Swine Flu May Infect Internet Too ( Part 2 )

Such a reduction would require adjusting the configuration file within each customer's modem to temporarily reduce the maximum transmission speed that that modem was capable of performing—for example, by reducing its incoming capability from 7 Mbps to 1 Mbps.

However, according to providers the GAO spoke with for its report, such reductions could violate the agreed-upon customer service levels for which customers have paid. In the end the GAO said that technically feasible options would likely require a government directive.

Some of the GAO's other conclusions included:

•Voluntary actions taken by the general public could have significant potential to reduce the surges in traffic loads that residential users may experience during a pandemic. For example, the general public could be asked to limit video streaming, gaming, and peer-to-peer and other bandwidth-intensive applications during daytime work hours.

•Shutting down specific Internet sites would also reduce congestion, although the GAO said many industry players expressed concerns about the feasibility of such an approach. Overall Internet congestion could be reduced if Web sites that accounted for significant amounts of traffic—such as those with video streaming—were shut down during a pandemic.

•Providers could help reduce the potential for a pandemic to cause Internet congestion by ongoing expansions of their networks' capacities. Some providers are upgrading their networks by moving to higher capacity modems or fiber-to-the-home systems. For example, some cable providers are introducing a network specification that will increase the down load capacity of residential networks from the 38 Mbps to about 152 to 155 Mbps.

•Until DHS develops an effective response strategy, coordinates with federal and other partners on actions to take, determines whether sufficient authorities to act exist or are sought, and evaluates the need for a public campaign, employees in critical sectors of the nation's economy, including those in financial services, might not be able to effectively telework or otherwise communicate or transmit data over the Internet during a pandemic.

Swine Flu May Infect Internet Too ( Part 1 )

Government watchdogs are warning that the H1N1 pandemic will led to increased Internet usage. This could create serious network access congestion, says Network

World While sounding a bit like Chicken Little, Federal government watchdogs today said that the H1N1 pandemic will cause a significant increase in the use of the Internet by students and teleworkers that would create serious network access congestion. Such problems may need to be fixed by government involvement or service providers limiting network access or by asking people to lay off the streaming videos for a while.

Congestion affecting home users is likely to occur because the parts of providers' DSL, cable, satellite, and other types of networks that provide Internet access from residential neighborhoods are not designed to carry all the potential traffic that users could generate in a particular neighborhood or that all connect to a particular aggregating device, a Government Accountability Office report looking at the impact of a pandemic on the Internet stated.

Internet congestion will be exacerbated by localities which may choose to close schools and these students, confined at home, will likely look to the Internet for entertainment, including downloading or streaming videos, playing online games, and engaging in potential activities that may consume large amounts of network capacity, the GAO stated.

Although predicting that the most severe congestion would occur within residential access networks, a study overseen by the Department of Homeland Security also noted that pandemic-related congestion was possible in other parts of the networks that comprise the Internet, the GAO stated. DHS is responsible for ensuring that critical telecommunications infrastructure stays up and running during periods of national duress.

For example, users could experience congestion at peering points where traffic is transferred between service providers because of potential differences in transmission capacity. Additionally, teleworkers connecting to their enterprise networks could overload various components of these networks, such as firewalls or servers that provide access to various applications because some businesses' networks may not have scaled these devices to accommodate the anticipated increase in telecommuting traffic during a pandemic, the GAO stated.

Can service providers ease the pain? Maybe. Providers' options for addressing expected pandemic-related Internet congestion include providing extra capacity, using network management controls, installing direct lines to organizations, temporarily reducing the maximum transmission rate, and shutting down some Internet sites. Each of these methods is limited either by technical difficulties or questions of authority, the GAO stated.

Providers said they would focus on ensuring services for the federal government priority communication programs and performing network management techniques to re-route traffic around congested areas in regional networks or the national backbone. However, these activities would likely not relieve congestion in the residential Internet access networks, the GAO stated.

In the current network environment, providers' capability to address pandemic-related Internet congestion by prioritizing certain users' traffic, including that of financial sector teleworkers, is limited. Although providers cannot identify users at the computer level to manage traffic from that point, two providers told the GAO that if the residential Internet access network in a particular neighborhood was experiencing congestion, a provider could attempt to reduce congestion by reducing the amount of traffic that each user could send to and receive from his or her network.

Swine flu: Answers to your H1N1 questions

As more and more people are getting infected by the dreaded swine flu, questions linger about the dangers of the virus and the effectiveness of inoculations. Here are edited queries from Tribune readers, with answers:

Q: What is the comparison between the fatality rates for H1N1 flu and seasonal flu, and is H1N1 considered more of a danger than seasonal flu?

A: Since the pandemic began in April, more than 1,000 deaths from H1N1 have occurred, including about 100 children, and more than 20,000 hospitalizations in the United States, according to the U.S. Centers for Disease Control and Prevention. The CDC estimates that about 36,000 people die of seasonal flu-related causes annually, although the number fluctuates.

