A viral rash can be caused by an immune system overreaction or toxins released by a virus. It can vary in characteristics and may require specific treatment. Young children are prone to viral rashes, and some viruses can present a risk to health. Treatment may include steroids, topical ointments, and calamine lotion. The smallpox virus […]
Viral load (LV) measures the amount of virus in body fluids and is used to monitor diseases such as HIV-1. Successful therapies see a decrease in LV within six months, and LV testing allows for earlier detection than antibody testing, which could prevent the spread of HIV. Low-cost LV tests are being pursued for worldwide […]
Viral load tests count the number of virus copies in a patient’s blood to determine the severity of an infection. They are used for HIV, hepatitis B and C, and cytomegalovirus. Consistent testing methods are important, and undetectable results do not mean the virus is eradicated. Testing is used to monitor treatment effectiveness. A viral […]

Viral vectors are viruses modified in a lab to introduce genetic material into cells for therapeutic treatments, gene therapy, and research. Adenoviruses, retroviruses, herpesviruses, and lentiviruses are popular choices. They can be modified to target specific cells and have potential bioterrorism uses. Creating a single vector can take time and genetic markers can be used […]
Meningitis is an infection of the meninges, with viral meningitis caused by a virus and bacterial meningitis caused by bacteria. Bacterial meningitis is more severe and requires immediate hospitalization and treatment with antibiotics, while viral meningitis usually resolves without treatment. Symptoms are similar for both types and can include headaches, high fevers, and stiff necks. […]
