Physicians
Mercantilism or
the rise of commerce, brought not only wealth to the cities, but also disease.
A physicians with a modicum of knowledge would stay in the cities where they
received substantial wages and privileges. Catering predominately to the
wealthy formal medicine was practiced and governed by the church; illness was
divine retribution.
Knowledge of
medicine from ancient text remained for the most part in the hands of the
church with each monastery having an infirmary. Cultivating their own herbal
remedies to treat some monasteries functioned as hospitals for the old, the disabled
and traveling pilgrims.
Knowledge of
herbal remedies lay not only with the church but also with women who performed
practical medicine for their village. Some methods often combined Pagan cures
or invoked spells. Naturally, these practices were frowned upon by the church,
but calling upon the Christian God saints would remedy that.
Where the two
practices collided meant religious persecution as being in league with the
devil which meant execution.
From a compendium of medieval diseases, these were the
most common for our period:
Dysentery (the “bloody flux”)
An infection
caused either by bacteria or amoebas, spread through contamination of food and
water by infected fecal matter.
Symptoms:
(Bacillary) After 1-6 days incubation, watery stools, fever, cramps,
dehydration. In advanced stages, bloody stools, meningitis, conjunctivitis, and
arthritis. (Amebic) Acute form: watery, bloody stools, cramps, fever, weakness.
Chronic form: intermittent diarrhea, mild abdominal discomfort.
Result:
Generally weakened condition.
Note: Endemic
in medieval armies and pretty common in cities. Infantile diarrhea was a
leading cause of death for infants. After the Black Death, many urban areas
instituted public health reforms to improve sanitation and prevent these
enteric fevers.
Ergotism
(“St. Anthony's fire,” “holy fire,” “evil fire,” “devil's fire,” “saints'
fire”)
Poisoning from
a fungal infection of grain, especially rye.
Symptoms:
(Convulsive) Degeneration of the nervous system causes anxiety, vertigo,
aural/visual hallucinations, and the sensation of being bitten or burned;
stupor, convulsions, and psychosis. (Gangrenous) Constriction of the blood
vessels causes reddening and blistering of skin, then blackening, with itching
and burning, and finally necrosis.
Result: 40%
mortality. Lingering symptoms, including mental impairment, among survivors.
Note: Ergotism
was known as a rural disease, particularly of marshy areas, and one that
followed crop damage or famine; especially after a severe winter and a rainy
spring. Children are more susceptible because of their smaller body weight.
Because England did not rely on rye as much as populations on the continent, it
suffered fewer cases of the convulsive type.
Influenza.
An acute,
extremely contagious viral infection of the upper respiratory tract, spread by
inhalation.
Symptoms: After
1-2 days, a sudden onset of chills and fever, headache, backache, muscular
aches, and general malaise; weakness, prostration, nausea, eye pain, mental
confusion. After 1-5 days the respiratory symptoms become more prominent: dry
or sore throat, cough, runny nose. Serious complications include bronchitis and
bacterial pneumonia.
Results: A few months,
maximum, of resistance to repeated infection.
Note: Flu was
not a major worry in the 14th century but became a scourge in the 15th. Because
flu is very contagious it often forms epidemics, generally occurring in the
winter or early spring.
Campaign use:
As you may have
noted, the onset of dysentery is nearly a given while encamped for periods
longer than a week. This would affect both sides, as the besiegers had no
proper sanitation and the besieged having to cope with the extra population
gathered behind its walls. Naturally, a good army would have an abundance of clergy
to help heal the body and soul.
Repeated crop
failure would bring on conditions of famine, but also be a source for
additional disease for the stricken fields. Certainly ruinous for the local
noble and whose adversaries would see this a divine intervention.
A severe winter
would increase the chances of influenza. Keep in mind when designing event
tables, many situations were a natural flow of “cause and effect”. So a
brilliant harvest and well stocked for the winter period, a region would have
less problem with influenza.
