Ebola Virus Disease

Molluscum contagiosum is a skin infection caused by a virus of the same name. It produces benign, raised bumps, or lesions, on the upper layers of your skin. The small bumps are usually painless. They resolve without treatment and rarely leave scars. The length of time the virus lasts varies for each person, but the bumps can remain from 2 months to 4 years. Molluscum contagiosum ( M. contagiosum ) transmits between people through direct skin contact with someone who has the virus or by touching an object that the virus has contaminated, like a towel or a piece of clothing. Medication and surgical treatments are available, but you won't need them most of the time. The virus can be more difficult to treat or cause more severe effects if you have a weakened immune system. In this article, we explain the symptoms, causes, and treatments for molluscum contagiosum. If you or your child comes into contact with the M. contagiosum virus, you may not see symptoms of infection for up to 6 ...

Vaginal discharge is normal and helps the vagina cleanse itself. Yellow discharge can occur when healthy, normal discharge (which is initially clear mucus) comes into contact with the air and turns white or yellow. Discharge may also be yellow as it passes through the vaginal walls, from microbes normally present in the vagina (vaginal flora), from vaginal fluid, or from a small amount of blood still present after menses. But a dark-yellow discharge may be a sign of infections that require treatment by a doctor. Learn more about the causes of yellow vaginal discharge and how to treat it. Phynart Studio / Getty Images What Is Yellow Discharge Discharge from the vagina is normal, and it can happen at any time throughout the menstrual cycle. Normal discharge that is not a cause for concern is: White Transparent Odorless Thick to thin Discharge that is clear may turn yellow upon contact with the air or other interactions with...

Fig. 1: The T6SS gene clusters of the classical V. cholerae strain PA1849. A Illumina-generated reads were mapped to a 6th pandemic classical strain (O395) and a 7th pandemic El Tor V. cholerae strain (C6706). Read coverage plotted against the nucleotide sequence of the three T6SS gene clusters (shown as light blue arrows in panel (B)) separated by white vertical lines that indicate the intervening genomic sequences not included in this analysis. The top plot (gray) represents read coverage against the O395 reference, and the bottom plot (gray) represents read coverage against the C6706 reference. B Nucleotide alignment of the three T6SS clusters (bottom light blue arrows) from PA1849, O395 and C6706. The top black bars, representing the PA1849 T6SS clusters, are designated as the reference sequences. Conserved residues in O395 and C6706 sequences are represented by gray bars with single-nucleotide polymorphisms (SNPs) high...

Meningitis refers to inflammation around the brain and spine, often due to viral or bacterial infection. The infection causes swelling in the meninges, which are thin layers of tissue around the brain and spinal cord. If untreated, meningitis can be life threatening. Pediatric meningitis describes the disease's effects in infants, children, and teens. Meningitis can occur in people of all ages, but newborns and people with weakened immune systems are at an increased risk. Two key vaccines, MenB and MenACWY, protect against strains of bacterial meningitis, the most dangerous kind. The Centers for Disease Control and Prevention (CDC) recommends these vaccines for all kids 11 to 12 years old, with a booster later. They also recommend the Hib vaccine for all kids under 5 years old. This vaccine has been very effective at reducing meningitis mortality rates in children. We'll go over how to recognize the signs of meningitis in different age groups, what treatment methods are avail...

Lupus is a chronic autoimmune condition in which the immune system becomes overactive and attacks healthy tissue. It most often affects the heart, joints, skin, lungs, blood vessels, kidneys, and central nervous system. Lupus can also result in damage to the eyes and the area around them, which may cause vision problems. Lupus is a complex autoimmune condition that affects about 1.5 million people in the United States. Although lupus most commonly affects the skin, joints, and internal organs, it can affect many parts of the body, including the eyes. Some people may even refer to lupus as "the disease with 1,000 faces," as it can produce a wide variety of symptoms. Lupus can affect anyone, but some people have a higher risk of developing the condition. Evidence notes that females aged 15–44 years, people belonging to certain racial groups, and those with a family history of autoimmune disease are at the highest risk. There are four main types : Systemic lupus erythematosus (...

The kidneys remove waste and extra fluid from your body and help maintain proper levels of various minerals. Without correct levels of nutrients, nerves, cells, muscles, and organs may not work properly. When your kidney function goes below 15% of normal, it's classified as kidney failure. It might be preceded by kidney disease. The symptoms that occur are typically a result of waste buildup. There are treatments for kidney failure, and your healthcare provider can go over which treatment is best for you. This article will review the symptoms of kidney failure. Knowing what the symptoms are can help you recognize warning signs early so you can see your healthcare provider about any concerns. ljubaphoto / Getty Images Frequent Symptoms Signs of kidney failure can vary, and sometimes it's difficult to notice them at first. Early symptoms can include: Headaches Itchiness Swelling, especially in the ankles, legs, and fee...

The final months of 1918 provide a sobering answer. An influenza pandemic began ravaging the state in the fall of that year — ultimately killing more than 10,000 Minnesotans. Meanwhile, young men were being ...

Scleroderma, or systemic sclerosis, remains the most challenging rheumatic disease to treat and holds the highest mortality rate. This review explores the unique pathophysiology, clinical features, and therapeutic approaches to this systemic connective tissue disease. During my near half-century of rheumatology practice, I found that scleroderma, or systemic sclerosis, to be the most challenging rheumatic disease to diagnose and manage. Its pathogenesis is less well-understood than other systemic connective tissue diseases – such as systemic lupus erythematosus (SLE) or rheumatoid arthritis (RA) – and this gap has impeded development of effective therapies. Further impacting management is the fact that systemic sclerosis (SSc) presents in a variety of ways, often resulting in consultation with myriad specialists, diagnostic confusion, and treatment delays. In this review, the many presentations of SSc will be illustrated with hypothetical case examples, as a means to exploring the di...
