At present, the situation of infectious disease prevention and control is still severe, the threat of traditional infectious diseases still exists, and new infectious diseases continue to appear. Major infectious diseases such as AIDS and tuberculosis have become serious public health and social problems that threaten human health and survival. What's more serious is that Gongcai.com learned that some studies have shown that the number of AIDS cases among young students has been on the rise in recent years, and that tuberculosis, which is spread through the air and droplets, often occurs in schools.
Due to various reasons, especially for the purpose of protecting patient privacy, or interference from stakeholders, some isolation measures have not been implemented well, leading to the outbreak of a cluster of epidemics, which seriously endangers public health safety. How to properly handle the relationship between privacy protection of patients with infectious diseases and public health security is an important topic that needs to be studied in the field of public health.

Since there are no cameras and few tools available to healthcare providers or relatives, it is impossible to remotely monitor patient safety in hospitals and assisted life care facilities. According to Gongcai.com, someone has developed a new type of infrared sensor system that can provide real-time data of patients' activities in the room and protect their privacy.
The system was developed by Rensselaer Polytechnic Institute Lighting System and Application Center (LESA). The original design goal was to make the building's energy management more effective. However, researchers realized that it also provides an effective solution to health care.
Bob Kalicek, director of the LESA Center, said: "We can find a balance between information and privacy." It turns out that lighting and light field sensing technology provide us with a very powerful tool to determine where the patient is and estimate What they are doing, but it does not show the patient's appearance. "
This system relies on what Karlicek calls patient-centric control, using infrared sensors to measure the distance between objects in the room. It does not contain any image information, it just measures the distance and judges whether a person is standing, sitting or lying on the floor. It can actually distinguish where people stand and how they interact with others. Such measurement can remind nurses that someone has fallen, record the time of the last patient examination, and even help detect whether cognitive abilities are normal.
The novelty of this method is the development of a very powerful infrared sensor with built-in data analysis capabilities, which allows the sensors to collect data, process the data, and communicate with each other in order to track movement in the room. Affordability is very important for widespread implementation.
