Thanks for being with us.
infection get spread through the air when people who have an active TB
, sneeze, or otherwise transmit respiratory fluids through the air.It does not matter whether tuberculosis is sputum positive or negative though risk is higher with sputum positive cases.Transmission should usually occur from people with active TB (sputum positive), those with latent infection are not thought to be much contagious.
People with prolonged, frequent, or close contact with patient with TB are at particularly high risk of becoming infected, with an estimated 22% infection rate.The probability of transmission from -one person to another depends upon several factors, including:--
-number of infectious droplets expelled by the carrier,
-effectiveness of ventilation,
-the duration of exposure,
-virulence of the M. tuberculosis strain,
-level of immunity in the uninfected person.
The cascade of person-to-person spread can be circumvented by effectively segregating those with active TB (sputum positive) and putting them on anti-TB drug regimens. After about two weeks of effective treatment, subjects with nonresistant active infections generally do not remain contagious to others.
Lump in neck will not transmit the infection by direct contact.
If she is sputum positive it is better to avoid close contact till completion of 2 months of TB treatment.Get sputum testing done after 2 months and if it is negative then you may have close contact.
You can plan for pregnancy
and child after completion of 2 months of TB treatment as most of the drugs used for non resistant TB are safe during pregnancy but my suggestion is better to avoid pregnancy till completion of TB treatment for 6 months.
Tuberculosis never gets transmitted to child during pregnancy or child birth.
If she has undergone sputum culture
sensitivity and found to be multi-drug resistant TB ,she needs to be isolated and pregnancy should be avoided till completion of TB treatment as most of the drugs used for MDR-TB are teratogenic and have serious side effects.
Hope you could be able to take decision with this information.
Wish you and your wife good health.
