Fifth disease, also known as erythema infectiosum and slapped cheek syndrome, [3] is a common and contagious disease caused by infection with parvovirus B19. [4] This virus was discovered in 1975 and can cause other diseases besides fifth disease. [ 5 ]
It is the classic cause of the childhood rash called fifth disease or erythema infectiosum, or "slapped face syndrome". [5] [6] The name comes from it being the fifth in a list of historical classifications of common skin rash illnesses in children. [7] The virus was discovered by chance in 1975 by Australian virologist Yvonne Cossart.
The terms "intrinsic incubation period" and "extrinsic incubation period" are used in vector-borne diseases. The intrinsic incubation period is the time taken by an organism to complete its development in the definitive host. The extrinsic incubation period is the time taken by an organism to develop in the intermediate host. [citation needed]

Fifth Disease, or parvovirus B19, also known as erythema infectiosum. Roseola, a viral infection occasionally still called Sixth disease, which can cause high fever and rash.
In epidemiology, particularly in the discussion of infectious disease dynamics (mathematical modeling of disease spread), the infectious period is the time interval during which a host (individual or patient) is infectious, i.e. capable of directly or indirectly transmitting pathogenic infectious agents or pathogens to another susceptible host ...
The outbreak now seems to have slowed, with Nov 29 marking 28 days without a new case and 22 days since the last patient was discharged from hospital, although there is long incubation period ...
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
