As COVID cases rise in China and protestors challenge policies, note:
the country does not have the immunity the rest of the world does - no mRNA vaccines, little infection-derived immunity.

Of those most vulnerable, over 80, only 40% have had the 3 vaccine doses needed
1/n Immunity derived from vaccination and infection cushions the rest of the world

China does not have the same immunity

It also has an older population

Two populations of similar sizes - China (1.44B) and India (1.38B) - and China, after decades of 1 child policies - is older

What are the caveats of the ACAM2000 vaccine (replication-competent vaccinia virus) for monkeypox/smallpox? The stocks are much larger but why not used?
- Contraindications for many (see next tweets)
- Need to cover vaccine site to avoid spread to others (given contraindications) So for whom would ACAM2000 be a concern?
From the US CDC:
These include those at high risk for heart disease (given risk of myocarditis), eczema or other exfoliative skin conditions, immunosuppressed, HIV+, use topical ophthalmic steroids, pregnant, breastfeeding, under 1,

If you've never seen what diphtheria, tetanus, or polio can do, you're lucky.

Your parents or grandparents or great grandparents weren't so lucky.

These are horrible diseases with no good treatments. This is why there are vaccines.

A little reminder of the reality: Tetanus - each movement leads to painful waves of twitching. the patient is smiling sardonically, taking shallower and shallower breaths. others say they're fine. They look happy, not struggling for breath, just slowly silently suffocating, unable to move. it's a horror film.

Current monkeypox cases detected do not correspond to real time transmission
1) We are playing catch up identifying patients not recognized before
2) Monkeypox serial intervals* are much longer than say for COVID
Rising cases can still mean we are finding what we've been missing *Serial Interval - time from illness onset in primary case to illness onset in secondary case
With some diseases this is short. 2 cases today may mean 4 new cases in 2 days. Other diseases have short incubation periods. With monkeypox 6-13 days(5-21 range)

Another thing to keep into account:

The US has lost more to COVID than to the 1918 flu

Over 1 million have died from COVID in the US, while
675,000 died from the 1918 flu in the US
cdc.gov/flu/pandemic-r… Quote "That’s not to say that the 5 million people who’ve died from COVID are insignificant, but we are also still far below the deaths that occurred in 1918 which is another thing to keep into account"
Globally, 5 (or 6+) million from COVID is less than 50 million from 1918 flu

Infectious disease control is about good governance -about managing resources and infrastructure, responding to public, and listening to and protecting the vulnerable and marginalized. Cholera is the classic example. Climate change will increase the pressure. 1/n "Cholera outbreaks in Pakistan kill 6 and infect hundreds amid a pummelling heat wave and water shortages"

Fiji has had a run of lepto cases associated with flooding (and rats). There have been over 2000 diagnosed cases, close to 700 hospitalizations, and at least 40 deaths including teenagers. This is up sharply from the last few years.

Anthrax is not as uncommon as one might think. It is a vaccine preventable disease of livestock that can affect those with animal contact. Largely only farm/abbatoir workers have exposures. In the 1950s, 20-100K were infected, by 1980s, 2K a year were worldwide. Sources

?🇦🇷🇲🇦 Case in UAE may be from a separate, unrelated introduction from West Africa.

Most monkeypox outbreaks have had substantially shorter chains of transmission than seen here. Infections are usually sporadically spread to humans but maintained in rodents, other wildlife.

Climate change will have many effects, one is a change in the incidence of infectious diseases

In 2013, researchers looked to see the impact of deforestation and climate change on animal reservoirs in Central Africa to predict monkeypox risk.

Not surprisingly in hindsight: 1/n The paper elaborates "The question whether MPXV will be transmitted to humans in areas that will become more favorable to MPXV reservoir species is at least partially dependent on human behavior"
