Health officials declare hepatitis An outbreak in L.A. County

Health officials declare hepatitis An outbreak in L.A. County
Los Angeles County health officials declared a hepatitis A outbreak Tuesday, days after a public health emergency was announced in San Diego County, where at least 16 people have died of the highly contagious virus.
Case numbers are still small in L.A. County, with only 10 people infected as part of the outbreak, said Dr Barbara Ferrer, director of the L.A. County Department of Public Health. By comparison, almost 450 people have contracted the virus in San Diego.
Ferrer said the department is ramping up prevention efforts locally so more people don’t get sick. San Diego’s outbreak has already spread to Santa Cruz, where 69 people have been diagnosed.
Officials say homeless people in California are most at risk because the virus appears to be moving from person to person within that community. People become infected with hepatitis A, which affects the liver, by ingesting the faeces of someone who’s infected, often through contaminated food or sexual contact.
San Diego’s outbreak appears to be fueled by poor sanitary conditions, with many cases among people who used shared restrooms in jails or shelters.
Ferrer said L.A. health workers will inspect homeless encampments in Los Angeles to improve sanitation while spreading the word about improved hygiene. The city of Los Angeles is already cleaning the streets on skid row with bleach, a practice San Diego adopted earlier this month in an effort to reduce disease transmission.
She also said they’re aiming to distribute 40,000 vaccinations of hepatitis A to homeless people in L.A. County. They’re also providing shots to new jail inmates, active drug users and medical providers.
“We are very early in an outbreak and the more people who get vaccinated in the high-risk populations ... the smaller the outbreak will end up being in L.A. County,” Ferrer said. “This is, in fact, a disease that’s preventable.”
The efforts will continue for months, she said, as San Diego officials expect their outbreak to persist into next year.
Los Angeles County health officials said that before this week, they had already counted eight patients infected with hepatitis A. Five had recently travelled to San Diego or Santa Cruz, where they were probably exposed, officials said. Three other people were infected at a healthcare facility where one of those five was being treated.
But Tuesday, officials said they had diagnosed two people who appear to have been infected locally, triggering the outbreak declaration. The two new cases involved homeless people who had not travelled to a place with an outbreak, Ferrer said.
“The outbreak label isn’t meant to scare people,” said County Supervisor Sheila Kuehl at Tuesday’s county supervisors meeting. “It isn’t suddenly that was rife with hep A cases here.”
Dr Sharon Balter, L.A. County public health department’s director of acute communicable disease control, said an outbreak of hepatitis A is the homeless community is especially concerning because many have underlying health conditions.
Most people recover from hepatitis A on their own, but it can be seriously harmful to people with other liver conditions, including hepatitis B or C. Approximately 4% of infected patients in San Diego has died, a significantly higher proportion than the typical 1% mortality rate for the disease, she said.
“This particular population is particularly vulnerable,” Balter said.
Should you get vaccinated?
Though the current outbreak is centred in the homeless community, anyone can contract hepatitis A. Each year in L.A. County there are 40 to 60 people infected by the virus, which is often transmitted through contaminated food.
One of the 10 people in L.A. County infected in the ongoing outbreak worked at a fruit stand in Lancaster and may have passed on the virus. The only outbreak in the past 20 years in the United States bigger than San Diego’s was caused by green onions served at a Pennsylvania restaurant that sickened more than 900 people.
It typically takes about three weeks to notice symptoms, which include vomiting, fever, yellowing of the eyes or skin, joint pain and dark urine. There’s no specific treatment for hepatitis A, but for most people, symptoms usually don’t last more than two months.
Health officials reminded people not to share food, drinks or cigarettes with people, and to wash their hands with soap after using the bathroom and before handling food.
Ferrer said people who are concerned about the outbreak should ask their doctor about the vaccine, which is already recommended for children.

“If you’re older than 18 and you haven’t been vaccinated, this might be a good time for you to get vaccinated,” Ferrer said.

Breast cancer charities: How to make an impact

Breast cancer charities: How to make an impact With thousands of charities competing for donations, it can be difficult to know where a financial gift to a good cause will make the biggest impact. This article outlines the top  breast cancer  charities in the United States and their specific contributions to the cause, plus other factors to keep in mind before donating. The history of the pink ribbon The pink ribbon is a symbol of breast cancer and is often sold to raise money for breast cancer charities. Breast cancer activist and survivor Charlotte Hayley inspired the design of the pink ribbon, which is still in use today. Hayley initially handed out peach-coloured looped ribbons that she made herself with a card stating: "The National Cancer Institute's annual budget is $1.8 billion, only 5 percent goes for  cancer  prevention. Help us wake up our legislators and America by wearing this ribbon." In 1991, the Susan G. Komen Breast Cancer Foundati...

Lung cancer and cough: What is the connection?

Lung cancer and cough: What is the connection? Everyone has experienced a nagging cough after a cold or needed to cough while in a quiet room. Despite these problems, coughing actually serves a very valuable and useful purpose. Coughing is a protective action, helping the lungs clear out potential germs or harmful objects.  Sometimes, however, that cough is not linked to a cold or infection and can linger for weeks to months at a time. This may lead people to wonder or worry that their cough is a sign of something more serious, such as  lung cancer . This article takes a look at the connection between coughing and lung cancer, including when someone should see a doctor. Coughing and lung cancer A cough associated with lung cancer may be either dry or wet. Not every a cough signifies the presence of lung cancer.

For people with Type 2 diabetes, there is an additional incentive for keeping the disease under management

For people with Type 2 diabetes, there is an additional incentive for keeping the disease under management  Research shows a possible link between diabetes and cognitive decline, including increased risk for Alzheimer’s disease and vascular dementia. The scientific reason behind the link between diabetes and brain health is complex. Some scientists believe people with diabetes may also have insulin resistance or insulin deficiency that could damage brain cells enough to cause memory loss. Studies are underway to understand why 80 percent of people with Alzheimer’s disease also have some form of diabetes or disturbed glucose metabolism. However, so far, longitudinal research has not produced a consensus view regarding the link between blood glucose levels and cognitive impairment. Meanwhile, in South Florida, medical professionals are working with diabetic patients to minimize the risk of cognitive decline through a variety of methods that include lifestyle, medical and mental-...
