Via the Centre for Health Protection: Heightened vigilance warranted under persistently high scarlet fever activity. Excerpt:
The Centre for Health Protection (CHP) of the Department of Health today (March 21) appealed to parents, schools/institutions and healthcare professionals for heightened vigilance against scarlet fever (SF) as its activity has been increasing in the past few weeks.
According to the CHP's surveillance data, the weekly number of SF cases increased from 41 in the week of February 26, 2017, to 49 and 59 in the two subsequent weeks. Regarding SF outbreaks in schools/institutions, six affecting 12 pupils/children were recorded in the last three weeks.
"The local SF activity is usually higher from November to February and from June to July. Of note, after the seasonal peak from December 2016 to January 2017, the SF activity increased again in the last few weeks and was higher than that in the same period in previous years. Parents should take extra care of their children in maintaining strict personal, hand and environmental hygiene," a spokesman for the CHP said.
As of March 18, a total of 474 SF cases had been reported to the CHP in 2017, comprising 286 males and 188 females aged from 2 months to 31 years, nearly all of which (465, 98 per cent) were under 10. Most presented with mild illnesses and clinical presentations were largely similar to cases in previous years. Among them, 170 cases (36 per cent) have required hospitalisation. No severe cases requiring admission to an intensive care unit or deaths have been recorded so far.
"We will issue letters to doctors, hospitals, schools and institutions to alert them to the latest situation. Schools should promptly report to the CHP in case of an increase in respiratory illnesses or absentees for immediate epidemiological investigations and outbreak control," the spokesman said.
SF is a bacterial infection caused by Group A Streptococcus. It mostly affects children. It is transmitted through either respiratory droplets or direct contact with infected respiratory secretions.
