This isn’t my understanding at all. There are several antibiotics that are given as standard treatment for active TB and there have been for over 50 years. There are now drug resistant strains, but we also have 2nd gen antibiotics and rapid tests that can tell exactly which strain of TB you have (and so what antibiotics you should take for treatment). The major obstacle in curing TB worldwide is lack of funding, not lack of medicine.
Edit: I want to emphasize that I’m not an expert. My understanding is also that antibiotic treatment is no guarantee of a cure, especially for people who are immunocompromised or malnourished, and even more so for people who don’t have access to newer diagnostics that can tell you if the TB strain is drug resistant. But I believe a complete treatment (many months with no interruptions) with the correct antibiotics for a particular strain of TB has a high rate of success.
I’m not a financial advisor, but if you’ll need to use the money you’ve invested any time soon, then please take out your money now and don’t invest in something as volatile as stocks. Otherwise if you’re investing for the next 15+ years, then trying to time the market is generally a bad idea since the market is often irrational in the short run.
Bonds are a good option right now if you have medium-low risk tolerance. Interest rates are relatively high and prices will probably be rising if this recession comes as we all expect.
