Background: COVID-19 is a pandemic disease begins on 11March, 2020; it was growing internationally. Pregnancy suppresses the immune system, making pregnant women more vulnerable to COVID-19 infection and severe sickness. To avoid becoming infected with the virus, extreme awareness is advised. Knowledge of the condition and one's attitude toward it both play a role in one's willingness to embrace public health interventions. Aim: Was to assess the knowledge, attitude and practice toward corona virus infection among pregnant women attending antenatal care clinics at Kafrelsheikh Hospitals, Egypt. Subjects and method: Design: Descriptive research design was utilized in this study. This study was conducted at antenatal care Clinics at Kafrelsheikh General and University Hospitals, Egypt. Subjects: A convenient sample of 415 pregnant was included in this study. Tools: The data were collected using four tools. Tool 1: Socio-demographic structured interview schedule Tool II: The pregnant woman's knowledge about COVID-19 infection assessment questionnaire. Tool III: The pregnant woman's attitude toward COVID-19 infection assessment questionnaire. Tool IV: The pregnant woman's practice of COVID-19 preventive measures questionnaire: Results: According to current study, more than twothirds (75.4 percent; 95 percent and 43.6 percent of pregnant women respectively) had good knowledge, positive attitude, and excellent practice concerning the coronavirus pandemic. Studied women according to the factors related to their knowledge of coronavirus infection 2.99 revealed that, (1.7-5.0) and 1.6 (1.2-2.7) respectively were found to be more likely to have good knowledge among pregnant women who had completed secondary school or above and lived in urban area. AOR = 1.7 (1.2-2.6) and 2.3 (1.3-4.0) respectively for good practice of preventive measures were maternal age of 25 years and being an urban resident. Conclusion: The target population had good knowledge, excellent practice, and positive attitude towards COVID-19. Recommendations: Pregnant women from isolated areas as well as those with lower levels of education should be educated, and legal enforcement should be established to improve the implementation of covid-19 preventive measures.

The research began on March 7, 2021, as the regions of Ain Al-Wusta and Ain Jarura were chosen to take soil samples. The sulfuric water was treated using laboratory batch reactors. Locally manufactured glass tubes were used, with dimensions 17 * 17 * 55 in length, width and height, respectively, Subsequently, microbiological and chemical analyzes of the soil were performed. The results of the study showed success of the physical treatment process that was used to reduce the levels of sulfur in the water Depending on the source of water and the type of material used, the triple-magnetic treatment achieved the highest removal rate of 73% in Ain Al-Wusta soil, 40% in soil sample B1, and 27% in soil sample B2 of Ain Jarura. The results of bacterial culture showed that Gram-negative bacteria were dominant by 100% in soil samples from Ain Jarura region treated with untreated sulfuric water (WA1, WA2, WA3) (Table- 4), as well as for the same soil samples treated with sulfuric water treated with sand filter (GB1), charcoal filter (GB2) and magnetic field filter. (GB3) Soil samples treated with untreated sulfur water were dominated by Pseudomonas aeruginosa with a percentage of 66.7% and Acinetobacter lwoffii with a percentage of 33.3%.The results of the bacterial count of soil samples from the Ain Jarura region showed that there were significant differences between the bacterial number with sulfuric water treated with the three filters, As for soil samples from Ain Al-Wusta region, only soil samples added to sulfuric water treated with charcoal filter (WB2) gave significant differences with a significant decrease of number (84×102 CFU) for the species Aerococcus viridans. The results of the antibiotic sensitivity test showed that Elizabethkingia meningoseptica gave the highest rate of resistance to antibiotics about 66%. The results of the study showed that the resistance of bacterial isolates to antibiotics did not show significant differences between soil samples treated with treated and untreated sulfur water, except for the GB2 isolate.
