In Anno 117, this situation usually starts the same way: a warning pops up saying people are sick in the wetlands, so the natural reaction is to grab a medic and try to drop it right on the problem area.
Then the game simply refuses to allow placement. The medic icon stays blocked, there’s no clear tooltip explaining why, and the research tree doesn’t point to an obvious solution.
That’s when it feels like the game is either bugged or quietly telling you to accept population loss.
This moment is exactly why many players end up searching for things like “Anno 117 medic not working”, “cannot place medic in wetlands”, or “wetlands sickness Anno 117”.
The frustration comes from the fact that the sickness system works differently in wetlands than on normal land tiles, but the game doesn’t clearly surface that distinction when the alert appears.
Clear answer
In Anno 117, wetlands are treated as restricted terrain, which means medics cannot be placed directly on wetland tiles, even when the game reports sickness there.
Instead of direct placement, wetlands sickness is handled through medical coverage mechanics. Treatment comes from nearby medical buildings whose service range reaches the wetlands, dispatched or mobile medical services, or wetland-specific medical options unlocked through research.
Once proper coverage is in place, the sickness resolves automatically without placing a medic on the wetland itself.

Why medics cannot be placed in wetlands
This restriction usually comes down to how Anno 117 treats wetlands compared to normal land. Even though people can live or work there, the game doesn’t consider wetlands a valid surface for dropping service units. So when players try to place a medic and see the option blocked, it feels broken—but it’s actually a rule of the terrain.
First, wetlands are flagged as non-buildable tiles for service units like medics. The game allows sickness to occur there, but it does not allow direct placement on the tile itself. That design choice is what triggers searches like “cannot place medic in wetlands Anno 117”.
Second, medics are not fully independent units. They usually need a parent medical building, such as a clinic or medical hub, to operate. Instead of being dropped anywhere, medics function as part of a wider healthcare system that projects coverage outward from those buildings. This is why players often think the Anno 117 medic is not working, when in reality it just isn’t being deployed correctly.
Third, medical services work on area-based coverage, not tile-by-tile placement. If a wetland tile is inside the service range of a medical structure, it can be treated—even though no medic ever appears on the wetland itself. If that coverage doesn’t reach far enough, the sickness warning stays active.
In some cases, the limitation is also tied to missing research. Certain medical upgrades or wetland-specific technologies must be unlocked before healthcare can reach these biomes effectively. Until then, treatment options remain limited.
Finally, tile control matters. If the wetland lies outside the player’s controlled territory, medical services will not apply at all. This often explains why sickness persists even after nearby medical buildings are constructed.
Together, these mechanics are why searches like “Anno 117 medic not working” and “wetlands sickness Anno 117 fix” are so common—the system is working as designed, but the rules are easy to miss when the alert first appears.
How to treat sickness in wetlands (solutions)
1. Build a medical structure nearby
The first thing to do is stop trying to place a medic directly in the wetlands. Instead, drop a clinic, field hospital, or medical hub on the closest buildable tile next to the wetlands. In Anno 117, medical buildings don’t just serve the tile they sit on — they push healthcare coverage outward, and that coverage is what treats sick populations in wetlands.
2. Make sure the coverage actually reaches the wetlands
A nearby building isn’t enough on its own. The medical structure needs to be properly connected. Check that it has:
- Road or path access
- Any required service or utility connections
- The correct regional supply links, if applicable
Then turn on the coverage overlay. If the wetlands tile isn’t highlighted, the sickness will not resolve, even though a medical building is close by.
3. Use dispatched or mobile medical services when available
Some healthcare systems in Anno 117 don’t use direct placement at all. Instead, medics are dispatched through menus or triggered by interacting with the sick population. Open the health, population, or settlement interface and look for a request or dispatch option. This often treats wetlands sickness without placing anything on the map.
4. Check the research tree before assuming it’s blocked
If none of the options seem to work, the issue is often locked research. Certain medical upgrades or wetland-specific technologies are required before healthcare can properly reach restricted biomes. Until those are unlocked, the game quietly limits what medical services can do in wetlands.
5. Confirm the wetlands tile is under your control
Medical services will not operate on unclaimed or uncontrolled tiles. Even with perfect coverage and research, sickness will persist if the wetlands are outside your territory. Claim or secure the tile first, then recheck coverage.
When these steps are followed in order, wetlands sickness in Anno 117 resolves automatically, even though no medic is ever placed directly on the wetland tile.
Quick tips
- Always check the build tooltip first. If the medic icon is blocked, the tooltip usually confirms that wetlands are not a valid placement zone. This saves time when troubleshooting Anno 117 medic placement issues.
- Think in terms of coverage, not placement. In wetlands, sickness is treated when a medical building’s service range reaches the tile. Trying to place a medic directly in the wetlands will never work.
- Use one medical hub efficiently. A single clinic or medical hub can cover multiple wetland tiles if positioned correctly, making it more effective than attempting multiple placements.
- Prioritize medical research in wetland-heavy regions. Unlocking medical upgrades and wetland-related technologies early prevents situations where wetlands sickness in Anno 117 cannot be treated.
- Reload if coverage looks wrong. If the coverage overlay does not update after building or connecting services, reloading the save often refreshes the visual state and confirms whether treatment is active.
Common causes and fixes (comparison table)
| Issue observed | Likely cause | Correct action |
|---|---|---|
| Medic placement blocked | Wetlands are non-buildable | Build nearby medical structure |
| Sickness not resolving | No service coverage | Add roads or service links |
| Medic option unavailable | Research not unlocked | Complete medical research |
| No treatment applied | Tile not owned | Claim the wetland tile |
| UI appears inconsistent | Overlay not refreshed | Reload and recheck coverage |
Is this a bug?
In most cases, no.
This is a designed terrain and service limitation. It should only be considered a bug if:
- Coverage overlays confirm service but sickness persists
- Placement rules contradict in-game tooltips
- The issue reproduces consistently across multiple saves
Summary
In Anno 117, medics cannot be placed directly in wetlands due to terrain restrictions; sickness must be resolved by extending medical coverage from nearby structures, unlocking appropriate research, or using dispatched medical services, making this a rule-based mechanic rather than a placement error.
