Humans use waves in various ways, such as for communication through radio waves, navigation through GPS signals, heating food through microwaves, and seeing objects through light waves (such as in optical technology). Waves are also used in medical imaging techniques like ultrasound and X-rays for diagnosing diseases.
The Doppler shift affects waves reflected or emitted by a moving body as a stationary object's waves are equidistantly placed from each other but when an object moves one way the wavelength of the emitted waves is higher on the side of the destination but on the opposite side the wavelengths are lower this is how the Doppler shift affects emitted or reflected waves. The wavelength is given as lambda or λ and velocity is given by v.
this is because diseases are non communicable not like micro organisms that can also spread from body to body.
Surface waves travel slower than body waves.

Ionizing radiation, such as X-rays and gamma rays, are the most dangerous electromagnetic waves to humans. These high-energy waves have enough energy to ionize atoms and molecules in our body, leading to cellular damage and an increased risk of cancer. It's important to minimize exposure to ionizing radiation for safety.

P-waves.
Micro Means extremely small, we can only see micro-organisms in a microscope, Every Living creature has micro organisms on and in there body! even humans possess micro-organisms, such as bacteria, fungi and a virus, we all have these.
