Is it possible to cure gut worms in Rimworld

Select a colonist and right-click on the comms console; there should only be one option, "open communications". Select it. They will walk over to the console and start fiddling with it, at which point a window will pop up asking which ship to open communication with. If there are no ships in range, they'll still try to use the console but that window will instead say "there is no-one in range to communicate with".

If the "open communications" option doesn't appear or the colonist refuses to use the comms console, check:

• That the console has power.
• That the colonist can reach it; some pieces of furniture, like potted plants, block pathing.
• That the colonist is capable of social interaction. (To check, select the colonist, click "Character" in the lower left, and look at the "Incapable Of" section to see if it includes the word "social".)

If all of these requirements are met and you still can't communicate, you've probably hit a bug; Rimworld, being pre-alpha, has these in abundance.

Rescue: Left click a healthy colonist to select them. Right-click the sick or injured colonist to open the context menu. Left click "Rescue [name], [title]" to order the colonist to rescue them. You will need an empty bed or sleeping spot that you've marked for hospital use for this to work, otherwise the colonist won't know where to take the patient.

Eat where you want them to: How far a colonist will look for a table and chair to sit and have their meal depends on how hungry they are. If they're just kinda hungry they'll walk with their meal a decent distance to find a good place to eat. If they're taking starvation damage they'll carry whatever food they find a few steps max before they start devouring it. I suggest making a small, high-priority food stockpile near the table you want them to use, or just storing ALL your food in a freezer near it.

Sleep where you want them to: Build a bed (or sleeping spot), click the bed to select it, at the bottom of the screen click "Set owner", choose the colonist you want to sleep in that bed. Note that no matter how tired they are or how far from bed they are, they will walk all the way back every time they go to sleep, so if you have them doing work a long way from home for a while, you might want to change their owned bed to one nearer the work.

General navigation stuff:

• It's a little counter-intuitive, but to have colonists interact with things that are constructed, you usually pick the thing first and use one of its menu options to interact with the colonist (like the bed example above, or setting a "bill" for item production in a workshop).
• To have a colonist interact with a piece of equipment, another colonist, or a visitor, you select the colonist and then right-click on the the thing/person you want them to interact with (like the rescue example, or for equipping gear).
• To have a colonist interact with the environment, you usually use the "Orders" tab in the architect.
• To have a colonist interact violently with something or someone (besides hunting, that's "Orders"), you pick the colonist, draft them using their menu, and then can use right-click to move them to specific locations (they will fire around corners, using them as cover) or order them to attack specific targets.
