SCARLATINAL RUBELLA (rubeola scarlatinosa; synonym: the fourth disease, Filatov's disease — Dyyuksa) — the acute infectious disease which is characterized by emergence on skin of punctate scarlatiniform rash.

N. F. Filatov (1885) considered S. to. as an independent disease, however, considering small number of the observations, did not consider a question finally solved. Most of researchers holds the opinion that the arguments given to advantage of existence of this nosological form are not convincing also that under S. to. usually mean easy forms scarlet fevers (see).

The etiology of a disease and the main patterns of its epidemiology are unknown. The incubation interval proceeds 1 — 3 week of S. to. it is characterized by insignificant fever without disturbance of health of the patient. The main symptom — punctate scarlatiniform rash, edges remains 2 — 3 days and does not leave behind either pigmentation, or a peeling. Skin dot hemorrhages are not observed. The easy hyperemia of a pharynx, swelling of palatine tonsils are noted. The changes of language typical for scarlet fever, and also submaxillary lymphadenitis do not happen.

Considering that under S.'s diagnosis to. the easy form of scarlet fever can disappear, the same treatment and the same anti-epidemic actions is recommended, as well as at scarlet fever (see).
