Salmonella poisoning symptoms and warning signs

  Salmonella poisoning symptoms and warning signs Eating food that’s contaminated with salmonella bacteria may cause you to be ill and experience discomfort for several days. You’re feeling sick several hours after a tasty meal — is it just a “food coma,” or a case of salmonella poisoning?If it’s the latter, you may feel ill and experienc The infection is rarely fatal. The problem may stem from your own dinner table: consuming raw and undercooked animal products that are contaminated can cause infection, the Food and Drug Administration (FDA) says. Contaminated raw produce is another possibility, according to the agency.

How does flu spread ? A team at the University of Maryland is studying how one person passes influenza virus to another. It’s all part of an experiment to find out just how flu spreads .

Do an Experiment . We answered this question on the show Chris - Okay, Les. Very good question and very topical too because we’re expecting flu to arrive in the UK at any moment. Actually, how it spreads though is again down to either birds or humans.

This is not a beauty session. Thomas is also giving blood samples and her nose and throat will be swabbed.

It's all part of an experiment to find out just how flu spreads. Thomas and Weisman are students at the University of Maryland, where Dr. Donald Milton and colleagues are taking a deep dive into influenza in one of its richest habitats — a college dormitory.

Thomas has been in close contact with a flu patient, and now Milton's team will watch her and test her to see if and when she comes down with flu herself.

"Who is going to become contagious?" Milton asked.

Man claims he contracted eye-eating parasite from amusement park water ride

  Man claims he contracted eye-eating parasite from amusement park water ride A Pennsylvania man and his wife have filed a lawsuit against an amusement park over claims that he contracted an eye-eating parasite after going on one of the water rides. Robert Trostle, who claims he was splashed while riding on Kennywood Park’s Raging Rapids on July 2, said the parasite could not be removed entirely through surgery, and has left him with painful symptoms, The Pittsburgh Post-Gazette reported.Trostle and his wife, Krystsina, claim they noticed that the ride’s water supply was “dirty, stagnant and sludge-like,” while waiting in line.

The tests will help identify the route of transmission — whether people get infected by large droplets of mucus or saliva that carry flu virus into their nasal passages, whether they pick up the virus on their fingers from droplets that have fallen onto surfaces such as desks, or whether they breathe in the virus on tiny, airborne particles.

It's an especially timely experiment. The U.S. is suffering through one of the most severe flu seasons in recent years. Almost every state is experiencing widespread flu activity at the same time — an unusual pattern. Understanding how and when influenza spreads can help doctors understand and, perhaps, better control the annual flu epidemic.

Signs around the campus urge students to come in if they start feeling ill to be tested for flu. If they are positive, they're asked to give up the names of four close contacts so they can be tested for flu and followed.

Students are also asked to download an app, also designed by a student there that tracks their movements. The cellphone app can show whether they were exposed to roommates or someone in a study room.

College residence halls are perfect breeding ground for respiratory viruses such as flu.

"You're sharing the same air in small rooms," said Dr. Barbara Albert, head clinician helping oversee the study. "They may not even know they've been in contact with somebody else."

Although influenza causes an epidemic every single year, and some years causes a more serious pandemic, how it is transmitted is poorly understood. Scientists estimate that each flu patient infects about one-and-a-half other people on average, a number known as R0 (r zero).

Tokyo airport to be 'scattered' with robots for 2020 Olympics

  Tokyo airport to be 'scattered' with robots for 2020 Olympics Visitors to the 2020 Tokyo Olympics can expect to arrive at an airport "scattered" with robots to help them, an official said Tuesday as he unveiled seven new machines to perform tasks from helping with luggage to language assistance. Among the seven robots on show was a fluffy cat mascot that can carry out simultaneous interpretation in four different languages. Visitors speak into a furry microphone, and translations appear instantly on a smart screen.Travellers may also be approached by a small white humanoid robot, Cinnamon, asking if they need its help.The sleek white robot can converse with visitors through its AI system and give directions.

It's known that people can transmit influenza before they feel sick, and after they feel better, and that the virus spreads on droplets. But more subtle factors may aid the spread of flu.

Facing the sneeze machine

Milton's lab showed earlier this year that flu virus can remain suspended in the air in tiny particles that people emit when they are breathing normally — something that many doctors had believed did not happen.

"We are all breathing out potentially infectious viruses," said Stefanos Koutsoukos, a biochemistry major who is one of 68 students earning college credit while helping with the experiment. "It's led me to think differently about how I may have become sick."

They use Milton's Gesundheit 2 machine to measure this, recruiting patients with flu to sit with their faces in the cone-shaped collection device to see what they send out with each breath.

"We are trying to figure out what students are getting sick with," said Christine Shi, a public health major who is working on the experiment. "How much virus do the students emit?"

Researchers are worried that a brain illness known as 'zombie deer' disease may start infecting humans

  Researchers are worried that a brain illness known as 'zombie deer' disease may start infecting humans <p>Canadian researchers are concerned the disease could potentially start to infect humans who eat deer, elk, moose, or other members of the animal family that carry misfolded proteins.</p>At some point, the animal will start to lose weight, stop interacting with other deer, lose its fear of humans, and may start drinking and salivating more. Ultimately, it winds up staring vacantly as it starves to death. That's why the illness is also known as "zombie deer" disease.

No one wants to get a flu , and because it makes you feel so bad, two of the most common questions a person asks are: “ how long does the flu last?” and “what treatment can I get to feel better?”. In this article I am going to answer these questions as well as describe the differences between cold and flu .

If someone develops flu after a close contact has had it, the tests can show how they became infected. Genetic tests can establish if student A infected student B directly.

"We can deep sequence the flu virus and see the source," Milton said. The samples are sent to the University of Maryland's Institute for Genome Sciences for those tests.

Which particles are worse?

A patient's symptoms may be a function of how they caught the virus. Milton has a theory that flu causes worse symptoms if inhaled on tiny, airborne particles rather than from larger particles that are coughed or sneezed out and either breathed in or picked up from a surface.

The smaller particles, he believes, can be sucked directly down into the lungs and lower airways, making people sicker. Students' cellphones are also being swabbed.

"I think infection route matters," Milton said.

They ask about stress, physical activity and sleep. "We are trying to get a broad picture of susceptibility," Milton said.

The team has a grant from the Defense Advanced Research Projects Agency (DARPA) to develop various tests for infection.

"They want to know if we can identify a signal in the blood to tell us who is going to infect everybody else," Milton said.

Last year, a few students showed up with flu but more had other viruses that cause similar symptoms, such as coronaviruses and respiratory syncytial virus or RSV. Out of 72 students tested last year, 13 had RSV-B, 10 had coronavirus OC43, 10 had adenovirus, eight had influenza A, and the rest had an assortment of coronaviruses, RSV strains, rhinovirus and another flu-like virus called human parainfluenza virus.
