 Dear colleagues, I'm sorry that I can't be with you in person today, but I'm delighted to have an opportunity to add my voice to yours in support of M Health and the Be Healthy Be Mobile initiative. At Public Health England, we think mobile and digital health could transform the field of public health, and we want to play our part in promoting it so it can deliver its full potential. In fact, it's already happening. For example, we've got evidence that SMS texts are an effective way to help people quit smoking. We've also got evidence that sending SMS reminders for screening appointments can help increase attendance. Now, I've used these two examples because they're a reflection of two fundamental ways in which mobile is revolutionizing public health. First, because of how mobile can empower us to lead healthier lifestyles in ways we've never had before, and this isn't just hype. There's been an explosion in mobile health apps, 97,000 across app stores worldwide. The second aspect of this revolution is how mobile health can support health systems. It will do this by making it easier for healthcare professionals to deliver services and treatments in ways that are effective, low-cost and convenient for the patient. And mobile health could allow us to scale up and sustain prevention efforts across entire countries. Now, at Public Health England, we're absolutely committed to grasping the digital opportunity and pushing ourselves to see how much further we can go with it. Now, we'll get further and we'll get faster if we learn together. So I'm excited that the Be Healthy and Be Mobile initiative has managed to bring together so many key partners. We are really proud to be a part of this collaboration. Thank you.
