HIV among US youth

The Centers for Disease Control and Prevention has released its latest estimates on the number of new HIV infections in the United States:

HIV remains a serious health problem, with an estimated 47,500 people becoming newly infected with the virus in the United States in 2010. Youth make up 7% of the more than 1 million people in the US living with HIV. About 12,000 youth were infected with HIV in 2010. The greatest number of infections occurred among gay and bisexual youth. Nearly half of all new infections among youth occur in African American males.

Included is this graph of at-risk populations:

At risk for HIV

Clearly awareness of HIV and how it is spread is not enough to prevent new infections. Would an effective HIV vaccine make a difference?

A pdf version of the factsheet is available for download.

Behind the scenes: TWiV 202 at the University of Nebraska

We recorded This Week in Virology #202 at the University of Nebraska in Lincoln, Nebraska on 5 October 2012, as part of the 12th Annual Symposium in Virology. Terence Dermody, Shou-Wei Ding, Grant McFadden and I spoke about our research, and then we recorded TWiV with University of Nebraska virologists James Van Etten, T. Jack Morris, and Charles Wood.

I was impressed by the fine virology being done at the Nebraska Center for Virology, as well as the collegiality of the virology community in Nebraska, Iowa, South Dakota, and Kansas – Symposium attendees were from all of those states! I met many young virologists at the poster session and I was touched by how many of them wanted to say hello and thank us for doing TWiV.

Many thanks to all the virologists who came to the Symposium and stayed to watch TWiV. Special thanks to Charles Wood, the Director of the Nebraska Center for Virology, who participated in TWiV #202 along with T. Jack Morris and James Van Etten.

Here are some behind the scenes photographs of this short but very informative visit.
