Which disease is caused by alphavirus?

Alphaviruses, such as Chikungunya virus, O’Nyong–Nyong virus, Ross River virus, have been widely known to cause fever, rash, and rheumatic diseases.

What is meant by alphavirus?

Definition. Alphaviruses are infectious agents that replicate in humans and many animals; this viral genus includes Chikungunya virus, Semliki Forest virus and Sindbis virus. Alphaviruses are transmitted by arthropods, mainly mosquitoes, and thus are arboviruses.

How is alphavirus treated?

Treatment of illness: There is no specific treatment or established cure for alphaviruses. Supportive care (intravenous fluids, medicine to control fever and pain) is the standard treatment.

Is Chikungunya a flavivirus?

Introduction. Chikungunya virus (CHIKV) and Zika virus (ZIKV) are arthropod-borne viruses (arboviruses) transmitted by mosquitoes. Based on the most current taxonomy of viruses, CHIKV and ZIKV belong to the Togaviridae family and the Flaviviridae family, respectively.

How is alphavirus prevented?

Prevention. Alphavirus infection can be prevented by avoiding exposure to mosquitoes that transmit these viruses. Personal protective strategies include wearing repellent, staying in screened or air-conditioned dwellings, and avoiding outdoor activities during times when the vectors are most avidly seeking blood meals.

What diseases are caused by arbovirus?

These infections usually occur during warm weather months, when mosquitoes and ticks are active. Examples include California encephalitis, Chikungunya, dengue, Eastern equine encephalitis, Powassan, St. Louis encephalitis, West Nile, Yellow Fever, and Zika.

What causes Togavirus?

Togaviruses Causing Rash and Fever They include the alphaviruses, which are distributed worldwide and cause illness in many hundreds of thousands of people each year. Clinical illnesses caused by togaviruses range from mild fever to severe diseases, such as encephalitis and hemorrhagic fever.

Is Togavirus an arbovirus?

Togavirus, any of three genera of arthropod-borne viruses (arboviruses) of the family Togaviridae.

How many Alphaviruses are there?

There are 32 alphaviruses, which infect various vertebrates such as humans, rodents, fish, birds, and larger mammals such as horses, as well as invertebrates.

Is chikungunya epidemic or pandemic?

Are arboviruses genetically related?

Genetic diversity underlies individual differences in human disease pathogenesis and severity. Not surprisingly, the outcomes of arboviral infection are associated with many genetic mutations and single nucleotide polymorphisms (SNPs), the majority of which are related to immune pathways (Table 1).

What are the symptoms of Togavirus?

Is Covid an arbovirus?

In the early stage of the disease, arbovirus infection (dengue, chikungunya, Zika) and COVID-19 exhibit similar clinical and laboratorial manifestations, thereby rendering the diagnoses more difficult.

What diseases are caused by flavivirus?

Members of this family belong to a single genus, Flavivirus, and cause widespread morbidity and mortality throughout the world. Some of the mosquitoes-transmitted viruses include: Yellow Fever, Dengue Fever, Japanese encephalitis, West Nile viruses, and Zika virus.

Is veev an alphavirus?

Abstract: Venezuelan equine encephalitis virus (VEEV) is an alphavirus in the family Togaviridae. VEEV is highly infectious in aerosol form and a known bio-warfare agent that can cause severe encephalitis in humans.

Is rubella an alphavirus?

This family comprises two genera, the alphaviruses and rubiviruses. While the Alphavirus genus has approximately 40 recognized members, the Rubella virus is the only member of the Rubivirus genus.

Where does alpha virus come from?

Alphaviruses are transmitted by blood-sucking arthropods, typically the mosquito, and replicate in both arthropod and vertebrate hosts worldwide. Members of the genus are categorized into either the New World or Old World group based upon the area in which they are found and the disease they cause.

How can I recover from chikungunya fast?

Treat the symptoms:

  1. Get plenty of rest.
  2. Drink fluids to prevent dehydration.
  3. Take medicine such as acetaminophen (Tylenol®) or paracetamol to reduce fever and pain.
  4. Do not take aspirin and other non-steroidal anti-inflammatory drugs (NSAIDS until dengue can be ruled out to reduce the risk of bleeding).

Which medicine is best for chikungunya?

There are no specific drugs to treat chikungunya; doctors simply recommend rest and plenty of fluids. Over-the-counter medications will help ease fever and joint pain. Treatment
