A family member has tuberculosis (TB)?

The doctor informed us that my grandmother was hospitalized due to illness, initially in a regular ward and later transferred to the intensive care unit.
She was suspected of having tuberculosis, and it was recently confirmed.
I would like to know if family members visiting her in the hospital could be at risk of infection.
My husband has visited her several times, and my father-in-law has also gone, but the hospital requires N95 masks.
My father-in-law thinks it's wasteful to discard the N95 mask after one use, so he brought it home and reused it for his next visit.
Could this practice potentially bring the bacteria home? We have a 1.5-year-old and a 2-year-old at home, so we are concerned about the risk of transmission from family members who visited my grandmother.
We are a large family, and many of us visit her at the hospital, which adds to our worries.
Additionally, my husband has hepatitis B, so we are particularly anxious.
However, we feel we cannot avoid visiting her.
If we must go to the hospital, what precautions can we take to avoid infection?

Hello: 1.
If the visitor has appropriate protection (for example, wearing an N95 mask), the chance of transmission is very low.
General tuberculosis (TB) contacts refer to individuals who live with the patient or have been in contact with the patient for 8 hours or more in a day (including) or have accumulated 40 hours or more of contact.
They can contact the health department to obtain a referral for contact screening.
2.
Children in the household who have not been in contact with the patient and do not live with a tuberculosis patient are not considered contacts as defined.

More Info

Preventing tuberculosis (TB) transmission during family visits to hospitalized patients is a significant concern, especially when the patient has been diagnosed with active pulmonary tuberculosis. Tuberculosis is primarily transmitted through airborne droplets when an infected person coughs, sneezes, or talks. Therefore, understanding the risks and implementing preventive measures is crucial for family members visiting a loved one in the hospital.

Understanding the Risks
1. Transmission Dynamics: TB is contagious, but the risk of transmission depends on several factors, including the infectiousness of the patient, the duration of exposure, and the environment. In a hospital setting, especially in a negative pressure room, the risk of airborne transmission is reduced. However, close and prolonged contact with an infectious patient can increase the risk.

2. Protective Measures: The use of N95 masks is highly recommended for visitors in close proximity to TB patients. These masks are designed to filter out airborne particles, including those containing TB bacteria. It is essential that these masks are used correctly and not reused unless they are specifically designed for multiple uses. Reusing a mask can compromise its effectiveness and potentially lead to the transmission of bacteria.

3. Family Members' Health: Family members with pre-existing health conditions, such as your husband with hepatitis B, should be particularly cautious. Individuals with compromised immune systems or chronic illnesses are at a higher risk of contracting infections.

Recommendations for Family Visits
1. Use of N95 Masks: Ensure that all family members visiting the patient wear N95 masks. It is crucial to use a new mask for each visit. If a mask is reused, it may carry pathogens from previous visits, increasing the risk of transmission to others, including children at home.

2. Limit Duration and Frequency of Visits: Try to limit the time spent in close proximity to the patient. Shorter visits reduce the risk of exposure. If possible, stagger visits among family members to minimize the number of people in the room at any one time.

3. Hand Hygiene: Encourage frequent hand washing or the use of hand sanitizer before and after visiting the patient. This practice helps prevent the spread of germs.

4. Monitor Symptoms: Family members should be vigilant for any symptoms of TB, such as a persistent cough, fever, night sweats, or unexplained weight loss. If any symptoms develop, they should seek medical evaluation promptly.

5. Consult Healthcare Providers: If there are concerns about potential exposure, family members can consult with healthcare providers about whether they should undergo TB testing. This is especially important for those who have had close contact with the patient.

6. Protecting Vulnerable Family Members: Since there are young children in the household, it is crucial to minimize their exposure to anyone who has visited the TB patient. Ensure that those who have visited the hospital do not have close contact with the children until they are sure they are not infected.

Conclusion
While the risk of transmission exists, it can be effectively managed through proper precautions. Family members should prioritize their health and the health of their loved ones by adhering to recommended guidelines. Open communication with healthcare providers can provide additional reassurance and guidance tailored to your family's specific situation. By taking these steps, you can help ensure that visits to your grandmother are safe and supportive while minimizing the risk of tuberculosis transmission.
