Pen.png This page needs revising!

The following page is out of date and/or needs to be revised. If the page's guide needs revision, see here for an example.
The revision reason is: "With the rework and addition of extrapolators, entries relating to symptom acquisition or virology chemicals are outdated"



There are many diseases that can affect you in space! The following will come in handy for virologists, traitors, or any unfortunate soul who's come down with a case of brain rot.

Virology 101

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

The first, most important way to prevent 99% of infections is proper hazard wear and knowing how to keep the infection from spreading.

The Clothes

The following will protect you from the dangerous infections of space, each giving more and more (till total) protection against infection:

Isolation

If you or another crew member is infected, do not spread the infection further. Seek the isolation bay of the medical wing, or head to a room no one will enter but yourself and other infected.

Sterilization

Cleaning blood spills from the ground will prevent contact contamination. Make sure blood is cleaned from the floor at all times; any blood splatter out there could hold a dreaded space infection. Contact a janitor if you see blood on the floor, do not interact with the blood if you suspect possible infection chance. Any object or floor that has infected blood on it can infect anyone who handles or touches it.

Methods of Infection

The following are the various ways a disease can spread, keep this in mind at all times:

  • 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.
  • 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.
  • Blood - The infection will be spread by the bodily fluids of the infected person.
  • 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.

Curing an infection

Every infection is vulnerable to one substance (or combination of two). To find it, you can put an infected blood sample in the PanD.E.M.I.C 2200 machine or use a health analyzer on an infected patient. Administering the substance to the patient (may require multiple injections) should cure him. Alternatively, if you have produced a vaccine, a simple injection should cure the patient.

Pandm.gifPanD.E.M.I.C 2200

This machine creates vaccines from the blood of people who have been cured.

Use:

  1. Take a blood sample with a syringe.
  2. Place sample into a beaker or bottle.
  3. Load beaker into machine.
  4. Select vaccine you wish to have.
  5. Take vaccine bottle it produces.

Additional uses:

  • Reveals the cure to any infected blood sample without needing to inject a living creature.
  • Shows the stats and symptoms of a virus

Viral Extrapolator

The viral extrapolator is a bulky, slow device, used to scan and extract diseases on the go. It has two modes, which can be toggled by using it in-hand

Scan Explorator scan.gif tells you what diseases are held within the target, if any, what symptoms they have, and what stage they are at.

Extract Explorator sample.gif can be used to harvest an advance disease from the target. If used on a culture bottle, it can be used to isolate a single symptom. The extrapolator takes twenty seconds to extract a disease, and one minute to isolate a symptom. There is a two minute cooldown before the extrapolator can be reused. It cannot isolate symptoms of a level higher than seven.

Upgrading the extrapolator:

By using a screwdriver on the extrapolator, you can remove its scanning module. Replacing it with a higher tier scanning module significantly lowers its cooldown and use times, as well as allowing isolation of higher level symptoms.

Symptom hunting: Some objects can contain trace samples of the disease that the extrapolator can make into a culture. Many of these start with random diseases at roundstart, and can be harvested. This is the primary source of level nine symptoms. These items are as follows:

  • Bloodstains. Only dried blood or old gibs will spawn with diseases.
  • Vomit. Only crusty, dried vomit will spawn with diseases.
  • Syringes. Only used syringes, found in maint, will spawn with diseases
  • Mice and rats.
  • Any item a sentient disease has used Secrete Infection on
  • The glands of Wumborian Fugu always have a disease containing Pituitary Disruption
  • Vector, the virologist's pet hamster, always has an extractable disease.
  • Blob Spores created by the Blob Spores symptom always have the disease that spawned them
  • Macrophages always contain the disease that spawned them.

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. The following diseases are Simple Diseases that cannot be affected by the PanD.E.M.I.C 2200 or a Viral Extrapolator, and have no stats or symptoms.

Disease Name Vector Name Source Description Spread Cure
Alien Parasite Xenomorph Alien A facehugger has implanted an embryo inside of the body of the victim, which will grow until it kills and destroys the body while spawning a larva. Special Surgery
Zombie Infection Romerol Syndicate Uplink A rare infection, which lies dormant in the victim. If the victim dies before it is cured, it will rise as an aggressive zombie, who will then transfer the infection to anyone it manages to scratch. The infection consists in a tumor located inside the head. Special Surgery

Advanced Diseases

You are able to create your own advance disease with different symptoms, which will have buffs, debuffs and bonuses!

