Introduction: During pregnancy, many physiological, anatomical, biochemical, and immunological changes and adaptations happen within the mother. These changes and adaptations lead to minor discomforts1. During the COVID-19 pandemic, the health services such as immunization, ANC, and other essential services for pregnant women and children were adversely affected. Over this period, the mortality numbers would, thus, expectedly have gone up. What is required is that the government, with the help of this useful data and analysis, undertakes steps that help the situation at the district and subdistrict level. Reveling in aggregate numbers will not help solve the problem2. Objective 1. To assess the pre-test level of knowledge score regarding minor disorder of pregnancy among antenatal mother in selected village of Sasaram Rohtas. 2. To assess the post-test level of knowledge score regarding minor disorders of pregnancy among antenatal mother in selected village of Sasaram Rohtas. 3. To find out the association between score with their selected demographical variables. Methodology: The current study was a pre-experimental one group pre-test and post test research study among the ante natal mothers at the selected village the total sample size was consists 30 mothers were selected by using purposive sampling technique. The researcher was using the semi-structured questionnaire to collect the data. Data was collected using a self structured questioner. After collection of data, the data was analyzed by using inferential statistics such as chi-square and paired "t" test to determine association between pre-test and selected demographic variable among ante-natal mothers. Result: The currents study results shows out of 30 study participants that the highly majority of 80% of mothers had average knowledge, 20% of mothers had poor knowledge and 0% of mothers had excellent knowledge during the pre-test knowledge score. After the planned teaching programme differently changed the mother's knowledge, whereas the post-test knowledge score majority of 70% of mothers had excellent knowledge, 20% of mothers had average knowledge regarding the prevention of minor aliments during the antenatal mothers. The mean post-test knowledge score ranged from 7-18 (df-11) which is higher than the pre-test knowledge score of 3-12(df-18). The mean post-test knowledge score (of 12.52.94) was higher than the pre-test knowledge score (6.672.69). The paired "t" value comparison was 7.39 while df 29 and the p-value for this comparison was significant (0.000) which is less than the normal p-value (<0.05). Discussion and Conclusion: It can be inferred that the structured teaching programme was proved significantly highly effective in improving the knowledge of mother's antenatal mother regarding prevention of minor aliments disorder. Mean post-test knowledge score ranged from 7-18 (df-11) which is higher than the pre-test knowledge score of 3-12(df-18). The mean post-test knowledge score (of 12.52.94) was higher than the pre-test knowledge score (6.6...
