Please go for English language editing as there are so many grammatical errors elsewhere in the manuscript. Also, write the methodology in detail like an estimation of sample size with formula, prevalence, etc. Please incorporate all the feedback given.

This study covers a very important area yet, while going through the study, it has been found that there are so many errors in writing so please consult with a proficient English language expert to edit this manuscript grammatically.

Please go for the language editing (minor) once again as advised. Address the feedback given appropriately e.g. Nambia has been written twice but Cameroon is not mentioned at all in the abstract and results sections (pie chart).
