 of the present 240 index cases had spouses.

The trick, then, if you wanted to create a much wider outbreak, was to increase the number of index cases.

The index case is the first patient that indicates the existence of an outbreak.

The index case, a mare, was housed with 19 other horses after falling ill, and died two days later.

"All the index cases from these recent outbreaks have had some sort of chronic illness," jack said.

Seeing such a profusion of items made him wonder if there had been anything unique sent from central supply to the index cases.

The list was just as long as the lists he had for the infectious disease index cases.

If this is an outbreak of some sort, maybe we can isolate the index case.
