Dallas Ebola patient had contact with children, Texas governor says

(CNN) -- Some school-age children have been in contact with the Ebola patient being treated in Dallas, Texas Gov. Rick Perry said Wednesday.
Five students at four different schools came into contact with the man, Dallas Superintendent Mike Miles added, but none has exhibited symptoms of the deadly virus. The children are being monitored at home, and the schools they attended remain open, Miles said. Between 12 and 18 people have been identified as having come in contact with the patient, who is the first to be diagnosed with Ebola in the United States, officials said.
Concern about the possible spread of the killer virus comes less than a day after the Centers for Disease Control and Prevention announced that, for the first time, a person with Ebola was diagnosed on American soil.
And the handling of the case has sparked serious questions.

The patient, a man, walked into an emergency room at Texas Health Presbyterian Hospital in Dallas on September 26. A nurse asked him about his recent travels while he was in the emergency room, and the patient said he had traveled to Africa, said Dr. Mark Lester, executive vice president of Texas Health Resources.
But that information was not "fully communicated" to the medical team, Lester said.
The man, who had flown from Liberia to the United States about a week earlier, underwent basic blood tests, but not an Ebola screening, and was sent home with antibiotics, said Dr. Edward Goodman with Texas Health Presbyterian Hospital.
Two days later, on September 28, the man returned to the facility, where it was determined that he probably had Ebola. He was then isolated. He tested positive for the virus Tuesday, health officials said.
The CDC, which has helped lead the international response to Ebola, advises that all medical facilities should ask patients with symptoms consistent with Ebola for their travel history.
It's possible that others were infected because of the lapse. People who have Ebola are contagious -- but only through contact with infected bodily fluids -- when they display active symptoms of the virus, such as a high fever, severe headache, diarrhea and vomiting, among others. It's not like a cold or the flu, which can be spread before symptoms show up, and it doesn't spread through the air.
Learn how Ebola spreads
That the man had recently arrived in the United States from Liberia should have been a huge red flag. That country is one of the hotspots in a large outbreak of Ebola in West Africa, with 3,458 cases and 1,830 deaths as of September 23, according to the World Health Organization. Other countries affected include Guinea, Nigeria and Sierra Leone. In total, more than 3,000 people have died in those countries from Ebola, and more than 6,500 have contracted the disease.
This summer, two American missionaries who were working in Liberia contracted the virus and were brought back to the United States, where they were treated with the experimental drug ZMapp. Another American doctor working with the same charity was also infected in Liberia and brought home for treatment. They all have since recovered from the virus and were released from care.
The CDC has ramped up a national effort to stem the spread of Ebola, and in September President Barack Obama spoke at CDC headquarters in Atlanta. He called the virus a global health and security threat, and pledged U.S. assistance to the affected countries to try to stem the tide of the disease.

Ebola patient in serious condition
The patient in Dallas is now under intensive care and isolated at Texas Health Presbyterian Hospital, said CDC Director Dr. Thomas Frieden.
He is in serious condition, the hospital told CNN Wednesday.
The man flew from Liberia and arrived in Dallas to visit family on September 20, Frieden explained. He started feeling ill around September 24 and sought medical care on September 26, he added.
Earlier Wednesday, CNN Chief Medical Correspondent Dr. Sanjay Gupta asked Frieden on "New Day" if the man should have been tested for Ebola on his first visit to the hospital and if he should have been asked about his recent travel history.
"That's one of the things we'll be looking at," Frieden said Wednesday morning. "But we're reiterating the message for every health worker in this country -- think about travel history. If someone's been in West Africa within 21 days and they've got a fever, immediately isolate them and get them tested for Ebola."
Gupta then asked Frieden to explain guidance the CDC has issued on that and again asked: "Should this person have been tested?"
"We weren't there so I can't tell you exactly what that person said..." Frieden responded.
Gupta interjected, "You're advising public health departments. Last time I was here (at the Centers for Disease Control and Prevention in Atlanta) there was a call with many primary care doctors to educate them on this exact issue. That was a couple of months ago. Should this person have been tested?"
Frieden answered, "We know that in busy emergency departments all over the country, people may not ask travel histories. I don't know if that was done here. But we need to make sure that it is done going forward."
Air travel testing
Every person who travels by air is screened before departure and at arrival in Liberia, Guinea and Sierra Leone, but because the man says he began feeling ill days after landing in the United States, a screening test in West Africa would likely have not turned up that he had Ebola.
However, it's unclear what kind of screening someone flying from West Africa might receive when they land in the United States, said CNN's Senior Medical Correspondent Elizabeth Cohen. She and her crew recently reported in and flew from West Africa, where she said they were screened numerous times for Ebola by having their temperatures taken at the airport.
Should we worry?
But when they arrived back in the United States, and asked travel officials about whether their temperatures would be taken or if they'd be screened for Ebola, they were given unclear explanations about how the process worked and ultimately were not tested.
Regardless, the CDC maintains that passengers on the Texas man's plane were likely not at risk because the man was not displaying active symptoms on the flight.
Frieden explained that people who have Ebola are not able to spread the disease unless they are symptomatic.
Finding the people the man came into contact with
Paramedics who transported the patient to the hospital have been isolated, Dallas Mayor Mike Rawlings' chief of staff said. They have not shown symptoms of the disease so far, Frieden said.
The ambulance used to carry the patient was still in use for two days after the transport, city of Dallas spokeswoman Sana Syed said.
But she emphasized that the paramedics decontaminated the ambulance, as they do after every transport, according to national standards.
How the virus spreads
A CDC team is in Dallas helping to find the people that the patient may have come into contact with, said Frieden.

