Burden of fungal infections in Algeria.

We report for the first time in Algeria and provide burden estimates. We searched for existing data and estimated the incidence and prevalence of fungal diseases based on the population at risk and available epidemiological data. Demographic data were derived from the National Office of Statistics (Office National des Statistiques: ONS), World Health Organization (WHO), The Joint Nations Programme on HIV/AIDS (UNAIDS) and national published reports. When no data existed, risk populations were used to estimate frequencies of fungal infections, using previously described methodology. Algeria has 40.4 million inhabitants, and probably at least 568,900 (1.41%) of Algerians have a serious fungal infection each year. Recurrent vulvovaginal candidiasis (485,000) and fungal asthma (72,000) are probably the commonest problems, as there are over 1 million adult asthmatics. Candidaemia is estimated in 2,020 people, invasive aspergillosis in 2,865 people, and intra-abdominal candidiasis in 303 people; these are the most common life-threatening problems. AIDS is uncommon, but cancer is not (45,000 new cases of cancer including 1,500 in children), nor is COPD (an estimated 317,762 patients, of whom 20.3% are admitted to hospital each year). A focus on improving the diagnosis and epidemiological data related to fungal infection is necessary in Algeria.
