Causes of Schistosomiasis

Dyshidrotic eczema is a type of eczema that produces skin blisters on the feet and hands. Many people call these small blisters summer finger bumps. People may also refer to dyshidrotic eczema as dyshidrosis, pompholyx, foot-and-hand eczema, vesicular eczema, or palmoplantar eczema. The blisters or bumps that form can be uncomfortable and painful, but they are not permanent. Dyshidrotic eczema involves flare-ups that last several weeks. Below, we look at the symptoms, causes, risk factors, and treatment options for dyshidrotic eczema, as well as how diet may impact this condition. Doctors sometimes call dyshidrotic eczema "pompholyx eczema." Pompholyx is the word for "bubble" in Ancient Greek. The condition produces painful, itchy blisters on the hands and feet. Water-filled blisters can appear on the fingers, palms of the hands, soles of the feet, and toes. People with this type of eczema may also have other types of eczema elsewhere on the body.

Colitis is an inflammation of the lining of the colon. Many conditions can cause colitis. If a person has colitis, they will have abdominal pain, discomfort, and diarrhea. People with colitis may experience mild chronic pain or severe and sudden pain. There are different types of colitis, and many have overlapping symptoms. This article looks at colitis, different types of colitis, causes, symptoms, and treatments. Colitis is an inflammation of the colon's lining. The large intestine can become inflamed for several different reasons. The most common causes typically include infection, such as: Both Crohn's disease and ulcerative colitis form the two major types of IBD. This condition typically affects people between 15–35 years of age, and then there is a second peak of the condition in people between 60–70 years of age. Colitis is often chronic, and there is no known cure. However, a person can receive treatment for the condition and effectively manage it. There are several t

The most common cause of a circular rash on the skin is ringworm, but other issues can also leave this distinctive mark. A doctor diagnoses the cause of a rash after examining it and asking about symptoms. They may recommend oral medication, a topical cream, or strategies for avoiding triggers. In this article, learn more about the issues that can cause this rash and how to treat them. Despite its name, ringworm is a fungal skin infection — it is not caused by a worm or any other parasite. The infection got its name because it causes a rash that is usually circular, with a thin raised ring around the edge that may look like a worm. Symptoms The circular rash may initially measure a few centimeters across, and it can grow without treatment. It may look like a round, flat patch, and the middle of the rash tends to heal first. On lighter skin, a ringworm rash is red or pink, and on darker skin, it is silver or brown. The skin around the rash may be dry or scaly, and the rash can be extrem

Epidemiological profiles The prevalence of C. sinensis infection and the proportion of persons ingesting raw freshwater fish refer to Additional file 1: Table S1 [17, 19]. The epidemiological profiles of C. sinensis prevalence and raw-freshwater fish-eating practice were similar in different endemic levels, namely higher prevalence of C. sinensis and proportion of raw-fish-eating practice in male compared to female and in elder people compared to children. Overall, the DALYs per 1000 was 6.4, ranging from 0.2 to 34.3 in different counties. It was 0.5 in children ranging from 0 to 7.3, 4.6 in adult female ranging from 0 to 26.0, and 10.5 in adult male ranging from 0.2 to 42.9 (Additional file 1: Table S2). In adult female, the YLDs per 1000 was 4.3 and the YLLs per 1000 was 0.3. In adult male, the YLDs per 1000 was 9.7 and the YLLs per 1000 was 0.8. Cost effectiveness In very high prevalence group, cost to treat single infected case in selective chemotherapy was USD 10.6 in adult mal

The NHS still lists a high temperature, a new continuous cough, and a loss of change to sense of smell or taste have been considered as the main signs of coronavirus infection. However, as more Omicron cases have emerged, several other symptoms have surfaced which could indicate Covid-19 infection - including three warning signs that can show on your skin. People who have tested positive for Omicron have reported getting skin rashes (Composite: Mark Hall / JPIMedia) What effect does Omicron have on the skin? Some people who have tested positive for Omicron have reported getting three different types of skin rashes. These include hives, prickly heat and chilblains, all of which can cause the skin to become red and itchy. Hives Hives can occur in different shapes and sizes, but will usually cause raised spots and red patches to appear on the skin, and can occur anywhere on the body. The rashes will often be itchy and can sometimes cause a stinging sensation. It will usually settle down w

