So you want to be a Virologist, creator of a beneficial virus? Or just want to cure viruses that plague the station? Then this is the guide for you! Here you will learn how to make viruses and how to cure them.


Virology is sealed from the rest of the station. You are not on the disposals network, nor do you share the same atmos system]]

Virology 101

If you are a Virologist for the first time, read this part very carefully!


Every virus behaves differently, from created viruses to event spawned viruses. Most viruses can spread themselves to other humanoids near the host in one way or another. These types of spread are:

  • Airborne - The most dangerous and quick spreading, if you are anywhere within the breathing area of the infected crew member, you have a chance to be infected. Wearing internals stops further infections.
  • Direct Contact - Requires you to touch, been touched, or be extremely close to the source of the infection. The infection will be spread by the skin and bodily fluids of an infected person, but will not survive long in the air. Wearing protective clothing and avoiding infected are great ways of not getting infected yourself.
  • Blood - The infection will be spread by blood from the infected person. Beneficial viruses usually fall under this category.
  • Special - The disease is not normally contagious and the affected crewman has been infected by a non-human vector source. You can work with the infected without risk yourself unless they expose you to the same vector source that infected them.

All viruses that spread with blood or above mentioned transfer by giving humanoids an infected blood sample using either a syringe, a pill or other types of food/drinks or by using the virologists agent item Viral Injector. Smoke grenades or syringe guns will not work. Every virus or vaccine only requires any amount of units to infect or cure somebody, 0.1 unit will work.

Each virus will not be visible on the Medical HUD till they reach a later stage, meaning at least at the halfway point of the stages (rounded up). For example, the Brainrot virus has 4 stages. The virus will then be visible starting at the 2nd stage. Any advanced virus has 5 stages total and it can be visible on the HUD starting at the 3rd stage depending on the stealth stat (see Advanced Diseases for more information).

Each virus also has their own chemical(s) that the infected needs to ingest for them to be cured. See Infection Listings for the cures for the known viruses. The virus has a chance to be cured once the infected humanoid has the chemical(s) in their body. Once the victim is cured, they will be immune for that virus till they get cloned or put in another body. A good idea is to get a blood sample of the person you cured to make a vaccine. See Curing A Virus for more details.


The following items will be used during researching:

  • Beaker.png Beaker (to mix viruses and store diseases and chemicals)
  • Dropper.png Dropper or Pipette (to carefully measure the units, right click on the dropper to set the transfer amount)
  • Pen.png Pen (to label your beakers)
  • Virus sample.png Flu or Rhinovirus Culture Bottle (to start your virus, found in your Smartfridge)
  • Biobag.png Biobag (For storing your virus samples and beakers)


Should a virus start spreading on the station (or should you work on something nasty and use the monkeys for it), you have to keep your workplace sterile and yourself safe. For this, you will find these useful:

  • Biohood virology.png Level-3 Bio Hood (against On-Contact viruses)
  • Biosuit virology.png Level-3 Bio Suit (against On-Contact viruses)
  • Gas mask.png Internals (against Airborne viruses)
  • LGloves.png Latex Gloves (against On-Contact viruses)
  • Sterilemask.png Sterile mask

This is your best friend while you do your job. Not only can this bad boy tell you what is in a blood sample. It can also duplicate any virus in that sample for further research. You can do the following with the machine

  • See the statistics of a virus that is put into the machine.
  • Make a new virus culture for later use (Use this when making advanced viruses)
  • Make vaccines using blood from a patient that was cured from a virus prior.
  • Name an advanced virus if it is not named yet
  • Print a release form for named viruses

Curing A Virus

So you are tasked with curing a virus that is harming the station's inhabitants? Well you are just a few steps away from being the unsung hero!

Curing The First Infected

First priority is finding the crewmember who is infected and getting them to medbay into isolation as fast as possible. It is easier to cure a singular person compared to curing a whole station. A virus will not show up on the Medical HUD when the virus is in its early stages. You will need to use the Health Analyzer to find viruses still in their early stages. Once you have the infected you will want to get the cure in them as soon as possible. Once they're cured, you will have to take a blood sample for the next step.

Getting The Vaccine

Once you have the blood of a cured subject you can start mass producing the cure. To do this you will need the PanD.E.M.I.C 2200.

  1. Put the blood in the PanD.E.M.I.C 2200. A syringe can be put into the machine
  2. Click on the create vaccine button next to the virus you want to make the vaccine for. If the blood contains multiple antibodies to different viruses you will have more than one option.
  3. Repeat till you have enough vaccine.
  4. Bring the bottles to the Chemists so they can pill the vaccine into pills. Make sure that they call it a suiting name else it might get lost in a pile of pills without people knowing what it actually cures.

A vaccine is spread just like a virus. So you can just take a sip from the bottle to cure yourself.

