(c)T.B
(d)Kala-azar

Answer 1

AZT (azidothymidine) is an antiviral drug that is used against Human immunodeficiency virus infection. A person who is infected by this virus loses the ability of adaptive immunity which makes them vulnerable to other secondary infections.

Complete answer:
AZT is also known as azidothymidine or zidovudine is an antiretroviral drug used to stop and treat AIDS. AIDS stands for Acquired Immunodeficiency syndrome and this drug is used to slow down the development of AIDS in patients infected with HIV. AZT comes under the group of drugs called the nucleoside reverse transcriptase inhibitors (NRTIs) which are effective against HIV when the virus is propagating into proviral DNA. Reverse transcriptase is an enzyme needed by retroviruses (especially HIV) to convert viral single-stranded RNA into proviral double-stranded DNA and zidovudine 5-triphosphate the active compound of AZT shows a high affinity for these enzymes. Due to this reason AZT is used as a medication for AIDS.

Additional Information: -As of now, there is no effective cure for HIV, which means the person who is infected with HIV has to carry it for their whole life, but with proper care HIV can be controlled, and the spreading of HIV to another person can be stopped.
-HIV came to humans from a type of chimpanzee in Central Africa. Simian immunodeficiency virus or SIV is a similar virus found in chimpanzees which got transferred to humans and got adapted to humans.
-Many studies tell that HIV must have transferred from chimpanzees to humans in the late 1800s.
So, the correct answer is AIDS.

Note: -Fever, skin rashes, sleeplessness, muscle pains, sore throat, tiredness, swollen lymph nodes, and ulcers in the mouth are the common symptoms of HIV.
-In the first stage of acute HIV infection, the patient will be highly contagious, as there is a large number of HIV present in their blood.
-The second stage of HIV is called asymptomatic HIV infection or clinical latency, where the patient doesn't show any symptoms.