You will start out with two advance diseases, the cold and the flu. The cold will have the sneeze symptom and the flu will have the cough symptom. They have almost no effect if they infect people, but you need them to acquire more symptoms.

The Pandemic can create culture bottles (basically copies) of existing viruses, so you won't run out while experimenting.

Multiple Diseases

A person has three slots for advanced diseases, with a fourth slot for sentient diseases. The slot a disease fits into is determined by Severity. If a disease tries to occupy an already occupied slot, and its transmission is higher than the resistance of the disease already in the slot, it will drive the disease out and take its place

Modifying Symptoms

To obtain a new symptom you need to mutate an existing virus. This involves adding a chemical to the virus, which will generate a new symptom. Rarer and harder to acquire chemicals will yield more potent symptoms. You will start with enough chemicals to create a powerful disease, as long as you use them carefully. You can also insert an isolated symptom into your main virus, by moving 1 unit of the isolated culture to the main mix with a dropper. It will not work every time and may need to be repeated a few times.

Basic chemicals

These are the basic chemicals for virus mutation. These can be added to a culture to gain a symptom from a large pool- but it's about half as efficient as mixing advanced chemicals.

  • Virus Food: You can make virus food with Water and Milk. Virology lab has its own Virus Food Dispenser. Mixing this with a disease will give that disease a symptom of level 1 to 2. Pure virus food is the only way to get level 2 symptoms, so, unlike plasma and mutagen, it is useful alone.
  • Unstable Mutagen: You can use mutagen to mutate your disease and give it a symptom of level 2 to 4. Virology starts with a 30u bottle of mutagen.
  • Liquid Plasma: Plasma can be used to mutate your disease to give it a symptom of level 4 to 6. Plasma in liquid form is generally in very limited supply, unless mining and chemistry cooperates with you. Virology starts with a 30u bottle of liquid plasma, and in some station layouts with extra plasma bars.

Advanced Chemicals

Using these will allow you to both save time and resources when trying to acquire the symptoms you want.

  • Anomalous Virus Food: Anomalous Virus Food can be used to mutate your disease and give it a level 0 symptom. It is made by combining pure Laughter with virus food. Level 0 symptoms tend to be statistically similar to other symptoms, but have an unusual effect- good for gimmicks!
  • Virus rations: Virus rations can be used to mutate your disease and give it a level 1 symptom. It is made by depleting Virus food with Synaptizine. Level 1 symptoms almost universally boost stats, but have very little effect. Level 2 symptoms tend to be a bit better, so it's wise to leave virus food as-is.
  • Mutagenic Agar: Mutagenic agar can be used to mutate your disease to give it a level 3 symptom. It is made by mixing Unstable mutagen and virus food together. Level three symptoms tend to be either decent stat-boosters, or subpar active symptoms.
  • Sucrose Agar: Sucrose agar can be used to mutate your disease to give it a level 4 symptom. It is made by mixing Sugar or Saline Glucose Solution and Mutagenic agar together. Level four symptoms are quite weak, so there is very little point to mixing this.
  • Weakened Virus Plasma: Weakened virus plasma can be used to mutate your disease and give it a level 5 symptom. It is made by weakening virus plasma using Synaptizine. Level 5 symptoms tend to be some of the strongest stat symptoms
  • Virus Plasma: Virus plasma can be used to mutate your disease and give it a level 6 symptom. It is made by mixing liquid plasma with virus food. Level 6 symptoms are the strongest active symptoms available without uranium or Highly Unstable Virus Food
  • Advanced Virus Food: Highly Unstable Virus Food can be used to mutate your disease and give it a level 9 symptom. You only get one unit, which is inert until a single uranium sheet's worth of uranium is added, but every single level nine symptom is powerful in its own way. The symptom you get will likely define the disease you make on any given round. Highly unstable virus food was removed, and replaced with the viral extrapolator.

Uranium Gels

These chemicals require large quantities of liquid uranium (obtained by grinding uranium bars). You'll require the help of mining to make these.

  • Decaying Uranium Gel: Decaying Uranium Gel can be used to mutate your disease and give it a level 6 or 7 symptom. It is made by combining 1 virus food with 1 liquid Uranium. Efficient compared to Unstable gel, but slower to use.
  • Unstable Uranium Gel: Unstable Uranium Gel can be used to mutate your disease and give it a level 7 symptom. It is made by combining 1 virus plasma with 5 liquid Uranium. Level 7 symptoms contain potent stat symptoms, and several esoteric symptoms.
  • Stable Uranium Gel: Stable Uranium Gel can be used to mutate your disease and give it a level 8 symptom. It is made by combining 1 plasma with 10 parts liquid Uranium and 10 parts liquid silver or gold. Level 8 symptoms contain some of the most potent healing symptoms, as well as some very difficult to deal with deadly symptoms.

