Study design and period
This study was questionnaire based cross-sectional study carried out for four months (November to February 2021).
Study Area
Injibera was the administrative center of Agew Awi Zone, which is located in Amhara regional state Bahir Dar City 113km and 447 km from Addis Ababa from Ethiopia. Formerly the name Injibera was the name of small village towns around Kosober meaning “Koso tree” the name given by Emperor Haile Selassie during the Italian attack on Ethiopia. Today, Injibera was dominated the name of Kosober and Capital City of Agew nations Awi Zone in A. Injibera was the richest in cultural heritage and tourism specially Horse ride in cultural celebration during December to the end of March and the Agew Horse Association in 1933E.C, 81th celebration conducted in Injibera after Adwa victory in Ethiopia.
Study Population and sample
All Injibera males and females was investigated in the study. All those who met the inclusion criteria were included.
Inclusion criteria
All Injibera males and females in Injibera during the study period with simple random sampling was included.
Exclusion criteria
All males and females not meeting the inclusion criteria were excluded.
Data collection
Since, primary source of data collection used to collect raw data from respondents through personal interview and closed ended questionnaires in Injibera.
Variables
The dependent variable was challenges in control COVID-19 (low, medium and high). The predictor variables were Education level (Illiteracy, Student, Diploma and Degree and above), Social media (Facebook, Television, Community, Radio, SMS, Twitter and Others), Racism (Black to White, Language differences, Country to country and Continent to Continent), Job types (Agriculture, Merchant , Civil servant, Teacher, Banker, Driver, Politician and Others), Housing status (rented, owned, others ), Residence (Urban, Rural), Religion (Orthodox, Muslim, Protestant, Others), Influence (Health status, Political, Social, Economical), Households size(Zero, between 1-5, more than 5), Awareness (Poor, low, medium, high, very high),and Access(No, Yes).
Sampling Design and Techniques
The sampling method used in this study was simple random sampling procedure. The study used the cross-sectional sample design to determine the challenges of in control COVID-19 in Injibera.
Sample size determination
According to the 2007 national census conducted by the central statistical agency of Ethiopia, Injibera has an estimated total population of 21,065 of whom 10,596 are males and 10,469 are females. The sample size for this study was determined based on simple random sampling at 95% confidence level. The sample size formula is given by[13]

Data entry and Analysis
After the data collected, the next step is edited, analyzed and summarized the data in appropriate manner and the available data would be transformed in to reliable and useful information with the help of statistical analysis procedure by using SPSS version 25. Descriptive statistics is to provide over view of the information collected. It was used during the frequency, percentage, and table. Inferential statistics was making inference or conclusion about population, estimation was chi-square test and ordinal logistic regression model.
Chi-square test of association
The variable chi-square cannot be negative then, the curve do not extended to the left of zero[14]. The variables in chi-square distribution must be nominal or ordinal scale of measurements[15]. The significance of α in chi-square test is right tailed areas of the chi-square distribution[15]. In this statistical procedure there is relationship between categorical variables or not[15].
Ordinal logistic regression
The outcome variable can be grouped into two categories-multinomial and ordinal[16]. When the outcome variable is classified in a certain order, it is not possible to use the multinomial logistic regression model[16]. In such a case, ordinal logistic regression models have been used to analyze ordinal response variables. Moreover, when there is a need to consider several factors, special multivariate analysis for ordinal data is the natural alternative[16]. Ordinal logistic regression models have been widely applied in most investigation[16]. The commonly used ordinal logistic regression model is the constrained cumulative logit model[16].
Cumulative logit model
Ordinal logistic regression refers to the case where the dependent variable has an order[16]. The most common ordinal logistic model is the proportional odds model, also called cumulative probabilities of the response categories[17]. If we pretend that the dependent variable is recorded as ordinal having categories, then the application of ordinal logistic model is the appropriate method. An attempt to extend the logistic regression model for binary responses to allow for ordinal responses has often involved modeling the cumulative logit[17].
