Global estimates of paediatric TB incidence in 2013–19: a mathematical modelling analysis (post)
An article published in The Lancet Global Health estimated paediatric TB incidence and underreporting between 2013 and 2019 in countries representing more than 99% of the global TB burden.
TB remains disease of concern in South Africa (post)
Tuberculosis (TB) is one of the major causes of death in South Africa, killing thousands every year, according to surveys and experts.
‘Fighting TB in South Asia challenge in pandemic times’ (post)
Although the incidents of tuberculosis have decreased in South Asia from 5.4 million cases in 2000 to 3.8 million in 2020, the health experts believe that the still staggering numbers call for effective policies.
Why has the incidence of TB not reduced in London during the COVID-19 pandemic? (post)
The rate of TB in London, UK, has not reduced during the COVID-19 pandemic. This might be surprising given that TB is airborne, and suggests important lessons about the transmission and treatment of the disease.
Culture-based screening in US-bound individuals reduced multidrug-resistant TB incidence (post)
Overseas culture-based tuberculosis screening in U.S.-bound immigrants and refugees substantially reduced the importation of multidrug-resistant TB into the U.S., researchers reported.
New study identifies African ‘hotspot’ for highly infectious diseases (post)
A regional corner of Africa is a hotspot for cases of HIV, tuberculosis and malaria, prompting researchers to call for targeted health support rather than a national response.
Demographic, mycobacteriologic features in subclinical pulmonary TB (post)
In high-income countries like Canada, patients with subclinical pulmonary tuberculosis (TB) are a heterogeneous group, accounting for one-fifth of all pulmonary TB culture-positive cases, according to findings published in Chest.
Exploring ancient TB transmission chains (post)
Tuberculosis is the second most common cause of death worldwide by an infectious pathogen after Covid-19, but many aspects of its long history with humans remain controversial. Researchers at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and Arizona State University in Tempe, USA, found that ancient tuberculosis discovered in archaeological human remains from South America is most closely related to a variant of tuberculosis associated today with seals, but surprisingly these cases were found in people who lived nowhere near the coast. This implies that these cases were not the result of direct transmission from seals, and instead one, or more, spillover events were likely to be the primary drivers of human infection.
Ukraine war likely to cause infection outbreaks that will spread beyond borders (post)
Every day we see stark images of the war in Ukraine — bombed-out buildings, explosions, and bodies lying in the streets. But there's another, less visible war — against the bacteria and viruses that are gathering their forces together. They, too, will infect parts of the population and may spread throughout Europe. Here's what Ukrainians — and their neighbors — are facing on the infectious disease front.
Ancient DNA confirms marine mammal tuberculosis strains were found in inland people (post)
Tuberculosis is the second most common cause of death worldwide by an infectious pathogen; COVID-19 is the first. However, many aspects of TB's long history remain controversial.
