Guide to Virology

As a virologist you are responsible for curing all ailments that befall the station as well as the synthesise of new pathogens to help the station crew. This guide overviews the process to conduct virology in Unitystation.

Disease Basics / Health & Safety

Diseases in Unitystation function similarly to reagents (chemicals). Any place that can contain a chemical (such as a syringe, beaker, food, etc) can contain diseases. While diseases can exist in any reagent container, they will only grow when metabolised by a host body.

Creatures (including crew members) become sick when a pathogen enters their bloodstream. The concentration of the pathogen in the blood stream controls not only the rate of growth, but the exhibited symptoms too. Diseases often start harmless or with simple emotes that spread the disease (such as coughing and sneezing) but can quickly evolve to be dangerous if not attended too soon enough.

Every creature also has an immune response. A creature's immune response counteracts the growth of a pathogen; it is most effective when the pathogen is in small amounts but often gets overpowered if a disease is sufficiently present. A creature's immune response can be varied by mutations*.

Medical HUDs will show the most prevalent disease (That with the highest stage) a player is infected by with an emoticon to its left. The sadder the face, the further the disease is progressed. No emoticon indicates the patient is healthy.

*Immune mutations are planned but not currently implemented. This note will be removed once these mutations are added.

Many sicknesses once they have developed far enough, will begin to induce symptoms that cause the disease to spread (Such as coughing and sneezing). Crewmates in the area of affliction can catch these sicknesses and begin to spread the disease themselves.

There are several methods to prevent such events:

- Wearing a sterile mask or another protective helmet (such as a biosuit helmet) will prevent infection from coughing & sneezing

- A sick patient wearing a sterile mask or another protective helmet will be unable to spread diseases via coughing & sneezing

- Wearing enabled internals will also prevent infection from coughing and sneezing.

- Wearing a full biosuit will prevent infection from methods that involve splashing, such as the ever-potent plague bomb.

Virology Equipment

Sequence Analyzer

The sequence analyzer is the first machine on the step to curing a disease. It analyzes a provided blood sample to identify a present disease and propose possible cures. It requires a connection to power.

Cure Tester

The cure tester is an accelerated way of testing the effectives of a possible cure. It requires both a connection to power and a sequence analyzer. The cure tester will test the contents of a provided beaker against the most recent disease analyzed by the sequence analyzer. It will provide 3 different messages based on the effectiveness of the cure

Treating Patients / Curing Sicknesses

Treating sicknesses is a fairly straight forward process, although it can be difficult and time consuming. A cure for a given sickness is randomised on round start, but a cure for any one patient, will work on all others with the same sickness. A step-by-step method for curing a patient is found below.

1) Once a patient is believed to be sick, take a blood sample using a syringe in 'DRAW' mode. Place this blood sample into a petri dish for further testing.

2) Place the petri dish with the blood sample into a sequence analyzer by pressing on the empty slot while holding the dish. Once the dish is inserted, press the analyzers 'test' button to test the blood sample. The sequence analyzer will report wether or not it found any disease in the blood sample. For each disease found, it will provide a list of 5+ chemical reagents. From these reagents, a combination of 2 of them will form the cure for that sickness, another 2 will be 'inhibitors'. If both cure reagents are present with the pathogen, but none of the inhibitors, the pathogen will be killed by the cure and the sickness treated. The analyzer will also report it's "active disease". This is the disease that will be used by the cure tester to determine the effectiveness of a given cure.

3) Mix up a series of possible cures based on the clues from the sequence analyzer. Place each possible cure into the beaker slot of the cure tester and press the 'test' button. When testing a cure, the cure tester will produce one of 3 outputs.

An alternative way to think of the response is as such:

Response Number = Number of Cure Reagents in Mix - Number of Inhibitors Reagents in Mix

Response No.	Response Text	Explanation
0	No change in the pathogen was observed	Either no cure reagents were present, or the number of inhibitors outweighed the number of cure reagents
1	The pathogen showed signs of weakening, but remained prevalent	Either one of the two cure reagents were present, or both and a single inhibitor
2	The pathogen was severely degraded by the chemical mix	Both cure reagents were present and no inhibitors. This chemical mix contains the cure for the specified pathogen

4) Once you have found the cure from step 3, distribute the cure in a desired form to infected crew mates (Pills, drinks, food, etc). For every 2 units of cure (1 part of each cure reagent), 5 units of pathogen will be killed. Cures are metabolised by the body at the standard rate and will stay in the body until filtered out by the body's organs. Because of this, patients who are very sick might take time to get better, additionally, players can be 'vaccinated' from a disease by pre-emptively taking a cure. As the cure will stay in the blood for a period of time, it will kill the target sickness instantly when it tries to afflict the target.

5) Cures will stop diseases from progressing and prevent further symptoms, however, damage from diseases will not disappear with the disease. Instead, remnant toxic damage, genetic damage, etc might require manual healing based on the severity. If several disease require treatment, consider offloading this treatment process to the station medical doctors.
