Knowledge, Attitudes, and Practices (KAP) Towards COVID-19: An Online Cross-Sectional Survey of Tanzanian Residents .

Background The Corona Virus Disease -19 (COVID-19) pandemic is a global health emergency that requires the adoption of unprecedented measures to control its rapid spread. Tanzanians' adherence to control measures is affected by their knowledge, attitudes, and practices (KAP) towards the disease. This study was carried out to investigate knowledge, attitudes and practices towards COVID-19 among residents in Tanzania during the April – May 2020 period of the epidemic. Methods This cross-sectional study analyzes responses of self-selected Tanzanians who responded to an invitation to complete an online questionnaire. Survey Monkey tool was used to develop the questionnaire used for data collection. The survey assessed demographic characteristics of participants as well as their knowledge, attitudes, and practices toward COVID-19. A Chi-square analysis was used to compare proportions. Analysis of variance (ANOVA) was used to determine differences among age groups, whereas results were considered significant if the p-value was <0.05


INTRODUCTION
Coronavirus disease 2019 (COVID- 19) is a disease caused by a novel coronavirus that was first detected in December 2019 in Wuhan, China.It is characterized by sudden onset, fever, fatigue dry cough, myalgia, and dyspnea.Data show that 10-20% of the patients develop severe cases, which are characterized by acute respiratory distress syndrome, septic shock, difficult-to-tackle metabolic acidosis, and bleeding and coagulation dysfunction [1,2].World Health Organization (WHO) declared it a public health emergency of international concern and has called for collaborative efforts to prevent its rapid spread [5].Although clinical data have shown the overall case fatality rate of COVID-19 ranges 2-5% worldwide, which is much lower than those of Severe Acute Respiratory Syndrome (SARS) (9.5%), MERS (34.4%), and H7N9 (39.0%), pathogens continue to emerge and spread to the population at risk.The threat of more contagious and virulent variants demands public health actions to move from purely treatment activities to preventive measures practiced by the public [1][2][3].The ongoing COVID-19 pandemic has spread very quickly, and to date at the time of the survey, the virus had reached over 200 countries altogether, resulting in 236,368,875 laboratory-confirmed infections and 4,826,358deaths [4].
Tanzania is among African countries that have been affected by the COVID-19 pandemic [6].Until April 24, 2021 government authorities announced only 284 cases of COVID-19, among them 256 were in stable condition, seven in special care, 37 recovery, and 10 deaths [7].Dares-salaam City and Zanzibar Island have the highest number of cases.Other regions affected were Mwanza, Dodoma, Pwani, Kagera, Manyara, and Morogoro [8].Several measures have been adopted to control COVID-19 transmission in Tanzania, including closing all schools and universities, observing physical distancing, prohibiting mass gatherings, isolating suspected cases, and caring for confirmed and suspected cases.Moreover, Tanzania residents were obliged to perform handwashing with soap and running water or alcohol-based hand sanitizer and urged to wear face masks outside their homes.
To effectively control COVID-19 in Tanzania., individuals' adherence to these control measures is essential [9][10].Reports from different outbreaks recommend that knowledge and attitudes towards infectious disease can sometimes result in a level of panic among the population and complicate endeavors to prevent the spread of the disease [9][10][11][12].
There is an urgent need to understand the public's awareness of COVID-19 in Tanzania to facilitate outbreak management of COVID-19.This study was carried out to investigate knowledge, attitudes, and practices (KAP) towards COVID-19 among residents in Tanzania during the March -April 2020 period of the pandemic.

Study design
This cross-sectional survey took place from 15 th -28 th of April 2020.

Sample size and selection
Participants were self-selected when they choose to answer the questionnaire.A total of 5,000 residents were assumed to actively use media connections.Calculation using statistical software gave a minimum sample of 384 [13].To adjust for non-responders 400 residents conveniently receive the link with the Questionnaire [14].

