Pandora Report 11.16.14

Its getting pretty cold outside, right? So what better way to spend your Sunday than catching up on all the best stories of the week! This week we’ve got Wikipedia as a predictive took for the spread of disease, a catchy new name for Chikungunya, MERS CoV in Saudi Arabia, some stories you may have missed, and, of course, an Ebola update.

How Wikipedia Reading Habits Can Successfully Predict the Spread of Disease

In my absolute favorite story of the week, researchers have identified a link between the spread of disease and the corresponding page hits of those diseases on Wikipedia. No, the Internet isn’t giving people E-bola, but page views seem to have a predictive effect on infectious disease spread. During the three-year study, looking at readers’ habits, the researchers could predict the spread of flu in the U.S., Poland, Thailand, and Japan, and dengue in Brazil and Thailand at least 28 days before those countries’ health ministries.

The Washington Post—“Official government data—usually released with a one- or two-week lag time—lagged four weeks behind Wikipedia reading habits, according to Del Valle; people, she said, are probably reading about the illnesses they have before heading to the doctor.”

The ‘Vacation Virus’

As Chikungunya makes it way through the Americas, awareness of the disease becomes more important—including the creation of a catchy nickname! The vector, transmissibility, and symptoms are similar to Dengue and with Chikungunya being relatively new to the western hemisphere, a story like this one may be helpful in putting a human face on a growing problem.

The Atlantic—“It might be parochial to call Chikungunya a “vacation virus”; however, as Americans prepare to hit the Caribbean beaches in the coming winter months, awareness campaigns are ramping up. Last week, the travel section of the New York Times ran a feature on Chikungunya highlighting how tourism agencies and organizations are both downplaying the scope of the outbreak and advising simple measures to deal with the virus.

MERS Cases on the Rise in Saudi Arabia

Since September 5, there have been 38 new cases of MERS-CoV in Saudi Arabia, bringing the total number of cases in Saudi Arabia to 798. The WHO said that due to the non-specific symptoms of MERS, it is critical that health care facilities consistently apply standard precautions with all patients regardless of their initial diagnosis. Furthermore, until more is understood about MERS, immunocompromised individuals should practice general hygiene measures, like hand washing, and avoid close contact with sick animals. Nearly one third of the new cases were reported by patients who had recently had close contact with camels.

Outbreak News Today—“The continued increase in cases prompted Anees Sindi, deputy commander of the Command and Control Center (CCC) to say, “MERS-CoV is active and we need to be on full alert.” In addition, the Saudi Arabia Ministry of Health launched a new public information campaign in Taif in response to the recent spike in new cases of MERS-CoV in the region. Medical professionals will be made available at public locations with the aim of educating citizens on the need to avoid unprotected contact with camels because of the risk of infection with MERS-CoV, underlining the crucial role of the community in preventing the spread of the disease in the Kingdom.”

This Week in Ebola

Ebola is on the rise again in Sierra Leone bringing the number of deaths to 5,147 and cases to 14,068. It appears that the virus is finding new pockets to inhabit including villages outside the Liberian capital and in Bamako, the capital of Mali (eclipsing earlier success in that country at containment.) Despite these new infections outside of Monrovia, Liberian President Ellen Johnson Sirleaf has ended the state of emergency in that country. Unsurprisingly, the epidemic has imposed a financial burden on the affected countries including losses in agricultural trade and the service industries. Elsewhere in Africa, Ugandan health officials have declared the country free of an Ebola-like Marburg virus. Stateside, a new report from the CDC outlines steps taken in Dallas to prevent further virus spread and a third Ebola patient headed to the bio containment unit at the Nebraska Medical Center for treatment. Finally, 80 U.S. Military personnel helping to fight Ebola in Liberia returned home this week, and though none are displaying symptoms, they will be monitored for 21 days at Joint Base Langley-Eustis in Virginia.

Image of the Week: Influenza

For those of you wondering what influenza’s mechanism of infection looks like, please see the below! Hemagglutinin is the H portion, and neuraminidase is the N – H1N1 therefore refers to the H1 hemagglutinin and the N1 neuraminidase. Both are surface glycoproteins responsible for host cell binding.

Spike in H7N9 Cases Elicit new warnings

From Shanghai Daily – “At least 31 people died from H7N9 bird flu in China this year, the government announced yesterday, while health experts predicted more H7N9 cases in the near future. A total of 127 human H7N9 cases have been confirmed so far this year, with Zhejiang and Guangdong provinces the worst affected, according to a statement by the National Health and Family Planning Commission. The number is almost as high as for the whole of last year, when China had 144 confirmed cases, including 46 deaths. The commission said that there will continue to be sporadic reports of H7N9 infections. Flu viruses are seasonal and the first human cases emerged in February 2013, so that the outbreak did not encompass all of last winter. It has reignited fears that a bird flu virus could mutate to become easily transmissible between people, threatening a pandemic.”

Three New Cases of MERS, 1 Fatality

 

A 73-year-old Saudi man is the most recent MERS fatality, bringing the total in Saudi Arabia up to 56. To date, there have been 136 cases of the virus globally. Saudi Arabia also reported three new cases of the virus, including two foreign health workers, and a 53-year-old Saudi man.

Deadly Pig Virus from China

According to a new study research, porcine epidemic diarrhea virus (PEDV) striking piglets across farms in the US may have originated in China. After comparing strains from an outbreak in China and the recent US strains, research from Virginia Tech indicates the virus’ source is in the Anhui province.

Fox News – “The report should help diagnostic researchers and federal officials, who have been trying to trace the origin of the porcine epidemic diarrhea virus (PEDv) since it was first identified in the United States this past spring. Previously, investigators and veterinary researchers tracking the outbreak said that there was some indication that the PEDv strain seen in the U.S. was 99.5 percent similar in genetic make-up to that identified in China. But exactly where it came from and how it arrived in the United States were mysteries. According to the report published last week in the American Academy of Microbiology journal mBio, the researchers extracted strains of PEDv virus from infected animals in Minnesota and Iowa.”

Image of the Week: Bacterial Growth!

This week’s image is brought to us via the Nikon Small World Photomicrography Competition. It wasn’t first place, but we thought it was a vivid depiction of bacterial life. Taken by Neil James Egan of PPG Industries, the image depicts two distinctive nodes during bacterial separation. Head over to Nikon’s website to see many more entries!
