The Queen has expressed concern that malaria is not getting enough attention due to the Ebola outbreak, a medical professor has said.
Accompanied by the Duke of Edinburgh, the Queen was visiting foreign affairs think tank Chatham House in central London last night to launch a new leadership academy.
She met with Professor David Heymann, professor of infectious disease epidemiology at the London School of Hygiene and Tropical Medicine.
According to him, she said: "After Ebola we will still have malaria."
He added: "She was very interested in Ebola because she said her doctor had told her that there were more people dying from malaria every week than are dying from Ebola - and he was right.
"She's afraid that malaria will have a comeback because of the fact people are not paying enough attention to it."
Prof Heymann said the Queen is correct because children with fever will have trouble being seen due to hospitals being occupied with Ebola sufferers.
He said there is "a great fear" that there will be an increase in deaths from common childhood diseases like malaria and diarrhoeal diseases.
He described the Queen as "very perceptive".
He added: "This should not detract attention from Ebola. It's a very terrible disease.
"But on the other hand what the Queen has done is call attention to other infectious diseases."
He added: "She asked a very piercing and important question which means that she has analysed clearly the world situation of disease and she's come to this conclusion which is the right conclusion."
A royal source said: "She was concerned that efforts to address Ebola should not detract from work to combat other health threats in West Africa."
During her visit, the Queen removed a brick from the wall between Chatham House - the Royal Institute of International Affairs - and neighbouring Ames House to symbolise the expansion next door.
The institute said it was creating The Queen Elizabeth II Academy for Leadership in International Affairs to offer leaders the chance to develop skills to deal with major policy challenges and the critical issues facing the world.
Before unveiling a plaque to mark the occasion, the Queen, wearing a light green skirt and jacket, said: "I am delighted that the Royal Institute of International Affairs had launched this academy as it approaches its first centenary anniversary. I wish the institute every success for this new initiative."
The Queen has been patron of the Royal Institute of International Affairs since 1952.
In 2006, she listened to a debate at the institute under the famous Chatham House Rule which means the identity and affiliation of the speakers and participants cannot be revealed or reported in a bid to aid free discussion.
