Introduction: Intestinal parasitosis are neglected diseases that are still a major public health problem in tropical countries. Objective: This study was undertaken to evaluate the impact of seasons in a subtropical climate on the occurrence of intestinal parasites in children under 5 years of age. Patients and method: The study concerned 504 cases of children under 5 who consulted at the "Afia-Sake" Reference Health Center and carried out direct parasitological examination of stools. Each patient underwent a fresh optical microscopic stool examination by the direct physiological saline technique and positive results were reported for the different subtropical climatic seasons corresponding to the date of each child's passage to the Health Center. Result: The prevalence of intestinal parasitosis is 94%, the most affected age group is between 18-29 months with a predominance of female. We did not find a statistically significant difference between the presence of parasites and the seasons; for, the risk of having mono-parasitoses during the long rainy season and the risk of having poly-parasitoses during the short dry season appeared equal. conclusion: Periodic chemoprophylaxis with deworming, drinking water supply without health risks, hygiene and sanitation and veterinary public health measures should help to curb these endemics.

Background: HIV infection continues to wreak havoc around the world. Women are not spared, especially pregnant women, with low levels of education or information, transmitting HIV to their children. This study aims to assess the level of knowledge of women in reproductive age on the prevention of mother-to-child transmission of HIV / AIDS in the AFIA-Sake health area in the Democratic Republic of Congo. Method: This study is descriptive, involving 315 women aged 15-49 years from the AFIA-SAKE health area. The data collected by questionnaire were checked, captured and analyzed. The frequency of observations was calculated and the proportions were compared for accuracy when the CI was 95%. Results: The study shows that only 10% of women are aware of the prevention of mother-to-child transmission of HIV. Antenatal consultation is the excellent channel of communication. Among the women interviewed on antiretrovirals, 56% do not know when they will be given to pregnant women diagnosed with HIV; 63% do not know the value of administering antiretrovirals and 78% do not know when antiretrovirals will be given to the newborn. Conclusion: Achieving the goal of sustainable development for an HIV-free generation, with zero new infections in children and no HIV-related deaths, involves informing women of reproductive age about the prevention of mother-to-child transmission. HIV child through increased enrollment of girls, introduction of sex education as well as information on HIV in schools and antenatal clinics.
