Governments and health systems are starting to use mobile phones to communicate with clients, patients
, and the public. Common types of communication are text messages that remind people to go to appointments or to take their medicines. Other types of communication include phone calls or video messages that offer healthcare information, advice, monitoring, and support. This type of communication may be particularly relevant in situations and settings where it is difficult to meet patients and the public face-to-face, such as during pandemics.
