Avian influenza, bird flu, H5N1
A bird flu pandemic has killed thousands of wild birds over the last couple of years. Scientists have now seen infection in mammals, and very recently a person died from avian influenza and several close contacts show signs of  infection. The concern is that we might be headed for another H5N1 pandemic. Previous strains of H5N1 that infected people had a mortality rate of 60 percent. Avian influenza, bird flu, H5N1 There are fifteen known variants of avian influenza. The most virulent, and usually fatal in birds, are the H5 and H7 strains. There are then nine variants of the H5 strain and the type of most concern because ...

What to do if you think your child has the flu
We are in the thick of influenza season now, and so it’s natural that if you hear your child start coughing, you wonder: could this be the flu? The flu is different from the common cold, but it’s not always easy to tell them apart, especially at the beginning. The flu usually comes on suddenly, and its symptoms can include fever, runny nose, cough, sore throat, headache, muscle aches, feeling tired, and generally just feeling rotten. Some people have vomiting and/or diarrhea, too. Not everyone has all these symptoms, and the illness can range from mild to severe. So what do you do if you think your child might have the...

Does the Flu Vaccine Work? What 62% "Effective" Really Means
JAMA has posted today a Viewpoint titled “Influenza Prevention Update: Examining Common Arguments Against Influenza Vaccination.”In this Viewpoint, the authors (from the Vanderbilt University School of Medicine) provide perspective to some of the reasons why people refuse the flu vaccination, including:The vaccine does not workThe vaccine causes the fluI have an allergy to eggsI cannot get the vaccine because I am pregnant or have an underlying medical condition or because I live with an immunocompromised person.I never get the flu/I am healthy I was disappointed when Dr. LaPook on a recent CBS Evening News progra...

Allergies? Common cold? Flu? Or COVID-19?
With so many of us wrestling with fears and unknowns surrounding the coronavirus pandemic, every throat tickle, nose drip, or cough is suspect: do I have coronavirus? By now, we all know that COVID-19, the illness caused by coronavirus, can cause severe, life-threatening symptoms, although the majority of people who have it will experience a mild to moderate version. Of course, it is spring, so many people may be experiencing their annual springtime tree pollen allergies. Colds also remain common, just as was true before the coronavirus. And although influenza season is coming to an end, perhaps you’ve wondered if some o...

Here we go with bird flu again
Every few years, a strain of bird flu becomes deadly to us. This year, the strain is H7N9 and it's already taking lives in China. Forgive my skepticism, but China may report only 13 deaths, but the true death toll could be higher. I suspect that it's higher. So, what do we know about this bird flu? I'd recommend the influenza A H7N9 resource page on the New England Journal of Medicine: http://www.nejm.org/page/influenza Of course, the CDC is also maintaining a page on Avian Flu. This year, I suspect that social media monitoring/analytics may provide some valuable insights if this flu strain spreads globally.

H1N1 influenza in Aosta, Italy
I am off to Italy for a short break later this year, lucky me, so am trying to resuscitate my holiday Italian.   And so I have downloaded the Android app for La Stampa (I tried two others but the full text wasn't free to read - cheapskate!).  And I spotted this piece about cases of H1N1 influenza in Aosta, northern Italy.Other Italian sources (like ANSA) are reporting the same, but I can't find anything in English anywhere, or anything in Dutch or French.It seems that one man has died, although he may have been in hospital with other conditions (the sentence with "pluripatologie", but not sure), and a woman ...

First human infections with avian influenza H7N9 virus
Fourteen people in China have been infected with avian influenza H7N9 virus, leading to five deaths. This avian influenza virus has never been isolated from humans. Influenza A viruses with the H7 hemagglutinin protein circulate among birds, and some, such as H7N2, H7N3, and H7N7, have been previously found to infect humans. It is not known how the individuals in China acquired the H7N9 virus. Some of the infections have occurred in Shanghai, where a similar virus was found in pigeon samples collected at a marketplace in that city. It is not clear what types of pigeon samples tested positive for the virus, nor is it known...

A single amino acid change switches avian influenza H5N1 and H7N9 viruses to human receptors
Two back-to-back papers were published last week that provide a detailed analysis of what it would take for avian influenza H5N1 and H7N9 viruses to switch to human receptors. Influenza virus initiates infection by attaching to the cell surface, a process mediated by binding of the viral hemagglutinin protein (HA) to sialic acid. This sugar is found on glycoproteins, which are polypeptide chains decorated with chains of sugars. The way that sialic acid is linked to the next sugar molecule determines what kind of influenza viruses will bind. Human influenza viruses prefer to attach to sialic acids linked to the second sugar...

Attenuated influenza vaccine enhances bacterial colonization of mice
Infection with influenza virus is known to increase susceptibility to bacterial infections of the respiratory tract. In a mouse model of influenza, increased bacterial colonization was also observed after administration of an infectious, attenuated influenza virus vaccine. Primary influenza virus infection increases colonization of the human upper and lower respiratory tract with bacteria, including Streptococcus pneumoniae and Staphylococcus aureus. Such infections may lead to complications of influenza, including pneumonia, bacteria in the blood, sinusitis, and ear infections. One of the vaccines available to prevent inf...

Seriously, Just Get The Flu Shot
Did you get your flu shot yet? Our family was a bit delayed in getting our shots this year and sure enough – yep, one of the girls got it! Watching my very healthy 12-year-old struggle with a high fever and crazy coughing was tough.  I can’t imagine the toll it would take on someone who isn’t as healthy. The rest of us rushed out and got our flu shots.  So far, (do you hear me knocking on wood?) none of the rest of us have fallen ill. I know – no one likes a shot. Yet, a little poke in the arm is a small price to pay to avoid a potentially fatal infection. Many people are confused about the flu an...
