A pastor and father-of-five is among those to have died after contracting Covid-19.
Charles Kayiwa, 59, died in hospital on Sunday, less than a week after being admitted. He was a preacher with Alpha and Omega UK ministries, affiliated with Elim Pentecostal church.
One friend wrote on a Facebook page in his memory: "May the almighty God comfort your wife and children because only God knows it all. You have fought a good fight."
Another wrote: "I will miss your jokes, funs and smiles but I know you are with the Lord and I pray that your soul rest in peace, in Jesus' mighty name Amen."
His brother, Danny Male, from Tottenham, north London, told the PA news agency he was a "normal, fit guy" and had no underlying health issues.
He said: "He was a fantastic guy, very smiley and jokey.
"Some of us are not, say, Christian types, but he was always spreading positivity, talking about God, being happy and bringing brightness to people's lives.
"He was a very nice guy, and very popular."
Mr Kayiwa, originally from Uganda and known to friends as "Paddy", moved to the UK in 1993 having spent seven years living in Sweden working with a Christian fellowship in Gothenburg.
He was one of ten siblings, and enjoyed hobbies such as ice skating and going on jet skis, his brother said.
He was well known among the Ugandan community in London, particularly in the Charlton area where he preached.
Mr Male, 50, said: "The disease took him so quickly. He was admitted to hospital on Monday and by Sunday he was gone.
"I will miss him a lot - he was such a good guy."
His funeral will be on 15th April with people watching via video link while ten people are allowed to attend the burial.
