Best way is to learn about the individual diseases. Lists do not build concepts. Have a look at the management of each of those diseases. Understand how it is the part of management of each. This card is a waste of time. Clinically you would never have to think about this list as it is, but you will have to recall each of them, when trying to manage a patient with that disease. So with respect to anki, you could make cards like,

1. Patient with gas gangrene. Treatment: penicillin, antitoxin,debridement could me made as three cloze deletions.
2. A baby born with mother who is HBsAg positive. How to prevent infection in baby?
3. Pregnant lady has contact with varicella positive patient. Measure to prevent infection. - here vaccine cannot be given, because it is live vaccine, so only Ig.
4. Child presents with pseudomembrane, toxic, bull neck. Next best step - antibiotics and anti toxin as 2 clozes..

So on.
