Category: Infectious Diseases Chickenpox's initial symptoms include a prodrome of fever and malaise (common in adults) 1-2 days before the onset of a characteristic rash. The rash is pruritic and first appears on the head, chest and back before spreading to the extremities.
Category: Infectious Diseases Chickenpox is a highly contagious, vaccine-preventable, viral illness characterized by a rash that spreads in a cephalocaudal (head to toe) progression and rapidly progresses from macules and papules to vesicles and then scabs.
Category: Infectious Diseases Exanthem subitum is an acute viral illness characterized by 3-5 days of high fever followed by defervescence and the appearance of a blanching macular or maculopapular centrifugal rash.
Category: Infectious Diseases Human herpes virus 6 is the most frequent cause of exanthem subitum (also termed sixth disease, roseola), but it can also be caused by human herpes virus 7, enteroviruses or adenoviruses.
Category: Infectious Diseases Erythema infectiosum is a self-limiting febrile viral illness that produces a characteristic “slapped cheek” facial rash followed by a lace-like reticular rash of the trunk and extremities. Patients are most infectious prior to rash development.
Category: Infectious Diseases Rubella and measles are similar but have some distinct differences. Rubella is characterized by low-grade fever, lymphadenopathy and rash. Measles is characterized by high-grade fever, cough, coryza, conjunctivitis and rash.
Category: Infectious Diseases With rubella, up to 70% of adolescents and adult females develop arthralgia and arthritis that may persist for several months. Complications are more common in older patients and may include thrombocytopenic purpura and encephalitis.
Category: Infectious Diseases Following a 12- to 23-day incubation period, patients with rubella develop a low-grade fever, lymphadenopathy and a mild maculopapular rash that proceeds in a cephalocaudal (head to toe) and outward progression.
Category: Infectious Diseases Rubella (also called the german measles, 3-day measles) is a contagious, vaccine-preventable, viral illness characterized by low-grade fever, lymphadenopathy and a mild 3-day maculopapular rash.
Category: Infectious Diseases Patients with mumps are considered contagious and should be isolated, with droplet precautions for at least 5 days after the onset of parotitis. Treatment is mostly supportive. Vaccination is the best way to prevent mumps.
Category: Infectious Diseases Mumps is a vaccine preventable, viral illness known to cause parotitis. The virus reproduces in the upper respiratory tract and is spread via saliva, oropharyngeal secretions and respiratory droplets.
Category: Infectious Diseases Measles cause Koplik spots that are a temporary viral enanthem and are pathognomonic. Fever is high grade and tends to last for about 4 days and occurs concurrently with conjunctivitis, coryza and cough.
Category: Infectious Diseases Measles causes prodromal symptoms, including high fever, malaise, conjunctivitis, coryza and cough. Koplik spots, small white to gray spots on the buccal mucosa opposite the lower molars, may appear 2-3 days before the viral exanthem.
Category: Infectious Diseases Measles, which as a 7- to 21-day incubation period, is a highly contagious, vaccine preventable, viral illness characterized by a high fever, cough, coryza and conjunctivitis followed by a maculopapular rash.
Category: Infectious Diseases Amebiasis symptoms include fever, malaise, abdominal pain, weight loss and bloody diarrhea. These amebas can cause flask-shaped ulcers in the colonic mucosa and rarely, large granulomatous masses (amebomas).
