Washing hands with soap and water is the best way to get rid of germs in most situations. If soap and water are not readily available, you can use an alcohol-based hand sanitizer that contains at least 60% alcohol. You can tell if the sanitizer contains at least 60% alcohol by looking at the product label.
The MediaPipe Hand Landmarker task lets you detect the landmarks of the hands in an image.You can use this task to locate key points of hands and render visualeffects on them. This task operates on image data with a machine learning(ML) model as static data or a continuous stream and outputs hand landmarks inimage coordinates, hand landmarks in world coordinates and handedness(left/righthand) of multiple detected hands.

The hand landmarker model bundle contains a palm detection model anda hand landmarks detection model. The Palm detection model locates hands withinthe input image, and the hand landmarks detection model identifies specific handlandmarks on the cropped hand image defined by the palm detection model.
Since running the palm detection model is time consuming, when in video or livestream running mode, Hand Landmarker uses the bounding box defined by the handlandmarks model in one frame to localize the region of hands for subsequentframes. Hand Landmarker only re-triggers the palm detection model if the handlandmarks model no longer identifies the presence of hands or fails to track thehands within the frame. This reduces the number of times Hand Landmarker tiggersthe palm detection model.
A hand is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs. A few other vertebrates such as the koala (which has two opposable thumbs on each "hand" and fingerprints extremely similar to human fingerprints) are often described as having "hands" instead of paws on their front limbs. The raccoon is usually described as having "hands" though opposable thumbs are lacking.[1]
Among humans, the hands play an important function in body language and sign language. Likewise, the ten digits of two hands and the twelve phalanges of four fingers (touchable by the thumb) have given rise to number systems and calculation techniques.
Many mammals and other animals have grasping appendages similar in form to a hand such as paws, claws, and talons, but these are not scientifically considered to be grasping hands. The scientific use of the term hand in this sense to distinguish the terminations of the front paws from the hind ones is an example of anthropomorphism. The only true grasping hands appear in the mammalian order of primates. Hands must also have opposable thumbs, as described later in the text.
The hand is located at the distal end of each arm. Apes and monkeys are sometimes described as having four hands, because the toes are long and the hallux is opposable and looks more like a thumb, thus enabling the feet to be used as hands.
The thumb (connected to the first metacarpal bone and trapezium) is located on one of the sides, parallel to the arm. A reliable way of identifying human hands is from the presence of opposable thumbs. Opposable thumbs are identified by the ability to be brought opposite to the fingers, a muscle action known as opposition.
The carpal bones form two transversal rows, each forming an arch concave on the palmar side. Because the proximal arch simultaneously has to adapt to the articular surface of the radius and to the distal carpal row, it is by necessity flexible. In contrast, the capitate, the "keystone" of the distal arch, moves together with the metacarpal bones and the distal arch is therefore rigid. The stability of these arches is more dependent of the ligaments and capsules of the wrist than of the interlocking shapes of the carpal bones, and the wrist is therefore more stable in flexion than in extension.[12] The distal carpal arch affects the function of the CMC joints and the hands, but not the function of the wrist or the proximal carpal arch. The ligaments that maintain the distal carpal arches are the transverse carpal ligament and the intercarpal ligaments (also oriented transversally). These ligaments also form the carpal tunnel and contribute to the deep and superficial palmar arches. Several muscle tendons attaching to the TCL and the distal carpals also contribute to maintaining the carpal arch.[13]
The prehensile hands and feet of primates evolved from the mobile hands of semi-arboreal tree shrews that lived about 60 million years ago. This development has been accompanied by important changes in the brain and the relocation of the eyes to the front of the face, together allowing the muscle control and stereoscopic vision necessary for controlled grasping. This grasping, also known as power grip, is supplemented by the precision grip between the thumb and the distal finger pads made possible by the opposable thumbs. Hominidae (great apes including humans) acquired an erect bipedal posture about 3.6 million years ago, which freed the hands from the task of locomotion and paved the way for the precision and range of motion in human hands.[21] Functional analyses of the features unique to the hand of modern humans have shown that they are consistent with the stresses and requirements associated with the effective use of paleolithic stone tools.[22] It is possible that the refinement of the bipedal posture in the earliest hominids evolved to facilitate the use of the trunk as leverage in accelerating the hand.[23]
Effective from February 23, 2020, the Massachusetts Hands-Free law prohibits operators of motor vehicles from using any electronic device, including mobile telephones, unless the device is utilized in hands-free mode. The primary goal of this law is to reduce distracted driving and improve road safety for all.

We set out to determine the impact of washing hands with soap on the risk of diarrhoeal diseases in the community with a systematic review with random effects meta-analysis. Our data sources were studies linking handwashing with diarrhoeal diseases. Seven intervention studies, six case-control, two cross-sectional, and two cohort studies were located from electronic databases, hand searching, and the authors' collections. The pooled relative risk of diarrhoeal disease associated with not washing hands from the intervention trials was 1.88 (95% CI 1.31-2.68), implying that handwashing could reduce diarrhoea risk by 47%. When all studies, when only those of high quality, and when only those studies specifically mentioning soap were pooled, risk reduction ranged from 42-44%. The risks of severe intestinal infections and of shigellosis were associated with reductions of 48% and 59%, respectively. In the absence of adequate mortality studies, we extrapolate the potential number of diarrhoea deaths that could be averted by handwashing at about a million (1.1 million, lower estimate 0.5 million, upper estimate 1.4 million). Results may be affected by the poor quality of many of the studies and may be inflated by publication bias. On current evidence, washing hands with soap can reduce the risk of diarrhoeal diseases by 42-47% and interventions to promote handwashing might save a million lives. More and better-designed trials are needed to measure the impact of washing hands on diarrhoea and acute respiratory infections in developing countries.
An occupational or physical therapist can test the strength in your hands and help you regain or keep it. You also can do many exercises at home. For example, you might squeeze something like a tennis ball as hard as you can for 3 to 5 seconds, then rest briefly -- do that 10 times with each hand. Start with once a day or once every other day, depending on how your hands feel.
Over the years, the tops of your hands get lots of sun, which is a leading cause of this disease. A fair complexion, problems with your immune system, certain kinds of moles, and a family history of skin cancer can also raise your chances of having it.
Hand-foot-and-mouth disease is a mild, contagious viral infection common in young children. Symptoms include sores in the mouth and a rash on the hands and feet. Hand-foot-and-mouth disease is most commonly caused by a coxsackievirus.
Sores that develop in the back of the mouth and throat may suggest a related viral illness called herpangina. Other features of herpangina include a sudden high fever and, in some instances, seizure. In rare cases, sores develop on the hands, feet or other parts of the body.
Hand-foot-and-mouth disease is most common in children in child care. That's because young children need frequent diaper changes and help using the toilet. They also tend to put their hands in their mouths.
About half of all women and one-quarter of all men will experience the stiffness and pain of osteoarthritis (OA) of the hands by the time they are 85 years old. A degenerative disease that affects all the tissues of a joint, OA leads to the breakdown over time of the smooth, protective cartilage on the ends of bones, so bones rub together, causing pain. The 29 bones of your hands and wrists come together to form many small joints that can be affected by OA.