It is good news, according to Kathleen Sebelius, secretary of the U.S. Department of Health and Human Services, that the swine flu continues to be "very mild" for most people. "But there is no question we are seeing very severe cases hit in populations normally not susceptible to the flu, and without underlying health conditions in some cases," she said this week. "Young people and pregnant women have been particular targets of that."

Q: Is it true that people who get the H1N1 mist are getting a live virus which they can shed, infecting people with depressed immune systems?

A: The nasal spray is made from live, weakened virus. There is a bit of "shedding" -- where some of the vaccine escapes. But the amount is so small, there is no need to worry about spreading it in the general population, according to Dr. Julie Morita, medical director of the Chicago Department of Public Health's immunization program.

The only concern, she said, is among health care professionals who care for people whose immune system is compromised. "A doctor in a regular setting can get the nasal spray and not worry about shedding, but those taking care of people with a weakened system should not get the vaccine or go to work immediately after taking it," she said.

Clinical studies show the risk of getting infected after contact with attenuated, or weakened, vaccine virus is minuscule -- between 0.6 and 2.4 percent.

Q: My children, ages 2 and 5, got the first round of H1N1 shots, but the doctor said she wasn't sure she will have the second dose a month later. Are they protected with just one shot?

A: Health officials recommend that children under the age of 10 receive two doses of vaccine, separated by four weeks. Health officials said every attempt should be made to obtain the second dose in order to achieve full protection. More vaccine is on its way so people should check regularly with their doctor, school and local health departments.

Q: Our mom is really sick and we aren't sure if it's swine flu. If we wear masks and sort of keep a distance from her, will we be OK?

A: A bit more than that is needed to avoid the virus, according to the CDC. If possible, your mom should be in a private room away from common areas of the house and use a separate bathroom. If she has to be around others, she should wear a mask. Everyone should wash hands regularly. If you are under 24, you might consider getting an H1N1 vaccine.

Q: I am pregnant with triplets, due to give birth in 10 days. I brought my 2-year-old son, my husband and my mom (our caretaker) to Truman College's clinic on Saturday. We waited in line for 5 1/2 hours for the vaccine. ... What kind of screening are they doing for these shots, just first come, first served?

A: With a limited supply of vaccine at each clinic, Chicago Health Department officials are trying to limit it to high-priority groups. But mostly they are relying on people being honest when asked in line if they fall into one of those groups.

"We're trusting people to do the right thing," said Julie Morita, director of the department's immunization program.

According to Tim Hadac, a department spokesman, officials are confident that nearly everyone who got vaccines at the first clinics was in a high risk group, although a "small percentage" might have slipped through. Some people had asthma, diabetes, immune disorders and other chronic illnesses that would not always be obvious to other people in line, he said.

Overall, those eligible for early vaccines are health care workers; pregnant women; children and young adults ages 6 months to 24 years; people who live with or care for infants younger than 6 months; and people ages 25 to 64 with chronic health conditions. The public clinics are being offered Tuesdays, Thursdays and Saturdays at six City Colleges campuses as long as there is demand and supply.

Q: We are going to visit my in-laws for Thanksgiving and we were told we can't see my father-in-law unless we have H1N1 shots. I have chronic sinusitis plus a diminished immune system, so how likely am I to find the vaccine before Thanksgiving? Is there a list of locations that have the vaccine?

A: You should call your doctor or health care provider to see if it is available, and where. Once the vaccine is readily available, a list of health departments and pharmacies will be made available on the Illinois Department of Public Health Web site, www.idph.state.il.us.

The vaccine continues to be in short supply across the country because of production delays. Health officials have said they expect a better supply by mid-November and that by early December, the vaccine should be widely available. Most vaccine is now going to local health departments and hospitals.

Q: The city of Chicago has the vaccine. DuPage County has it. Cook County Department of Health -- nada. Why is Cook County so behind?

A: Cook County Health Department officials said they got their initial 20,000 doses of vaccine late last week. Six thousand doses were allocated to hospitals in suburban Cook County and about 5,000 doses to public schools in Palatine, the first district designated for student vaccinations. Other doses have been reserved for health care workers at the county Health Department. No vaccine is currently available for public clinics, a county spokesman said. Officials were "cautiously optimistic" the department will get more vaccine early next week that will allow for public clinics to begin soon in suburban Cook County.

Q: Are there precautions a family should take regarding trick-or-treat candy this Halloween?

A: State and local health officials recommend giving out wrapped candy. Rather than allowing children to reach into a bowl, hand it to them. Children should wash their hands, use sanitizer and wash any fruit or other food.

FDA warns: Swine flu scams lurk on the Internet

People be warned. Many people feared this pandemic and are desperate themselves to seek a vaccine which could protect them against this dreaded disease. But some are capitalizing on this tragic event by claiming they have the means to battle this global pandemic.

