The COVID-19 pandemic has fundamentally altered the physiological landscape of individuals around the globe. The virus has demonstrated its ability to traverse various bodily functions, leaving a trail of physiological changes in its wake. From the intricate dynamics of the immune response to cardiovascular issues, COVID-19 has brought about unprecedented impacts on human health in various ways.

But what are the correlations, if any, between COVID-19 and an increase in stroke incidences especially amongst the young? In light of the increasing number of cases of COVID-19 in Malaysia again, we attempt to investigate the links.

THE LINK TO STROKE

Traditionally, when we speak about strokes, it tends to be an “elderly persons” disease, a health concern prevalent amongst those aged 50 and above.

However, over the past 3 years since the first outbreak of COVID-19 pandemic, a worrying connection has emerged between the virus and incidences of strokes in younger individuals.

COVID-19 is associated with a higher risk of stroke, a majority of them being ischaemic strokes caused by a blockage in an artery that supplies blood to the brain.

A study suggested a connection between the high prevalence of vascular risk factors and concurrent elevation of proinflammatory and procoagulation biomarkers in this.

In the same study, it has been proposed that the virus that causes COVID-19 infects the cells that line the inside of the blood vessels.

These infected cells release several pro-inflammatory factors that attract other immune cells to the affected area.

In turn, this leads to damage to the lining cells, activating platelets and other factors involved in clotting.

This chain of events eventually increases the risk of a blood clot that could potentially travel up to the brain and cause a stroke.

Hypercoagulability and inflammatory response cause vascular complications, increasing the risk of strokes, regardless of age.

Findings from another large-scale study suggested that COVID-19 is a risk factor for deep vein thrombosis, pulmonary embolism, and bleeding.

The risk of developing blood clots in the lungs and legs is significantly elevated for up to 6 months upon contracting COVID-19.

After the initial 30 days of infection, individuals afflicted with COVID-19 displayed heightened susceptibilities and endured a year-long burden of newly emerging cardiovascular conditions.

These conditions range from cerebrovascular issues and dysrhythmias to inflammatory heart disease, ischaemic heart disease, heart failure, thromboembolic disease, and assorted cardiac disorders.

Strikingly, these risks manifested consistently across various demographic factors, such as age, race, and gender, as well as other established cardiovascular risk factors like obesity, hypertension, diabetes, chronic kidney disease, and hyperlipidemia.

Notably, even those without any pre-existing cardiovascular conditions prior to exposure to COVID-19 exhibited these risks, suggesting a propensity for these complications to manifest in individuals traditionally considered at low risk for cardiovascular diseases.

IN SUMMARY

The data and evidence gathered do point to a heightened risk of stroke brought about by COVID-19, regardless of age.

Even though it remains an uncommon occurrence, it remains a risk especially for individuals pre-existing health conditions that are known to boost the risk of stroke.

While the correlation between incidences of stroke, COVID-19 and how it affects younger individuals remains a subject of ongoing research and study, it remains crucial in recognizing the potential risks and taking appropriate and proactive measures.

Michelle Yeoh Joins Local Healthcare NGOs in Rallying Malaysians Against COVID-19

WORDS LIM TECK CHOON

On 17 August 2023, the Malaysian Society of Infection Control and Infectious Disease (MyICID), the National Cancer Society of Malaysia (NCSM), and the Malaysian Red Crescent (MRCS), in collaboration with Pfizer Malaysia, launched the MyPELINDUNG campaign.

WHAT’S MyPELINDUNG?

It’s a public educational campaign aimed at mitigating the threat of COVID-19 in Malaysia by increasing the awareness levels of Malaysians on the importance of up-to-date vaccination and seeking of prompt COVID-19-specific treatment.

Among the luminaries gracing the launch were:

  • Her Highness Dato’ Seri DiRaja Tan Sri Tunku Puteri Intan Safinaz binti Almarhum Sultan Abdul Halim Mu’adzam Shah, Tunku Temenggong Kedah, who is the National Chairperson of the Malaysian Red Crescent
  • Datuk Dr Norhayati Rusli, Deputy Director-General of Public Health, Ministry of Health
  • Yang Berbahagia Tan Sri Dato’ Seri Michelle Yeoh, Oscar-winning actress
  • Dr Shaharudeen Bin Kamaludeen, the President of MyICID
  • Dato Dr. Saunthari Somasundaram, the President of NCSM
  • Professor Datuk Dr Zulkifli Ismail, the Chairman of Immunise4Life
  • Madam Luksanawan Thangpaibool, the Country Cluster Lead of Pfizer Malaysia, Pakistan and Brunei
A PRINCESS’S WORD OF WISDOM

“Just as it takes many drops to form an ocean, our shared actions—however small they may seem —can create significant impact in the fight against COVID-19,” says Yang Teramat Mulia Dato’ Seri Diraja Tan Sri Tunku Puteri Intan Safinaz.

