Sars CoV2 & Malaria

SC2 spike protein shares gene sequence homologs with Malaria.
Both organisms invade red blood cells.
Both use TfR and CD44.
It might be interesting to compare microscopic images of RBCs in Malaria and Covid.

2/ 🧵 Where does the word malaria originate from?

PMID: 11053494
3/🧵 Malaria is an Italian word composed of “mala” and “aria,” meaning bad (malus) air (aeris). It was first used to describe a fever (miasma) mistakenly attributed to exposure to poisonous air.

#disease risks in the new #IPCCReport

Climate change and variability are facilitating the spread of:
- #chikungunya virus in North, Central and South America, Europe and Asia
- tickborne #encephalitis in Europe
- #RiftValleyFever in Africa
- #WestNile fever in south- eastern Europe, western Asia, the Canadian Prairies, and parts of the USA
- #LymeDisease vectors in North America and Europe
- #Malaria in East and Southern Africa
- dengue globally
#Dengue risk will increase with longer seasons and wider geographic distribution in Asia, Europe, Central and South America and sub-Saharan Africa, potentially putting additional billions of people at risk by the end of the century

𝟭𝟵𝟴𝟬:Wojciech “Al” Krotoski et al publish a report in the British Medical Journal describing a dormant liver stage of #Plasmodium cynomolgi in Rhesus macaques. These dormant liver stages, called "hypnozoites" are postulated to be the cause of relapses of this #malaria species Image

𝟭𝟵𝟳𝟯:In 1973, Thomas A. Miller of the University of Glasgow Vet School, had his canine hookworm (Ancylostoma caninum) vaccine approved for commerical use in the US. Though discontinued in 1975, Miller's work has informed hookworm vaccine research to this day! @BAVet_Parasitol Image
𝟭𝟵𝟳𝟰: In Oct '73, Dr Dan Jones of the Bascom Palmer Eye Institute in Miami introduced Acanthamoeba spp. as a human ocular pathogen to a meeting of the Ocular Microbiology & Immunology Group in the USA. Months later, in 1974, Nagington et al. would publish the 1st case studies Image

𝟭𝟵𝟳𝟬: It was in 1970 that the full life cycle of #Toxoplasma gondii was described for the 1st time by Frenkel et al. Nowadays, the micro- and macro- gametocyte stages in the cat intestine are rarely studied, so the Frenkel et al. (1970) micrographs are still informative. Image
𝟭𝟵𝟳𝟭: A year that would forever change the field of #malaria research. In 1971, Prof Youyou Tu of the China Academy of Chinese Medical Sciences in Beijing, would use ether to extract "qinghaosu" from Artemisia annua L. leaf extract. In English: Artemisinin. @womeninmalaria Image

In 𝟭𝟵𝟲𝟲, the eminent parasitologist P. Cyril C. Garnham published his "magnum opus", the 1132-page encyclopaedia of #malaria parasites, "Malaria Parasites and Other Haemosporidia". After 56 yrs, images from this book are still used as references across the world. #Plasmodium Image
𝟭𝟵𝟲𝟳- what a year! In 1967, Ruth Nussenzweig & colleagues released a @Nature paper showing that X-irradiated Plasmodium sporozoites produced protective immunity against #malaria in mice. This study sparked research that would result in the identification of CSP (1/3) Image

Sehr schwer zu vermitteln, aber wichtig: *JEDE* #Impfung hat das Potential, eine Infektion komplett zu unterbinden– keine ist dabei perfekt. Extrem gut: #Masern-Impfung; nicht sonderlich gut u.a.: #Malaria, #Influenza, #COVID19. Abgesehen von kompletter… 1/3
…Verhinderung der Infektion („sterile Immunität“) schaffen es Impfungen aber, den zu zu erwartenden Verlauf der Krankheit abzumildern und abzukürzen. Dadurch bestenfalls auch verminderte Möglichkeit der Weitergabe (weniger Erregerlast, kürzere Dauer), aber auf jeden Fall… 2/3
…verminderte #Krankheitslast in einer geimpften Population. Wie wichtig das sein kann, siehe z.B. auch Diskussion um Malaria-Impfung ⬇️.

Who's ready for another jab in March? Roll up your sleeve (again) for #Pfizer 1.1:

CEO Albert Bourla, Jan 10, 2022: "And we know that the 3, the 2-dose[s] of the #vaccine, offer very limited protection, if any."

