Disease-bearing mosquitoes reach Crimea and they spread around the world thanks to global warming, scientists warn

  • Two pathogenic mosquitoes can now be found around the Black Sea coast
  • They can be identified by the distinctive signs on their body and legs
  • Russian experts have warned about the development of epidemics in Crimea
  • In the northeast, in Penza, an outbreak of haemorrhagic fever has been reported

Disease-bearing mosquitoes have reached the Crimea peninsula in southern Russia because global warming promotes the spread of potentially deadly insects.

An outbreak of haemorrhagic fever with renal syndrome – usually & # 39; mouse fever & # 39; – has also erupted in the Penza area northeast of the Black Sea.

News.ru reported outbreaks in 13 districts, with 161 fever patients in the region diagnosed so far this year.

Mosquitoes are also well-known vectors for various deadly diseases, including Zika, the chikungunya virus, dengue fever, the West Nile virus and yellow fever.

Russian epidemiologists have warned that further outbreaks run the risk of spreading and spreading further north in Russia.

Disease-bearing mosquitoes have reached the Crimea peninsula in southern Russia because global warming promotes the spread of potentially deadly insects

The disease-bearing mosquito species Aedes aegypti and Aedes albopictus are believed to have arrived in the Black Sea area – along whose entire coastline they can now be found – from Egypt and Southeast Asia.

In addition to viruses, mosquitoes can also spread worm larvae that can seriously endanger the internal organs of both affected animals and humans.

Russian disease experts have warned that an epidemic in Crimea could easily break out and spread to central Russia, the newspaper Izvestia reported.

The risk is increased by the potential for tourists and other travelers to transport the disease over longer distances that it might otherwise spread.

& # 39; Migrants of tropical diseases, which must not occur in the north, migrate to areas with suitable temperature conditions, & # 39; told the Moscow-Martsinovsky Institute of Medical Parasitology and Tropical Medicine biologist Alexander Lukashev, Crime Russia.

& # 39; In Russia they have already multiplied in the south and are now moving to Central Russia. & # 39;

Professor Lukashev said that disease-bearing mosquitoes can easily be distinguished from mosquitoes that are native to Russia.

The disease carriers either have white spots on their legs and a matching strip on their back, or else black and white striped legs and a spotted belly.

However, Russian officials have reportedly attempted to reject the full extent of the danger of these newcomers.

President Vladimir Putin has admitted that Russia is increasingly feeling the impact of climate change, but has denied that the phenomena of origin were caused by humans.

Unusually warm conditions and floods at the end of May last year were attributed to the cause of a mosquito plague that affected the Voronezh region in southwestern Russia, which is only 290 miles from the capital Moscow.

Previously, only yellow fever and West Nile fever were previously registered in Russia, the Times reported.

Yellow fever was eliminated previously in the 1950s, but has recently re-emerged.

It is believed that the disease-bearing mosquito species Aedes aegypti and Aedes albopictus probably arrived in Crimea and around the Black Sea - along whose entire coastline they can now be found - from Egypt and Southeast Asia

WHY MOSQUITO & BOTH SOME PEOPLE AND NOT OTHERS?

About 20 percent of people are more prone to mosquito bites.

And although scientists don't have to find a cure yet, they have some ideas about why the insects attack some of us more than others.

Blood type

Certain blood groups are more attractive to taste buds of mosquitoes.

Research has shown that people with Type O blood – the most common blood type – tend to be bitten twice as much as people with Type A. People with Type B blood are bitten somewhere in the middle.

Exercise and metabolism

Sweating while exercising can also make a person more susceptible to a mosquito bite.

Powerful exercise causes higher body temperatures and an accumulation of lactic acid, which sends tasty signals to the insects.

Beer

A cold glass of beer makes you sweat and your body releases ethanol, which may be the reason why mosquitoes like to land on beer drinkers.

Skin bacteria

Levels of bacteria on human skin can cause mosquitoes to bite, especially where bacteria clusters such as on the ankles and feet.

However, different types of bacteria on the skin tend to eliminate the insects.

Body odor

Mosquitoes use even the weakest body odors when searching for potential victims.

It has been known for some time that female mosquitoes use specific sensors around their mouths to detect carbon dioxide exhaled by humans and animals.

But a few years ago, researchers at the University of California Riverside discovered that the blood-sucking insects also use these sensors to detect body odor – especially the odor of feet.
