Household contacts of TB patients aged 60 years or older were 2.2 times more likely to develop latent tuberculosis infection than household contacts under 60 years of age. The results show that the rate of latent TB of household contacts with pulmonary TB patinents is 22.3%, it is necessary to further strengthen the diagnosis of latent tuberculosis infection in the group of household contacts with pulmonary tuberculosis patients, especially those aged 60 years and older.
