HIV is (c) a viral disease. HIV, or Human Immunodeficiency Virus, is a lentivirus that attacks the immune system. It specifically targets CD4 cells, a type of T cell crucial for the body’s immune response. HIV weakens the immune system over time, making the body vulnerable to opportunistic infections and cancers. If left untreated, HIV can progress to AIDS (Acquired Immunodeficiency Syndrome), the advanced stage of the disease characterized by severe immune deficiency and opportunistic infections. HIV is primarily transmitted through unprotected sexual contact, sharing of contaminated needles, or from mother to child during childbirth or breastfeeding.
Kala-azar, also known as visceral leishmaniasis, is transmitted by (c) Anopheles fly. This disease is caused by the protozoan parasite Leishmania donovani, primarily transmitted to humans through the bite of infected female sandflies of the genus Phlebotomus (Old World) or Lutzomyia (New World).

Kala-azar, also known as visceral leishmaniasis, is transmitted by (c) Anopheles fly. This disease is caused by the protozoan parasite Leishmania donovani, primarily transmitted to humans through the bite of infected female sandflies of the genus Phlebotomus (Old World) or Lutzomyia (New World). These sandflies typically thrive in rural areas with poor sanitation and are most active during dusk and dawn. When an infected sandfly bites a human, it injects the parasite into the bloodstream, leading to the development of kala-azar. Effective control measures, such as vector control and treatment of infected individuals, are essential to prevent the spread of this disease.
The virus that causes AIDS was identified in the year (c) 1983. This breakthrough discovery occurred when scientists Françoise Barré-Sinoussi and Luc Montagnier, working at the Pasteur Institute in France, isolated and characterized the Human Immunodeficiency Virus (HIV).

The virus that causes AIDS was identified in the year (c) 1983. This breakthrough discovery occurred when scientists Françoise Barré-Sinoussi and Luc Montagnier, working at the Pasteur Institute in France, isolated and characterized the Human Immunodeficiency Virus (HIV). Their pioneering research provided crucial insights into the nature of the virus responsible for AIDS (Acquired Immunodeficiency Syndrome), revolutionizing our understanding of the disease. This identification laid the foundation for subsequent research efforts aimed at developing effective treatments and prevention strategies to combat the global HIV/AIDS epidemic, which has had a profound impact on public health worldwide.
Malaria parasites that cause deadly malaria are (b) Plasmodium falciparum. This species is responsible for the majority of severe malaria cases and deaths globally, making it the deadliest of the malaria parasites. Plasmodium falciparum can lead to severe complications such as cerebral malaria, orgaRead more
Malaria parasites that cause deadly malaria are (b) Plasmodium falciparum. This species is responsible for the majority of severe malaria cases and deaths globally, making it the deadliest of the malaria parasites. Plasmodium falciparum can lead to severe complications such as cerebral malaria, organ failure, and death, particularly in young children and pregnant women. While other species like Plasmodium vivax (c) and Plasmodium malariae (a) can cause malaria, they typically result in milder forms of the disease. Plasmodium ovale (d) is another species but is less common and usually causes less severe symptoms compared to P. falciparum.
The disease transmitted only by inheritance among the options is (c) Haemophilia. It is a genetic disorder characterized by a deficiency in clotting factors, primarily factor VIII (hemophilia A) or factor IX (hemophilia B). Haemophilia is inherited through a recessive X-linked pattern, meaning it prRead more
The disease transmitted only by inheritance among the options is (c) Haemophilia. It is a genetic disorder characterized by a deficiency in clotting factors, primarily factor VIII (hemophilia A) or factor IX (hemophilia B). Haemophilia is inherited through a recessive X-linked pattern, meaning it primarily affects males who inherit the defective gene on their X chromosome from their carrier mother. While myocardial infarction (a), diabetes mellitus (b), and cancer (d) can have genetic components, they can also result from various environmental and lifestyle factors, not solely inheritance.
