THE FATE OF ROTAVIRUS IN SEAWATER
AND REMOVAL BY SEWAGE TREATMENT
Rotavirus is recognised as a major cause of severe infantile diarrhoea and can also cause gastroenteritis in adults. Sea outfalls are currently designed to meet bacterial, rather than viral, standards. In order to improve the effectiveness of sewage treatment and disposal, more information is needed on the fate and inactivation of viruses in the sea, and the effectiveness of different means of sewage treatment in removing viruses.
The sediment adsorption experiments need to be repeated using wet sediment or dried sediment which has been rinsed with distilled water to remove concentrated salts. These experiments should be carried out using larger quantities of rotavirus on smaller volumes of sediment.
To improve the detection of rotavirus in sewage, that element of sewage which is toxic to the cell monolayer on which viruses are cultured, needs to be removed. Further work is required to improve the methodology currently available.
V RESUME OF CONTENTS
This report reviews the literature and describes the progress of studies to examine the adsorption of rotavirus onto coarse, medium and fine sediments, and to assess the efficiency of different stages in sewage treatment in removing rotavirus.
