General Statistics (11)
Area: 2,376,400 km² Population: 28,400,000 inhabitants (1996),
31,000,000 estimated for 2000 Capital: Algiers (2,500,000
inhabitants) Other important towns: Oran, Annaba, Constantine,
Tlemcen, Béchar, Tindouf, Elgolea, Timimoun, Tamanrasset,
Insalah.
| Epidemiological facies
Algeria can be characterised as having on the one hand centres of
autochthonous malaria caused by Plasmodiumvivax, and imported
malaria Introduced from Niger and Mali on the other. These are for
the most part caused by thePlasmodium falciparum.
Today there remains only the IHERIR centre near Djanet in the
Willaya d’llizi (see map)

The latest available statistics clearly indicate that with less
than 250 cases a year, malaria is today no longer a public health
problem (see table) (10) compared with the period from 1952 – 1961
when there were more than 50,000 cases a year.
Year | Cases declared
| Autochthonous cases | Imported cases | Undefined cases | | 1994 | 206 | 64 | 137 | 5 | | 1995 | 107 | 12 | 95 | 0 | | 1996 | 221 | 24 | 186 | 11 |
| Vectors
Algeria’s anopheles were the subject of much study at the end of
the sixties (4 and again in 1983 before the opening of the
Trans-Sahara route.(6). The species described at the time were:
Anopheles dthali
(Iherir, Béchar,in the south), Anopheles
hispaniola (everywhere in Algeria) , Anopheles
labranchiae (in the north), Anopheles
multicolor (everywhere in Algeria) , Anopheles rhodesiensis
rupicolus (Iherir and Amais), Anopheles rufipes
broussesi (Iherir and Djanet), Anopheles sergentii
(everywhere in Algeria) , Anopheles
algeriensis (Batna, in the north east). The main malaria vectors in Algeria are Anopheles dthali, An.
multicolor, An. sergentii et An. labranchiae (6).

| Chemoresistance
Not documented.
A case of imported Plasmodium falciparum malaria was
signalled as being Chloroquine-resistant. (8).
| Vector Control
Vector control is one of the strategies used by the INSP and
consists in anti-larvae and anti-adult insect action, but there is
no documentation on the subject.
| The National Anti Malaria Program
A malaria eradication program (MEP) has been established by the
INSP.
Drs. ATEK and KABRANE are employed on a full time basis and the
program consists of 12 staff members (3 doctors, 3 technicians, 1
engineer, 2 administrators, and 3 agents)
The program’s objectives are to prevent the re-transmission of
malaria and to help warn about the risks of re-introduction of the
disease. They have developed a 5 point strategy for this: 1. Reinforced
surveillance system Notification of cases, Analysis of epidemiological facts. Analysis of results obtained from haematological
screening. Classification of malaria zones. Haematological and sero-epidemiological investigations Entomological investigations 2. Organisation of
anti-malaria actions · Treatment for the carriers of the
parasite. · Anti-larvae and anti- imago insect actions
3. Staff training and
reorientation 4. Health
Education Awareness campaign for medical and paramedical staff. Recommendations and advice for travellers going to malaria
infected regions.
5. Stimulation of
research activities: Updating the anopheles map, Study of how likely the Algerian anopheles risk infection by
strains of “tropical” plasmodial species, Carrying out sero-epidemiological investigations Creation of a culture for the parasite so as to obtain
anti-genes.

| Advice to Travelers
Algeria should be classified in chloroquine-resistance group
1: · no Plasmodium falciparum · If there is Plasmodium falciparum , it is chemosensitive
to usual antimalarial drugs · Possible presence of Plasmodium vivax Travelers should be advised to take a chemoprophylaxis with
chloroquine. In practice however, the risk of contracting the
disease is so limited it is considered non-existant and so no
chemoprophylaxis is needed. For those wishing to visit the Iherir Oasis, it is advised to
take only vector control measures such as mosquito repellent skin
cream
