Three Day Fever (roseola infantum)
Posted by Avatar
Also called “Sixth Disease”, it is common in children characterized by high fever and a pink rash that lasts for about three days hence the name. The disease is caused by a strain of the human herpes virus and being viral, it cannot be influenced or treated with antibiotics. The high fever associated with the disease should be managed and carefully monitored for as with any disease accompanied by high fever, proper cooling and hydration should be observed. Common medication such as paracetamol and other variants can be given to lower the fever accompanied by lots of fluids such as fruit juice and other non-carbonated liquids (water has little electrolyte content and can even induce dehydration). If possible obtain electrolyte liquids such as Pedialyte or other oral rehydration fluids to prevent excessive dehydration. The incubation period is between 10 to 15 days and is contagious during the whole period (three days at the most) so avoid exposing children under three years of age to prevent a similar infection to that child.

Though people frequently think of mathematics as a summit of intellectual achievement of humankind, research reveals that some instinct about numbers, counting and mathematical ability is basic to almost all animals. For example, creatures that gather or hunt for food keep track of the approximate number of food items they procure in order to return to the places where they get the most sustenance. Humans share this very basic “number sense,” allowing them, at a glance, to estimate the number of people in a subway car or bus, Halberda says.
The students were flashed a group of yellow and blue dots, and had to estimate which colour group was bigger.
The Johns Hopkins team wondered whether this basic, seemingly innate number sense had any bearing on the formal mathematics that people study in school. So the researchers asked 64 14-year-olds to look at flashing groups of yellow and blue dots on a computer screen and estimate which dots were more numerous. Though most of the children easily arrived at the correct answer when there were (for example) only 10 blue dots and 25 yellow ones, some had difficulty when the number of dots in each set was closer together. Those results helped the researchers ascertain the accuracy of each child’s individual number sense. (You can test your own number sense on the New York Times website.)
Fifth Disease (erythema infectiosum)

The childhood disease is a mild one and is caused by a virus so no antibiotic would be effective against it. It has no lasting effects and is characterized by red specks on the nose, cheeks, arms buttocks and thighs that are often blurred making it look as if the child has been slapped. Also called the “slapped cheek” syndrome, it can last for 14 days but is rarely accompanied by fever in children between age 4 and 12. The disease is an untreatable one and it usually goes away by itself. The infection manifests itself about two weeks after exposure and when the rashes appear, it is usually not infectious anymore. Pregnant women should avoid exposure to the disease for it is infectious and can lead to miscarriages. If you suspect contact with a child that is infected by the disease, contact a doctor immediately for close monitoring of you and the unborn fetuses health.
