What type of microbe causes chickenpox?
Chickenpox is a highly contagious disease caused by the varicella-zoster virus (VZV). It can cause an itchy, blister-like rash.
Can microbes cause chickenpox?
Microorganism: the virus responsible for chicken pox and shingles (VZV or varicella-zoster virus) is a member of the Herpesviridae family.
What type of microbe is varicella-zoster virus?
Varicella zoster virus (VZV) is an exclusively human neurotropic alpha-herpesvirus. Primary infection causes varicella (chickenpox), after which virus becomes latent in cranial nerve ganglia, dorsal root ganglia, and autonomic ganglia along the entire neuraxis.
Is chicken pox bacterial fungal or viral?
Chickenpox is a viral infection caused by the varicella-zoster virus (VZV), which is in the herpesvirus family. These viruses infect many tissues during primary infection and then become dormant; they can reactivate later to cause disease.
Is chickenpox a retrovirus?
Human alphaherpesvirus 3 (HHV-3), usually referred to as the varicella-zoster virus (VZV), is one of nine herpesviruses known to infect humans….Varicella zoster virus.
| Human alphaherpesvirus 3 | |

What is the method of transmission for chickenpox?
Transmission. Varicella is highly contagious. The virus can be spread from person to person by direct contact, inhalation of aerosols from vesicular fluid of skin lesions of acute varicella or zoster, and possibly through infected respiratory secretions that also may be aerosolized.
What is the epidemiology of chickenpox?
According to national seroprevalence data from the pre-vaccine era, greater than 95 percent of persons in the United States acquired varicella before 20 years of age, and fewer than 2 percent of adults were susceptible to infection [3-6].
How does VZV cause chickenpox?
Varicella (chickenpox) is an acute infectious disease. It is caused by varicella-zoster virus (VZV), which is a DNA virus that is a member of the herpesvirus group. After the primary infection, VZV stays in the body (in the sensory nerve ganglia) as a latent infection. Primary infection with VZV causes varicella.
Is varicella zoster DNA or RNA?
Varicella-Zoster Virus (VZV) VZV is a DNA virus and is a member of the herpesvirus group. Like other herpesviruses, VZV persists in the body as a latent infection after the primary (first) infection; VZV persists in sensory nerve ganglia. Primary infection with VZV results in varicella.
Which microorganism causes measles?
Measles is an acute infection caused by the rubeola virus. It is highly contagious and usually seen in children. The measles virus (MV) belongs to the genus Morbillivirus of the family Paramyxoviridae.
Does chicken pox use DNA or RNA?
VZV is a DNA virus and is a member of the herpesvirus group. Like other herpesviruses, VZV persists in the body as a latent infection after the primary (first) infection; VZV persists in sensory nerve ganglia. Primary infection with VZV results in varicella.
Is chicken pox virus DNA or RNA?
Varicella-zoster virus (VZV) is an enveloped double-stranded DNA virus belonging to the family Herpesviridae [70]. VZV is also called human herpesvirus type 3.
