Preventing Hantavirus Disease - CDC Videotape (September 1994)
World-Wide Web format - February 1996

------ What is in this package?

This "multimedia" package consists of HTML files and images
that you can store on a WWW server or viewed locally using a
Web browser.  The advantages of storing the files locally are:
(1) images/sounds/movies would appear much faster and
(2) you can view them on a computer (eg laptop) without having
an Internet connection (but you still need a Web browser that can
view local files). 

The source of the text and images is the CDC videotape
"Preventing Hantavirus Disease" released in September 1994.

The purpose of the videotape is to educate the public on
this deadly disease that is transmitted by rodents.

The videotape is about 30 minutes long. The HTML files include
(verbatim) the entire script.  The images are stills captured
from the videotape. The sounds and movie were also captured
from the video.


------ What computer system and Web browser should I use?

(Graphics) Your browser has to support HTML tables and be able
to display in-line JPEG as well as GIF images. The JPEG images
are 24-bit ("millions of colors").  If you only have 16-bit color
("thousands of colors") or 256 colors on your monitor, the images
would appear best if you can set your browser to "dither" the colors.
Some browsers may not support image color dithering.  The graphics
monitor should support 640x480 resolution or higher.

(Audio and Video)  There are a few sound and movie files included.
Listening to the audio and viewing the movie are optional. 
The sound files are provided in both AU and WAV formats.  The movie
is in both QuickTime and AVI formats.  You need a sound card in your
computer connected to speakers or headphones.  You also need
appropriate software to play the audio and video files.  Consult
you Web browser documentation on how to play these sound and movie
files.   


------ How much disk space do I need?

--------------------------------------------------------------
Sub-Directory   # files   Total(MB)          Files
--------------------------------------------------------------
                  2        0.01        hanta94.htm  readme.txt
audio             8        3.43        *.au  *.wav
html             45        0.11        *.htm
images          242        1.87        *.gif *.jpg
movies            2        7.87        *.mov *.avi
--------------------------------------------------------------
Total           299       13.62
--------------------------------------------------------------
(Note: 1 KB = 1,024 bytes; 1 MB = 1,024 KB or 1,048,576 bytes) 

All the files in the html and images subdirectories are required
for proper viewing.  Together they take up a total of 2 MB.
To minimize storage space, you may omit the audio and movie files,
or only include a single format (eg AU and QuickTime only).
If you keep the *.zip files for others to download from your
WWW server, then those would take up more space.

The *.htm files are in MSDOS format with CR/LF at the end of each line.


------ How do I install this package?

To install the files on your WWW server or local drive,
first create a new subdirectory such as hanta94.
Copy the hanta94a.zip file into this directory and run (eg in DOS):
      PKUNZIP -d hanta94a.zip
The subdirectories html and images will be created.
If you download the sound and movie files (eg hanta94b.zip and
hanta94c.zip), copy them to the same hanta94 subdirectory and run
PKUNZIP:
      PKUNZIP -d hanta94b.zip
      PKUNZIP -d hanta94c.zip
The subdiretories audio and movies will be created. 
Do not change the names of these subdirectories.

If you are installing this package on your WWW server and you
want others to be able to download the *.zip files, then
leave the *.zip files in the same directory as the hanta94.htm
file--otherwise you may delete the *.zip files.


------ How do I start viewing the Web version of "Preventing
Hantavirus Disease?"

The main Web page is the file hanta94.htm.  Use the browser to
"open local file" to access this page.  On a WWW server, you can
create a link to this page from other Web pages. 


------ Are there restrictions on what I can do with these files?

No. All the images and files are produced by the Centers for
Disease Control and Prevention (CDC), Department of Health and
Human Services (DHHS), and they are in the public domain.
There is no copyright.  Feel free to copy and distribute these
files.

------ That's it!