Air "sterilizers." A photon machine. Supplement pills to boost the immune system. Protective shampoos and face masks. Even fake Tamiflu.

These and other products making bogus claims to prevent or treat swine flu are flooding the Internet as scam artists prey on the public's fears while the vaccine is delayed and real Tamiflu — made by Switzerland's Roche Group — is rationed.

Every problem, it would seem, is a sales opportunity. Some of the products appear to have been pitched for other emergencies, such as one called "Quake Kare" and masks and purifiers sold during the SARS scare.

Federal officials have sent warning letters to promoters of more than 140 swine flu-related products, including well-known alternative medicine advocate Dr. Andrew Weil for his "Immune Support Formula."

Consumer Reports also has warned subscribers to be wary.

"It's harmful, disappointing, frustrating to see folks take advantage of the public like this," said Dr. John Santa, who evaluates health claims for Consumer Reports.

Fraudulent products emerged shortly after swine flu did last spring — about 10 a day, said Alyson Saben, head of a swine flu consumer fraud team formed by the Food and Drug Administration. The pace slowed over the summer as the flu abated, but "it's picked up" in recent weeks, she said. "We are seeing new sites pop up."

Most worrisome: sites that claim to sell Tamiflu without a prescription. The FDA bought and tested five such products. One contained powdered talc and generic Tylenol — no Tamiflu. Several others contained some Tamiflu but were not approved for sale in the U.S.

"We have no idea of the conditions under which they were manufactured. They could contain contaminated, counterfeit, impure or subpotent or superpotent ingredients," Saben said.

Tamiflu and GlaxoSmithKline's Relenza are the only drugs recommended for treating swine flu.

Rogue Web sites are not the only ones trying to cash in on flu fears. Makers of some well-established products are making claims that may be close to the line, the FDA says.

This week, the makers of Dial Soap, Kleenex, Clorox and other big brands launched a joint promotional campaign costing up to $1 million. The FDA is reviewing the campaign, which includes a video that says:

"Germs are tiny organisms that can cause disease. According to the CDC, up to 80 percent of infectious diseases, like the flu, are spread by your hands. That's why frequent, proper handwashing is so important in preventing spread of the flu, other viruses and germs. An antibacterial soap like Dial Complete foaming hand wash kills 99.9 percent of germs."

Flu is caused by a virus, so killing bacteria is of uncertain benefit.

The campaign is "not being specific down to swine flu," said Scott Moffitt, an official with Dial Corp.'s parent company, Germany-based Henkel AG. He also contends the video is not misleading, even though the germ-killing claim follows a sentence about flu and other viruses.

One product that drew a warning letter from the FDA is the Photon Genie, a gadget that delivers "energy waves." Its Web site claimed it "helps strengthen the immune system, and a strong immune system is KEY to preventing swine flu symptoms and KEY to treating swine flu."

The site has since removed the swine flu claim but "other claims remain," Saben said.

The group behind the Web site, the Skilling Institute of Phoenix, "is not marketing, and will not market in the future, any product that is intended to diagnose, mitigate, prevent, treat or cure the H1N1 flu virus," its director, Warren Starnes, wrote in an e-mail.

Some products the FDA warned about contain silver, such as "Swine Flu...Gone," made by Secrets of Eden.

"Spray 'Swine Flu...Gone' with ionic silver on your hands and on any surface where these germs may exist and kill the virus," its site had claimed.

Secrets of Eden sells supplements and oils with a biblical flair, said its general manager, Rick Strawcutter, a former pastor in Adrian, Mich. The staff "got a little carried away" on marketing for one product and "drew the ire of the FDA," he said.

"It was not worth contesting," so he ordered a stop to it, Strawcutter said.

The federal Agency for Toxic Substances and Disease Registry says silver "may cause harmful health effects," depending on the amount and type of exposure.

Dr. Andrew Weil's site had this problem language, the FDA's warning letter said: "...during the flu season, I suggest taking a daily antioxidant, multivitamin-mineral supplement, as well as astragalus, a well-known immune-boosting herb that can help ward off colds and flu. You might also consider ... the Weil Immune Support Formula which contains both astragalus and immune-supportive polypore mushrooms."

Weil issued a statement saying the content "was primarily educational" about how to avoid the flu, and that he had directed his Web site team to remove and review it for compliance with federal rules.

Doctors, too, are being warned not to prescribe unproven remedies, such as drugs not shown to be safe and effective for swine flu. In this week's New England Journal of Medicine, three FDA doctors caution against use of ribavirin, a drug approved in the U.S. for treating hepatitis C and respiratory syncytial virus, or RSV, a childhood illness.

There have been reports of doctors wanting to try it for seriously ill flu patients, but it can cause a dangerous type of anemia and cannot be used in pregnant women because of the risk of birth defects, said the FDA's Dr. Debra Birnkrant.

"It shouldn't be used lightly" and needs to be tested in a clinical trial for flu, she said.
