Cases rose 38% in the week before the prime minister’s decision not to ease restrictions.
However, the vaccination program is starting to reach its final stages, as adolescents in parts of Kent are asked to book their vaccines and all will be invited from tomorrow.
Across the county, 590 new cases were recorded in the week ending June 12, an increase of 38.2% bringing the infection rate to 31.72.
Only two regions saw cases drop last week – Dartford (-5.2%) and Canterbury (-21.4%).
Gravesham now has the highest infection rate after cases rose 103.6% to 53.3.
Two deaths have been recorded so far in the county in June.
Thanet has the lowest infection rate at 12.7, although cases have doubled in the region over the past week.
Due to this increase and concerns over the spread of the Delta variant first detected in India, the easing of restrictions was postponed until June 19 earlier this week.
Delta cases have increased nearly 70% in western Kent, but are down on the other side of the county.
The latest figures show there were 202 new cases of the strain in the region in the week to June 4, an increase of 53.
Most of the cases have been found in Medway (53) and Dartford (37).
While it’s not all bad news, Kent’s over-21s are being called upon to reserve their jabs as the final leg of the program approaches.
Those over 18 in Whitstable are also being called upon to book jabs and two new walk-in Covid jab clinics will be operational this weekend with the aim of vaccinating thousands over 18 in Canterbury.
Eight of Kent’s 13 regions now have 80% of their population vaccinated with the first dose.
Thanet remains the area with the most first doses given to 84% of people – sitting above the Kent average of 79%.
Canterbury vaccinated the lowest percentage of its population with 72% of people receiving their first dose.
Six regions of Kent gave more than 60% of their population the second dose of the vaccine, Thanet, Folkestone and Hythe giving the most at 66%.
Overall, the number of vaccines distributed is down this week after a significant drop in second doses distributed.
During the week ending June 13, 35,511 first doses and 55,131 second doses were administered, bringing the total to 90,642.
This is a decrease from 104,585 the previous week, when 23,423 first doses and 81,162 second doses were administered.
The total number of people fully vaccinated in Kent now stands at 847,234.
