As the COVID-19 pandemic continues, there is growing concordance and persisting conflicts on the virus and the disease process. We discuss limited transmissibility of the virus by asymptomatic and mild cases of COVID-19 patients in Bhutan. We followed up the secondary transmission of SARS-CoV-2 in the contacts of asymptomatic and mild COVID-19 patients in Bhutan. Bhutan had 33 confirmed COVID-19 cases in the country as of May 29, 2020. Of these, 22 (67%) were females. Except the first two cases (American tourists), the rest were Bhutanese living outside the country. The mean age of the Bhutanese patients was 26.3 (range 16–33) years. Close contacts of 27 of the 33 cases were followed up for signs and symptoms and COVID-19 positivity. The first two cases had 73 and 97 primary contacts, respectively, and equal number of secondary contacts (224). From the third case, a mandatory 21-day facility quarantine was instituted, all primary contacts were facility quarantined, and there were no secondary contacts. In total, the 27 cases had 1,095 primary contacts and 448 secondary contacts. Of these, 75 individuals were categorized as definite high-risk contacts. Secondary transmission occurred in seven high-risk contacts. Therefore, the overall secondary transmission was 9.0% (7/75) and 0.6% (7/1,095) among the high-risk and primary contacts, respectively. No transmission occurred in the secondary contacts. In contrast to several reports indicating high transmissibility of SARS-CoV-2 in contacts of confirmed cases, the mostly young, asymptomatic, and mild cases of COVID-19 in Bhutan showed limited secondary transmission.

Attitude of children towards science gained attractiveness among the researchers, mainly to influence students’ science learning, their achievements and participation in science class. Therefore, this study using mixed method examined the effects of parents or guardians involvement on attitude of students towards science, gender, teaching strategies, past achievement and student-teacher relationship and little on classroom environment and school location. A total of 18 students completed a questionnaire developed to examine the factors involving on attitudes of students to science. To further increase the authenticity of the quantitative findings, 11 students through judgmental selection took part in interview. The teaching strategies executed, past achievements, career choices and student-teacher relationship were positively correlated with attitude of students towards science. The study suggests that students attitude towards science can be improved by focusing on aforementioned reasons. Moreover, attitudes towards science higher classes can be improved by offering science only to interested, depending on the performance in previous grades.
