Six types of Exanthem have been discovered in total. Of these, four are viral in nature.

Viral Exanthem

Exanthem caused by viral microbes has been differentiated into four types. These are:

Measles

Also known as “Rubeola” or “First Disease”, this condition originates due to an infection caused by a type of Paramyxoviridae virus that is also referred to as “Measles Virus”. Patients usually suffer from fever, cough, muscular pain and rashes.

Rubella

It was identified in 1881 and is also known as “Third Disease”. It results from a type of Rubvirus, popularly called “Rubella Virus”. Individuals suffering from Rubella typically experience discomforts headaches, runny nose, fever and a general feeling of malaise.

Erythema Infectiosum

Also referred to as “Fifth Disease”, it was detected as a distinct disorder in 1896. The condition results from an infection by Parovirus B19. People with this disorder typically suffer from fever, rashes, joint pain and temporary anemia.

Roseola Infantum

It is also known as “Sixth Disease” or “Exanthem Subitum” and is caused by not one but two types of virus, HHV-6 and HHV-7. The symptoms of this condition typically involve runny nose, irritability, sore throat, redness of the eyes and high fever.

Non-viral Exanthem

The two types of Exanthem, caused by non-viral conditions, include

Scarlet Fever

Also known as “Second Disease”, it is caused due to bacterial infection. The bacterium Streptococcus pyogenes is responsible for this disease. The condition affected many people in the 17th century.

Fourth Disease

It was first described in 1900 and is said to result due to infection by the bacterium Staphylococcus aureus. It is regarded to be a rare condition these days.

Unilateral Laterothoracic Exanthema

The condition was first described in the US in 1962. It occurs most commonly in children, but can also affect adults. A viral prodrome may or may not precede the disease. It is characterized by blending of Erythematous papules mostly on one side of the body. Generally, it persists for 4-6 weeks though it may also last for as little as 2 weeks. The disease has been inconsistently related to viral infection, particularly Parvovirus B-19.

Polymorphous Exanthem

It is a form of skin eruption arising on the trunk and limbs. It may have various forms, involving a diffuse Scarlatiniform rash, Morbilliform Maculopapular eruption and Urticarial Exanthem. Vesicles and Bullae are not found. Generally, the rash arises within five days after an onset of fever.

Boston Exanthem

It is a cutaneous disorder that arises as an epidemic in Boston. It develops due to Echovirus 16.

Infectious Exanthem

It is a generalized cutaneous eruption and is related with a primary systemic infection. The condition is frequently accompanied by oral mucosal lesions, that is, an enanthem. It is mostly of caused by virus but can also result from parasites, bacteria and Rickettsia.

The main symptoms of this condition are:

  • Fever
  • Irritability

For most sufferers of non-specific exanthems, treatment is usually unnecessary as the condition is usually temporary and resolves spontaneously. If required, symptomatic treatment can be carried out with Paracetamol and/or topical or oral antihistamines.