,Once those people are identified, they will be monitored for 21 days -- taking their temperatures twice a day -- in cooperation with local and state health officials, Frieden said Wednesday.
But Gupta pointed out that the people identified as contacts aren't, as protocol, quarantined unless they are symptomatic.
"We don't want to isolate parts of the world, or people who aren't sick," Frieden said, "because that's going to drive people underground and make it harder to contain this outbreak."

What’s happening in Hong Kong?

By Evan Horowitz

  | GLOBE STAFF   SEPTEMBER 29, 2014

Protesters took to the streets of Hong Kong over the weekend, where they were met by police with pepper spray and tear gas.
What fuels the standoff is the protesters’ demand for more democracy, including the right to choose Hong Kong’s political leaders without interference from Beijing. The Chinese government, for its part, wants to keep democratic demands in check and maintain some control over Hong Kong politics.

What ignited these protests?

It’s all about 2017. That’s the year Hong Kong’s voters were supposed to gain the right to elect their own chief executive (the leader of Hong Kong). Last month, however, the Chinese government announced that all candidates would need to be pre-approved by a committee friendly to the Chinese Communist Party.
Pro-democracy groups saw this pre-approval as a way to limit the will of voters. They came together under the name of “Occupy Central” to plan protests and try to reverse Beijing’s decision.

What do the protesters want?

They want the current chief executive to resign, and they want free elections beginning in 2017.
For now, though, it’s not clear that the protesters in Hong Kong want any such change. Economically speaking, Hong Kong is a very privileged region. Per-capita income in Hong Kong is roughly as high as it is in the United States, and four times higher than in China as a whole.
Incomes in Hong Kong and China$11,904$53,203ChinaHong KongSource: World Bank, GDP per capita (PPP)
It is possible, though, that a recent economic slowdown is contributing to the unrest.

Is Hong Kong part of China, or not?

“One country, two systems.” That’s the basic framework. Hong Kong is not an independent nation but it does have a good deal of autonomy — including a separate political structure, a different legal system, and protections for free speech.
For over 150 years, Hong Kong was actually a British colony, which explains why protesters are filling streets with names like “Harcourt Road” and “Queensway.” Hong Kong gained its status as a hub of global finance while under British rule, and it didn’t rejoin China until 1997.

How has China responded to the protests?

Whether or not Chinese officials were involved in the decision to crack down on protesters, they have expressed their support for those tactics.
They’ve also been working hard to prevent the spread of information and images coming out of Hong Kong. That includes beefing up the “great firewall” and even blocking photo-sharing sites like Instagram.

How will this end?

For now, the police crackdown seems to have backfired, drawing more people into the streets and expanding the protests well beyond the bounds that even “Occupy Central” had envisioned.
To a large degree, the endgame may depend on the actions of the powerful Hong Kong business community. If businesses side with the protesters, that could put tremendous pressure on Beijing to rethink its approach. But if they choose law and order over democratic demands, protesters may be dangerously isolated.
The darkest shadow looming over these events is the one cast by the 1989 Tiananmen Square protests, where tanks were brought in and hundreds of student protesters were killed. Twenty-five years have passed since then, and a new generation of leaders has assumed power. But the legacy of Tiananmen Square remains highly chargedand the current situation may once again force Beijing to choose between accommodating demands for democracy or quashing them.

Google Chromecast HDMI Streaming Media Player

By Shauna Morgan on July 27, 2013
I actually ordered a Chromecast the day it was announced from Google. However the next day, I was told that they were available for purchase at bestbuy. I was anxious to try it out so I went and bought another one and gave it a try.

Setup was easy and within 5 minutes, I was watching a youtube video on my 65" TV. The quality was VERY good. I tried a 1080p video first "Big Buck Bunny" and it looked, played and sounded wonderful. Next, was playing music from my Google Play music app. Same result, the music sounded great.

I moved on to my Macbook Pro, and again, the videos was clear, without lag, no audio sync problems at all. Same for my Windows PC.

