CDC issues guidelines for pregnant women during Zika outbreak

CHICAGO (Reuters) – The U.S. Centers for Disease Control and Prevention on Tuesday issued guidelines for doctors caring for pregnant women during the Zika outbreak, a mosquito-borne illness linked with microcephaly marked by unusually small head size and brain damage.

The new guidelines urge doctors to ask their pregnant patients about their travel history to areas with Zika virus transmission.

Women who had traveled to regions in which Zika virus is active and who report symptoms during or within two weeks of travel should be offered a test for Zika virus infection. Pregnant women who had no clinical symptoms associated with the infection such be offered an ultrasound to check the fetus’ head size or check for calcium, two signs of microcephaly.

Trader Joe’s recalls cashews amid salmonella concerns

A possible salmonella contamination has prompted Trader Joe’s to recall some cashews.

The grocery store chain issued a statement about the recall late last week, saying that one particular kind of Trader Joe’s Raw Cashew Pieces could be contaminated with the bacteria.

The cashews are marked “BEST BEFORE 07.17.2016TF4,” the company said, and were distributed to stores in 30 states across the country, as well as the District of Columbia.

It wasn’t clear exactly how many packages were included in the recall.

Trader Joe’s said it learned of the possible contamination from a supplier, but didn’t elaborate.

A recall notice on the Food and Drug Administration website says Heritage International (USA) Inc. was voluntarily recalling the cashew lot after routine lab tests found salmonella in it.

The bacteria can cause people to fall ill.

Trader Joe’s said it hasn’t received any reports of anyone getting sick from the cashews, though it has stopped selling all Trader Joe’s Raw Cashew Pieces in its stores pending an investigation.

The grocery chain encourages anyone who bought the cashews marked “BEST BEFORE 07.17.2016TF4” to return them for a full refund or throw them out without eating them.

According to the CDC, salmonella sickens about 1.2 million Americans every year. Symptoms include diarrhea, fever and abdominal cramps, and most people fully recover in 4 to 7 days. In extreme cases, though, infections can spread beyond the intestines and become more severe.

The bacteria leads to about 450 deaths and 19,000 hospitalizations every year, the CDC says. Children, older adults and people with weak immune systems are particularly at risk.

Hawaiian child born with birth defect was infected with Zika virus

A Hawaiian child who was recently born with a rare birth defect called microcephaly had been infected with the mosquito-borne Zika virus, the state Department of Health announced.

Officials made the announcement on Friday, the same day the Centers for Disease Control and Prevention (CDC) issued updated travel warnings for regions where Zika outbreaks are present.

The Zika virus usually only causes a mild illness and most people typically recover in a week, the CDC says, but the virus is collecting global attention because scientists are currently working to see if it is responsible for causing birth defects such as the one found in the Hawaiian child.

According to the CDC, children born with microcephaly have smaller-than-usual heads, and the defect may lead to other issues such as seizures, developmental delays and vision problems.

The Brazilian Ministry of Health reported a significant rise in the birth defect since the virus arrived in May. The country used to see fewer than 200 cases per year, but now has about 3,500.

The Hawaiian baby’s mother was living in Brazil last May, the state Department of Health said in a news release, and likely transmitted the virus to her child while he or she was in the womb.

Microcephaly can be caused by a variety of issues including genetic changes, malnutrition, alcohol exposure and certain kinds of infections, according to the CDC, but it’s still a relatively rare defect and only surfaces in about 2-12 babies out of every 10,000 born in the United States.

“We are saddened by the events that have affected this mother and her newborn,” Hawaii Department of Health State Epidemiologist Sarah Park said in a statement.

Hawaii health officials said neither the mother nor the child are currently at risk of transmitting Zika, nor were they ever at risk of spreading the virus throughout Hawaii. The country has yet to see a locally contracted case of Zika, the CDC has said.

However, the Hawaii Department of Health reported six people have gotten infected while visiting foreign countries and returned to the state.

