Hertfordshire County Council have issued a statement after three people in the county tested positive for the Covid-19 coronavirus.
The Director of Public Health, Jim McManus said: "These new cases of coronavirus are nothing unexpected. We fully anticipate an increase in numbers which is why our services have planned for, and are ready, for this situation.
"Current evidence indicates that most cases appear to be mild, with patients experiencing flu-like symptoms. Older residents or those with weakened immune systems or long-term conditions may experience more severe symptoms, which is why it is important to help protect ourselves and each other.
"Following Government guidance to take basic hygiene precautions remains the best way of significantly reducing the chances of spreading any virus: sneeze or cough into a tissue, bin it, wash your hands frequently and don’t touch your face unless you’ve just washed your hands. We should do this all day every day as we should for flu.
"Good regular cleaning with normal detergent of surfaces people touch regularly or may cough onto, like door handles and lift buttons, is also sensible. People should log on onto www.gov.uk/coronavirus for the latest advice and information."
Dr David Edwards, Consultant in Health Protection, Public Health England East, said: "Public Health England is contacting people who had close contact with three confirmed cases of COVID-19 that are residents of Hertfordshire. We’re working closely with NHS colleagues in that area as well as Hertfordshire County Council to manage the situation and help reduce the risk of further cases.
"Close contacts will be given health advice about symptoms and emergency contact details to use if they become unwell in the 14 days after contact with the confirmed case. This tried and tested method will ensure we are able to minimise any risk to them and the wider public."
