Worms
Toxoplasmosis
TOXOPLASMOSIS A parasite most commonly transmitted from animals (pets) to humans by contact with contaminated faces.
Brucellosis and anthrax
The bacteria commonly transmitted by direct hand contact and producing a nosocomial infection is Staphylococcus aureus.
Lassa Fever
toxoplasmosis
The condition that is transmitted from one person to another either by direct or indirect contact with contaminated objects is known as a communicable or infectious disease. Examples include the common cold, influenza, and COVID-19.
HIV can be transmitted through:Sexual contact (both heterosexual and homosexual)Contaminated needles (ex. syringes, piercing instruments)Contaminated blood productsBreastmilkMother to child--in the womb
Influenza virus may be transmitted among humans in two ways: Ø by direct contact with infected individuals Ø by contact with contaminated objects (called fomites, such as toys, doorknobs)
An infectious disease is one that can be spread from person to person (or animal to animal). Where a medical condition is caused by a virus, bacteria, or parasite, their reproduction poses a threat to those in contact with the sufferer, or in the same surroundings. Sometimes there is an intermediate vector that spreads the disease, or it may be airborne, waterborne, or transmitted by direct contact. EXAMPLE: The virus for the common cold is spread by airborne fluid droplets or by contaminated surfaces. Measles and chickenpox are spread by contact.
It depends a great deal on the type of parasite. Some small ones can be easily transmitted by casual contact, lice is a good example. Others would be virtually impossible to transmit that way, such as a tapeworm.
Polio is transmitted, most commonly, through fecal matter and saliva.