Spreading The Vaccine

Curing the infected will be easy once you have the vaccine. A single dose of, for example, 0.1 units will cure anybody and will make non-infected immune to the virus. However, the dosage amount does not matter, so you can use more or less than 0.1 units if you wish to. Be sure to get everybody cured otherwise bad things can happen.

Infection Listings

Thankfully, humanity has managed to cure and eliminate almost all of the diseases that plagued its infancy. However, the vast reaches of space have been found to harbor new illnesses that can affect the unprepared staff on Nanotrasen research stations.

Disease Name Agent Name Description Spread Cure Event

Creating A Virus

You will be spending most of your time doing this part. Either for good or for worse.

Advanced Diseases

An advanced virus works a bit different compared to a "normal" virus. The most significant differences are.

  • You can only have one advanced virus per person
  • You can mutate advanced viruses using chemicals
  • You can combine advanced viruses

An advanced virus can have up to 6 symptoms. You do this by mixing two virus samples. By the powers of RNG, you can get the desired outcome.
A virus has statistics that all symptoms will influence, and some symptoms will be more effective with certain stats. Every symptom has these stats which have the following effect.

  • Stealth, if the virus is visible to scanners or other devices
  • Resistance, how hard it is to cure the virus
  • Stage Speed, how fast the virus will reach its final stage making it act faster
  • Transmittable, what the virus uses to spread to other victims
  • Level, this is the level of the symptom. You will need different chemicals to generate symptoms with different levels. For example, the "Toxic Filter" symptom requires a chemical capable of generating level 6 symptoms.

Every symptom added will influence the statistics of the virus. Having more symptoms will lower the Transmittable and Resistance statistic. Thus having more symptoms is not always better in some cases. See Understanding Stats for more info.

Engineering The Perfect Virus

So you think you are ready to make a virus that can benefit the crew? Before you start ensure that you have thought of a set of symptoms you want the virus to have. Once you have the symptoms you can begin. The general method to get a symptom goes as follows.

  1. Get a virus sample in a beaker. Use the Dropper or pipette for this.
  2. Add 1 unit of the chemical you need for the symptom to the beaker. This makes the virus mutate a new random symptom.
  3. Put the sample in the PanD.E.M.I.C 2200 and see if you got the symptom you need. If so make a new culture. Naming your cultures accordingly will help you long term.
  4. Optional, remove the unwanted symptom using Diphenhydramine.

Doing this for each symptom in one virus sample will lead to a virus with a maximum of 5 symptoms, after the 4th symptom it will not be certain if the 5th will be generated or will replace an existing one. If you want to get the maximum out of your virus you can make two different virus samples with a combined symptom number of 6 and combine those till the result has all 6 symptoms.


Once you have your new designer virus you should get it approved by the CMO (Chief Medical Officer) as per Standard Operation Procedure. The PanD.E.M.I.C 2200 can make a form for you once you name the virus using the machine. A virus that spreads should be approved by the captain and vaccines should be prepared prior to releasing for crew that does not want to be infected by the virus.

Releasing The Virus

So you got the approval of your superior? Perfect! Now it is time to yell at the Chemists once more. They will be able to put the virus samples you made into pills. Be sure to remind them to name the virus! Else it will be called "Blood (1u)" which on its own is not that appealing.


The chemicals listed below are used when creating an advanced virus. Spending the time to make the specialised chemicals (for example Sucrose Agar) will reward you kindly.
As stated in Advanced Diseases, each symptom has a level. The chemicals below will be able to generate symptoms with a certain level, Indicated by the level field in the table.

Understanding Stats

Every virus has a baseline for the statistics which the symptoms will add onto. Feel free to use this Nanotrasen-approved Virus Formulation Calculator to assist in synthesizing a well-crafted virus.

Stealth Resistance Stage speed Transmittable
0 1 1 1

After you are done mixing your disease, stats from the symptoms are added together to make disease stats. Here is what exactly they do:

  • Stealth of 2 or higher will hide your disease from MedHUDs, Health Analyzers and Full Body Scanners. Stealth of 3 or higher will hide it from PanD.E.M.I.C 2200 machine.
  • Transmission is determined as follows: (disease's transmission - the amount of symptoms). 2 or less is blood, 3-5 is contact (3 is by feet, 4 is by hands and 5 is touch in general), 6 or more is airborne. However, sneezing will allow the virus to spread airborne once it reaches stage 4.
  • Chance of advancing a stage per tick is 2% or stage speed, whichever is higher.
  • Cure depends on resistance and amount of symptoms: resistance - (amount of symptoms / 2)
1 or less 2 3 4 5 6 7 8 9 10 11 or more
Sodium Chloride (Salt) Sugar Orange juice Spaceacilin Saline-Glucose Solution Ethanol Teporone Diphenhydramine Lipolicide Silver Gold
  • Chance of it being cured every tick is 15 - resistance, but always between 10 and 20.
  • Transmission affects how much protective gear you must have to protect yourself from it.
