ZIKA

Symptomless man linked to sexual transmission of Zika for first time

The U.S. Food and Drug Administration called Friday for all blood donations in the U.S. to be screened for Zika virus. The move deviates from the medical agency’s guidance released in February, which recommended screening only for areas with active transmission of the virus via the mosquito population. The new advisory applies to whole blood and blood components used in the U.S. and its territories.

“There is still much uncertainty regarding the nature and extent of Zika virus transmission,” Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research, said in a statement. “At this time, the recommendation for testing the entire blood supply will help ensure that safe blood is available for all individuals who might need transfusion.”

The guidelines come as instances of non-travel-related infections appear outside of Miami. On Monday, Florida Gov. Rick Scott announced a locally transmitted case in Pinellas County near Tampa Bay, while Palm Beach County reported its second local infection on Wednesday. Further south, Miami-Dade County has experienced 39 local infections, while Broward noted one. Overall, the state has recorded 577 cases of the disease.

Elsewhere, a Maryland man without symptoms appears to have spread the virus to his partner via intercourse, according to a new report from the Centers for Disease Control and Prevention. The man in question traveled to the Dominican Republic, returned and had condomless sex with his partner, and she developed a Zika infection with symptoms 10 days later.

This is potentially the first reported case of a symptomless individual spreading the virus sexually. (France reported a possible incident in April, but in that case, both partners had recently traveled to a country with active Zika transmission.)

The CDC is careful to state that this single case doesn’t mean every asymptomatic person returning from a Zika-hit nation carries a risk of sexually transmitting the virus. But the case report raises new concerns about the reach of the virus.

SEXUALLY TRANSMITTED INFECTIONS
ANTIBIOTIC RESISTANCE

http://www.thefrisky.com/2016-09-02/...e-untreatable/

Quote:
The infections causing extra worry these days are gonorrhea, chlamydia, and syphilis. The World Health Organization (WHO) issued a warning statement Tuesday that some antibiotics are now failing due to overuse and misuse, though gonorrhea has developed the strongest resistance to antibiotics of the three bacterial infections. “Because of widespread resistance, older and cheaper antibiotics have lost their effectiveness in treatment of the infection,” WHO said. The organization recommended new guidelines for treating the STIs, no longer suggesting doctors prescribe an entire class of antibiotics — quinolones — because strains of gonorrhea resistant to it have formed across the globe.

The news release said 78 million people are infected with gonorrhea each year, 131 million with chlamydia, and 5.6 million with syphilis. “Chlamydia, gonorrhoea and syphilis are major public health problems worldwide, affecting millions of peoples’ quality of life, causing serious illness and sometimes death,” said Ian Askew, WHO’s director of reproductive health and research, in the statement posted online. He continued to say, “National health services need to monitor the patterns of antibiotic resistance in these infections within their countries.”

ZIKA

does it really cause microencephaly?

https://www.sciencedaily.com/release...HsdEs.facebook

Quote:
Recently, the New England Journal of Medicine published the preliminary results of a large study of pregnant Colombian women infected with Zika. Of the nearly 12,000 pregnant women with clinical symptoms of Zika infections until March 28, no cases of microcephaly were reported as of May 2. At the same time, four cases of Zika and microcephaly were reported for women who were symptomless for Zika infections and therefore not included in the study itself.

Is it possible that more time is needed for births to give rise to the high numbers seen in Brazil? The numbers don't add up according to the NECSI report. The Zika and microcephaly cases that are not part of the study show that there are many more pregnancies affected by Zika without symptoms. Because there are four cases of microcephaly with Zika, and none in the study, there should be about four times as many cases of Zika that are unreported. This means there are at least 60,000 Zika-infected pregnancies in Colombia.

The NECSI report analyzes the data and shows that the four cases of Zika and microcephaly that have been observed till April 28 are just what would be expected due to the background rate -- of the 60,000 pregnancies about 20,000 births would already be expected. The expected microcephaly rate for countries with no reported infections of 2-in-10,000 births gives exactly four cases. The study also notes that until April 28 there has been a total of about 50 microcephaly cases in Colombia, of which only four have been connected with Zika. The four cases are expected for the coincidence of Zika and microcephaly in the same pregnancies even if Zika is not the cause.

