Leaders signed a major commitment to end the global AIDS epidemic in cities by 2030, in line with the Evening Standard Campaign on AIDS.
In a statement signed yesterday during a ceremony at the Standardless AIDS Free City Global Forum, they agreed to "strive to achieve zero HIV infection and AIDS-related deaths."
They renewed the commitment to "mobilize resources", "solve causes" and "join as leaders" to end their help in their cities and meet the UN's 90:90:90 objectives.
The goal is to get at least 90% of HIV-aware people with their status, 90% of those treated and 90% of those treated have "undetectable viral load" – where blood levels are so low that they can not be transmitted.
Signatories included Governor Nairobi Mike Sonko, Regional Commissioner Robb Pitts of Atlanta, Timo Martineau of UNAIDS, and Jose Zunigu, President of the International Association of AIDS Providers.
Representatives of London also signed with Anna Aslett, Director of the Elton John AIDS Foundation.
Mr Sonko said: "It is our commitment to lead by 2030 no more AIDS aid … leaders of different cities must show our commitment the most powerful way.
Mr Pitts said, "Signing the Declaration is a sign of a renewed commitment [appeal] disseminates knowledge, informs the public, and cooperates with the people concerned. You can find out what other people are doing … and that is such an exchange of views that is so important. "
Vicky Hobart, chief medical officer for London, said, "It's great to see so many London partners who have committed themselves to what we are trying to do … London is in a great position to work together as well as to learn from other cities. "
Earlier, Health Minister Matt Hancock has pledged the government to stop new HIV transmissions, not only in London but through England, by 2030.
Minister for International Development, Penny Mordaunt said at the forum: "While the world has made great strides in the fight against HIV and AIDS, we have to step up our efforts. The scope of our ambitions is clear, we all passionately believe we can create a world without AIDS, and I know we're going. "
An all-day forum has been seen by international experts who talk about issues such as combination prevention such as PrEP and self-testing, HIV in the transgender community and drug users, and the use of data and analysis to help the most disadvantaged fight against the epidemic.
The standard AIDSfree campaign, launched in December, ends tomorrow. He narrated the stories of people living with HIV around the world and shared professional commentary on medical developments. All funds earned will go to programs supported by the Elton John AIDS Foundation.
Editor George Osborne said to delegates yesterday: "With your help, we have changed our government policy in this country, and we have raised awareness that this is a global challenge that we can challenge, we encouraged more people to test our most successful campaign at all. "
The events identified will be used to schedule the first Global Fast-Track Cities conference on Barbican in September. With the support of the Mayor of London, it combines 250 cities working to speed up disease response, including HIV and tuberculosis.
Mr Zuniga, who organized the conference, appreciated what had been achieved yesterday: "This forum allows us to celebrate [the cities’] successes, but also to talk without worrying about the challenges we face … We will take lessons from this forum and bring them to other cities. "
Paul Stoffels, Johnson & Johnson's vice-president, who supported the forum, said: "No organization, government or NGO can win the fight against HIV … requires cooperation, sustained effort and increased resources, truly global efforts … I am optimistic that with continued innovation and the kinds of cooperation we have seen here, we can achieve this goal. "
Money raised from public subsidies through an appeal against AIDS will be used to support the Elton John Foundation Foundation's projects in six key cities around the world (London, Nairobi, Atlanta, Kiev, Delhi and Maputo). Through US support, the British government will double public donations of up to £ 2 million to be spent on projects in Maputo and Nairobi.
