Summary
Young birds are crucial for Eastern equine encephalitis virus (EEEV) outbreaks. Mosquitoes feeding on young-of-the-year birds, not adults, are key to initiating and sustaining EEEV transmission cycles.
Area of Science:
- Veterinary Medicine
- Epidemiology
- Ecology
Background:
- Eastern equine encephalitis virus (EEEV) is an endemic arbovirus in the United States.
- Arboviral transmission dynamics are influenced by interactions between mosquito vectors and avian hosts.
Purpose of the Study:
- To investigate the role of young-of-the-year (YOY) birds in EEEV transmission dynamics.
- To model the impact of vector-host interactions on EEEV enzootic outbreaks.
Main Methods:
- Development of a mathematical model to simulate EEEV transmission.
- Sensitivity analyses to identify key parameters influencing EEEV infection levels.
Main Results:
- Eleven parameters significantly affected predicted EEEV infection levels.
- Four key parameters related to vector interactions with YOY birds.
- Adult birds could not substitute for YOY birds in initiating or maintaining EEEV outbreaks.
Conclusions:
- Young-of-the-year birds play a critical role in establishing and maintaining enzootic EEEV outbreaks.
- Targeting vector-host interactions with YOY birds may be crucial for EEEV control strategies.

01:25Arboviral 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...
01:28Rabies
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...
01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:10Retrovirus Life Cycles
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