#4IR #BiotechEconomy #GeneEditing #mRNA #Crispr

Thread 👇
Bourla con't: "The 3 doses w/ the #booster, they offer reasonable protection against hospitalization & deaths... Now, we are working on a new version of our vaccine, the 1.1 [] that will cover #Omicron as well."

Bourla: "... we are waiting to have the final results. The vaccine will be ready in March, & [] we'll be able to produce it massively."

Yahoo: "I want to quickly talk about the #kids... under 5... the company has said that it's going to need to be a 3-dose vaccine..."

"It’s a pleasure to welcome our friends from the Palais back to WHO.
The last time we hosted you, in July last year, none of us could have imagined that almost 18 months later, we would still be in the grip of the pandemic."-@DrTedros, media briefing for Geneva-based journalists
"More than 3.3 million people have lost their lives to #COVID19 this year – more deaths than from HIV, malaria and tuberculosis combined in 2020.
And still, COVID-19 continues to claim around 50,000 lives every week."-@DrTedros
"That’s not to mention the unreported deaths, and the millions of excess deaths caused by disruptions to essential health services."-@DrTedros

#COVID19 pandemic has disrupted #malaria services, leading to a marked increase in cases and deaths: 14 million more cases in 2020 compared to 2019, and 69,000 more deaths - new report.

#EndMalaria Image
Approximately 2 in 3 of these additional deaths were linked to disruptions in the provision of #malaria prevention, diagnosis and treatment during the pandemic #EndMalaria
Sub-Saharan Africa continues to carry the heaviest #malaria burden, accounting for about 95% of all malaria cases and 96% of all deaths in 2020.
About 80% of deaths in the region are among children under 5 years of age #EndMalaria Image

These molecules are crucial to maintaining self-tolerance. 👉SIGNALING THROUGH THESE MOLECULES MAY TAKE IMMUNE EFFECT CELLS (ESPECIALLY T CELLS) TO A STATE KNOWN AS "DEPLETION". T cell depletion is defined by reduced effector function, poor memory responses
👉 due to sustained expression of immune checkpoint molecules (such as PD1, # CTLA4, # LAG3 ...). There are numerous types of activating and inhibitory interactions that occur between antigen presenting cells (APC) and T cells and thus regulate the nature of immunity.

#idboardreview can you identify this malarial species? Image
trophozoite of #Plasmodium #ovale #Schuffner’s dots & ovoid shape.
P. ovale #malaria is clinically similar to P. vivax & like P. vivax has a latent phase in liver from which relapse can occur.
Interval to relapse is P.ovale can be months or up to years later.

1) An uninformed, pharisaical condemnation of an industry providing, w/regularity, life-saving, less invasive medical options at huge R&D cost:
2) The tweeter has a campaign against #Pharma, an imperfect industry, as all human endeavors are. She blames Pharma for poor nations, though it has provided millions of free doses. It escapes her that graft often frustrates the administration of those helps. We are blessed...
3) our nation to enjoy market freedoms in which to exercise and profit from our industry and invention. We elect Gov't to hold business accountable and citizens who can organize and sue both. I won't broadbrush a grim picture of an industry that, though imperfectly,...

A child dies from #malaria every two minutes.
One death is one too many.

🚨 Today, WHO recommends RTS,S, a groundbreaking malaria vaccine, to reduce child illness & deaths in areas with moderate and high malaria transmission

Over 800K children have so far received the RTS,S #malaria vaccine & are benefiting from this additional protection against malaria.
The vaccine significantly reduces malaria & life-threatening severe cases and could save tens of thousands of young lives each year.
RTS,S #malaria vaccine was introduced in a pilot programme two years ago.
Since then, more than 2.3 million doses of the vaccine have been administered across Ghana, Kenya and Malawi

@GlobalFund 2021 #ResultsReport: A reader’s guide

#COVID19 is the headline, but there is a lot more to talk about, especially with the #7thReplenishment coming up.…
a 🧵...
#TB is front and center, because it was worst hit by #COVID19. Resources in pulmonary health diverted from TB towards Covid19 – doctors, beds, GeneXpert machines and cartridges – on top of everything else.
#HIV was impacted too, especially #prevention and #testing. #Malaria fared better, probably in part because countries with endemic malaria were hit by #COVID19 latter, though testing did drop.
