The rate of cases for Walsall per 100,000 is up from 415 to 826 in the last week.
Stephen Gunther, director of Public Health Walsall said: “With the rapidly increasing rate that we are seeing in the borough, the danger is very real.
"The only way that we can get these rates down is for you to stay at home.”
“Get tested the moment you experience symptoms, even if they seem very mild, or if you are advised to get tested by the NHS.
"Anyone with Covid-19 symptoms or a positive test result must stay at home for the full isolation period.”
“With an average of just under 300 people in Walsall testing positive every day this year, and one in three people not showing symptoms it is getting easier and easier to catch Covid-19.
"The safest thing to do is stay home until we can get the numbers down.
“The vaccine will help enormously, but the virus is spreading faster than we can deliver the vaccine and we need to catch up.”
“If you have to go out, be more careful than ever that you are following Hands, Face, Space guidance: Act like you’ve already got it: don’t catch Covid and don’t pass it on to someone else.”
Councillor Stephen Craddock, Portfolio Holder for health and wellbeing, Walsall Council said: “Please stay at home and make sure you get tested if you experience symptoms, no matter how mild.
“Support is available for anyone who tests positive and/or is self-isolating and therefore cannot work, it is far more important that you get tested, even if you don’t feel too bad.
“This will prevent the virus from spreading and help to protect your loved ones.”
