#TB
#PostAcute
#Reactivation
The TB paradigm was wrong in 2 ways
We overestimated reactivation (molecular tools showed 30-80% is recent transmission in endemic areas)
We assumed the distinction mattered clinically (it doesn't)
But timing DOES matter epidemiologically. Here's ?

#Nipah
The condition of two nurses, who tested positive for the Nipah virus in Kolkata, remain critical
The confirmed cases of Nipah virus include two nurses, a doctor, & a health staff member.
100 quarantined @organicbotanic.bsky.social

India rushes to contain deadly Nipah virus outbreak after five cases confirmed
West Bengal & Kerala in India have had a history with Nipah Virus Disease as cases have been found in past as well

#TBRiskFraming
How it is said matters
“Given current 2nd-line drug availability & costs, expected MDR-TB mortality is 40% "
Reality: 2nd-line drug cost $1,000-5,000 for 18 month t/t while generic would cost $100-500
40% mortality is pharmaceutical profit prioritization, not biological inevitability

Covid as Protective factor?
Resilience?
I thought resilience was a socio-cultural construct
Precisely why I have reservations with evidence alone science, evidence constructed through statistical power

Malnutrition-known to be a risk factor for making TB symptomatic.
But our recent experience using a case-control design saw that this & other known risk factors may actually be over exaggerated @organicbotanic.bsky.social @elhopkins.bsky.social @microlabdoc.bsky.social

While climate science is the earliest to recognise “Outliers/extreme weather conditions” as critical, is it too late to prevent the impact of these?

It is not just about rising temperatures or melting glaciers
It is also about patterns/trends/prediction of rains, snow & sunshine
Single-day rainfall for the month of August in nearly a century

Jammu records 190.4 mm rainfall in 24 Hours, second-highest August downpour in nearly 100 years
Heavy downpour triggered waterlogging in several parts of the city, disrupted traffic and raised concerns over the flood situation in low-lying areas

This infection is not just one-off event & we did underestimate it
SARS-CoV-2 infection results in increased macrophage numbers & extensive formation of enlarged lipid-laden macrophages or foam cells

SARS-CoV-2 infection induces pro-fibrotic and pro-thrombotic foam cell formation - Nature Microbiology
SARS-CoV-2 infection can lead to sustained increased macrophage numbers and formation of enlarged lipid-laden macrophages after viral clearance. This can be prevented with antiviral treatment in mice.

In very near future, public health resources will largely be directed towards reducing impact of drug resistance & #XDRTB will partake the largest share of these & yet the rewards will be far from satisfactory

Instead of asking “who is sick?” our solution asks “is transmission happening here?”—shifting the focus from individuals to locations where airborne spread occurs
