There is a higher incidence of TB in Canada in certain populations (refugees, homeless and people living in reserves). It is just a fact. If you look at the number of TB cases per the amount of refugees admitted into Canada each year the incidence rate is high compared to other immigrants. That is because they are allowed to arrive and seek treatment in Canada for their communicable diseases. If you work with the homeless population you also know that based on their living conditions they are more prone to many diseases including TB. Canada tries very hard to prevent TB from being in the Canadian population because of the rise of drug resistance and the fact that it takes a long time to treat. Many patients abandon treatment because it is long and often hard and that’s why you have a public health nurse following up with anyone who has been identified as having TB. Most physicians will not be comfortable if they are examining a patient and then discover they have TB. It just isn’t a common condition people and physicians see in the general population. If people have passed their medical many get TB when they travel home or they are part of the medical surveillance lost at public health. In many countries getting TB isn’t considered unusual or a big deal. In Canada it is. Public health doesn’t have to be bad in my city for public health workers not to make house calls. Many don’t make house calls purely for safety reasons and in larger cities people may not have vehicles or getting to numerous patients would be too time consuming. There are often local clinics that are more accessible for people or labs where people can do tests all over the city with a requisition. A lot of the work can be done over the phone. If a patient is not following the protocol the public health team may have to try and go to their home.Most people have latent TB(people pass the immigration screening easily). Only 25% of the latent cases turn active and that too in immuno-compromised individuals. Even diabetes can turn latent tb into active tb. Don't be surprised if someone drives a Merc and is being treated for TB. It's a popular misconception that TB only affects refugees, homeless and others.
It's sad that public health sucks in your city. Refugees, homeless and reserve populations are humans too, and are not in control of their situations completely. I know the sad state of affairs concerning universal healthcare here, UK is worst. People think universal healthcare is the best..No wonder that topic never wins in US elections.
Would look at the US system and how it isn’t dealing well with covid 19. Think the many countries that have universal healthcare have been reacting much better than the US. The US will likely have the most deaths, have families left with so much medical debt that they have to declare bankruptcy and many patients will only seek out help when they already very sick because of lack of insurance. Not seeking help earlier may impact their survival. On top of this many hospitals may also go bankrupt because many operate month to month and depend on relatively simple elective surgeries where patients never need an ICU as their bread and butter. Long ICU cases tend to cost more than they can bill for and most hospitals have shut down their elective surgeries and have expanded their ICU beds. Rural and public hospitals are especially at risk. Some of the large private hospitals have big endowments and have more of a cushion. Not saying the Canadian system is perfect but the US system doesn’t work.
