With reference to the Lassa fever, consider the following statements:...
Lassa fever is one of the hemorrhagic fever viruses that can cause severe illness in humans. It is endemic to West Africa, particularly in countries such as Nigeria, Sierra Leone, Guinea, and Liberia. Let's look at the given statements and check their correctness:
1. Lassa fever is one of the hemorrhagic fever viruses.
This statement is correct. Lassa fever is caused by Lassa virus, which belongs to the Arenaviridae family of viruses, just like Ebola and Marburg viruses.
2. Like the Ebola virus, Lassa fever is contagious from person to person.
This statement is incorrect. While Lassa fever is a serious and potentially fatal disease, it is not as contagious as Ebola virus. Lassa virus is primarily transmitted from rodents, especially Mastomys rats, to humans through contact with their urine or feces. Person-to-person transmission of Lassa fever occurs through direct contact with the blood, urine, feces, or other bodily fluids of an infected person.
3. Lassa virus is typically transmitted by the urine or feces of Mastomys rats to humans.
This statement is correct. Mastomys rats are the natural reservoir host of Lassa virus, and they shed the virus in their urine and feces. Humans can become infected by coming into contact with objects or food contaminated with rodent urine or feces, or by inhaling tiny particles of these materials from the air.
Therefore, the correct answer is option C, which includes statements 1 and 3 only.

With reference to the Lassa fever, consider the following statements:...
Lassa fever:
- Lassa fever is one of the hemorrhagic fever viruses like Ebola virus, Marburg virus, and others. Hence, statement 1 is correct.
- It is caused by the Lassa virus, a member of the arenavirus family of viruses.
- Unlike the Ebola virus, Lassa fever is not as contagious from person to person, nor as deadly. Hence, statement 2 is not correct.
- Lassa virus is typically transmitted by the urine or feces of Mastomys rats to humans. Hence, statement 3 is correct.
- Health workers may be infected by direct contact with blood, body fluids, urine, or stool of a patient with Lassa fever.
- Lassa fever occurs primarily in West Africa in areas where these rodents live. Blueprint Priority Diseases of WHO: Worldwide, the number of potential pathogens is very large, while the resources for disease research and development (R&D) is limited. To ensure efforts under WHO‘s R&D Blueprint are focused and productive, a list of diseases and pathogens are prioritized for R&D in public health emergency contexts. A WHO tool distinguishes which diseases pose the greatest public health risk due to their epidemic potential and/or whether there is no or insufficient counter-measures.At present, the priority diseases are:
- COVID-19
- Crimean-Congo hemorrhagic fever
- Ebola virus disease and Marburg virus disease
- Lassa fever
- Middle East respiratory syndrome coronavirus (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS)
- Nipah and henipaviral diseases
- Rift Valley fever
- Zika
- Disease X‖: Disease X represents the knowledge that a serious international epidemic could be caused by a pathogen currently unknown to cause human disease. The R&D Blueprint explicitly seeks to enable early cross-cutting R&D preparedness that is also relevant for an unknown ―Disease X‖.
