Coronavirus antibody positive tests and continued use of personal protective equipment throughout the pandemic.
The COVID-19 pandemic has thrust not only a novel virus onto the world, but new challenges resulting in novel approaches. Governments have reduced regulation in order to facilitate timely advances to combat the disease. ⋯ Mask use has come to the forefront and human factor (HF) strategies must be examined to reduce risk associated with lack of engagement from both healthcare staff and patients. In this we explore these issues and suggest some solutions.

The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected more than 6 million people globally; and changed the dynamics of the entire world. In March 2020, novel coronavirus disease 2019 (COVID-19) was declared as a pandemic by the World Health Organization (WHO). In Pakistan, the first case of COVID-19 was reported on 26th February, 2020. ⋯ In the scenario of a lockdown, dental students are suffering a lot and the dental colleges and faculties must try their best to overcome this situation.

On 30th January 2020, an outbreak of atypical pneumonia caused by a novel betacoronavirus, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was declared a public health emergency of international concern by the World Health Organization. For this reason, a detailed evolutionary analysis of SARS-CoV-2 strains currently circulating in different geographic regions of the world was performed. A compositional analysis as well as a Bayesian coalescent analysis of complete genome sequences of SARS-CoV-2 strains recently isolated in Europe, North America, South America, and Asia was performed. ⋯ A significant migration rate per genetic lineage per year from Europe to South America was also observed. The results of these studies revealed an increasing diversification of SARS-CoV-2 strains. High evolutionary rates and fast population growth characterizes the population dynamics of SARS-CoV-2 strains.
