Doesn't state which areas are moderate to high-risk for travelers’ diarrhea, which most travelers will contract. Doesn’t offer advice on routine vaccines such as MMR for areas with community outbreak of measles. This is not a good app for beginners or experts in travel medicine. It’s too basic and should be a free app. ### 1/5 — No free *2019-05-07* You need to pay to get informarion ### 5/5 — Clarification *2018-10-11* Clarification on all the bad reviews. The info is great and if you live in the developing world and see patients it is invaluable. Great info without a WiFi. It is a trial version. It lists all the topics you can see with a subscription. I think people just want everything for free nowadays. It’s a great app. **Developer response:** Thank you for taking the time to write this thoughtful review. We are so glad to hear you find this to be a valuable resource. ### 1/5 — Total waste *2018-06-20* Makes you pay for info easily obtained free from CDC website. Don’t bother. ### 1/5 — Making you pay for a free product *2018-05-13* This is a government document, free online, but these cons are selling it to you. Don’t be scammed. ### 1/5 — Don’t waste your time - go to CDC instead *2018-04-05* Complete waste of time. The “previews” are no such thing and nearly all information is behind a $30 paywall. Don’t bother with this cash grab. Go to the CDC website where all the information is available freely. It is disgraceful that a public health info resource like this that is already paid for by taxpayers and donations *and* that has all the info for free on the CDC website is being sold here for a hefty profit. Absolutely shameful behavior. A minor convenience fee of $1-$3 or so would be perfectly fine, but present cost is criminal. ### 5/5 — Pricy, But Great Information ! *2018-03-10* If you travel the world, especially in the tropics, the C.D.C. “Yellow Book” for travellers has lots of info on tropical diseases and other diseases, and the preventive actions and vaccines to help prevent the diseases. Yes, it’s pricy, but I recommend it. ### 1/5 — Not really a preview *2018-01-12* I don’t think any reasonable man would call this a “Preview.” Once you waste your time and data downloading the app, you will ONLY have access to a “water disinfection for travelers” document. If you want to know what the app contains and how it functions you’ll have to pay $30 or just go to the CDC website where it’s free. **Developer response:** We appreciate your feedback. The current Preview version offers 11 available entries in the "Contents" section and 46 available entries within the "Topics" section to aid in a user's decision whether to purchase. Purchasing an account unlocks the remaining content and also grants the ability to add Favorites and Notes so that you can easily return to entries that are important. Also, once the content has been synced to your device, it is accessible without an internet connection. These perks set the mobile app apart from accessing the content online. ### 1/5 — Scam *2017-09-10* This "app" is free to download but does not come with usable data. In order to make it usable, you must pay $29.95. So, the app is not free. It's 29.95 app. Take that into consideration before you download. ## Frequently asked questions about CDC Yellow Book ### What is the CDC Yellow Book app?
