What type of virus is Rift Valley Fever?
Rift Valley fever (RVF) is a disease of domestic ruminants, caused by an arbovirus belonging to the Phlebovirus genus (Bunyaviridae family). The RVF virus was first identified in 1931 during an investigation into an epidemic among sheep on a farm in the Rift Valley in Kenya.
Is Rift Valley Fever a flavivirus?

What is Gn and Gc?
Gn and Gc are two major antigenic components on the viral surface and are the targets of specific neutralizing antibodies (29). MAb 4–5 is a human-origin, neutralizing monoclonal antibody targeting Gn, showing cross-neutralizing activity to a wide range of SFTSV isolates in China (30).
Is Rift Valley Fever a bacteria?
Rift Valley fever (RVF) is a viral disease most commonly seen in domesticated animals in sub-Saharan Africa, such as cattle, buffalo, sheep, goats, and camels. People can get RVF through contact with blood, body fluids, or tissues of infected animals, or through bites from infected mosquitoes.
What is the vector of Rift Valley Fever?
Mosquitoes are both a reservoir and vector for RVFV, which means that they can maintain virus for life and transmit it to their offspring via eggs. After periods of heavy rainfall and flooding, an increased number of RVF virus-infected mosquitos may hatch and pass virus to people and animals.
What is the causative agent of Valley fever?
Valley fever, also called coccidioidomycosis, is an infection caused by the fungus Coccidioides. The fungus is known to live in the soil in the southwestern United States and parts of Mexico and Central and South America. The fungus was also recently found in south-central Washington.
Is hantavirus naked or enveloped?
Hantavirus virions are roughly spherical and highly heterogenic, varying from 120 to 160 nm in size. They expose glycoprotein spikes locally ordered into tetramers and also contain naked membrane patches on their surfaces (4, 5).
Why is it called the Rift Valley virus?
RVF virus is a member of the Phlebovirus genus. The virus was first identified in 1931 during an investigation into an epidemic among sheep on a farm in the Rift Valley of Kenya. Since then, outbreaks have been reported in sub-Saharan Africa.
What is the structure of hantavirus?
Hantavirus virions have spherical shape with size varying between 80 and 120 nm. Hantavirus genome is comprised of three segments of single stranded negative sense RNA. Based on their size, these three segments are named small (S), medium (M), and large (L).
What type of fungi is Cryptococcus?
Cryptococcus neoformans is a fungus that lives in the environment throughout the world. People can become infected with C. neoformans after breathing in the microscopic fungus, although most people who are exposed to the fungus never get sick from it.
What type of pathogen is Cryptosporidium?
Cryptosporidium is a microscopic parasite that causes the diarrheal disease cryptosporidiosis. Both the parasite and the disease are commonly known as “Crypto.”
Is cryptosporidiosis a virus or bacteria?
What is cryptosporidiosis? Cryptosporidiosis is a disease that causes watery diarrhea. It is caused by microscopic germs—parasites called Cryptosporidium.
Is hantavirus a RNA or DNA virus?
Like other members of the bunyavirus family, hantaviruses are enveloped viruses with a genome that consists of three single-stranded RNA segments designated S (small), M (medium), and L (large).
What pathogen causes hantavirus?
HPS in the US is mostly caused by Sin Nombre Hantavirus, a newly identified virus within the Bunyaviridae family. The virus is carried by the deer mouse (Peromyscus maniculatus). The deer mouse can be found in most parts of the United States, except the southeast.
