'Antiseptic throat spray, malaria drug may curb COVID spread'

SINGAPORE: Using a type of antiseptic throat spray, and an oral drug used to treat malaria and arthritis, have been found effective in curbing the spread of coronavirus, according to a new study.

The six-week long study, led by researchers from the National University Hospital (NUH) in Singapore, involved more than 3,000 migrant workers from India, Bangladesh, China and Myanmar living in Tuas South dormitory, the Channel News Asia reported.

The results showed that among those who used throat spray thrice a day, only 46 per cent contracted the disease. This is compared to 49 per cent among those who took hydroxychloroquine and 70 per cent who took vitamin C.

The two drugs were chosen because they are easily available, said Seet, adding that they protect the throat, the "key entry" for viruses.

"We concluded that povidone-iodine throat spray was associated with a statistically significant reduction in infection by an absolute risk of reduction of 24 per cent while oral hydroxychloroquine was associated with a statistically significant reduction in infection by an absolute risk of reduction of 21 per cent," lead author Raymond Seet, Associate Professor at the NUH was quoted as saying.

However, the researchers stressed that the drugs are not meant to be used for COVID-19 prevention in the general community if it is a lower-risk setting, the report said. (IANS)
