Active TB is very dangerous but thankfully, it is treatable with medications.
Your question isn't too clear so I will be general with what active TB is and it's symptoms.
First off, TB is highly contagious, as it is spread through particles from our mouth, nose. Before active TB begins, the virus is latent without our body, or dormant, meaning that it's not active but it's sitting in your body waiting to become active.
TB is usually restrictive to the lungs and causes severe coughing and most times it's presented with coughing up blood in the more advanced process of the disease.
TB typically presents, also with night sweats, decreased in appetite, high fever, lethargy and chest pain due to the severity to coughing causing costochondritis.
