"Very Sick Patients Must Take Double Exercise"

Varicella (chickenpox)- 1st day
Scarlet fever - 2nd day
Pox (smallpox) - 3rd day
Mumps - 4th day
Typhus - 5th day
Dengue - 6th day
Enteric fever (typhoid) - 7th day


In Short
Varicella Rashes:
The most distinctive sign of chickenpox infection is an itchy rash of red spots and blisters. It takes about 1 or 2 days for a chickenpox red spot (macule) to go through all of its stages, including blistering, bursting, drying, and crusting over



Scarlet Fever  Scarlet fever is a disease caused by an infection with group A beta-hemolytic streptococcal bacteria. The rash initially appears on the neck and chest, then spreads over the body. While the rash is still red, the patient may develop Pastia's lines, bright red coloration of the creases under the arm and in the groin.
 A few days following generalization of the rash, it becomes more intense along skin folds and produces lines of confluent petechiae known as the Pastia sign. These lines are caused by increased capillary fragility.The rash begins to fade 3-4 days after onset, and the desquamation phase begins. This phase begins with flakes peeling from the face. Peeling from the palms and around the fingers occurs about a week later and lasts for about a month after onset of the disease.

Small Pox

A rash emerges first as small red spots on the tongue and in the mouth.

These spots develop into sores that break open and spread large amounts of the virus into the mouth and throat. At this time, the person becomesmost contagious.

Around the time the sores in the mouth break down, a rash appears on the skin, starting on the face and spreading to the arms and legs and then to the hands and feet. Usually the rash spreads to all parts of the body within 24 hours. As the rash appears, the fever usually falls and the person may start to feel better.

By the third day of the rash, the rash becomes raised bumps.

By the fourth day, the bumps fill with a thick, opaque fluid and often have a depression in the center that looks like a bellybutton. (This is a major distinguishing characteristic of smallpox.)

Fever often will rise again at this time and remain high until scabs form over the bumps.
The bumps become pustules—sharply raised, usually round and firm to the touch as if there’s a small round object under the skin. People often say the bumps feel like BB pellets embedded in the skin.
The pustules begin to form a crust and then scab.

By the end of the second week after the rash appears, most of the sores have scabbed over.
The scabs begin to fall off, leaving marks on the skin that eventually become pitted scars. Most scabs will have fallen off three weeks after the rash appears. The person is contagious to others until all of the scabs have fallen off
