Findings from a new study are providing important insights into the spread of Rocky Mountain spotted fever, which is transmitted from dogs to people through ticks. The new data are being used to create models that could help predict, and possibly prevent, future outbreaks. If not treated within the first five days, Rocky Mountain spotted fever can cause serious organ damage in humans that may lead to death. It can cause serious illness in dogs if not treated during the early stages. Although the disease is usually carried by the American dog tick or Rocky Mountain wood tick, the brown dog tick was identified as a new vector -; or carrier -; during a 2003 outbreak in Arizona. Since then, the Rickettsia rickettsii bacteria that causes the disease has spread to brown dog ticks across the American Southwest and parts of Mexico. Although the tick is present across the entire U.S., only those in Arizona and the surrounding regions are known to carry R. rickettsii . To better un

The official list of Covid-19 symptoms has been expanded to include nine new signs of illness. The symptom list was updated on the same day free coronavirus tests were scrapped across England, and in the midst of cases rising across the UK. The extension of the symptoms list to include ailments such as sore throat, fatigue and headache could help to reduce infections, one expert said. What are the new Covid symptoms? Until recently, the UK list had just three symptoms. It is understood that the Government's Chief Medical Officer would have needed to sign off on the expanded list of symptoms. According to nhs.uk the signs of Covid-19 that people should look out for also include: Shortness of breath Feeling tired or exhausted An aching body A headache A sore throat A blocked or runny nose Loss of appetite Diarrhoea Feeling sick or being sick A note on website adds: "The symptoms are very similar to symptoms of other illnesses, such

Show Caption Hide Caption The flu pandemic at the Jersey Shore A look back at the influenza pandemic of 1918 to 1919 and how the Shore responded. Ryan Ross and Erik Larsen, Asbury Park Press Kevin Basca was sick for days with a cough, body aches, headache and fever, but it was not until he was struggling to breathe that he headed to the nearest emergency room. "I couldn't catch my breath, and I felt like I was underwater," said the 40-year-old Pine Beach resident. Basca said hospital staff diagnosed him with pneumonia after his weeklong illness and said he was negative for COVID-19. He is one of the thousands of patients in New Jersey who have visited doctors offices, urgent care centers and hospitals in recent weeks for flu-like symptoms. Across the state, doctors are reporting a later-than-usual fl

T he Centers for Disease Control and Prevention announced late Thursday that a person in Colorado has tested positive for an H5 bird flu virus — the first such recorded infection in the United States. The CDC did not reveal the neuraminidase subtype of the virus — the N portion of an influenza A virus' name. The country is currently experiencing an unprecedented outbreak of H5N1 bird flu in both wild birds and in commercial poultry flocks. The man, described by Colorado health officials as being younger than 40 years old, experienced only fatigue; he is now in isolation and being treated with the flu antiviral oseltamivir. A statement from Colorado's Department of Public Health and Environment said he is incarcerated at a state correctional facility and was culling poultry as part of a pre-release employment program. The CDC described the poultry outbreak as presumptively having been caused by H5N1. "We want to reassure Coloradans that the risk to them i

Cholera is caused by the bacterium Vibrio cholerae , a waterborne pathogen that infects the gut of humans through contaminated water and food. When ingested, V. cholerae colonizes the gut's inner surface, causing a watery diarrhea, that if left untreated, can lead to severe dehydration and death. Cholera is still a problem, especially in less-developed or crisis-hit regions. The WHO reports that the ongoing seventh cholera pandemic is still responsible for up to four million infections, and up to 143,000 deaths each year. Horizontal gene transfer Only a few strains of V. cholerae can cause pandemic disease, with most being harmless aquatic organisms. This is because the pandemic strains have acquired specialized "toolboxes" of genes and other genetic elements called "pathogenicity islands," which can turn the bacterium into a pathogen. Strains that cause cholera pandemics have acquired pathogenicity islands through a process known as "horizontal g

Vaginal itching can be a symptom of many conditions. It could be caused by something like vaginal dryness or chemical irritants, such as the ones found in scented soaps. Itching can also be the result of a yeast infection, bacterial vaginosis, a sexually transmitted infection (STI), or something else. There are many home remedies for an itchy vagina, but the remedy you choose will depend on the cause of the itch. For example, if there's an itch inside your vagina, it could be a yeast infection. If the itch is on the skin around the vagina, it could be caused by eczema or another skin condition. It's important to know when to see a doctor, but in the meantime, here are 10 home remedies for vaginal itching. Baking soda bath Baking soda baths can potentially treat yeast infections as well as certain itchy skin conditions. According to a 2012 study, baking soda has antifungal effects. A 2014 study found that baking soda killed Candida cells, the same cells that cause yeast infecti

The agency has calculated that 15 million people have died as a result of the pandemic, far more than earlier estimates, but has yet to release those numbers. An ambitious effort by the World Health Organization to calculate the global death toll from the coronavirus pandemic has found that vastly more people died than previously believed — a total of about 15 million by the end of 2021, more than double the official total of six million reported by countries individually. But the release of the staggering estimate — the result of more than a year of research and analysis by experts around the world and the most comprehensive look at the lethality of the pandemic to date — has been delayed for months because of objections from India, which disputes the calculation of how many of its citizens died and has tried to keep it from becoming public. More than a third of the additional nine million deaths are estimated to have occurred in India, where the government of Prime Minister Narendra

These symptoms of anxiety can include: breathing fast chest pain or pressure difficulty sleeping dizziness or lightheadedness feeling hot or cold nausea difficulty focusing shaking sweating muscular weakness thoughts of impending doom Yes. In some rare cases, anxiety symptoms may lead to a rise in body temperature. This is sometimes referred to as psychogenic fever, or a fever caused by psychological reasons. Although more research on humans is needed, some human and animal studies and case reports from 2014 , 2020, and 2021 suggested that acute stress can sometimes lead to fever. A 2015 research review of both animal studies and human case reports indicated that exposure to stress raises body temperature. The average body temp

When people with asthma get viral infections, it can increase their risk of getting asthmatic bronchitis. This is a condition where a person with asthma develops acute bronchitis. Typically, acute bronchitis will go away within a week. However, chronic bronchitis does not go away and can cause severe problems for someone with asthma. This article will review the causes of acute bronchitis, what signs to look out for, and the difference between acute and chronic bronchitis. Roberto Jimenez Mejias / Getty Images What Is Asthmatic Bronchitis? Asthma is a lung condition that causes bronchioles or airways to become inflamed. When this happens, they narrow, making it harder to breathe. Bronchitis is very similar to asthma. It causes inflammation in your bronchioles, but there is a build-up of mucus that also causes them to narrow. The two types of bronchitis are acute and chronic. Acute bronchitis is caused by a viral or bacterial infecti

A normal body temperature fluctuates, but most adults should have a temperature of at least 97.8 degrees Fahrenheit. Hypothermia, or dangerously low body temperature, is diagnosed when someone's temperature dips below 95 degrees. Your body temperature can drop if you're exposed to the cold or if you have certain medical conditions. Older people naturally have lower body temperatures. This article will cover what body temperature is too low, how to take your temperature, and when to seek help.  izusek / Getty Images Normal Body Temperature Range A normal body temperature is 98.6 degrees. However, lots of factors can affect temperature. A normal body temperature can range between roughly 97.8 degrees and 99.1 degrees. Why Does Body Temperature Fluctuate? If you take your temperature frequently, you'll likely get different readings. Your temperature fluctuates throughout the day based on hormonal and metabolic cha
