You’re describing diagnostics not surveillance. MALDI/LFIA give ID & phenotype. They don’t produce genomes for cross-site comparison. WGS links cases & supports regional/global surveillance- info used to target isolation, cleaning & screening. Phenotype guides treatment; genotype informs prevention👋

Rapid tests detect. They don’t link cases, map plasmids, or resolve transmission. WGS does & feeds harmonised, shareable genomes into cross-institution & global #PublicHealth surveillance. Lateral-flow assays or MALDI-TOF don’t produce genomic data, so they cannot serve that role

Think you were exposed? Call Healthline 0800 611 116 for advice before visiting care. They’ll advise on what to do & how to protect others ☎️ 😷

Were you at a “location of interest”? Check dates & follow the advice for close or casual contacts here: info.health.nz/conditions-t... 📍

Highest risk: unvaccinated people, babies under 12 months, pregnant people, & those with weakened immunity. Complications can be serious 👶 🤰 🧪

Symptoms to watch: fever (≥38°C), cough, runny nose, sore red eyes, then a rash.

If symptoms start, call your GP or Healthline first.

How can #measles spread?
Breathe the same air as an infectious person & you can catch it. The virus can linger in the air or on surfaces for up to 2 hours 🕒

Where else is ST1 hiding?

We need to start thinking about environmental & farm worker sampling to map the spread & persistence of ST1

Timeline analyses show ST1 evolving differently in people & cows

To stay ahead of emerging lineages & resistance, we need a #OneHealth lens linking human, animal, & environmental data 🌍

We expected human & bovine derived ST1 to be genomically ‘similar’

Instead we found:

🔹 Human derived ST1 = more antibiotic resistance genes #AMR

🔹 Bovine derived ST1 = a unique host-specific prophage (φSabovST1) carrying bovine leukocidins

Globally, bovine S. aureus usually belong to ST97/ST151

But in NZ 🇳🇿, ST1 dominates in humans & cattle

This unusual overlap raises big questions about possible cross-species #transmission & #evolution

#PublicHealth action worked:
🧼Hygiene issues were fixed
✅No further cases linked to the site

Genomic sequencing helped:
✔️Trace the outbreak to a single introduction
✔️Understand how it spread

#CPE isn’t just a hospital problem - it’s a community threat, but solvable

A common link kept coming up: a ready-to-eat food venue, Premises A

Environmental testing found OXA-48 #Ecoli from food handlers, some had no symptoms
One had travelled to SE Asia in 2017

The strain likely entered NZ once, then spread locally

🧵The team used #genomics to reveal community spread of #AntimicrobialResistant bacteria in New Zealand

A carbapenemase-producing E. coli was spreading
Not in hospitals, in the community

We used whole-genome sequencing to investigate & start to learn what happened
