One day. Few at most. In most modern countries death reports are passed to government agency on daily basis. Clerk responsible for them would be surprised that there are none in his area. He will notice sudden drop, and 0 in one category. At least some clerks would call their counterparts in adjacent areas to chit-chat about this impossible coincidence, and,...

If you have European blood in you, are aged between 19 and 45 and are physically fit, the chances of you being brought down by the plague would be very little. Read this Scientific American article for details. Also this livescience article states that the pandemic altered the genes of European people. The Europeans who survived the plague developed ...

This is actually pretty straightforward. The toxin is targeted at a critical organ or function, and the "antidote" is not actually an antidote, but rather provides the same effect as the now-missing organ. A simple example would be a toxin which comprehensively destroys the Islets of Langerhans, while the "antidote" is insulin. A slightly less common case ...

There are three forms of the plague, bubonic (famously from fleas), septicemic (as much from other infected people, like those with bubonic plague) and pneumonic (also from other infected people). If you're going to catch the plague, catch bubonic plague, the others will kill you within 24/36 hours respectively. With bubonic plague you actually have a ...

Luckily for you someone has already developed a large scale system to deliver performance improving chemicals to all the staff employed within a premises, you just need to piggyback on it. The systems are called coffee vending machines and they are ubiquitous in all work environment. Just disguise as a maintainer, add a dispenser to the internal water ...

She would likely need a full round of vaccinations, just like everyone else in the modern world. If anything modern sanitary conditions would be less likely to spread diseases to her. I would personally be more concerned about her starting new outbreaks of diseases here that had been effectively eradicated and are no longer generally vaccinated against. ...

Cleanliness This one's a big one. Getting people to just wash their hands and bodies will go a long way, as the medicine of the time was often not helpful at all, if not downright harmful (leeches, for example). In the 14th and 15th century medicine really started to turn around due to the rejection of commonly accepted authorities, and people instead doing ...

The Black Death - bubonic plague - has a mortality rate of 50-70%, so even with no other measures there's a pretty good chance of any two people surviving at random (about 25% if you take the lower end). However, population-wide statistics are misleading. The mortality rate will be very much lower for fit, healthy people who are well-fed and have no ...

There are many, many diseases that require 'maintenance drugs': Heart disease Requires beta blockers, diuretics, statins for cholesterol management. Risk of death due to heart attack or stroke is elevated, but not predictable - but if you take beta blockers and then stop them abruptly, then the results can be very serious. Diabetes Requires insulin ...

If they're actually drowned there will be mercury in the lungs, because drowning, in general, is the inhalation of a liquid (though the term is occasionally used, loosely, for inhalation of heavier-than-air gasses). Even if the mercury golem is able to reclaim the mercury that was forced into the victim's lungs, the "losses" will be detectable as traces in ...

What about Decompression Sickness? Joe could be kept in a prison kept at a high air pressure - both the toxin and the antidote against the effects of ambient air pressure - (needs not be underwater, even though divers in real world are most aware of this). Joe could be unconscious while his prison is being pressurized, and he will never be the wiser: it won'...

Mermaids perform surgery like this: The patient is laid out on a table with the body part to be operated on at the highest point. A transparent sea shell is then lowered over the target area. Clean air, brought from the surface in shells, is released under the shell until the entire area is "dry". This prevents the blood from clouding the water above the ...

This kind of culture is not unheard of. The most well known (at least to me) is the Fore tribe of Papua New Guinea. As part of their funerary rights they eat the brains of the deceased. This tradition led to Kuru, an endemic degenerative brain disease. If this tradition were more wide spread there are ways it could (health wise) work and ways it would ...

I'm not sure if this one meets your rules or not: Instead of a poison/antidote, how about something addictive with lethal withdrawal symptoms? (Note that there are things close to this in the pharmacy--once your body adapts to them if you suddenly take them away it can't adjust fast enough and you might die.)

Smoking. This was the plot of a science fiction story back in one of the pulps during (I estimate) the early 60s. In this case, the organism is a slow-multiplying pneumococcus bacterium which itself is essentially a minute partly-magical parasite which is stimulated by excess levels of fire magic, which obviously appear in the bodies of the Fire nation. ...

