Amid the ongoing Covid-19 scare in the UK, in another news, two species of disease-carrying mosquito have been also found there. These two species are now being found as a result of climate change, scientists too have warned against the same.

Aedes aegypti, also known as the Egyptian mosquito, and Aedes albopictus, also known as the (Asian) tiger or forest mosquito, both known for carrying diseases like yellow fever, dengue, chikungunya, Zika and dirofilariasis have been detected in surveillance traps set by the UK Health Security Agency (UKHSA). This was revealed in the UKHSA peer-reviewd study on invasive mosquito surveillance.

The Egyptian mosquito eggs were detected in a freight storage facility near London's Heathrow Airport, in September 2023- and tiger mosquitoes were detcted in August 2024. This will be the first time that the tiger mosquitoes have been detected since 2019, at a motorway srvice station in Kent.

The study published in research journal PLOS Global Public Health, reported the findings were lead by UKHSA and the Centre for Climate and Health Security.

What Has Changed Now?

Historically, both these species were limited to subtropical and tropical regions, however, among the populations established in southerns and central Europe, the mosquitoes have shown its ability to survive in temperate climates.

Rising temperature is said to be one of the major reasons for incursion of invasive species. This has put new populations at risk of disease transmission.

The authors of the study said, "While there is currently no evidence that Ae. albopictus or Ae. aegypti are widely established in the UK, without timely action, the UK faces the risk of invasive mosquito populations becoming established... proactive measures enhance resilience against emerging vector borne disease risks."

Call To Action

In addition to monitoring at ports and transport hubs across England, Wales and Northern Ireland, the UKHSA has also set up traps in the Kent marshes—considered an ideal spot for mosquitoes to settle due to its warm, wet conditions.

The UKHSA has also run Mosquito Recoding Scheme (MRS). This is a citizen-science project that receives and identifies mosquitoes submitted by members of public, including in response to nuisance biting incidents. Between 2005 and 2021, 286 reports of mosquitoes were submitted to the MRS, all of which were native UK species.

The aim of the scheme is to detect unusual or invasive species of mosquito, so prevention tactics could be put to use.

Collin Johnson, the lead author of the study and a senior medical entomologist at the UKHSA, said for the 2023 and 2024 discoveries: "Each detection triggered enhanced local surveillance and control measures, and the fact that no further specimens were found suggests these were isolated incursions."

"The collaborative efforts between UKHSA, local authorities and landowners were key to rapidly mobilising and preventing the establishment of invasive mosquitoes," he said.

More than 90 passengers and crew aboard a Royal Caribbean cruise ship have fallen ill from Norovirus, as per the reports. This ship's final stop was Miami.

The outbreak on the Royal Caribbean was first reported to the US Centers for Disease Control and Prevention (CDC). The ship had departed San Diego on September 19. A total of 94 passenger and 4 crew members were "reported being ill during the voyage," noted the CDC. The main symptoms as per CDC was diarrhea and vomiting.

Other symptoms include muscle ach, abdominal pain, fever, or three or more loose sttols within 24-hour period. From a total of 1,874 passengers and 833 crew, as per the reports, only 4% of people on board were infected, confirmed CDC.

The crew on the ship has increased their cleaning and disinfecting procedures. Stool specimens from gasteointestinal illness have been collected for testing and have been isolated from those who are sick.

In a statement to USA TODAY, the Royal Caribbean said, "The health and safety of our guests, crew, and the communities we visit are our top priority. To maintain an environment that supports the highest levels of health and safety onboard our ships, we implement rigorous cleaning procedures, many of which far exceed public health guidelines."

The Independent reports that the cruise ship also consulted with the Vessel Sanitation Program (VSP), which is remotely monitoring the situation, including review of the outbreak, response, and sanitation procedures.

What Is Norovirus?

As per the CDC, it is a very contagious virus that causes vomiting and diarrhea. It is commonly called the 'stomach flu" or "stomach bug".

However, norovirus illness is not related to the flu. The flu is caused by the influenza virus. Norovirus causes acute gastroenteritis, an inflammation of the stomach or intestines.

Most people with norovirus illness get better within 1 to 3 days; but they can still spread the virus for a few days after.

What Are The Symptoms Of Norovirus?

• Diarrhea
• Vomiting
• Nausea
• Stomach pain
• Fever
• Headache
• Body aches
• Dehydration: If you have Norovirus, you can feel extremely ill and dehydrated and the symptoms can show through decreased urination, dry mouth and throat, feeling dizzy when standing up, crying with few or no tears, unusual sleepiness or fussiness.

Who Is At Risk?

• Anyone can get infected and sick with norovirus.
• People of all ages are affected during norovirus outbreaks.
• Genetic factors can partly determine your likelihood of infection.
• Raw oysters and other filter-feeding shellfish may contain viruses and bacteria that cause illness or even death.
• Eating raw shellfish puts anyone at risk of contracting norovirus.
• Children under 5, older adults, and people with weakened immune systems are more likely to develop severe infections.