Source: GeoHealth More than half a million children under 5 years old die of diarrheal disease every year, according to the World Health Organization. Deaths and serious illness are most common in regions without access to clean water. Local climate fluctuations can be tied to outbreaks, but researchers have struggled to predict how climate change will affect diarrheal disease prevalence because diarrhea does not have a single root cause. Bacteria, viruses, and protozoa are all potential culprits of the underlying intestinal infection. Each potential cause can react differently to changes in rainfall, temperature, and other climate variables. New research by Colston et al . aims to shed light on how different pathogens could respond to climate change. Researchers analyzed how 10 different diarrhea-causing bugs— including bacteria like Escherichia coli and Campylobacter , as well as viruses like adenovirus, norovirus, and rotavirus—responded to eight climate variables.

Whiteheads and other small white bumps on the penis are common and usually harmless. White bumps on the penis may be pimples related to acne, pearly penile papules, or bumps called Fordyce spots. However, white spots can also be related to some sexually transmitted infections (STIs) and may require treatment. This article will look at some possible causes and treatments of whiteheads and other bumps on the penis. Whiteheads are a common form of acne. They are more common on areas of skin with lots of pores, such as the face, chest, and back, but they can also occur on the penis. When they occur on the penis, they are more common on the base or the shaft. Whiteheads develop when a pore becomes clogged with the skin's natural oil, called sebum, along with sweat, dead skin, and other debris. When bacteria get into the pore, they can ca

What Is the Treatment for Lice? Head Lice Getting rid of head lice involves the use of over-the-counter treatments or prescription medications, typically in conjunction with combing the hair with a special comb. In some geographical locations, lice are resistant to certain treatments. Ask your doctor if your area has resistant lice so that you can be sure to get the most effective treatment. Some prescription and over-the-counter treatments kill both the live lice and their eggs, also called nits. Other products require two applications, approximately 7 to 9 days apart. Check the label to see if the product kills both lice and eggs, and how to use it correctly. Over-the-counter products with pesticides include: Pyrethrins are a common treatment that is available over the counter. Some studies suggest pyrethrins can affect cognitive development in children. More research is needed. Brand names include A-200, Pronto, Rid, Triple X, and Xeglyze. For best results, follow the direc

Increasing numbers of antibiotic resistant bacterial infections in South Africa and across the world are everybody's problem. The loss of working antibiotics affects how we may need to treat you for what used to be straightforward everyday infections, how we prevent you getting infected when you need treatment for cancer, transplantation, HIV and other immune suppressing illnesses. It also threatens your chances of having a successful surgery if more wounds become infected and can't be treated. The dramatic global increase in antibiotic resistant bacterial infections has led to rallying cries to 'fight' back and wage 'war' against antibiotic resistant bacteria. But fighting bacteria is definitely the wrong strategy. Here's why: Bacteria and other microorganisms comprise the earliest life on Earth, found as microfossils in Australian rocks dating back 3.5 billion years. Bacteria (and fungi) in soil produce antibiotics, chemicals that give ba

Giardia infection is one of the most common causes of waterborne disease in the United States. Clinical Pearl of the Day: Giardia Infection Giardia infection is an intestinal infection marked by stomach cramps, bloating, nausea, and bouts of watery diarrhea. Insight : Giardia infection is caused by a microscopic parasite that is found worldwide, especially in areas with poor sanitation and unsafe water. Giardia infection (giardiasis) is one of the most common causes of waterborne disease in the United States. The parasites are found in backcountry streams and lakes but also in public water supplies, swimming pools, whirlpool spas, and wells. Giardia infection can be spread through food and person-to-person contact. Giardia infections usually clear up within a few weeks. Symptoms include watery stool, fatigue, stomach cramps, gas, nausea, and weight loss. Causes may include swallowing contaminated water, eating contaminated food, and person-to-person contact. Risk factors include bei

The former president began fighting the disease in 1986 when it affected 3.5 million of the world's most vulnerable people. Guinea worm infections dropped to just more than a dozen worldwide last year, getting closer to fulfilling former President Jimmy Carter's dream of completely eradicating the disease during his lifetime. The Carter Center reported on Wednesday that only 14 human cases of Guinea worm disease were reported in all of 2021, the result of years of public health campaigns to improve access to safe drinking water in Africa. People who drink unclean water can ingest parasites that can grow a metre (three feet) long before painfully emerging from the skin. The Atlanta-based centre founded by Carter and his wife, Rosalynn, said the remaining infections occurred in just four countries in sub-Saharan Africa; Chad, Sudan, Angola, and Cameroon. That is a decline of nearly half compared with the previous year, when 27 cases were reported in seven African countries.