Synaptizine

Synaptizine, aside from being a base chemical, will remove one random symptom to any virus it comes in contact with. It's important if you intend to isolate a specific symptom. For example, if you mutate your Cold virus and it acquires the Toxic Filter symptom, you can try and add synaptizine to it to create a virus which only has the Toxic Filter symptom.

Spaceacillin

Spaceacillin will "Falter" a disease, making it unable to spread by any method but injection. Good for meme diseases, or if you wanna meet a transmission threshold without fucking everyone over

Cryostylane

Cryostylane will Preserve a disease, making it unable to be mutated any further. If you finish a disease, you should Preserve it so it can't be edited, and so multiple diseases of different severity can be loaded into one bottle


Formaldehyde

Formaldehyde will neuter one random symptom when mixed with a virus. This disables its effects while keeping the attributes intact. This is useful for meeting threshold values without making the virus deadly. NEUTER YOUR STAT SYMPTOMS, ALWAYS. UNLESS IT'S SOMETHING WITH AN EFFECT YOU ACTIVELY USE, ALL AN UNNEUTERED STAT SYMPTOM WILL DO, EVEN IF THE DISEASE IS INTENTIONALLY DEADLY, IS MAKE THE DISEASE GET NOTICED FASTER, AND, SCARE PEOPLE IF YOUR DISEASE IS GOOD, PROBABLY GETTING YOU LYNCHED. NEUTER YOUR FUCKING SYMPTOMS. YES, FEVER AND ITCHING CAN DO SLIGHT DAMAGE. NEUTER THEM ANYWAYS, DAMMIT

BABBY'S FIRST VIRUS

Viro action.png
 
Eyre I, the Virologist says:
"Psst, hey kid. Over here. Look at you, still fresh off the arrivals shuttle. Take the biosuit off, it'll only slow you down. Listen up- I'm here to teach ya exactly how to get robust at Virology, provided you can wrap your head around some simple concepts. I've hijacked this outdated nanotrasen standard-issue virology guide to teach YOU how to be a better Virologist than those Nanotrasen quacks!"

Alright, since most people can't seem to grasp it: Virology is fucking SLOW! So this means you're gonna want to do a few things to make it faster!

1. Know what virus you want to make! I cannot fucking stress this enough. Random symptom isolation will never get you anywhere fast. Make a recipe for what you want, and then go aquire the symptoms

Virology with extrapolator:

2. Grab the spare extrapolator from the biohazard closet. You'll need extra to save time. Whenever you stop in medical, check the medical protolathe to see if you can upgrade the extrapolator with a new scanning module. Use a screwdriver to remove the old one, and shove the new one in. This lowers cooldown, massively speeds up the extrapolator's speed, and allows you to isolate higher-level symptoms

3. get a medical belt for your extrapolators. Consider grabbing a bio-bag for cultures. If CMO is nice, ask for the budget card- getting the budget allows you to skip maint-crawling entirely

4. Use the extrapolator to scan dried blood, old rotting gibs, crusty old vomit, used syringes, rats, etc, for viruses. if you see any symptom that fits the recipe, grab the culture! ALTERNATIVELY, with the budget, go to cargo and buy as many VIRUS SAMPLE CRATES (not Virus Crates) as you can. All the cultures will fit in the bio bag, and it can save cargo crate-dragging time if you go into the shuttle and pack them into the bag yourself. If you lack a budget, offer to do the viro bounty for virus crates- it's usually worth 4-8k, enough for 2-4 crates. If you want level 0 symptoms, find a source of banana juice

5. Once you have all the level 9s (and hopefully 8s and 7s to save time) you need, go back to viro. Make sure you have a level 3 scanning module at minimum. If you're missing any level 0-8 symptoms, get the virus chem for that level

6. Extrapolators make gaining a symptom easier. Lay a base culture out, any culture, and add 1u of the base culture. Add 4u of the desired chem, one drop at a time, and check if it has the symptom. If not, empty until it does. When it has the symptom, isolate it with the extrapolator. This is faster than 1u at a time (this being due to the fact that you're lowering the symptom pool by the amount of symptoms already in the culture, raising your chance).

