Budding infectious disease modellers:

We're running our intermediate-level infectious disease modelling short courses at the London School of Hygiene and Tropical Medicine. Each course is 4 days, and we're running them over the first two weeks of September.

After three years of conflict, Sudan is facing the world’s largest humanitarian crisis. 21 million people require urgent health assistance.

WHO calls for the protection of health care and safe access to everyone in need. Above all, people in Sudan need peace.

Health needs in Sudan - Around 4 million people are acutely malnourished - Diseases such as malaria, dengue and measles are spreading - Close to 40% of health facilities are non-functional

WHO’s Response in Sudan - WHO helped contain two cholera outbreaks - 4.1 million patients treated in hospitals, primary health centres & mobile clinics - 46 million children and adults vaccinated against cholera, polio, diphtheria, measles and rubella - 118 000 severely malnourished children treated in stabilization centres - 3300+ metric tons of medical supplies and medicines delivered

Three years of war in #Sudan have disrupted basic services, displaced millions and devastated the health system.

Sudan is facing the world’s largest humanitarian crisis marked by disease, hunger, displacement & despair.

Sudan's people need peace.

Massive devastation following the Israeli strikes across Lebanon.

Homes destroyed. Communities shattered. Many lives lost.

Children reported among the victims.

Civilians, in particular children, must be protected at all times, and international humanitarian law must be fully respected.

I am extremely confused as to why the UK government and police are saying Grok’s mass-scale CSAM generation is an issue for Ofcom.

This isn’t about X failing to moderate CSAM, which is an Online Safety Act issue. It is about the company and its technology being actively involved in its generation.

We systematically reviewed molecular epidemiology studies looking at strain discordance in pairs of people with TB disease and history of household contact

We found 30 studies from 18 countries. Excluding 4 studies at high risk of bias, we had data on 1544 household case pairs

Tuberculosis- learning about experience with nutritional supplementation (TB LENS): Perspectives on a nutritional supplementation for persons with TB and their household contacts Undernutrition is a major driver of the tuberculosis (TB) epidemic, with one in five TB cases worldwide attributable to undernutrition.

Everyone in TB talks about “nutrition matters.”

But what happens when you actually ask households with TB what kind of nutritional support works for them?

We did exactly that through the TB LENS qualitative study in South India.