Those considering buying the Chromecast should consider what the Chromecast actually is and does, instead of what they wish it could do. So here are some facts:

1. The Chromecast is not a streaming device of local digital content. In other words, it does NOT play digital music and videos that is stored locally on your network drives or computers. However there is a work-around for this:

Use PLEX Media Server. If you don't already have it, here's the link:

[...]

Once you download it and point it to your files,it will act as a proxy and allow your music and videos to be played on your HDTV using the Chromecast through the Chrome browser. Simply launch the PLEX Media Manager in Google Chrome browser. Pick a file to play, Hit the Google Cast button and you'll get seamless playback of your own files. [Edit: Please see comments to see an alternative method].

2. The Chromecast is not a DLNA or Miracast device or Apple's airplay. This is a lot like my number 1 fact, but I wanted to make this clear. If you want device mirroring (display whatever is on the device's screen), the Chromecast, is NOT for you. The video and music does NOT stream from the controller device (Your computer, tablet, smartphone). Chromecast works by fetching the content from a website or cloud service itself, NOT from the device you're using. Here's what's cool about that:

A. You could start playing a video using your smartphone,tablet,computer as a "remote" and still be able to browse the web, play a game, check your social apps, write a book report, put the device to sleep,turn the device completely off (I tried this myself), or leave the house, and the video WILL still play without issues.

B. Your battery life is saved! Because your phone, tablet or computer (not plugged in)is not actually streaming to the Chromecast, your battery consumption is minimal. You could Play dozens of movies over several days and still have most of your battery life remaining (Of course this would depend on what else you do with the phone, tablet or computer and how long your device can stay in standby).

C. Every device connected to the Chromecast on the same network can take control of playback, adding to the queue (what's going to play next). Pause, fast forward, rewind, etc. So if your roommate, friend, parent, sibling, spouse, girlfriend/boyfriend has to leave with their device, you don't have to worry.

D. You can play content from thousands upon thousands of sources using your computer. Using Google Chrome, nearly every webpage, that has content can be viewed using Chromecast. Of Course, this depends what protocols the site is using. If the site has trouble playing on your computer, then it probably won't work well on the Chromecast, either.

3. Chromecast IS cross platform (works with multiple devices). As I said, I tried it with several devices with different operating systems. At the time of this review, it works on Windows PC's, Macbooks, and android devices. The app for iOS devices is coming soon. Everyone knows the Apple App store has stringent policies and at times, it can be a long process. Look at the Onlive game streaming app. We won't get into how Apple has been trying to eradicate google applications from it's ecosystem anyway. I'm sure the app is waiting for approval. Just be patient. [Edit: Please see comments for a reply to it working on iOS devices].

There are several youtube videos that can show you how to set it up or how well it works. I made a video myself:

[...]

Watching my video isn't required, but it does help to verify what I'm saying.

4. The device you use with the Chromecast, must be on the same WIFI network. The important word here is WIFI. If you are trying to use it, with a ethernet (wired) connected device, even though it's on the same network, it will NOT work! Yes, that sucks, but not being able to use sink water in your gas tank, kind of sucks to. If that's a deal breaker for you, then you shouldn't purchase it. It's how they chose to implement it's use. It is, what it is. [Edit: Please see comment section].

5. The Netflix 3 months free limited time offer is over! I received 3 months free with both my purchases. I live in the eastern time zone. Even though I bought my second Chromecast on July 25th at 6:46pm. I realize that when the offer was no longer available, it should have been posted immediately so that consumers could factor that into their decision to buy the Chromecast. Instead of calling it a limited time offer, they should have said "while supplies last." Never the less, the features and functionality of this device has nothing to do with the inadequacy of a bonus offer. To help people make a decision about a future purchase and if it will work for THEM in the home configuration they have, is paramount in my book.

6. The Chromecast REQUIRES power through USB connection or from your wall outlet. The required peripherals ARE provided to you in the retail box. Some people are saying if you have an HDMI 1.4 compatible port on the back of your TV, the device can be powered by the HDMI port alone, without the USB cord connected. I CANNOT speak to that, as my HDMI ports did NOT power the Chromecast. I had to use the provided USB wire and connect it to a USB port available on the back of my TV.

Overall, I'm extremely pleased with the purchase. I've read some of the other reviews, particularly the 1 and 2 star reviews, because it's an indicator of what can possibly go wrong with the device. I would suggest that people make their decision based on people that have actually bought the device and have experience connecting, setting it up and ACTUALLY using the device. Most of the bad reviews are from people that have not used it, didn't understand the features of the device, or, to be honest, has a problem with the competition between Apple and Google and wants to dismiss this product because of their affinity for Apple products. Look at the features and functions of this device and consider them for yourself.

I hope this review helps someone who may be considering this device.

EDIT: Recently more apps were added with chromecast support, including the PLEX app! Other editions are: HBO Go, Hulu Plus, Pandora, Vevo, Redbull.tv, Songza, Post TV, Viki, Real Player Cloud.