Data collection
Due to the infectious nature of disease transmission, online survey forms were used to collect the data.Survey Monkey tool was used to develop a link and KAP questionnaire for data collection.
The questionnaire consisting of 20 questions was were prepared by following WHO guide for KAP questionnaire development.This template was modified and adapted to the Swahili language.It was then validated and piloted according to guidelines for clinical and community management of COVID-19 by the Tanzanian Ministry of Health Community Development, Gender, Elderly and Children.Demographic variables included age, gender, and education Level.There were 17 KAP questions regarding clinical presentations, transmission routes, and control of COVID-19.These questions were answered either as Yes/No, true/false, and "I don't know".The total score ranged from 0 to 17, with a higher score indicating a better knowledge of COVID-19.Participants could provide only one response per question.The reliability of the knowledge, attitude, and practice questionnaires was checked and the values of Cronbach's alpha were 0.81, 0.88, and 0.86 respectively, indicating acceptable internal consistency.

Data analysis
Response data were recoded and analyzed using SPSS 17. Results were considered significant if the p-value was <0.05.

Socio-demographic characteristics of the study population
A total of 400 participants completed the survey.The range of the age of the participants was 18 to 75 years, and the mean (SD) was 32 (10.3) years.Women represented 54% of the participants.Majority of the participants (n=242, 60.3%) had a bachelor's degree or above.Participant socio-demographic characteristics are given in Table 1.

Knowledge regarding COVID-19
Overall, 84.4% of the participants scored above the mean.The range of correct answers was two to ten the mean (SD) score was 9.3 (2.0), and the median was nine.A score above nine was considered a good knowledge level.60.5% of the degree holder score above 9, Figure 1.The range of percent of correct answers was 70.2-98.6%(Table2).The mean (SD) score was 8.7 (1.6).Results varied between genders and among age groups and education levels (P<0.001).Males, age group of 16-29 years, with a bachelor's degree or lower were significantly associated with lower knowledge score Table 2.

Attitudes and Practices Regarding COVID-19
The majority of the respondents agreed that COVID-19 would be successfully controlled (n=384, 96%).The attitude towards the final success in controlling COVID-19 had no significant differences across genders and education levels (P<0.71).The majority of the participants had not visited crowded places (n=308, 77.0%) and wore masks when going out (n=352, 80.0%) in recent days.Almost all participants (n=392, 98.0%) correctly identified that COVID-19 is transmitted through respiratory droplets and that factors such as chronic illnesses and obesity can lead to a serious morbidity (Figure 1).

DISCUSSION
This is the first online cross-sectional study examining KAP towards COVID-19 among Tanzania residents.In this study, 84.4% of the participants had a good knowledge of COVID-19, which is comparable with a study conducted in China where more than seventy percent of study participants had good knowledge.Previous studies from different countries have identified good knowledge in infection control as a predictor of good practice [17,18].These studies also highlighted that major gaps in disease knowledge could result in uncertainties and nonstringent control measures [19].
Most of the participants had confidence that COVID-19 will be contained and had a certainty that we can win the fight against the disease.This attitude could have attributed to positive practice with majority reporting not visiting crowded places and wearing masks whenever they go out of their homes.Furthermore, nearly all reported adhering to preventive measures as instructed by their national health care authority.The findings are useful for policy makers to consider the need for a comprehensive specific group target health education program for COVID-19 prevention and control.
The finding of a high level of knowledge among residents is a good predictor of positive impact initiative to involve the community in a fight for COVID-19.However, the results may have been affected by the convenience sampling method used.The majority of participants (n=278, 69.5%) held a secondary degree or higher, and all participants had access to the internet.These are the privileged group who would actively seek information of this infectious disease from various channels of information, including the official website of the Ministry, and the WhatsApp account.The same study should be conducted among vulnerable populations or underprivileged communities.
The strength of this study lies in its large sample recruited during a peak of the COVID-19 outbreak.Nevertheless, compared to the population statistics, our sampling method picked middle and high economic societies, we speculate that knowledge might have been over overestimated and attitude and practice underestimated.Community based national cross-sectional study is recommended when an outbreak is over.

CONCLUSIONS
Our findings emphasize the need to investigate the KAP towards COVID-19 among Tanzania residents of low socioeconomic status.This will encourage an optimistic attitude and maintaining safe practices.Community-based health education programs about COVID-19 are likely to be helpful and necessary approach to control the disease.
