Question

Which of the following diseases spread through infected needles or blood transfusion?
A) Jaundice
B) AIDS
C) Measles
D) Polio

Answer 1

Hint: Viral diseases occur when an infection enters the body and attacks the body’s cells. On the off chance that the body’s resistant framework can’t ward off the infection, it duplicates and spreads to different cells, rehashing the cycle and prompting far and wide contamination.

Complete step by step answer: AIDS stands for acquired immunodeficiency syndrome. It is an infection which is caused by the Human immunodeficiency virus (HIV). The causative agent of the disease is a virus, therefore, the disease can spread from one person to another by sexual content. The disease also spreads through the use of infected needles, syringes and a blood transfusion from the infected person.
i. Jaundice: Jaundice may occur if the liver can’t efficiently process red coloured blood cells as they break down. It’s normal in healthy new-borns and usually clears on its own. It causes yellow skin by the build-up of bilirubin in the blood.
ii. Measles: Measles is a viral infection that is usually observed in small children, but it can be easily preventable by a vaccine. This disease spreads through the air by respiratory droplets produced by coughing or sneezing.
iii. Polio: it is a rare disease which is caused by a virus. But it is easily preventable. Polio is transmitted through contaminated water or food or through contact with an infected person.
Hence, the correct answer is option B.

Note: AIDS begins with HIV infections. People infected with HIV may have no symptoms for ten years or longer. But, they can still transmit the infection to others. Meanwhile, their immune system gradually weakens until they develop AIDS.