The US government shuts down at midnight confirmed Associated Press. The Vice President JD Vance said, "I think we're headed to a shutdown because the Democrats won't do the right thing," after a meeting where Congressional Democrats refused to give Republicans the votes they needed to pass a short-term funding agreement. The Democrats have demanded overhauls to Medicaid cuts and extensions to health care tax credits, something Republicans wish to stay out of.

House Minority Leader Hakeem Jeffries said that Republicans are "divorced from reality". He said, "They just wanted to kick the health care problem down the road."

What Does US Government Shutdown Mean For Health Services?

During a shutdown, only 59% of employees would be working at the Department of Health and Human Services. The rest are to be furloughed, meaning to be discharged from their job.

This means, out of the 47,257 employees who would be kept during the shutdown, only 35,000 would be continued to paid, while 12,000 would work without pay. Around 32,460 Health and Human Services (HHS) employees will be discharged from their work.

For the Centers for Disease Control and Prevention (CDC), only 36% of employees would work, with 15% without pay, also reported by ABC News. At the Food and Drug Administration (FDA), 86% employees would continue to work, with 19% without pay.

What it means for safety guidelines? The FDA's Animal Drugs and Foods Program "would end pre-market safety reviews of novel animal food ingredients for livestock, thus be unable to ensure that the meat, milk, and eggs of livestock are safe for people to eat; activities would be limited to those that address imminent threats to the safety of human life".

The National Institutes of Health would also come down to 24% of employees.

Will Medicare and Medicaid Continue During The US Government Shutdown?

Federal spending's biggest portion which is considered 'mandatory' will remain untouched, including payments by Social Security, Medicare and Medicaid.

While government officials say that payments won't be affected, related services could, however, slow down, including receiving replacement cards and benefit verification services.

This could also threaten around 7 million low-income women and their children who relied on programs like the Women, Infants. and Children (WIC), a US federal program that provides nutritious foods, nutrition education, and referrals to healthcare and social services for low-income pregnant and postpartum women, infants, and children up to the age of 5, who are at nutritional risk.

Ali Hard, who is the policy director for the National WIC Association told ABC News that if a shutdown continues for more than a week, WIC may begin to run out of funds.

Why Is The US Government Shutting Down?

The main crux of it could be the disagreement in the health policies. For the extended funding, which would only be possible through cuts in Medicaid, the Senate voted 55-45 on the measure, which has left Republicans five votes short of 60 vote threshold.

President Donald Trump on this said, "They (Democrats) want to give health care to illegal immigrants, which will destroy health care for everybody else in our country."

Previously it happened during the 2018-2019 shutdown, which lasted for 35 days.

Every year on October 1, International Day of Older Persons is observed so as to raise awareness about the challenges and opportunities of ageing. The World Health Organization (WHO) notes that it is a day for honoring the contribution of older persons to society and also highlighting the importance of their dignity, independence, and inclusion.

International Day of Older Persons 2025 Theme

This year's theme advocates for healthy and inclusive aging. The United Nations (UN) Secretary-General Antonio Guterres says, "This year's theme reminds us, older persons are powerful agents of change. Their voices must be heard in shaping policies, ending age discrimination, and building inclusive societies."

UN notes that this year's theme is: Older Persons Driving Local and Global Action: Out Aspirations, Our Well Being and Our Rights.

Importance And Significance of International Day Of Older Persons

WHO notes that by 2100, the number of people aged 65 and over would reach 2.4 billion, and the fastest growing segment will be those aged 80 and older. Much of the work at the WHO Kobe Centre aims to accelerate progress toward universal health coverage (UHC) in the context of population ageing to improve the accessibility, affordability and acceptability of health services including long-term care (LTC) for older people.

Over the past year, new research was undertaken to examine unmet health and social care needs among older adults (generally above 60 years) across five of WHO’s regions. The aim was to ensure that this population is not excluded from global progress towards universal health coverage (UHC).

For the first time, policymakers have access to region-specific evidence highlighting the gaps and opportunities in care, enabling them to address barriers that lead to unmet needs. Strengthening health information systems in this way is considered vital for inclusive planning and for improving health outcomes and wellbeing among older people.

How health services are financed also plays a critical role in ensuring coverage, quality, financial protection, and overall outcomes for older populations.

Origin of International Day For Older Persons

It was on December 14, 1990, when the UN General Assembly designated October 1 as the International Day for Older Persons, under the resolution 45/106. This was preceded by initiatives such as the Vienna International Plan of Action on Ageing, which was adopted by the 1982 World Assembly on Ageing and endorsed later that year by the UN General Assembly.

In 1991, the General Assembly adopted the United Nations Principles for Older Persons (resolution 46/91). In 2002, the Second World Assembly on Ageing adopted the Madrid International Plan of Action on Ageing, to respond to the opportunities and challenges of population ageing in the 21st century and to promote the development of a society for all ages.

The number of older people (defined as those aged 65 years or older) tripled from around 260 million in 1980 to 761 million in 2021. Between 2021 and 2050, the global share of the older population is projected to increase from less than 10% to around 17%. Rapid growth in the number of people reaching older ages underscores the significance of promoting health, preventing, and treating illnesses throughout the entire course of life.
