(1) This Brazil-based study on the cost-effective issue of tuberculosis preventive treatment (TPT) about disability-adjusted life-years (DALYs) is appreciated, but we don't know whether or not the cost of US$242 per DALYs is a cost-effective model for all resources in poor countries because the individual countries have their own different economic indices, which may not be applicable to the same model for all. It will need to check the situation in individual countries to set the TPT initiative. (2) Flu-like symptoms and pus-filled skin lesions are usually the clinical manifestation of Monkey Pox (mpox). This month, WHO declared mpox a global public health emergency. An outbreak has happened in the Democratic Republic of Congo with a new version of mpox, i.e., clade 1b. Certainly, there is a potential threat of cross-border transmission (human-to-human) of this infection. WHO has arranged funding to disburse among the member-state countries suffering from the outbreak. In the United Kingdom, there are a few cases have been reported. We must be vigilant to avoid any outbreak of this infection. (3) It is a challenge for all countries to deliver their primary health services (PHS) for non-communicable diseases (NCDs) today. On this challenge, a study using the convergent mix method was carried out. In this study, the contextual factors were well-identified in low or middle-income countries (LMIC) located in East Asia and Pacific, sub-Saharan Africa, South Asia, Latin America and the Caribbean countries, including less-well-off population groups, located within high-income countries. The outcome was measured by collating data from 84 similar studies. The study recommends that individual countries will require a consistent strategy to strengthen their public health care (PHC) system to improve their NCDs.