She adds: “It’s through initiatives like MyPELINDUNG that we can harness our collective strength to navigate this health issue. Together, with the strength of unity and shared responsibility, we can contribute to a healthier, safer nation for all Malaysians.”

WAIT, ISN’T COVID-19 OLD NEWS?

Not so! Yes, Malaysia has made significant strides but the virus responsible for COVID-19 continues to circulate in our communities and can still lead to hospitalizations and even death, especially among high-risk groups.

Hence, the experts driving MyPELINDUNG advocates constant vigilance, updating of COVID-19 vaccinations, adherence to recommended health measures, and prompt seeking of COVID-19-specific treatment if one is tested positive.

VACCINATION IS KEY, EXPERTS SAY

MyPELINDUNG aims to reduce public hesitancy around the COVID-19 booster doses by disseminating scientifically-accurate information and addressing common concerns held by Malaysians about these boosters.

The campaign’s efforts will particularly focus on high-risk groups, as up-to-date vaccination (including booster doses) can reduce their risk of severe illness, hospitalization, and death.

Dr Shaharudeen Kamaludeen, President of MyICID, tells us: “It’s paramount that we understand the critical role vaccinations play in mitigating the severity of COVID-19. Vaccinations, including recommended booster doses, are our primary line of defence against this virus.

He also adds that prompt medical consultation and treatment after a positive test for COVID-19 are equally vital.

Professor Datuk Dr Zulkifli Ismail, the Chairman of Immunise4Life, further emphasizes the importance of maintaining one’s up-to-date vaccination status.

“Full vaccination significantly reduces the risk of severe disease outcomes,” he says. “We urge everyone, particularly those in high-risk groups, to consider vaccinations as their personal shield against the virus, and to remember that this shield is most robust when all recommended doses, including boosters, have been administered.”

THE ACTRESS ADVOCATES

Tan Sri Dato’ Seri Michelle Yeoh concurs with the experts, adding that she herself had 2 brushes with the COVID-19 vaccine.

She participated in an educational video for MyPELINDUNG, a video that she is very proud of, and will continue to commit to encouraging Malaysians to remain vigilant and take the appropriate protective steps against COVID-19.

“Trust the science,” she urges.

PROMPT & QUICK TREATMENT CAN SAVE LIVES

“The most important thing to remember about treatment for COVID-19 is that it should be started as soon as possible after diagnosis to be effective,” states Dato Dr Saunthari Somasundram. “If you test positive for COVID-19, treatments are available that can reduce the likelihood of severe illness, hospitalization, and death. Please don’t delay because COVID-19 specific treatment must be started within days after you first develop symptoms to be effective.”

Tan Sri Michelle Yeoh concurs. “On screen, I’ve navigated flying stunts and leapt off moving vehicles, but life isn’t an action film, and we can’t afford to wait for the dramatic last-minute rescue. If you’re showing any symptoms, act fast, seek help at once.”

Expert Coalition to Educate Malaysians & Prevent Another COVID-19 Surge

PRESS RELEASE
COVID-19 IS STILL A THREAT

As we welcomed 2023, China reported a huge spike in daily COVID-19 cases during the end of year holiday seasons 2022.

After a period of pandemic fatigue and indifference, the event sparked sudden and short-lived fear and caution among the global as well as Malaysian community.

The news triggered some Malaysians to be up in arms, calling for a ban on travelers from China and reinforcement of pandemic SOPs such as the mandatory wearing of mask in public areas.

Nonetheless, the interest soon died down as other headlines made their way in the news.

It appears that it is only when crises are about to hit our shores that we react.

In fact, as highlighted by the World Health Organisation (WHO), we need to always be prepared and cannot afford to be reactive.

On January 27, 2023, it announced and reminded member countries that COVID-19 remains a public health emergency of international concern.

WHO compared 28-days data between Dec 5, 2022 to Jan 1, 2023 and Jan 2 to Jan 29, 2023.

It found that although the number of cases reported decreased by 78%, the number of deaths increased steeply by 65%.

This result is mainly due to the large wave of cases and deaths in the Western Pacific Region, especially in China.

WHO further states that the numbers may be an underestimation due to the reduction in testing and delay in reporting in many countries.

