Malaria is a
parasitic disease spread through the bites of
mosquitoes. Mosquitoes bite to feed on your
blood and if they have previously been infected
with the malaria parasite, a single bite can
infect you with malaria. Every type of malaria
is serious, but the strain caused by Plasmodium
falciparum is the most serious. Its symptoms can
bring on severe illness very quickly and can
result in death.
Malaria is
present in most tropical regions of the world.
If you are travelling to places with malaria, it
is essential that you take action to avoid
infection (see below). If you have visited
places with malaria, you must be aware of the
symptoms of infection and seek immediate medical
attention should they occur – even if it is
months after you have travelled and you took
malaria tablets to cover your trip. This is
because it is still possible for you to become
infected, although far less likely.
Please see the
following websites for information on whether
the place(s) you plan to visit are known to have
malaria:
Once malaria is
caught, it can be very difficult to eradicate
from your body unless treatment is initiated
quickly. This is because the parasite can lie
dormant, protected from anti-malarial
treatments. If treatment can be started quickly,
the parasite can be killed and most people will
make a full recovery. The service offered here
is not concerned with treating malaria if
caught, but rather the prevention of infection.
If you are
travelling to areas with malaria it is essential
to take the ABCD approach to preventing
infection:
Know your risk
of malaria by checking if it is present in the
places you will visit and understand the level
of risk.
Avoid bites as
much as possible. Stay somewhere with effective
air conditioning and screens on the windows and
doors. Alternatively, sleep under mosquito nets
treated with insecticide. Use insect repellent
and apply frequently. Wear long trousers and
sleeves rather than shorts and T-shirts,
especially in the early evening and at night
when the mosquitoes bite the most.
Take the right
anti-malarial tablets. The Pharmacy2U Online
Doctor service will help you choose the right
medicines and ensure you know how to take it
appropriately. You will need to start taking
them before you travel, and continue to take
them after you return in case some parasites are
incubating in your blood. No anti-malarial
treatment alone is 100% effective so it’s still
very important to take other steps to avoid
being bitten.
Get immediate
medical help for symptoms.
Pregnant women
are more attractive to mosquitoes because of
hormonal changes in the blood and so the risk of
bites is very high. The risks of getting severe
malaria and the risks of damage to you and your
baby are very high. For this reason, the World
Health Organisation advises pregnant women to
avoid travelling to places with malaria.
There are five
medicines predominantly used to prevent
infection with malaria. They are
Doxycycline,
Lariam (mefloquine) and
Malarone (atovaquone plus proguanil), which
are available only with a prescription from a
doctor.
Avloclor (chloroquine) and
Paludrine (proguanil) can also be prescribed
or purchased from pharmacies
Malarone is now
also available as a generic medicine called
atovaquone and proguanil. This contains the same
active ingredients as Malarone and is a fully
licensed UK medicine which is used in the same
way. The Pharmacy2U Online Doctor can prescribe
this generic treatment at significantly lower
prices than branded Malarone.
The right
anti-malarial medicine for you will be dependent
on who you are and your medical history, and
where you are intending to travel and the types
of malaria present. Your GMC-registered GP at
the Pharmacy2U Online Doctor service will review
your medical history and where you are going,
and then authorise the preventative treatment(s)
that is right for you and the trip you are
planning.
