Morbilliform rash, or \\"measles-like\\" maculopapular skin eruption, is commonly caused by certain drug reactions or viral diseases. Maculopapular rashes are skin eruptions that exhibit both the characteristics of a macule and papule. Macules are small, circumscribed and discolored spots on the skin. The diameter of a macule is not more than .4 inches (10 mm). Papules, on the other hand, are eruptions on the skin, which can look something like a pimple. Morbilliform rashes, therefore, are raised, discolored spots that spread symmetrically across the body.
These rashes may occur due to bacterial infections, drug reactions, and specific or non-specific viral exanthems, also known as viral rashes. A viral exanthem is non-specific if there is no exact information on the virus that has caused the rash. In such a case, the clinician identifies the presence of the virus that is likely to have caused the rash. Morbilliform rash is a \\"late drug rash.\\" It appears on the skin of the affected individual after one to two weeks of exposure to drugs, such as antibiotics or barbiturates. Drug-caused rashes of this kind are usually associated with penicillin, cephalosporins, sulphonamides, and anticonvulsants. Morbilliform rashes often occur in children affected by viral diseases such as measles, Rubella, Roseola, and Erythema infectiosum. In adults, these rashes are usually non-specific viral rashes. This type of rash is also frequently seen in patients who administer ampicillin for the treatment of mononucleosis caused by Epstein-Barr virus or cytomegalovirus. People with human immunodeficiency virus (HIV) tend to develop an acute morbilliform rash when treated with sulfa drugs.
This rash can also appear as a consequence of certain viral diseases. If antibiotics have been started for the patient during the early stages of the viral disease, then the appearance of a morbilliform rash may lead to confusion in diagnosis. Once a drug-induced morbilliform rash is diagnosed, the doctor may ask the patient to discontinue the use of a particular drug.
Usually, oral antihistamines or topical corticosteroids are prescribed for treating these types of rashes. Oral corticosteroids are avoided, as there are chances of the rash to worsen during the steroid therapy, which may lead to the wrong diagnosis. A drug-induced morbilliform rash will usually subside within almost two weeks after the discontinuation of the particular drug. When this type of rash heals, the affected skin sheds or peels, which is also known as skin desquamation.

As their name suggests, these termites nest beneath the ground in the soil. They are also the most common species of termites infesting homes in the U.S. Unfortunately, eastern subterranean termites dont care where the wood they devour comes from, and their search often brings them into our homes and businesses. They invade this wood by constructing mud tubes (or passageways) from their nests in the soil into homes where they feed on the wood structure, which over time, can cause a lot of damage. Seeing these mud tubes is a sign that you have termite activity in your home.
These termites live inside wood and get the moisture they need to survive either from the wood itself or from humidity in the air. This is why drywood termites are often found in humid, coastal areas.
Colonies of drywood termites are much smaller than those of subterranean termites, and a mature colony may have only a few hundred or few thousand members. The winged males and females mate and create new colonies in a crack or other opening in wood.
Some signs of termite activity were mentioned above. These signs can vary based on the species of termite you're dealing with. When you notice these signs, you should call on a termite control professional to help you deal with this potentially serious situation rather than trying any DIY treatments.
