This is the way it appears in the V1 Refs book:

Dysentery

Transmission: Contaminated food and/or water. Infection

Number 60.

Symptoms: Abdominal pain, diarrhea.

Diagnosis: AVG

Misdiagnosed as: Cholera, or minor disease.

Treatment: Replace fluids ( + 30%), relieve pain (+ 10%).

Course of the Disease: Incubation: 1 -3 days (1D6/2). Phase I:

3 days. Phase II: 7 days. Base Recovery Number: 195.

Failed Recovery Death Probability: 5%

Post-recovery Debility: 7 days. With treatment, fatigue at level

1 base; without, level 2

I believe the problem here is formatting. It should read as follows:

Dysentery

Transmission: Contaminated food and/or water.
Infection Number 60.
Symptoms: Abdominal pain, diarrhea.
Diagnosis: AVG
Misdiagnosed as: Cholera, or minor disease.
Treatment: Replace fluids ( + 30%), relieve pain (+ 10%).
Course of the Disease: Incubation: 1 -3 days (1D6/2). Phase I: 3 days. Phase II: 7 days.
Base Recovery Number: 195.
Failed Recovery Death Probability: 5%
Post-recovery Debility: 7 days.
With treatment, fatigue at level 1 base; without, level 2

Note the last line re fatigue is separate to post recovery debility, and should apply from the moment Phase 1 begins, and will continue until the Post-recovery Debility period has expired.
This is on top of any symptoms which would impair the character while suffering the illness - Abdominal pain & diarrhea in the example above are going to make it very difficult to carry out some tasks. Vomiting may invoke the starvation rules, and so on.

Yes, getting sick can be quite nasty if you look at this way, but these diseases have killed many people over the centuries, they are nasty.