7. Take your extrapolators, and begin using both in tandem (avoiding cooldowns) to extract every other symptom you need from your collection of culture bottles

8. Once you have every symptom you need, begin putting them in an empty beaker, neutering symptoms from their base culture when applicable. After reaching 4 symptoms, make a culture every time you try to add a new symptom, due to how symptoms may delete other symptoms at high symptom count. Add it one-at-a-time to the main culture, and always drip the single symptom into the main culture, not the other way, as this minimizes the chance of symptom deletion (the check is called per-symptom on the culture being added, so adding only a single symptom only checks it once)

9. After it's done, label it, make a backup culture, and Falter or Preserve it as necessary. Preserving a virus allows multiple to be placed in one culture bottle!

Virology without extrapolator:

2. You'll need five beakers when you get started making your virus:

  • Fill the first beaker to the brim with virus food and put it on the table. This is for level one and two symptoms.
  • Fill the second beaker with thirty units of virus food, and dump your entire mutagen bottle in. This is for level three symptoms.
  • There is no beaker for level four symptoms. Four is an unlucky number or some shit, and, more importantly, all level four symptoms suck
  • Fill the third beaker with ten units virus food, ten units Plasma, and then ten units of Synaptazine. This is for level five symptoms. THE ORDER IS IMPORTANT. PUT SYNAPTAZINE IN BEFORE PLASMA AND YOU'LL GET A BEAKER OF VIRUS RATIONS AND PLASMA, WASTING YOUR CHEMS. DONT DO IT.
  • Fill the fourth beaker with ten units virus food and ten units of Plasma. This is for level six symptoms
  • If you have the clown's can of laughter, you can fill a fifth beaker with ten units of virus food and the entire can of laughter for level zero symptoms

3. Lay out your Formaldehyde, Synaptazine, and Unstable Virus Food.

4. Finally, set an empty beaker out, and either Rhinovirus or the Cold. The Cold's symptom is Coughing, and Rhinovirus is Sneezing. I am a plasmaman, so all my diseases need high transmission- I prefer to set out rhinovirus.

5. Whichever symptom you choose to start with, drop a drop of formaldehyde in immediately! this neuters the symptom so your plague doesnt alert and scare people, which is bad regardless of your antag status. Remember to use your dropper, after setting it to one unit!

6. After you lay out your beakers on the table near the pandemic, situate yourself on a tile adjacent to the tables containing the reagents and your PANDEMIC machine. You will never have to move during this procedure- which saves valuable time.

7. With your recipe in mind, begin placing one unit of your starting symptom culture and one unit of the virus chem corresponding to your disease into the empty beaker. Do NOT place your virus chem into your culture, or your culture into your chem- it will set you back by an insane amount!. After you make ONE reaction, place the empty beaker in the pandemic-You never need to pick any beakers but this empty beaker up during the process- and check the symptoms. If you got what you wanted, create a culture, save your previous culture if it's the starter, you will need it later, or get rid of it if it's a random step in the process, and repeat with the chem for the next symptom, doing symptoms you will neuter first and neutering them as you get them. Repeat until you reach a total of four symptoms. To reiterate step five, ALWAYS use a one unit dropper! it makes you far more efficient with chem usage- if you use a dropper, your starting chems will usually last an entire round!

8. Upon reaching four symptoms, a virus has a chance to lose symptoms on gaining new ones. To avoid this, make a culture of your four symptoms, name it, and put it aside. Take your starter culture out, and begin the step 7 process. Once you get the fifth symptom, use the step seven process with synaptazine to remove the starter symptom, and finally repeat the step seven process one last time to get the last symptom. By now, you should have two cultures- one with four symptoms, and one with two (or one, five symptom diseases exist)

9. Finally, repeat the step seven process one more time, but using the two cultures, instead of a chem and a culture. There is no reaction sound for this mixing! Once you reach the desired number of symptoms (yes, adding symptoms via mixing can delete symptoms just like adding them via chems does), name the virus, and make a culture! you're done! yay! Consider Faltering your disease with Spaceacillin if you don't want it to spread, and/or Preserving it with Cryoxadone.


Understanding stats

After you're done mixing your disease, stats from the symptoms are added together to make disease stats. Viruses have a default of 0 in every stat.