The CDC on Friday sent out updated travel notices for Puerto Rico, Mexico, Central America, South America and the Caribbean, where Zika is found in local mosquitos, asking travelers — especially pregnant women — to “practice enhanced precautions” to prevent mosquito bites. Previously, the CDC had only been asking travelers to “practice usual precautions.”

There isn’t any vaccine against a Zika infection, the CDC says.

“The virus is spreading fairly rapidly throughout the Americas,” Dr. Lyle Petersen, the director of CDC’s division of vector-borne diseases, told reporters during a Friday evening news briefing, according to a transcript posted on the CDC’s website. “We know in populations that it does affect, a large percentage of the population may be become infected. And because of this growing risk of or growing evidence that there’s a link between Zika virus and microcephaly, which is a very severe and devastating outcome, it was important to warn people as soon as possible.”

Petersen told the news briefing that the CDC recently found its “strongest scientific evidence to date” of a link between Zika and “poor pregnancy outcomes” like microcephaly, but more tests and studies were needed to determine the risks the Zika virus may pose to pregnant women.

Common symptoms of Zika include fever, joint pain and rash, the CDC says. However, Petersen told the news briefing that only 1 in 5 people infected with the virus will display those symptoms.

Petersen also told reporters there have been at least eight United States travelers who tested positive for Zika after traveling overseas in the past 15 months, compared to just 12 who tested positive for the virus between 2007 and 2014. And the CDC is also still receiving samples from people displaying symptoms, so that number could increase as more test results come back.

While the specific kind of mosquito that transmit the virus are present in parts of the United States, Petersen told reporters that improvements in housing construction, air conditioning and mosquito control have helped prevent large outbreaks of other mosquito-borne illnesses.

He told the news briefing it would be difficult to determine exactly how Zika may spread in the coming months.

“I think we’re just going to have to wait to see how this all plays out,” he told reporters. “These viruses certainly can spread in populations for some time. But, again, this is new. This is a dynamic and changing situation. I think it’s really impossible for us to speculate what may happen in three or four or even next month for that matter.”

Separately, Hawaii is dealing with another outbreak of a mosquito-borne illness.

The state Department of Health says there have been 223 cases of dengue fever since Sept. 11. It’s the first locally-acquired outbreak of the disease since 2011.

The World Health Organization says dengue, which can cause fevers, headaches, muscle and joint pains and rashes, has become increasingly common in the past 50 years — spreading to more than 100 countries and placing about half the world’s population at risk of an infection.

CDC closely monitoring emergence of new bird flu strain

CHICAGO (Reuters) – The U.S. Centers for Disease Control and Prevention is closely monitoring individuals who may have been exposed to the new strain of bird flu that has been found in a flock of turkeys in Indiana, a CDC health official said on Friday.

Dr. Michael Jhung, a medical officer at the CDC, said there is no evidence of human infection related to the new bird flu strain known as H7N8, but the agency and local health officials are not taking any chances.

“There’s always the possibility of implications to human health when you see a new flu virus in animals, like we’re seeing now in turkeys,” Jhung told Reuters in an interview.

Jhung said the CDC and local health departments are already implementing a program designed after last year’s large bird flu outbreak in poultry, and will monitor people in close contact with infected birds.

California, Minnesota Health Officials Warn of Norovirus Outbreaks

Public health officials in California and Minnesota are warning about norovirus outbreaks, cautioning that the intestinal disease could sicken lots of people in those states this winter.

The California Department of Public Health announced last week that there had been 32 confirmed outbreaks of the disease since October, a number that greatly exceeds the total reported in the same window last year. Hundreds likely fell ill from the disease, officials said.

In Minnesota, the state Department of Health cautioned that the arrival of a new strain of the disease could cause some additional norovirus illnesses this winter. The department said it has investigated at least 20 outbreaks of the GII.17 Kawasaki strain since September. The strain is the same one that spurred many outbreaks in Asia last winter, officials said in a news release.