Art Imitates Life Lucky for you, the implantation (or rather reimplantation) of endocrine glands is already a thing. During parathyroidectomy, it is common practice to perform autotransplantation of a portion of the hyperactive tissue. This is usually done in the muscle tissue of the neck or forearm. This is a whopping big parathyroid, much larger than the ...

Within 24-48 hours you'd start feeling the effects of skin conditions from unchecked staphylococci and the like, such as eczema and erythrodermatitis. It is difficult to come up with a hard, reliable source for infection progression since instantaneous immune collapse isn't really a thing. However, ex novo infection can have an incubation as short as 96 ...

It's too easy. There's a kitchen or lunchroom or some such. One day, a lot of trays of food show up. Little signs have a message like so. The meeting didn't happen but the catering order could not be canceled. So here is a lot of free food. Please help us dispose of it so we don't have to throw it away. Please be tidy. The free food includes pizza (both ...

Convince everybody the plague is spread by rats. You know what causes the plague. It's caused by fleas carried by infected rodents, or by inhaling pathogens exhaled by infected individuals. The most effective way you have of surviving the plague is making sure that everybody else in the world knows this as well. Try to convince them that you have authentic ...

Severed molecular bonds should reattach even more quickly due to Van der Waals interactions. I doubt there would even be enough of a wound for a drop of blood to leak out. Am I wrong? I think you may be partly wrong. Your scenario holds if there is no transversal force in the area being cut, for very slow cuts and specific parts of the body. In general, ...

The ability to live for extremely long times without death generally implies the ability to heal from most damage. Given a long enough time, even humans can remove most minor scars. Animals like Lizards, Spiders, and Starfish all regrow lost limbs. The same goes for Psychological trauma, to some extent. Over time, people cope. Some people don't get PTSD ...

Black plague (and hopefully any disease which closely copies it) is carried by fleas. Fleas hate citrus fruit, especially lemons. The woman and her husband own the only citrus grove near the town and normally make their living selling lemons. So their home and grove would be a natural safe zone from black plague. If only her husband hadn't joined the death ...

Assuming no inhalation and it is just their back that is burned it is completely possible for them to survive especially with care, some form of care is importance as the victim will not be moving around much. By care I mean someone to clean the victim, change bandages, and feed the victim. Likewise scar tissue that extensive will hinder mobility even after ...

The Scenario is UNLIKELY As the query stands edited & clarified: Your character should actually be in relatively good shape when her friends reach her! She will almost certainly survive, no RL, no magical herbs needed. The wound you describe is entirely superficial. A slash across the abdomen that does not enter the peritoneal cavity has basically cut ...

Necator americanus (Hookworm) and latrines. Up until the early 1900s, people in the Southern United States would just go #2 by going out to the field and squatting. The problem is that there are parasites, namely hookworm, that can crawl out of old poo and reinfect people by burrowing into their feet when they go out to the same area, to poop again or maybe ...

There are actually several areas where she can help. Germ Theory. She can educate them about the Germ Theory, and how important it is to disinfect stuff. This is a huge life-saver in many areas, the biggest being wound care, midwifery, and surgery. Getting Rid of the Theory of Humors. One theory of medicine that was particularly popular back in the day was ...

Best Weight Loss Solution! Ironically, the pill may well be used at first mostly for its high energy consumption as a weight loss pill. Japanese Workoholics Now Working 23-hour Days If one hour of sleep can subjectively rest you as well as 10 hours of non-pilled sleep, humanity has just gained anywhere between 7 and 70 more hours per week! 23-hour ...

Looking at the history of penicillin, the time traveller in question would need to be familiar with identifying their bacterial cultures. A lot of those bacteria are hard to identify, especially because optics and lens production in Europe did not take off for a while, with the first microscope appearing in 1595. Unless this person is really interested in ...

Leaving biology entirely aside, it depends how much resistance the blade faces. If it faces no resistance at all, which is sometimes how monomolecular weapons are portrayed, then that's because (by whatever means) it's not interacting at all with the body, so how can it do any damage? This is more of a "neutrino blade" than a monomolecular blade, so it's ...

Scurvy from Lind's A treatise on the scurvy. The following relation is no less curious. A sailor in the Greenland ships was so over- run and disabled with the scurvy, that his companions put him into a boat, and sent him on shore ; leaving him there to perish, without the least expediation of a recovery. The poor wretch had quite lost the ...
