Bacillus Bridgeus

The ultimate disease — but who needs a cure?

Bridge is a highly contagious, progressive and incurable disease. The World Heath Organization (WHO) estimates there are currently between 50 and 100 million infected people worldwide. Unlike other epidemics of this scale, bridge attacks primarily in developed countries (I think that the authors have no idea about what is going on in developing countries!!!!!!). While rarely fatal, the disease has enormous negative impact on the lives of infected individuals and on the whole society.


Earlier theories assumed that bridge is an addictive drug, much like alcohol. In 1976, however, two independent teams of Dutch and American scientists isolated Baccillus bridgeus, a very small bacteria causing bridge. This discovery explains why earlier treatment programs such as ‘Bridge Players Anonymous’ were unsuccessful.

Bacillus bridgeus transmits primarily via contact with bridge players. Once inside human body, it lodges itself in the brain, where it attacks the parts responsible for higher cognitive functions. During the tertiary stage (see under symptoms) of bridge, the patient's brain is little more than a tool for Bacillus bridgeus to transmit itself to other victims.

Origins of the epidemics

The bridge epidemic started around 1890, almost simultaneously in Great Britain and in the USA. It appears that a relatively benign bacteria causing whist mutated itself into Bacillus bridgeus. While the reasons for this mutation are not completely determined, a likely hypothesis suggests that it was a result of exposure of the whist bacteria to high doses of alcohol and boredom among civil servants in certain parts of the British Empire (mostly Egypt and India).

Symptoms and relief

Stage 1 - which is not at all unpleasant, the infected individual enjoys an occasional social game of bridge and does not think of bridge in between those. Only a small area of brain has been attacked and there are not infrequent reports of a spontaneous arrest of the disease and even of complete recovery.

Stage 2 - usually marked by the victim starting to analyze the hand just played. It can be also recognized from the fact of the patient buying the first bridge book, usually with a title like Improve your play technique or Killing defense at bridge. During this stage the victim often joins a bridge club and participates in the first tournament. Once this happens, the prognosis is almost always bad.

Stage 3 - can be recognized by the victim being able to name the current World Champions, winners of the Bermuda Bowl and other major tournaments. It is also marked by the patient owning a full bookshelf of bridge books and/or a subscription to a bridge magazine. At this stage the infected individual loses interest in other pursuits, is a common sight on the tournament circuit, and often dabbles in bridge theory. In extreme cases the victim neglects even the most elementary functions such as eating or personal hygiene.

While there may be periods of marked improvement, which often lull the patient and concerned relatives into a false sense of security (with the patient thinking ‘I can take it or I can leave it’), it is important to recognize that a relapse is unavoidable. Nevertheless, some symptomatic relief can be achieved by simple methods such as getting the victim interested in other pursuits (sex, fly-fishing, crocheting), taking away his/her pocket money, and keeping the patient locked up during club games and local tournaments.


Currently, the only available cure for bridge is lobotomy. This is performed only in extreme cases.


Conservative estimates indicate that it is 65 times as contagious as chess and about 5-6 times as the most infectious of the so called Nintendo viral group (which usually attack only children and adolescents and disappear, without causing any damage, upon victim's reaching the adulthood). Thus it is very hard to prevent a bridge infection.

The current most-recommended preventative is to avoid any contact with bridge players. If complete avoidance is impossible, do not allow the infected individual to talk about bridge and never, ever agree to be ‘introduced to bridge’.

Recently published results of a 20-year long study by John R. Williams et al of the Hopkins University lead to surprising conclusions. It is not particularly risky to be in company of bridge carriers, when their number is divisible by 4. On the other hand, it is extremely dangerous to be alone with 3 (or 7, 11, etc.) bridge players for a prolonged period of time (a cruise, chalet holiday, etc.). The reasons for this dichotomy are at present completely unknown and underline our lack of knowledge about Bacillus bridgeus.