“Every few years, a new strain of norovirus emerges and causes many illnesses,” Amy Saupe, a foodborne disease epidemiologist with the department, said in a statement. “We don’t know yet if this new strain will lead to an increase in the number of outbreaks reported, but it could.”

According to the Centers for Disease Control and Prevention (CDC), norovirus is the top cause of stomach flu in the United States. The highly contagious virus sickens between 19 million and 21 million people, hospitalizes 56,000 to 71,000 and kills between 570 and 800 every year. Common symptoms include fever, diarrhea and vomiting. Most people recover within 1 to 3 days.

People get norovirus from eating tainted food or touching contaminated surfaces, making it relatively easy for the disease to spread in places like schools, daycares and nursing homes.

The Boston Globe reported a sick employee came to a Chipotle restaurant in the city earlier this month and 136 people — including some Boston College students — fell ill. There were some initial fears that outbreak was linked to an E. Coli outbreak at Chipotle restaurants in nine states, but the paper reported health officials ultimately determined that norovirus was at fault.

The CDC and other public health officials say proper disinfection, hand hygiene and food-handling techniques are vitally important to help prevent norovirus from spreading.

“One of the most important things you can do to avoid norovirus and other illnesses this holiday season is to wash your hands frequently with soap and running water for at least 20 seconds,” Dr. Karen Smith, the director of the California Department of Public Health, said in a statement. “This is especially important after using the bathroom, changing diapers, and before preparing or eating food. Hand sanitizers are not effective against norovirus.”

Hawaii Reports Additional Cases of Dengue Fever

The number of people infected with dengue fever in Hawaii is climbing, officials said Monday.

The Hawaii Department of Health reported that it was investigating 167 total cases of the mosquito-borne illness, which can lead to fatal consequences in extreme cases. There were 122 confirmed dengue cases as of Dec. 2, signifying 45 additional infections in about three weeks.

State health officials said only three of the 167 cases are currently infectious. The other people got sick between Sept. 11 and Dec. 10, so they are no longer at risk of transmitting the disease.

The health department also reported there were 659 additional potential dengue infections that had been ruled out, either through test results or the illnesses failing to meet the case criteria.

Dengue isn’t endemic (regularly found) in Hawaii, though health officials said it can occasionally be brought in from travelers who got infected in endemic regions. But this latest outbreak on the Big Island is unique because it’s the first cluster of locally acquired cases since 2011, when Centers for Disease Control and Prevention (CDC) records indicate five people got sick in Oahu.

According to the World Health Organization (WHO), an arm of the United Nations, dengue is transmitted when an infected mosquito bites a human. The infection generates a flu-like illness — from which most people usually recover within a week — though it sometimes progresses to severe dengue. In those instances, people can suffer organ impairment and severe bleeding.

The WHO estimates severe dengue hospitalizes about 500,000 people per year, and about 2.5 percent of them die. Dengue is much more common, with some estimates indicating as many as 136 million people falling ill every year, but non-severe cases of the disease are rarely ever fatal. Symptoms can include severe headaches, swollen glands, joint and muscle pain and a high fever.

The Hawaii outbreak reflects a global trend in which dengue is spreading to new locales.

The WHO reports the disease was traditionally found in the tropics and subtropics, but it’s now endemic in more than 100 countries and about half the world’s population is at risk of infection. Still, early detection and access to good medical care keeps the mortality rate below 1 percent. Without those, the WHO says severe dengue can be fatal in more than 20 percent of cases.

Hawaii health officials say it’s still safe to visit the island. The department encourages travelers to use insect repellant and wear long sleeves and pants to help prevent mosquitos from biting.

California Woman Dies From Brain Eating Amoeba

A 21-year-old California woman is dead after falling victim to a brain eating amoeba.

