There are 20 new community cases today. 19 of these are household or known
contacts and only one of these remains unlinked. Interviews are underway with
that person to determine how they are linked to the current outbreak. As
noted yesterday, we are expecting some fluctuations in case numbers at this
point in the outbreak.
(新闻稿第一段，今天+20中有19位是已知且清楚的感染源，剩下一位不明疫调中)

Subcluster reporting (衍生群聚报告)
A number of clusters are no longer cause for concern as we are not seeing new
positive cases within them. Each cluster that remains of interest, could be
considered as a big bubble with the majority being close-knit groups of
households There has been good communication and engagement with these groups
of households.
Additional reporting will now include the number of subclusters that are
active, contained, dormant or closed, based on the time since the last case
associated with the subcluster was reported, and factors like whether the
case was a household member. This helps us determine the risk associated with
each subcluster.
之后的报告会提供一些新的资料像是群聚的状况
包含新病例跟群聚目前最近数位确诊者的关联性，可以看出群聚目前的风险
Active subclusters:
Cases reported within the previous 14 days and
are not household or other known contacts of previous cases
Contained subclusters:
Cases reported within the previous 14 days and
are household or other known contacts of previous cases
