Solution
The best course of action for individuals exposed to TB is to place a PPD (Purified Protein Derivative) now and repeat in 3 months. This is because it can take up to 3 months for the body to mount an immune response to TB and show a positive PPD test. Therefore, a test done immediately after exposure may yield a false negative result. A repeat test in 3 months will help confirm whether the individual has been infected. If the second PPD test is positive, further evaluation with a chest x-ray and possibly treatment with isoniazid would be the next steps.