Health officials would not release the name of the woman but said she likely contracted the infection while swimming on private property.  They do not believe that anyone other than family and friends who used the same body of water could be at risk.

The amoeba, known as Naegleria flowleri, thrive in warm freshwater lakes, ponds and hot springs.  The infection can take hold of a human when the amoeba travels through the nasal passages and into the brain.  Once in the brain, the amoeba will destroy the brain tissue.  The victim usually dies within 3 to 18 days.

The Centers for Disease Control says that of 133 cases in the U.S. in the last 52 years, only three people have survived infection.  The victim in this case was admitted to Northern Inyo Hospital in Bishop, California on June 16th and was diagnosed with meningitis.  When she didn’t improve, she was flown to Reno, Nevada where the CDC confirmed the deadly amoeba.

The interesting thing about the amoeba is that while it is widespread, it does not seek a human host.

“It is unknown why certain persons become infected with the amoeba while millions of others exposed to warm recreational fresh waters, including those who were swimming with people who became infected, do not,” Richard Johnson, M.D., of Inyo Public Health said in the report.

The CDC recommends that people avoid poorly maintained or unmaintained freshwater sources including pools, hot springs and ponds.

Texas Resident Dies Of Mad Cow Disease Related Illness

The Centers for Disease Control has confirmed the death of a Texas patient who contracted a disease connected to Mad Cow Disease.

The patient died from Variant Creutzfeldt-Jakob Disease.  The disease is a rare, degenerative and fatal brain disorder that is caused by the consumption of meat and other products from cows suffering from bovine spongiform encephalopathy or “Mad Cow Disease.”

The CDC said this is the fourth time Variant Creutzfeldt-Jakob Disease has been found in the United States.  The first three cases were confirmed to have contracted the virus outside the USA where the variant is more prevalent and the most recent patient had extensively traveled to Europe and the Middle East.  Most of the world’s cases have been in the United Kingdom and France.

Classic CJD is not caused by the Mad Cow Disease related agent.  In the United States, classic CJD is found in one person per 1 million residents each year.

Debilitating Illness From Africa Discovered In Americas

A virus that causes debilitating illness has been discovered in the Caribbean after previously only being identified in Africa.

A dozen cases of the chikunguya virus has been confirmed in St. Martin, and islan d in the northeast Caribbean. Health officials say that another dozen people are suspected to be infected with the virus.

The virus causes fever, rash and fatigue along with intense muscle and joint pain that can leave victims virtually incapacitated for weeks. In some cases, doctors have been able to document victims with joint and muscle pain for years.

While the disease can be debilitating, it is not fatal. It is spread through mosquitos that can also carry the deadly dengue fever virus.

There are no specific treatments for the disease and there is no vaccine available. Health officials say a few cases of the disease have been seen in Italy and France in recent years but the St. Martin cases are the first in the Americas.

The Centers for Disease Control has sent a health advisory to U.S. doctors to be alert for potential signs of the virus.

Drug-Resistant Bacteria Sickens 2 Million

The U.S. Centers for Disease Control says that 2 million Americans have been sickened by some strain of drug-resistant bacteria and around 23,000 died because their infections could not be treated.

A deputy director for the CDC’s Division of Healthcare Quality Promotion says that the overuse of antibiotics contributes heavily to the problem.

“Very recently we looked at how good antibiotic prescriptions are in this country, and about half are unnecessary or the wrong antibiotic,” Dr. Michael Bell told CNBC. “That’s a lot of room for improvement.”

Federal officials are attempting to spur drug companies into creating new antibiotics. The Generating Antibiotic Incentives Now act, or GAIN, gives companies an additional five years of market-based exclusivity for drugs if they are produced for a “qualified infectious disease.”

“If you move to the post-antibiotic era, that means all of the advances of modern medicine could be reversed,” Cubist Pharmaceuticals’ Dr. Obi Umeh told CNBC. “Patients who had that infection in which there was no treatment option, they were in the post-antibiotic era.”
