The common cold is a group of symptoms in the upper respiratory tract caused by a large number of different viruses. Although more than 200 viruses can cause the common cold, the perpetrator is usually the rhinovirus, which is to blame for causing 10% to 40% of colds. Also, the coronaviruses cause about 20% of colds, and the respiratory syncytial virus (RSV) and parainfluenza virus each cause 10% of colds.
Malaria is a mosquito-borne infectious disease of humans and other animals caused by parasitic protozoans (a group of single-celled microorganism) belonging to the genus Plasmodium. Malaria causes symptoms that typically include fever, fatigue, vomiting and headaches. In severe cases, it can cause yellow skin, seizures, coma or death.
Anthrax is a rare but serious illness caused by a spore-forming bacterium, Bacillus anthracis. Anthrax mainly affects livestock and wild game. Humans can become infected through direct or indirect contact with sick animals.
There's no evidence that anthrax is transmitted from person to person, but it's possible that anthrax skin lesions may be contagious through direct contact. Usually, anthrax bacteria enter the body through a wound in the skin. You can also become infected by eating contaminated meat or inhaling the spores.
Athlete's foot is a common skin infection of the webs of the toes and soles of the feet. When caused by a fungus, athlete's foot may spread to the palms, groin, and body. Fungal infections of the feet are contagious and can be spread person to person or by walking on contaminated objects and floors.
