The weekly total of cases is now over 25 per 100,000 inhabitants, which places the district above the threshold to be placed on orange alert on the government watch list for local intervention.
Data released this afternoon gives infection rates through Tuesday, August 25, as there is a 3-4 day delay for cases to be fully reported.
In the week ending August 25, there were 60 positive coronavirus tests at Trafford, 13 more than the week before – a 28% increase.
This brings the weekly infection rate per 100,000 population to 25.3 and provisional data shows it will increase by a few points tomorrow to over 28.
A total of 32 more cases were announced to Trafford in the past two days, compared to 15 cases announced Thursday and Friday last week.
Trafford is the only borough in Greater Manchester to show a week-over-week increase in cases of this magnitude.
Cases have increased slightly in Wigan where local restrictions were lifted on Wednesday this week, but the infection rate remains low there.
Stockport and Bolton, the other two areas where local restrictions were lifted today, continued to show a downward trend in the spread of the virus, although it stabilized slightly in Bolton.
Oldham continues to have the highest infection rate in Greater Manchester, but the number of cases is declining faster in Oldham than in any other borough in the region.
Infection rates in Manchester, Rochdale, Bury, Salford and Tameside are also down slightly week on week.
Local restrictions were announced in Greater Manchester on July 30 after infection rates showed an upward trend from mid-July.

Data from the past two days suggests that the downtrend is leveling off and that there has been a slight increase in the number of reported cases, but it is too early to say if this will develop into another uptrend.
