INTRO: Although it is a widely known scientific fact that infectious diseases emerge and re-emerge due to climate change, a study which included the involvement of the UAB published in PlosOne reveals that 48.9% of the population surveyed are not aware of this relation.

The transmission of specific infectious diseases have been altered by processes linked to climatic and environmental anomalies. An increase in infectious outbreaks is expected to be seen in mild climates due to global warming, and the alterations in climate patterns, such as El Niño, are modifying the presence, density, strength and dynamics of transmission of many viruses and pathogens.

Understanding how climate variability affects the transmission of these diseases is important for both researchers and the general public... (MORE)

EXCERPTS: . . . We have two main parts of our adaptive immune response: B cells and T cells. Both of these cells can generate “memory”. We’ll talk about B cells first. They make antibodies, which latch onto and destroy disease-causing agents such as viruses and bacteria.

A team of researchers from Australia, led by Menno van Zelm at Monash University, published a preliminary study last week showing the body can generate memory B cells specific to SARS-CoV-2. The research showed these cells last at least eight months, and likely even longer. This means these memory B cells could still rapidly produce antibodies against SARS-CoV-2 eight months post-infection, if the person were to be exposed to the virus again (although this work has not yet been peer-reviewed so should be treated with caution).

[...] There have been just 26 confirmed cases of reinfection reported worldwide so far, according to a COVID reinfection tracker by Dutch news agency BNO News (although the true tally is likely higher). With 60 million people infected globally so far, reinfection therefore seems to be a very rare event.

What about T cells? These are cells that bind directly to infected human cells within the body and destroy them. All infected cells smuggle out bits of the invading pathogen onto their surface, as a kind of “SOS” signal that allows T cells to find the hidden enemy. [...] A ... recent study, published as a preliminary report last week from researchers in China and Germany ... showed T cell memory responses were still present nine months after infection.

So what does this all mean going forward? It would seem SARS-CoV-2 is not like its normal common cold coronavirus cousins. People’s immune responses to common cold coronaviruses typically don’t last very long, meaning we typically get reinfected by 12 months.

But it’s clear people’s immune systems can “remember” and respond to SARS-CoV-2. [...] So, people who’ve been naturally infected with SARS-CoV-2 can expect reinfection to be rare. If it does occur it will probably result in very mild disease, but otherwise they should be fully protected for at least eight or nine months after their first infection.

But we still don’t know what would happen if someone was re-exposed after this timeline — only time will tell... (MORE - details)

That's just a Trojan horse for big government takeovers, just like all climate alarmism. Here, they're just leveraging the work done to fearmonger over Covid.

You reading this SS and C2?

I've been talking about T-cell immunity for months now. T-cells account for preexisting Covid immunity/resistance due to past exposure to other coronaviruses. Covid may be a "novel" coronavirus for other reasons than being a newly identified strain.

But let's all panic and destroy the global economy until we know for sure [/sarc].
