Coronavirus Disease 2019 (COVID-19) ranks third in terms of fatal coronavirus diseases threatening public health, coming after SARS-CoV (severe acute respiratory syndrome coronavirus), and MERS-CoV (Middle East respiratory syndrome coronavirus). SARS-CoV-2 (severe acute respiratory syndrome coronavirus type 2) causes COVID-19. On January 30, 2020, the World Health Organization (WHO) announced that the current outbreak of COVID-19 is the sixth global health emergency. As of December 3, 2020, 64 million people worldwide have been affected by this malaise, and the global economy has experienced a loss of more than $1 trillion. SARS-CoV-2 is a positive-sense single-stranded RNA virus belonging to the Betacoronavirus genus. The high nucleotide sequence identity of SARS-CoV-2 with the BatCoV RaTG13 genome has indicated that bats could be the possible host of SARS-CoV-2. SARS-CoV-2 penetrates the host cell via binding its spike protein to the angiotensin-converting enzyme 2 (ACE2) receptor, which is similar to the mechanisms of SARS-CoV and MERS-CoV. COVID-19 can spread from person to person via respiratory droplets and airborne and contaminated fomites. Moreover, it poses a significant risk to smokers, the elderly, immunocompromised people, and those with preexisting comorbidities. Two main approaches are used to control viral infections, namely, vaccination, and biosecurity. Studies to analyze the antigenicity and immunogenicity of SARS-CoV-2 vaccine candidates are underway, and few vaccines may be available in the near future. In the current situation, the Human Biosecurity Emergency (HBE) may be the only way to cope effectively with the novel SARS-CoV-2 strain. Here, we summarize current knowledge on the origin of COVID-19 as well as its epidemiological relationship with humans and animals, genomic resemblance, immunopathogenesis, clinical-laboratory signs, diagnosis, control and prevention, and treatment. Moreover, we discuss the interventional effects of various nutrients on COVID-19 in detail. However, multiple possibilities are explored to fight COVID-19, and the greatest efforts targeted toward finding an effective vaccine in the near future. Furthermore, antioxidants, polyphenols, and flavonoids, both synthetic and natural, could play a crucial role in the fight against COVID-19.

interactions and achieve manifold developments. The purpose of thestudy was to explore the development of social intelligence duringuniversity years among University students. The study was delimited tofour year under graduate programs Bachelor of Science (BS) students ofUniversity of Sargodha. The cross-sectional study includes the studentsof BS programs 1st semester and 7th semester. Using multi-stagesampling technique, 560 students in total from seven department of theuniversity were selected as the sample. Tromso Social Intelligence Scale(TSIS) with reliability coefficient (Cronbach Alpha) 0.75 was used. Itwas found that overall the development of social intelligence duringuniversity years was at good rate and statistically significant. The urbanand rural backgrounds students and boarder and day scholar studentsreported equal level of social intelligence; whereas male studentsreported higher level of social intelligence than the female students. It isrecommended that the universities may arrange seminars and groupdiscussion to provide social interaction to students. Universityadministration and teachers may arrange co-curricular activities andother social gatherings at inter-departmental and inter-university level.
