/diseases/{disease_code}/distribution/{country_code}/associated-infections

Returns **survey-style rows** that highlight **co-infections and related conditions** captured in prevalence/seroprevalence work for **HIV in the selected country**. **Important:** The API only attaches rows for **GIDEON disease id `10040` (HIV)**. For **any other** `disease_code`, the response is **`{ "data": [] }`** with **200** and no further validation of the country code. For **`10040`**, each item is ordered by the latest survey or publication year and includes geography (**`region`**, **`state`**, **`city`**, coordinates), the surveyed **`population`** label, percentage fields, free-text **`notes`** (HTML with GIDEON tags), resolved **`references`**, **`survey_type`** (`prevalence` or `seroprevalence`), the linked **`disease`** label being measured, and expanded lists **`organism_entities`**, **`pathogens`**, **`test_types`**, and **`review_types`** (each may be empty). #### **Path parameters** | Name | Description | | --- | --- | | `disease_code` | GIDEON disease id. Only **`10040`** yields rows. | | `country_code` | GIDEON country code (used when `disease_code` is **`10040`**). | #### **Query parameters** None. #### **Errors** | HTTP status | When | | --- | --- | | **400** | Server-side lookup failure — `{ "message": "Invalid disease_id or country_code." }`. |
