At the end of last year, we published our report on food poisoning outbreak of rare Bongkrekic acid (BA) that occurred in a restaurant in Taipei in March 2024, affecting 33 diners; 9 of whom were hospitalized and 6 died. @robin.n.thompson

In our recent EID letter: Serial Interval and Intervention Efficiency in Pertussis Outbreak, South Korea, 2024, we re-analyzed Cho et al.'s outbreak data to recover the unmitigated serial interval — what would be expected without case isolation.

A really nice paper with a very interestingly complicated dataset. Lots of modelling details to dig into in the SI.

Recently, Taiwanese government sent a scary book asking their citizens to prepare for war. A lot of money has been spent on that book and there QR codes in it, which would not be working in case of war. Anyway, let's wish the peace will remain

I have not been really against using AI, but first time I thought of it, when I read someone's comment on another comment published in the journal. Especially, when the opening of the letter looks "familiar":

Nice preprint by David Earn and Todd Parsons (H/T
@jmccaw.bsky.social
) showing how the SIR model can be related to a more general class of renewal process models that don't assume exponentially distributed infectious period.

Epidemic Momentum
Infectious disease outbreaks have precipitated a profusion of mathematical models. We introduce a unifying concept of "epidemic momentum" -- prevalence weighted by the capacity to infect in the future...

Following the first report of African Swine Fever (#ASF) in Taiwan, here is a reminder of our paper on the 2018-2019 ASF outbreak in China. It took about 6 months to for ASF to get reported in every province of China. Long-distance tranmissions were driving the outbreak:

This NEJM episode about angioedema is quite interesting.

The patient had reoccuring of abdominal pain, and it was a mystery. One of the explanations was Familial Mediterranean fever (FMF), which was unlikely because the patient didn't report any fever.

An interesting title with "China and its provinces"

Although it assumes some external provinces, they are not part of the study: all analysis is about PRC and two SARs.

The study estimated the (constant) effective reproduction number Rt at 1.25. We have investigated a time-varying Rt, highlighting that its temporary variation can also provide important messages

Oh, the news in Independent about the largest outbreak of TB in Kanzas, but the article states that TB has two different strains: active TB and latent TB. But they are definitely not two strains, and latent TB may progress to active TB... :/

In our recent paper, we showed that the incubation period of mpox infections for the 2022 global outbreak and historical data were quite close to each other (8.1 vs. 8.2 days). However, the incubation period for clade I was relatively shorter than for clade II (7.3 vs 8.9 days).

It's of great pleasure to be a part of joint effort on trying to clarify some challenging aspects for estimating epi time intervals of infectious diseases. The project mostly led and mostly realized by Sang Woo Park and Sam Abbott (

Interesting, a study from HK: "We calculated percentages of asymptomatic cases of 41.8% among reported SARS-CoV-2 infections and 72.1% (95% CrI 70.8%–73.0%) among total (reported and unreported) infections."
