Object ives: The aims o f this study was to evaluate the fluoride content of bottled drinking water co mmercially available in Fiji in March 2006; and to report on the labelling of fluoride concentrations. Methods and Materials: Co mmercially available bottled water in Fiji, in March 2006 was purchased fro m supermarkets. Three bottles of 11 brands were purchased. Ten millilitres of each water sample was mixed with 2 millilit res of spands reagent; these were then tested for fluoride concentrations using photo spectrometry at wavelength of 580 nano metres. The fluoride concentrations listed on the sample labels were also noted and compared with the results obtained fro m the spectrometry test. Results: The mean (±standard deviation) of fluoride was 0.09 (±0.05) pp m. None of the brands tested labelled the fluoride concentration in the bottled water. The range of fluoride concentration was between 0.02 to 0.34 pp m. There was also a vast variation of fluoride concentrations within the same brand of product. Conclusions: Co mmercially available bottled drin king waters in Fiji contain a wide range of concentrations of fluoride and none of the manufacturers labelled the content of fluoride on the bottle. It was also noted that none of the brands contained optimal levels of fluoride.

: The COVID19 pandemic is raging across the globe with the total active cases increasing each day. Globally over 63 million COVID-19cases and more than 1.4 million deaths have been reported to WHO. Throughout the world academicians, clinicians and scientists are working tirelessly on developing treatment to combat this pandemic. Origin of novel SARS-COV-2 virus still remain foggy but is believed to have originated from a bat coronavirus RaTG13 with which it shares approximately 96% sequence similarity. In the present review, authors have provide an overview of the COVID-19 pandemic, epidemiology, transmission, developments related to diagnosis, drugs and vaccines along with the genetic diversity and lifecycle of the SARS CoV2 based on the current studies and information available.
