Mutations in mitochondrial DNA can cause many serious diseases and are inherited through the maternal line. Recently, doctors in the field of preventing the transmission of disease-causing mtDNA mutations have successfully researched and created a baby with three parents using the technique of replacing mitochondria in cells combined with artificial insemination.

Mitochondria are the energy factories for the body. When mitochondria are not active and do not perform normal functions, they will not provide enough energy for the body's activities, so mitochondrial diseases are syndromes that have a long "accumulation" time and are genetic. The incidence of mitochondrial diseases is about 1/5000 people. The problem of diagnosis and treatment for mitochondrial diseases is still being researched.

Fungal infections are one of the most common diseases in the world. Fungi exist everywhere: in the soil, water, air, on animals and plants, and even on the human body. When encountering favorable conditions such as hot and humid weather, reduced body resistance... fungi will grow and cause disease. Fungal diseases can occur in both adults and children.