Eczema Dyshydrotic eczema on foot. Iuliia Mikhalitskaia / Getty Images  Eczema (atopic dermatitis) is an umbrella term for a group of conditions that involve skin inflammation. They all cause red, scaly patches that itch a lot. The cause is unknown. Researchers think genetics and environmental factors both contribute. Dyshidrotic eczema forms on the tips or sides of your toes and fingers. It's intensely itchy. It also causes red, scaly areas of cracked skin with tiny blisters. Everyone has different triggers for eczema outbreaks. Typical triggers include: Irritation from staying damp Overly dry skin from excess heat and low humidity  Eczema is treated with topical skin creams and ointments. They rehydrate skin, balance the skin's pH (acidity), and protect skin from dryness and sweat. Topical corticosteroids can help with inflammation. Recap Eczema is a group of conditions that cau

Roundworms are a parasitic group of organisms causing infestation in the human body. Ascariasis, hookworms and pinworms are the most common roundworms in the body. They live, grow and utilise nutrients from the human body. What causes a roundworm infection? Roundworm eggs live in faeces-contaminated soil. Animals can transmit roundworms as well. If a child swallows a roundworm egg, it passes down to the intestine and hatches into larvae. Larvae get into the bloodstream and travel to different parts of the body through the lungs, up to the throat. They are then swallowed again and return to the intestine where they grow into adult worms, and come out through faeces. Roundworms can live in the small intestine for years. Most of the time, children do not exhibit any symptoms. When parents discover worms in their child's stool, they know he or she has worms. Signs and symptoms Most children with roundworm infections do not have any signs and symptoms. Some can have stomach pa

Pityriasis rosea (PR) is a benign rash that usually begins as a large circular or oval spot on your chest, abdomen, or back. The circular patch known as the herald patch can be up to 4 inches wide. These kinds of patches are often triggered by a viral infection, mostly among children and young adults. The patches are widespread, minimally itchy, skin rash on the abdomen, back upper, legs and upper arms. It may appear 4-5 days after the onset of the symptoms and continue to appear for a while.

An infection rate higher than any previously recorded anywhere in the country for "the dangerous and rare" deer tick virus has been found in ticks in a Pennsylvania park. The Pennsylvania Department of Environmental Protection reported Thursday that its Vector Management Program detected "an unusually high infection rate" deer tick virus – a type of Powassan virus – in samples of adult ticks recently gathered in Lawrence Township Recreational Park near Clearfield in Clearfield County. Transmitted by blacklegged ticks, also called deer ticks, DTV is a type of Powassan virus, which is rare in the U.S. but has been increasing in recent years. It can be transferred from tick to human within 15 minutes of a tick bite and can result in encephalitis or meningitis and hospitalization, and death in about 12 percent of people with the severe form of the disease. Other tick-borne diseases, such as Lyme disease, take much longer to cause infection, typically 24 hours or more af

在金县出现了汉坦病毒病例的报告 (simplified Chinese)   在金縣出現了漢坦病毒病例的報告 (traditional Chinese) Se ha registrado un caso de hantavirus en King County (Spanish) Hantavirus can cause a rare but deadly disease called Hantavirus Pulmonary Syndrome (HPS). Hantaviruses are a group of viruses (germs) carried by rodents, and Sin Nombre virus is the type found here. As the weather turns colder and rodents seek shelter from the elements, residents of King County should remain aware of hantavirus and safety measures to prevent exposure. HPS is rarely identified in Washington state, with only 45 cases reported since 1997, mostly in eastern Washington. Since 1997 there have been eight cases of HPS in King County, including a recent case we are currently investigating in an adult resident of southeast King County, who was hospitalized in December 2021 and is now recovering. The patient reported likely exposure to a mouse infestation. Of these eight cases, five
