4 ways to use the Internet to learn more about Tuberculosis:
1. Type your exact question on google, and different websites will come up that each might contain information on your question.
2. You can learn more about each symptom too, by typing it into google also.
3. The reliability of the info you find depends on if the article was made in 2005 and you read it in 2018. If the info is not up to date, it's probably not reliable.
4. Also. don't use Wikipedia or other websites, it has information that anyone of the public, can change or add. Therefore, it is not reliable.
Hope I helped. :)
