My thanks to Dr. Ian M. Mackay from the University of Queensland in Australia for the link to his blog – Virology Down Under - where he has put together a very helpful timeline, and commentary, on the H7N9 cases reported out of China (link).

 

In addition to providing extensive background information on human viruses, his blog also covers breaking news.  

 

Some recent posts include:

 

Break news of interest to virology

 

 

I’ll definitely be adding Ian’s blog to the list of resources in my side panel.

Online Virology Course: 2013

Virology Course 2013


# 6905

 

A little more than 3 years ago in an Online Virology Course, I wrote about Vincent Racaniellos taping and sharing on the internet of his spring virology lectures.

 

Racaniello, who pens the excellent virology blog and hosts the always fascinating This Week In Virology (TWiV), This week in Parasitism (TWiP) and This week in Microbiology (TWiM) podcasts, is a professor of virology at Columbia University.

 

On Friday Dr. Racaniello announced the start of his 4th year posting his lectures in A virology course for all, explaining:

 

Readers of virology blog can watch every lecture in the course. You will find a videocast of each lecture at the course website, at my YouTube channel, and at iTunes University. The complete 2012 version of this course is available online, at iTunes University, and YouTube.

 

Follow this link to Vince’s blog for more details. 

 

I watched many of the first season of lectures, but as age and time conspire against one’s memory, I look forward to this year’s offerings as a refresher course.

 

The first three lectures for 2013 are now up, and ready for viewing – something I’ll be doing later today.

  

While these lectures are geared towards advanced undergraduates, and parts may be a bit advanced, the great thing about the internet is you can pause and look up terms you don’t fully understand.

Based on the videos I saw in 2010, I happily recommend these lectures to disease and science geeks everywhere.

Do1Thing: A 12 Step Preparedness Program

Major Disasters In the United States - Credit FEMA

 

 

# 6827

 

While government agencies like FEMA and Ready.gov  continually urge people to become better prepared to deal with emergencies and disasters, many people end up doing little (or nothing) because the task seems so daunting.

 

To go from unprepared to prepared doesn’t happen overnight.  It requires thought, effort, some modest expenditures and time.

 

Each September FEMA & Ready.gov promote National Preparedness Month – and I devote a good deal of this blog to that effort – but the best time to get started in preparedness is now.

 

And to help you along in this task is the web-based Do1Thing project, which was recently featured in the CDC’s Public Health Matters Blog.   This is a 12-step program that asks you to just do 1 thing each month to become better prepared.

 

Register on the site (which is free) and you’ll receive monthly email reminders and encouragement, to help you meet the goal of becoming better prepared over the next year.

 

A few excerpts from the CDC blog, then I’ll return with more.

 

Do 1 Thing in 2013

Categories: General, Natural Disasters, Preparedness, Response

 

January 1st, 2013 8:00 am ET  -  Blog Administrator

New Year’s resolutions have been on our mind at CDC’s Office of Public Health Preparedness and Response.  Through the halls you will hear talk of losing weight, reading more, spending less money… the list goes on and on.  But let’s be honest, resolutions can be hard to keep.  This year, make a resolution you can keep.  Commit to improving your preparedness skills and resources for emergency situations.

 

The idea of preparing for an emergency may seem like a daunting task.  Some shrug and assume that emergency responders will be there to save the day.  The truth is, when disaster strikes, emergency responders are slammed with calls for help.  It may be left up to you.  Be ready and prepared to help yourself, your family, and your neighbors.

 

Start small.  Focus on one topic area each month for the year.  The Office of Public Health Preparedness and Response has recognized the Do 1 ThingExternal Web Site Icon project as a community effort that reflects and embodies the Whole Community approach to emergency management.  Do 1 Thing, a web-based preparedness program, encourages participants to become better prepared by tackling one topic each month.

(Continue . . . )

 

 

Do1Thing also has a Youtube channel where you’ll find a dozen audio files (each approx 4 minutes) giving the basics for each month of preparedness, along with a dozen 30 second PSA videos. 

 

You can visit it HERE.

 

The first step for January is to MAKE A PLAN.  In February you’ll store enough water for family and pets to last 72 hours, and in March you’ll make decisions about sheltering in place or (if necessary) evacuating to another location. 

 

By following these 12 monthly steps, by the end of the year, you and your family should be well prepared to deal with most emergencies and disasters.

 

While major disasters don’t happen every day, the United States experiences one – on average – every five to seven days.  In 2011 there were a record 99 major disaster declarations.

 

It doesn’t take a `doomsday’ type event to ruin your whole day.  Tornadoes, floods, winter storms, power outages, earthquakes, wildfires, and hurricanes are all too common occurrences.  


When things go bad in a hurry, the advantage goes to those who are best prepared.

 

Which is why FEMA, Ready.gov, the HHS, CDC, and dozens of other agencies and organizations all encourage citizen preparedness.

Racaniello On H5N1’s Fatality Rate

 


# 6050

 


Vincent Racaniello, Professor of Microbiology at Columbia University Medical Center and host of 3 weekly podcasts (TWIP, TWIM and TWIV), also pens the outstanding Virology blog.

 

Today he has a post on the supposed CFR (Case Fatality Ratio) of the H5N1 virus. 

 

The mantra in the popular press is that bird flu kills `60% of those infected’. We seen it used a lot over the past month, particularly in cautionary media stories regarding the dangers of bird flu research.

 

It’s a simplistic view, of course, because we don’t know how many mild or even asymptomatic cases occur that are never reported.

 

This is something we’ve discussed often, including last December, in Study: Subclinical H5 & H9 Infections In Humans, where we saw a report out of China on the detection of antibodies to both H9 and H5 avian influenza viruses among a small number of villagers in and around Beijing, China.

 

Similarly, last September we saw a study that reported the results of serological testing conducted in a rural village in Thailand in 2008 (see Bangladesh To Share H9N2 Bird Flu Virus). 

 

Out of 800 villagers tested, the authors found 4.7% were seropositive for the Hong Kong H9N2 avian strain, 5.6% had antibodies to A/Thailand/676/2005 H5N1 bird flu, and 3.5% were shown to be seropositive to A/Thailand/384/2006 H5N1.

 

The implications of these studies are that human infection with these avian viruses – while still pretty rare – probably occur more often than current surveillance and reporting suggests.

 

And if true, that would dilute the 60% CFR number.

 

Perhaps considerably.

 

As Professor Racaniello explains, until we can get a good handle on how many `mild or asymptomatic’ infections occur, we really can’t determine the true fatality rate of the virus.

Referral: CDC Blog On Puerto Rico’s 2010 Dengue Epidemic

 

 

# 5757

 

 

Although it ended last December, for almost all of 2010, Puerto Rico was embroiled in a serious dengue fever epidemic.This time last year close to 900 infections a week were being reported.

 

Thankfully, cases this summer are running below average.

CDC Dengue Surveillance – Week 29, 2011

 

This morning I ran across an account of what it was like dealing with this outbreak on the CDC’s Public Health Matters blog. It is written by a young EIS (Epidemic Intelligence Service) officer named Tyler Sharpe, who was stationed at the CDC Dengue Branch in San Juan for much of this outbreak.

 

Not only does this first hand account help to `humanize’ an event we pretty much followed on charts and graphs, it provides a rare glimpse at what it is like to be a part of the EIS during a public health crisis.
