Earlier on Saturday, Javid said in a tweet: "I tested positive for Covid. I'm waiting for my PCR result, but thankfully I have had my jabs and symptoms are mild.
"Please make sure you come forward for your vaccine if you haven't already."
Confirming the positive test later in the day, he tweeted: "My positive result has now been confirmed by PCR test, so I will continue to isolate and work from home."
Javid became the Health Secretary following the resignation of his predecessor Matt Hancock last month, reports Xinhua news agency.
Hancock broke Covid-19 social distancing guidelines during an alleged affair with his aide, which reportedly caused an outrage in the country.
