- This map is only intended to highlight destinations
with possible malaria risk.
- Countries in RED are considered
by the World Health Organisation (WHO) to have some malaria
risk. It does not necessarily
mean that the entire country is affected, as malaria
may be restricted to certain areas or regions.
- This map
is an illustrative guide only.
- Malaria risk can change
rapidly and you should always seek accurate and up to
date advice.
- Expert advice must be sought before travelling
to a potentially malarious destination.
- Always consult
a health care professional before travelling to any potential
malaria destination.
South America
Malaria is present in South America, though in many countries
it is restricted to specific areas / regions. The south
of the continent is generally malaria free. For up to date
and accurate advice visit a health care professional before
your travel.
Africa
Malaria is widespread throughout the majority of Africa.
The most deadly form of malaria, falciprium, is also the
most common and certain antimalarial medications may not
be very effective. Always get up to date, expert advice
from a health care professional before travelling to any
potential malaria destination.
South East Asia
Malaria is present in a number of countries throughout
South East Asia, though in some countries it is restricted
to specific areas / regions. Always get up to date, expert
advice from a health care professional before travelling
to any potential malaria destination.
Far East Asia
There is malaria risk in China, though not normally in
densely populated urban centres. There is also some risk
in the northern rural parts of South Korea. Always get
up to date, expert advice from a health care professional
before travelling to any potential malaria destination.
North America, Western Europe, Eastern Europe and Australasia
Malaria does not generally occur in North America, Western
Europe, Eastern Europe or Australasia.

What Determines Your Individual Risk
All visitors to malaria risk areas are at risk
of getting malaria; however, many factors determine the
risk to an individual traveler. Even in the
same locale, these factors can vary widely over time.
From year to year, conditions such as amount of rainfall,
the number of mosquitoes, and the number of infected
persons in the area will change and may produce a different
level of risk than previously seen.
Factors that determine a traveler's risk include:
- Unaware of malaria risk areas
Many U.S. travelers, their healthcare providers, and
tour companies may be unaware that their travel itinerary
includes malaria risk areas.
- Amount of malaria in the area to be visited
Most malaria transmission occurs in rural areas, although
malaria occurs in urban areas in many countries. Low
altitudes with warm temperatures allow for larger populations
of infective mosquitoes. Transmission is generally
higher in Africa south of the Sahara than in most other
areas of the world; in 2002, 73% of imported malaria
cases among U.S. and foreign civilians occurred in
persons who traveled to Africa.
- Time of the year
Seasons with more rainfall and higher temperatures will
have more malaria transmission than colder, drier seasons.
However, in most tropical and semi-tropical countries,
transmission may occur even during cooler months or
periods of less rainfall.
- Type (species) of malaria parasite present
in the area
While all species of malaria parasites can make a person
feel very ill, Plasmodium falciparum causes
severe, potentially fatal malaria. Persons who travel
to areas where P. falciparum malaria is present
should be extra careful to take their antimalarial drug
and to prevent mosquito bites.
- Nighttime exposure to mosquito bites
Because the mosquito that transmits malaria bites at
night, travelers who are frequently out of doors between
dusk and dawn will be at greater risk for malaria.
- Preventive measures taken by travelers
Individual measures, such as taking an effective antimalarial
drug and preventing mosquito bites, are the most important
factors in minimizing risk. While other risk factors
may be difficult to change or avoid, travelers can
greatly reduce their risk of malaria by following recommended
travel precautions.
- Immunity or lack of immunity to malaria
Because malaria was eliminated from the United States
in the late 1940s, most residents have never developed
resistance (immunity) to the disease. Malaria infection
in a non-immune person can quickly result in a severe
and life-threatening illness.
In addition, many healthcare providers and laboratories in
the United States rarely see cases of malaria and may
be unfamiliar with the diagnosis and treatment of the
disease, and this can delay effective treatment.
Know the Facts
Every year, millions of United States residents travel
to countries where malaria is present; about 800 cases
of malaria are diagnosed in these returning travelers
each year. From 1985-2002, 78 U.S. travelers died from
malaria.
Persons who are traveling to malaria risk areas can almost
always prevent this potentially deadly disease if they
correctly take an effective antimalarial drug and follow
measures to prevent mosquito bites.
Know the Symptoms
Despite these protective measures, travelers may become
infected with malaria. Malaria symptoms can include:
- fever
- chills
- headache
- flu-like symptoms
- muscle aches
- fatigue
- low blood cell counts (anemia)
- yellowing of the skin and whites of the eye (jaundice)
If not promptly treated, infection with Plasmodium falciparum,
the most harmful malaria parasite, may cause coma, kidney
failure, and death.
When Symptoms Appear, Seek Immediate Medical Attention
Malaria is always a serious disease and may be a deadly
illness. Travelers who become ill with a fever or flu-like
illness either while traveling in a malaria-risk area
or after returning home (for up to 1 year) should seek
immediate medical attention and should tell the physician
their travel history.
