Worms: Roundworm, hookworm and tapeworm

Description
Infection with roundworms, hookworms and tapeworms (including hydatid tapeworm) is uncommon. However, it is still important to observe good personal cleanliness, as infections with hydatid tapeworm or roundworms can have serious effects.


Incubation Period
Eggs or larvae can begin to be passed in the faeces several weeks after infection, depending on the species of worm involved (six weeks in the case of hydatid tapeworms; see hydatid disease on the following page). Symptoms may not be obvious until months or years after the infection was acquired.


Infectious Period
Transmission is possible throughout the period of infestation. Infection will continue until the person is treated. Immunity does not occur. Both adults and children are susceptible.


Controlling the Spread of Infection
Do not exclude the infected person from the centre. Make sure that good handwashing and cleaning procedures are being followed in the centre and at home. Dispose of animal faeces frequently (using gloves) and prevent children from eating dirt. Ensure that animals are wormed regularly with anti-parasitic preparations specific to the worms present in that area. Where hydatid tapeworm is endemic, worm animals every six weeks. Sheep carcasses and infected offal should be disposed of to prevent hydatid infection of dogs (which then infect humans). Stray and free-roaming farm dogs should be restrained to restrict the spread of hydatid tapeworm. Pregnant bitches should be treated for roundworms. Larvae which are dormant in the bitch's body from a previous infection may infect the unborn puppies. Bitches should be re-treated 3-4 weeks after having the puppies.


Treatment
Diagnosing worm infections requires laboratory tests. Seek medical advice. Except for pinworms, treatment of worm infections varies according to the type of worm and the person's symptoms.
