If you start seeing H5N1 viruses in human swabs - even when those humans are asymptomatic, it’s time to worry and take much more aggressive action to quarantine and sequence virus

Wastewater surveillance is one of the biggest public health advancements of the last few years. But is it ready to move beyond COVID-19 to tracking a wide variety of health threats?

Crossing Species: The Rising Threat of H5N1 Bird Flu in the U.S.

A recent case in Texas shows possible mammal-to-human transmission, a first in the U.S.

Despite the low overall risk, those in close contact with infected animals remain at increased risk.

German Health Minister Karl Lauterbach gives an update on Long COVID.

Even those getting reinfected or infected after vaccination, again have the risk of getting Long COVID.

We have many Long COVID cases, and with each wave of infections, more cases are added.

We still do not…

MedPage Today, Monica Bertagnolli on Long COVID:

'It's a terrible, terrible condition. Post-infectious, chronic post-infectious syndromes have been around as long as there've been viruses..'

'We see evidence of persistent live virus in humans...'

fascinating but also sobering. The agent can live for a long time in tissues. It can surround nerve cells, probably likely one of the ways that it produces some of its terrible symptoms such as the dysautonomia. And we have no effective way of eradicating it. Not yet.'

'One thing that's important though that's come out of several meta-analyses is there is a way to prevent it. And the way to prevent it is vaccination, and multiple vaccination is better than single to prevent long COVID.'

Bertagnolli: We see evidence of persistent live virus in humans in various tissue reservoirs, including surrounding nerves, the brain, the GI [gastrointestinal] tract, to the lung.

Our emerging data shows that the virus can persist into tissues in the long term, and I think

Culture positive samples were also produced by covid patients showing no symptoms, further evidence of the likelihood of asymptomatic transmission. 6/n

Comparing the likelihood of aerosols samples being culture positive, there is a clear size distribution – consistent with modelling assumptions that larger aerosols, with more volume, more likely to encapsulate viable virion. 4/n