In light of this evidence, NECSI says the cause of microcephaly in Brazil should be reconsidered. One possibility that has been raised is the pesticide pyriproxyfen, which is applied to drinking water in some parts of Brazil to kill the larvae of the mosquitos that transmit Zika. Pyriproxyfen is an analogue for insect juvenile hormone which is cross reactive with retinoic acid, which is known to cause microcephaly. A physicians group in Brazil and Argentina, the Swedish Toxicology Sciences Research Center, and NECSI have called for further studies of the potential link between pyriproxyfen and microcephaly.

FLORIDA
HAND FOOT AND MOUTH DISEASE

Hand, foot and mouth disease hits FSU

A viral infection more common to babies and toddlers has hit Florida State University student living quarters, prompting university officials to cancel several events Tuesday night including fraternity rush activities.

An outbreak of hand, foot and mouth disease has struck a small group of students, officials said.

“We are aware of more than a dozen cases so far,” said Lesley Sacher, director of the FSU Health and Wellness Center in a university release.

There is no treatment for the virus, which can cause mouth sores, skin rash and fever, according to the Centers for Disease Control. It takes about five days for the infection to run its course, university officials said.

FSU crews are wiping down affected dormitories with bleach and enacting "sanitation protocols for all public spaces on campus," officials said. All living areas — dorms, fraternity and sorority houses, and others — have been advised to disinfect and provide bottles of hand sanitizers if they don't already have them.

Scientists discover 3 new strains of norovirus that are causing gastro outbreaks
Three is definitely not better than one.

Australian scientists have discovered three new strains of norovirus, which they say are responsible for a local outbreak of viral gastroenteritis over the last couple of months.

At the worst point of this outbreak, cases of gastro outnumbered influenza during peak flu season in some areas of Australia.

cases, a temporary loss of taste.

The virus is spread through things like aerosol particles and infected faeces, and can stay on surfaces for at least seven days. As few as five virus particles are all that’s needed to infect someone with norovirus.

Worldwide, the virus affects 267 million people, and causes 200,000 deaths per year, usually in patients with weakened immune systems, such as infants or the elderly.

In 2012, researchers from the University of New South Wales (UNSW) in Australia had found a strain of norovirus they named Sydney 2012, which was causing a worldwide pandemic of gastro.

"Norovirus is highly infectious and can spread through aerosol particles when people vomit," said lead researcher, Peter White.

"During the past 20 years there have been six global epidemics of norovirus, in 1996, 2002, 2004, 2006, 2009 and 2012."

SEPSIS

http://www.nytimes.com/2016/09/20/we...tionfront&_r=0

Quote:
Sepsis appears to be rising. The rate of hospitalizations that listed sepsis as the primary illness more than doubled between 2000 and 2008, according to a 2011 C.D.C. study, which attributed the increase to factors like the aging of the population, a rise in antibiotic resistance and, to some extent, better diagnosis.

Sepsis is a contributing factor in up to half of all hospital deaths, but it’s often not listed as the cause of death because it often develops as a complication of another serious underlying disease like cancer. So although death certificates list sepsis as a cause in 146,000 to 159,000 deaths a year, a recent report estimated that it could play a role in as many as 381,000.

Yet advocacy organizations say many Americans have never heard of sepsis and don’t know the signs and symptoms.

.....
Now the C.D.C. is starting a major public awareness campaign to make sepsis a household word. The first step is to teach people to seek treatment quickly when a loved one begins to show symptoms of sepsis, which include chills or fever; extreme pain or discomfort; clammy or sweaty skin; confusion or disorientation; shortness of breath; and a high heart rate.

......
“We want people to be able to recognize sepsis just like they recognize a heart attack or stroke, and know they shouldn’t wait until Thursday when the doctor can see them, but go to the emergency room right away,” said Thomas Heymann, executive director of Sepsis Alliance. The group’s motto is, “Suspect sepsis, save lives.”

.....
The new C.D.C. study found sepsis is most often associated with lung, urinary tract, skin and gut or intestinal infections, and that many sepsis patients had visited a doctor or been in a health care setting before developing the infection.

"Endemic transmission of measles has been eliminated from the region," said World Health Organization director Margaret Chan.
.....
The end of endemic transmission means the virus is no longer commonly spread locally, although imported cases may still lead to isolated outbreaks.
And besides, this thread is worldwide, not just the Americas.
