Leishmaniasis is a
parasitic disease that is found in parts of the tropics, subtropics and
southern Europe. The infection is caused by contact with Leishmania
parasites which are spread by the bite of infected sand flies.
There are different types of
leishmaniasis; the most common forms are cutaneous, which cause skin
sores, and visceral leishmaniasis, which affects some of the internal
organs of the body (e.g. spleen, liver and bone marrow).
Incidence
The number of new cases of cutaneous leishmaniasis a year is thought
to be about 1.5 million. The number of cases of visceral leishmaniasis is
thought to be about 500,000.
Prevention
There are no
vaccines or drugs to prevent leishmaniasis. The best way for travellers to prevent
infection is to protect themselves against bites from sand fly bites.
Avoid outdoor
activities from dusk to dawn when sand flies are most active:
·
Minimize the amount of skin exposed, long-sleeved shirts,
pants and socks should be worn.
·
Apply insect repellent containing DEET or Citridiol to any
exposed areas.
·
When indoors:
·
Stay in well screened or air-conditioned areas.
·
Spray living/sleeping areas with an insecticide to kill
insects
·
Use a bed net soaked in permethrin or deltamethrin and
tuck it under your mattress. permethrin or deltamethrin can
also be used for sheets, clothing, screens and curtains.
Symptoms
·
The symptoms of visceral leishmaniasis usually
include fever, weight loss and an enlarged spleen and liver and some
abnormal blood tests (ie. Low red blood cell count, low white cell count
and low platelet count.)
·
People with cutaneous leishmaniasis have one or more
sores on their skin. These sores can change in size and appearance over
time. The sores can be painless or painful. Some people also have swollen
glands near the sores.
Treatment
Therapy varies depending upon the clinical form of leishmaniasis, the
infecting species and the region where infection is acquired. Hence
travellers concerned that they have acquired this disease should see
their travel medicine specialist clinic or an infectious disease
specialist.
