Introduction: This study aimed to determine the prevalence of COVID-19 among healthcare workers; to describe the means of prevention used by these nursing staff and to determine the behavior and attitude towards the disease of these nursing staff of the University Clinics of Lubumbashi. Methods: This is a descriptive cross-sectional study from January 1, 2021 to June 31, 2021 among all healthcare providers (doctors and nurses) working at the University Clinics of Lubumbashi. Results: Out of 391 caregivers surveyed, including 246 doctors and 145 nurses, we observed a prevalence of 10.99% that is 43 caregivers, including 28 doctors, ie 65.12% and 15 Nurses or 34.88% whose average age was 40 ±6 years, with a predominance of men (56%) that is sex ratio of 1.26 in favor of men. It is important to note that most cases were diagnosed clinically, ie 62.79% of cases. The saliva droplets were themode of infection of COVID-19 the most experienced by caregivers with 58.14%, followed by physical contact with a rate of 39.53%. The wearing ofmask and hydro-alcoholic friction were the most cited by caregivers as the most effective means of prevention, which they applied and advised patients. Most of the caregivers were subjected to chloroquine and azythromycin, the others admitted to using the traditional treatment of inhaling the vapors of several wild leaves and trees, in particular: lemon, mango... is about the outcome of the disease, almost -all of the nursing staff were cured, ie 97.67% of cases. Conclusion : The prevalence of COVID-19 disease among caregivers was 10.99%, however it is observed that active screening was not carried out and the cases observed presented almost all of the clinical signs and the clinical diagnosis was used for all cases, hence its underestimation. It would be important to regularly screen exposed caregivers and make personal protective equipment regularly available and monitor barrier measures.

Introduction: In Africa, up to 20% of women who have had a caesarean section contract a nosocomial infection of surgical wounds, compromising their health and ability to care for their children. In the DRC the field of hospital hygiene is of little interest to researchers, so it is difficult to analyze the problem when it is a thorny public health problem. Methods: We conducted a cross-sectional study whose study population consisted of women, whose delivery was associated with surgery, including a caesarean section or an episiotomy. The data collection was exhaustive and one nosocomial case of surgical wounds was defined according to the WHO definition. Associated factors were evaluated by the prevalence ratio at the significance level p ˂ 0.05. Results: We obtained 443 surgical cases; of which 253 were caesarean sections 57.1% and 190 or 42.9% were episiotomies and the prevalence of nosocomial surgical wound infections was 9.9%. The risk of developing a nosocomial surgical site infection was 6.8 times high at the Congo Railroad Hospital (SNCC) and 5.0 times at Jason Sendwe General Referral Hospital than at the Hospital. The GeneralReference Hospital (HGR) of Kenya and its association were statistically significant (p = 0.0022). A statistically significant difference was observed between the rate of nosocomial infections of surgical wounds and the age group of pregnancy between 32 to 34 WS, parturient who gave birth in this age group was 4 times at the risk of developing nosocomial infection surgical wounds. Long stay of more than 10 days (p=0.0010), delivery by caesarean section (p=0.0481), parturient carrying the indwelling catheter (p = 0.0162) and taking antibiotics were associated with the onset of nosocomial infection of surgical wounds. Conclusion: The factors associated with nosocomial infections of surgical wounds in maternity wards of public hospitals in Lubumbashi are related to the state of the structures, to the health care administered to clients. It is necessary to improve the hygiene conditions of the maternities, to train the personnel on the measures of hygiene and to apply a good policy of use of the antibacterial ones.
