The incidence of tuberculosis began to decline in 1801, which was prob
ably due to improving socioeconomic conditions (certainly not the effo
rts of the medical profession). Patients cannot be treated unless they
are detected, which underlines the importance of notification and cas
e finding. Full multiagent chemotherapy is necessary to give the best
chance of permanent cure and to prevent the emergence of resistance; c
ompliance with treatment is increased by making it readily accessible
and increasing the degree of supervision. With the resurgence of inter
est in tuberculosis since the rising incidence of the late 1980s a rev
iew of the state of diagnosis and treatment is due. This one covers so
me areas of current interest: the role of vaccination, chemoprophylaxi
s, tuberculosis and HIV, new methods of diagnosis, drug resistance and
alternative approaches to treatment.