  • Stealth: If stealth is 2 or higher your disease will be hidden from medHUD and scanners. Generally it will also hide the warning signs of symptoms before they activate.
  • Transmission: Improves the chance each tick to spread the virus, increases the amount of protection you need to prevent infection, determines the infection vector, and is needed to override other viruses.
    • The infection vector is calculated with (disease's transmission - amount of symptoms). 2 or less is blood, 3 is fluid contact, 4 is skin contact, 5 is airbone. The Sneezing symptom forces sporadic airborne spreads, but does not otherwise affect this.
    • When infecting someone who already has a virus, if the infecting virus' Transmission is higher than the other virus' Resistance, the latter will be overridden by the former.
  • Stage speed: Increases the chance of advancing a stage each tick. It will be 2% or stage speed, whichever is higher.
  • Resistance: Makes the virus harder to cure; determines the required chemical to cure, decreases the chance of it being cured each tick when in contact with the cure, and defines how resistant the virus is to being overridden by other viruses. Sentient diseases have a fixed cure, and don't rely on resistance to determine their cure.
    • The chance of it being cured every tick is 15 - resistance, but always between 10 and 20.
    • The cure is determined by [resistance - (amount of symptoms / 2)].
1 or less 2 3 4 5 6 7 8 9 10 11 or more
Sugar Ethanol Table Salt Spaceacillin Saline-Glucose Solution Miner's Salve Leporazine Concentrated Barber's Aid Lipolicide Haloperidol Krokodil
  • Severity: Severity determines how virus shows up on a medhud, and which slot a disease occupies. Severity adds up in a manner different to other stats- A severity score below 0, or equal to or above five will be added normally. A severity of 1 or 2 will be added to a maximum of 3. A severity of 3 or 4 will be added to a maximum of 4. Severity also determines which of a person's three disease slots a disease occupies, unless the disease is sentient. Severity is unique in that stats will modify it
Severity: 0 or less 1-4 5 or more
Slot: 1 2 3

General Tips

  • You can get plasma and uranium from the medical autolathe if mining has picked it up. No need to waste time going to the ORM.
  • The clown will typically be happy to give you his canned laughter for Anomalous Virus Food. if not, a single ground-up banana cream pie mixed with sugar is sufficient for as much laughter as the can usually has
  • Never make sucrine agar unless you absolutely need a level four symptom for some ungodly reason
  • If you wear the biosuit, you're an idiot. The only time you need to wear that is when working with patients or monkeys, and it slows you down. If you release a disease as a traitor, you should have immunized yourself beforehand- a biosuit sticks out like a sore thumb
  • ALWAYS make your diseases beforehand. Have a recipe ready to work with any given symptom. This is the MOST IMPORTANT part of being good at virology.
  • Never use pure mutagen or pure plasma. Always make virus chems, it doubles your efficiency.
  • If you want to kill a single person, single target viruses using Viral Aggressive Metabolism can be just as effective as a deathchem. If you're an antagonist, and want to be sporting, try poisoning your victim with a powerful zombie virus. In my experience, people love when you do this.
  • While spreading a low-effect beneficial disease may be tempting, designing a combo of multiple diseases (Called a "Trifecta") at varying severity levels, is usually the best way to go. A good trifecta usually has multiple level 9 symptoms, and can take most of a round to create- but it's worth it.
  • For stealth: 2 stealth is the only time it matters outside of thresholds. The only time stealth is used outside of this is for extrapolators.
  • White shoes protect from infection sources on the ground, such as bloodstains, vomit, and Exolocomotive Xenomitosis mass
  • If you want a virus to be spread exclusively via Exolocomotive Xenomitosis or Macrophage, falter the virus containing that symptom. It won't spread via transmission, but will still spread via infected floor or macrophages. Note that when these viruses meet their threshold that spreads all host viruses, they won't spread faltered versions.

The Black Death

Being a traitor virologist allows you to finally come out of your shell and release those negative recipes you've been aching to test, and put those level nine symptoms to the true test!

  • Sabotaging the Pandemic is usually a good idea, as it can create a vaccine for a cured virus which is cheap and easy to distribute, even if the virus is extremely resistant.
  • Sabotaging the holodeck computer is also a good idea because its Emergency Medical simulation also contains a Pandemic.
  • Sabotaging chemistry can stop them from making most of the chems that can cure viruses.
  • A dropper works as a 1-5 unit hypospray when used on a target not wearing any eye protection.
  • An infected monkey in medbay is another easy way to spread a disease
  • Immunize yourself before releasing your death plague!
