Summary
Hantaviruses are RNA viruses that infect rodents and can spread to humans, causing severe diseases like hantavirus pulmonary syndrome and hemorrhagic fever with renal syndrome. This review covers their virology, spread, and how they cause illness.
Area of Science:
- Virology
- Epidemiology
- Pathogenesis
Background:
- Hantaviruses are enveloped RNA viruses.
- Rodents are persistent hosts, excreting virus in saliva and urine.
- Human infection occurs through ecological overlap with infected rodents.
Purpose of the Study:
- To review the virology of hantaviruses.
- To examine the epidemiology of hantavirus infections.
- To understand the pathogenesis of hantavirus-related diseases.
Main Methods:
- Literature review of hantavirus research.
- Analysis of epidemiological data on hantavirus outbreaks.
- Synthesis of information on viral mechanisms and disease development.
Main Results:
- Hantaviruses cause two main clinical syndromes: hemorrhagic fever with renal syndrome (worldwide) and hantavirus pulmonary syndrome (Americas).
- Transmission is linked to rodent excreta and human encroachment into rodent habitats.
- Pathogenesis involves complex interactions between the virus and host immune system.
Conclusions:
- Hantaviruses represent significant emerging infectious agents.
- Understanding their transmission and pathogenesis is crucial for prevention and control.
- Further research is needed to combat these emerging viral threats.

Viral Mutations
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...
Transmission of Pathogens
Pathogens spread from their reservoirs to susceptible hosts through three main routes: contact transmission, vehicle transmission, and vector transmission. Each route involves distinct mechanisms of transfer.Contact TransmissionThis category includes direct contact, indirect contact, and droplet transmission:Direct contact involves immediate physical interaction between individuals—such as a handshake—which can spread pathogens like Streptococcus pyogenes, the bacterium responsible for...
Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
Coronavirus
Coronaviruses, including the severe acute respiratory syndrome coronavirus (SARS-CoV), are enveloped viruses characterized by their single-stranded, positive-sense RNA genome and helical nucleocapsid structure. The hallmark of these viruses is their club-shaped spike (S) glycoproteins that protrude from the viral envelope, facilitating attachment to host cells. Typically, coronaviruses infect the upper respiratory tract, often causing mild or asymptomatic disease. However, certain strains like...
