Rising Covid rates have prompted a fresh appeal for all adults to be double vaccinated as soon as possible.
Infection rates in both Redcar and Cleveland and Middlesbrough are now both at their highest recorded levels of the pandemic.
The rate in Redcar and Cleveland is now 601 per 100,000 of population, surpassing the previous high of 507 last November.
Soaring numbers of cases have seen the Middlesbrough rate per 100,000 reach 684, surpassing the previous peak of January.
Although the link between infection and hospitalisation has been weakened, admissions to James Cook University Hospital are beginning to rise.
All eligible adults are being urged to get both doses of the Covid vaccination as soon as possible.
Esther Mireku, consultant in public health for Redcar and Cleveland and Middlesbrough, said: "With case numbers as high as they are in our area, we urgently need people to get vaccinated and follow the established guidance on hands-face-space and fresh air.
"It's vital people act cautiously and it's sensible for people to take regular lateral flow tests, especially if they're meeting lots of people they don't live with.
"There remains a significant risk of catching and spreading Covid-19, which is still leading to serious long-term illness and hospital admissions.
"It's vital people get both jabs as soon as they're able to. The NHS is making thousands of walk-in slots available."
Free rapid tests for people without symptoms can be ordered online via www.gov.uk/order-coronavirus-rapid-lateral-flow-tests. They can also be collected from several locations identified on this map: https://maps.test-and-trace.nhs.uk/.
Anyone with any symptoms of Covid-19 should book a free PCR test via 119 or online at www.nhs.uk/coronavirus. They should stay at home with anyone they live with until the result is known. If the test result is positive there is still a requirement to self-isolate for 10 days.
Second doses of the vaccine should be taken at least eight weeks after the first.
