- II and IV
The correct answer is: C
Explanation
- Onchocerciasis, also known as river blindness, is a disease caused by infection with the parasitic worm Onchocerca volvulus.
Symptoms include severe itching, bumps under the skin, and blindness.
The disease is spread by repeated bites from infected black flies and these can be found virtually anywhere there is flowing water to serve as habitat for larvae.
- Schistosomiasis, also known as bilharzia, is a disease caused by parasitic worms.
Infection occurs when your skin comes in contact with contaminated freshwater in which certain types of snails that carry schistosomes are living.
- Salmonellosis is an infection with a bacteria called Salmonella, Salmonella live in the intestinal tracts of animals, including birds.
Commonly caused by contaminated food or water.
- Meningitis is an inflammation of the fluid and membranes (meninges) surrounding your brain and spinal cord. The swelling from meningitis typically triggers signs and symptoms such as headache, fever and a stiff neck.
Some fungal infections are transmitted by airborne dust particles. In addition, other types of meningitis can be transferred to humans by vectors such as mosquitoes
(for example, West Nile virus) or ticks (Lyme disease).
The bacteria that cause meningitis are transmitted from person-to-person through droplets of respiratory or throat secretions from carriers. Close and prolonged contact – such as kissing, sneezing or coughing on someone, or living in close quarters with an infected person, facilitates the spread of the disease.
