Mosquitos and man, a lethal cycle at work since the dawn of time



It begins and ends with a hungry mosquito, settling on human skin to suck up its fill of blood and unwittingly completing the life cycle of a parasite that, in one of nature's quirkiest three-way relationships, depends upon both insect and human being for its existence.

And not just any mosquito: the carrier - or "vector" - is always an Anopheles mosquito - or, at least, one of the 20 out of the 380 species of Anopheles mosquitoes capable of transmitting malaria. Male mosquitoes do not feed on blood; it is always a female, and usually between dusk and dawn. These are the vampires of the insect world.

The disease we call malaria (an 18th-century contraction of the Italian for "bad air"; marsh gases were originally blamed for causing the disease) - exists in a vicious cycle in which both human and mosquito play their parts as hosts, but in which only humans pay for the privilege with their lives. The mosquito takes in cells of the Plasmodium parasite from an infected human, fertilises them in its gut and returns the resultant spores to another human being via its salivary gland.

This relationship, say experts at the Department of Microbiology and Immunology at the University of Leicester in England, has been going on "since the dawn of time". The parasites probably originated in Africa, along with man, and mosquito fossils have been found dating back 30 million years. In another one of nature's quirks, "the Plasmodium parasites are highly specific, with man as the only vertebrate host and Anopheles mosquitoes as the vectors. This specificity of the parasites also points towards a long and adaptive relationship with our species".

There are four species of Plasmodium; one of the most common, and the most deadly, is falciparum, common throughout the World Health Organization's Eastern Mediterranean region, which includes Arabia, Iraq and Iran.

In the human host, the parasites head for the liver, where they multiply and infect red blood cells, so threatening the blood supply to vital organs. According to the WHO, symptoms might not appear for 10 to 15 days, when the victim may start to experience headaches, fevers and vomiting - symptoms often mistaken at first for flu - and, "if not treated within 24 hours, P. falciparum malaria can progress to severe illness often leading to death".

Caught sufficiently early, malaria can be treated with a number of different drugs but, says the WHO, because the parasites quickly develop resistance, the best solutions are personal protection - such as prophylactic antimalarial tablets and sleeping nets - and "vector control", chiefly, the elimination of mosquito breeding grounds, such as pools of stagnant water, and the use of insecticides.

Cryopreservation: A timeline

  2. Ovarian tissue surgically removed
  3. Tissue processed in a high-tech facility
  4. Tissue re-implanted at a time of the patient’s choosing
  5. Full hormone production regained within 4-6 months

The more serious side of specialty coffee

While the taste of beans and freshness of roast is paramount to the specialty coffee scene, so is sustainability and workers’ rights.

The bulk of genuine specialty coffee companies aim to improve on these elements in every stage of production via direct relationships with farmers. For instance, Mokha 1450 on Al Wasl Road strives to work predominantly with women-owned and -operated coffee organisations, including female farmers in the Sabree mountains of Yemen.

Because, as the boutique’s owner, Garfield Kerr, points out: “women represent over 90 per cent of the coffee value chain, but are woefully underrepresented in less than 10 per cent of ownership and management throughout the global coffee industry.”

One of the UAE’s largest suppliers of green (meaning not-yet-roasted) beans, Raw Coffee, is a founding member of the Partnership of Gender Equity, which aims to empower female coffee farmers and harvesters.

Also, globally, many companies have found the perfect way to recycle old coffee grounds: they create the perfect fertile soil in which to grow mushrooms.

Emiratisation at work

Emiratisation was introduced in the UAE more than 10 years ago

It aims to boost the number of citizens in the workforce particularly in the private sector.

Growing the number of Emiratis in the workplace will help the UAE reduce dependence on overseas workers

The Cabinet in December last year, approved a national fund for Emirati jobseekers and guaranteed citizens working in the private sector a comparable pension

President Sheikh Khalifa has described Emiratisation as “a true measure for success”.

During the UAE’s 48th National Day, Sheikh Khalifa named education, entrepreneurship, Emiratisation and space travel among cornerstones of national development

More than 80 per cent of Emiratis work in the federal or local government as per 2017 statistics

The Emiratisation programme includes the creation of 20,000 new jobs for UAE citizens

UAE citizens will be given priority in managerial positions in the government sphere

The purpose is to raise the contribution of UAE nationals in the job market and create a diverse workforce of citizens

Dr Afridi's warning signs of digital addiction

Spending an excessive amount of time on the phone.

Neglecting personal, social, or academic responsibilities.

Losing interest in other activities or hobbies that were once enjoyed.

Having withdrawal symptoms like feeling anxious, restless, or upset when the technology is not available.

Experiencing sleep disturbances or changes in sleep patterns.

What are the guidelines?

Under 18 months: Avoid screen time altogether, except for video chatting with family.

Aged 18-24 months: If screens are introduced, it should be high-quality content watched with a caregiver to help the child understand what they are seeing.

Aged 2-5 years: Limit to one-hour per day of high-quality programming, with co-viewing whenever possible.

Aged 6-12 years: Set consistent limits on screen time to ensure it does not interfere with sleep, physical activity, or social interactions.

Teenagers: Encourage a balanced approach – screens should not replace sleep, exercise, or face-to-face socialisation.
