Lyme een zeldzame ziekte...

The Lyme wars are upon us. We should probably read up on them

By 2050, 12 percent of the US population will likely be infected by Lyme-causing pathogen

Earth has crossed a scary threshold for the first time inmore than 800,000 years and it could lead to tens of thousands of deaths; May 2018

A plague of ticks and mosquitoes
As the world gets warmer, ticks, mosquitoes, and other disease vectors are expanding their habitats and are able to spread disease for longer before cold weather shuts them down for a season.
We’re already seeing this happen, as a recent CDC report revealed – diseases like Lyme disease, Dengue, and Zika spread by these pests tripled in the US between 2004 and 2016.
We don’t have good ways to control mosquito populations and we’re terrible at stopping ticks. As a result, these conditions, known as vector-borne diseases, are expected to become bigger problems as CO2 cranks up the global thermostat.

Klimaatverandering en impact op de gezondheid;

de toename van via vectoren overgedragen ziektendoor een toenemende verspreiding van hun ziekteverpreiders: teken, muggen, zandvliegen, enz. Veranderingen in de lengte van de seizoenen, de neerslag, de vochtigheid en de temperatuur kunnen de verspreiding en de overlevingskansen van zowel vectoren als ziekteverwekkers vergroten. De klimaatverandering zal dus waarschijnlijk indirect gevolgen hebben voor het bereik van bepaalde vectoren van infectieziekten zoals:

De ziekte van Lyme, die wordt overgedragen door teken. Deze ziekte is momenteel in uitbreiding in onze contreien, in Centraal-Europa en in de Baltische Staten. De klimaatverandering wordt gezien als de hoofdoorzaak voor de verspreiding naar Noord-Europa van een bepaalde tekensoort.
Dengue of knokkelkoorts, een virale ziekte die door muggen overgebracht wordt
Bilharzia of schistosomiasis, waar waterslakjes als tussengastheer optreden
Malaria, door een uitbreiding van het areaal van de muggensoort die deze ziekte verspreidt. Het is mogelijk dat malaria zich ten noorden van de Middellandse zee zal uitbreiden.

Misschien komen er wel meer zuidelijke teken deze kant op, maar Canada vond in Manitoba, waar het weken lang onder de 20 graden is in de winter, teken die besmet waren met Bbsl.en Bbss

Far-Reaching Dispersal of Borrelia burgdorferi Sensu Lato-Infected Blacklegged Ticks by Migratory Songbirds in Canada

Abstract
Lyme disease has been documented in northern areas of Canada, but the source of the etiological bacterium, Borrelia burgdorferi sensu lato (Bbsl) has been in doubt. We collected 87 ticks from 44 songbirds during 2017, and 24 (39%) of 62 nymphs of the blacklegged tick, Ixodes scapularis, were positive for Bbsl. We provide the first report of Bbsl-infected, songbird-transported I. scapularis in Cape Breton, Nova Scotia; Newfoundland and Labrador; north-central Manitoba, and Alberta. Notably, we report the northernmost account of Bbsl-infected ticks parasitizing a bird in Canada. DNA extraction, PCR amplification, and DNA sequencing reveal that these Bbsl amplicons belong to Borrelia burgdorferi sensu stricto (Bbss), which is pathogenic to humans. Based on our findings, health-care providers should be aware that migratory songbirds widely disperse B. burgdorferi-infected I. scapularis in Canada’s North, and local residents do not have to visit an endemic area to contract Lyme disease.

Het is wel de Ixodes scapularis teek.

25-FEB-2019 - De veel te hoge temperaturen voor de tijd van het jaar zorgen er ook voor dat teken actief worden. De komende dagen loopt de tekenactiviteitsverwachting van Tekenradar.nl op tot ‘Hoog’ en zelfs ‘Zeer hoog’ in het zuidelijke deel van het land. Vergeet dus niet een tekencheck te doen na een bezoek aan het groen.

Förster warnen vor Zeckenplage in NRW 24-04-2019;

25 Zecken binnen fünf Minuten

Auch Förster Marco Wesselowsky, zuständig unter anderem für die Wälder in Düsseldorf, Moers und Krefeld, sieht eine klare Entwicklung: Es gibt immer mehr Zecken. 25 Tiere, die innerhalb von fünf Minuten auf eine Hose krabbeln - so sieht seine Bilanz aus.

TICK BOOM Billions of Lyme disease-carrying ticks on the march across England, experts warn
The blood-sucking beasties have bred in the lush vegetation of Kent, Sussex and Essex

A PLAGUE of ticks is on the march across England.
They are booming in the South East where global warming is bringing lush bursts of spring vegetation, experts have found.

Disease-carrying ticks have bred in their billions in rural parts of Kent, Sussex and Essex.
The 'South East Danger Zone' is now as bad as ­traditional danger zones in Italy, Romania, Switzerland and Norway.

It means cases of debilitating Lyme disease are rising, the University of London team says.
Infections shot up by 35 per cent between 2016 and 2017, with around 1,000 every year, according to Public Health England.
The most obvious sign of Lyme disease is a circular red bullseye skin rash surrounding a tick bite, NHS advice says.
Leading UK pest control expert Maio Stanchev said Brits need to be more vigilant, whether at home or abroad.


Ticks could just as easily be lurking in long grass in your garden, just waiting for you to walk past

He said: "You should use a chemical repellent containing DEET to keep the creatures at bay.
"You should also wear light-coloured protective clothing that covers the skin, as well as tucking your trousers into your socks.
"What's also vital is that you check your children and pets for any sign of a bite.
"Don't assume that ticks only live in the forests or wild outdoor areas.
"They could just as easily be lurking in long grass in your garden, just waiting for you to walk past so they can hitch a ride."
The pest control expert said if you find ticks at home, it is important to catch one and place it in a sealed bag or container so doctors can analyse any bacteria.
He added: "Keep the tick for 30 days, just in case you or any members of your family start to experience any of the symptoms of Lyme disease.
"This tick specimen can then be analysed by doctors to either confirm or deny the presence of the bacteria.
"You might also want to return the tick to Public Health England, which has a tick recording and surveillance programme."

What Does Climate Change and Deforestation Mean For Lyme Disease in the 21st Century?

By Laura Jensen

Ecological diseases such as Lyme disease sprout out of the wild and into the human population. As our wildlife lose their homes due to deforestation, they move into concentrated suburban areas, spreading infectious diseases. Climate change worsens these effects. As a society we have to recognize our impact on the environment and wildlife habitat to prevent any further damage.

“The central message behind all of this,” says Dr. Sperber, “is the need to enact laws to protect the environment not only of its intrinsic beauty and wonder but also because we want to protect our health to reverse the course of an epidemic [Lyme Disease] that has been out of control for far too long.”

Te weinig oog voor ziektes door klimaatverandering;

de superteek kan ziektes overbrengen zoals krim-congokoorts. Gelukkig zijn de superteken die momenteel in Nederland zijn gespot daar niet mee besmet. En nog niemand in Nederland is ziek geworden van de beet van de tijgermug, maar het zou wel kúnnen dat besmette insecten zich in Nederland vestigen."