STAY VIGILANT & PROTECT THE VULNERABLE

3 years into the pandemic, Malaysia has reported more than 5 million cases and over 36,000 deaths.

In 2021, it became the main cause of death in Malaysia, overtaking heart disease.

The risk of death is higher among:

  • Those above 60 years
  • Individuals with underlying health conditions
  • Unvaccinated individuals

According to MOH data between Jan 1, 2022 to July 31, 2022, 75% of COVID-19 deaths were among individuals 60 years and above, and 86% of deaths were among those with at least one underlying health condition .

Compared to the first year of pandemic, we are now more prepared to curb COVID-19 due to advancement in preventive measures, rapid diagnoses, and management tools such as vaccination, rapid test kits (RTK) as well as early treatment with antivirals.

These tools are important particularly to prevent severe COVID-19, keeping individuals especially those with risk factors away from hospitalization, intensive care unit (ICU) admissions and ultimately death.

Nonetheless, these tools will only be useful if they are being utilized optimally.

While Malaysians were quick on the uptake of primary COVID-19 vaccination doses, the uptake of booster doses are very poor with only 49.7% uptake of the 1st booster and a mere 1.6% of the 2nd booster (as of Feb 7, 2023) .

While no concrete data is available, there are good reasons to believe that due to pandemic fatigue, people are now less likely to test and seek treatment for COVID-19.

It is also important to note that antiviral treatment needs to be taken within the first 5 days of symptom onset. Thus, speed is of the essence.

We cannot risk another surge of COVID-19 globally or locally as it would put a toll on our healthcare system and risk overwhelming it.

In addition to COVID-19, we are also facing the threat of other respiratory illnesses such as influenza and respiratory syncytial virus (RSV).

As it stands, we are currently experiencing overcrowding in Emergency Departments.

Hence, it is crucial that we answer the calls of WHO and the Ministry of Health Malaysia to continue urging the public especially those who are in the high-risk groups (older persons, individuals with underlying medical conditions) to take precautions against COVID-19.

OUR CAMPAIGN

The Malaysian Society of Infection Control and Infectious Diseases (MyICID) in collaboration with the Family Medicine Association Malaysia (FMSA) and Malaysian Medical Association (MMA) are organising an educational campaign themed COVID-19: QUICKLY TEST & TREAT.

Our objectives

This campaign aims to urge the public especially individuals who are at high-risk as well as their family members to continue protecting themselves and others from severe COVID-19 by:

  • Getting primary and booster doses
  • Testing immediately upon onset of symptoms
  • Seeking early treatment, within the first five days of symptoms

Recently, our Ministry of Health detected SARS-CoV-2, the virus responsible for COVID-19, during wastewater surveillance at airports in the country. It was also reported that China has begun SARS-CoV-2 wastewater surveillance for selected cities after the cessation of the country’s zero COVID policy.

WASTEWATER SURVEILLANCE EXPLAINED

In wastewater surveillance, samples of untreated sewage from selected communities and institutions are routinely collected and sent to laboratories for identification and quantification of virus content and testing for different or new virus variants.

Benefits of wastewater surveillance
  • It provides a rapid real-time ‘snapshot’ of the disease prevalence in the community where the wastewater was sampled from.
  • Wastewater surveillance also addresses challenges of disease under-reporting due to asymptomatic infections, self-home treatment, and delayed or absent notifications from medical practitioners.
  • Information from wastewater surveillance can be used to monitor disease burden patterns, reintroduction or emergence of a new pathogen/variant, and even evaluate the impact of community behavioural campaigns such as masking and physical distancing.

An example of the importance of wastewater surveillance is the detection, in 2022, of wild polio virus in sewage samples during routine testing in London and New York before any clinical cases were reported. This prompted the local health authorities to implement immediate measures to enhance the coverage of primary polio vaccination together with polio boosters in at-risk communities.

Limitations of wastewater surveillance

However, wastewater surveillance cannot replace the existing disease notification system and clinical testing as the wastewater comes from pooled community sewage samples and cannot be used for individual diagnosis.

Apart from this, technical and logistic challenges can also affect the accuracy of the results of wastewater surveillance.

Nonetheless, the information from an effective wastewater surveillance system can greatly complement existing notification system, as it provides an early warning alert for local health authorities to implement prompt targeted interventions in the communities at risk.

WASTEWATER SURVEILLANCE & COVID-19 DETECTION

Since the emergence of the COVID-19 pandemic in 2020, there has been ongoing research into the transmission dynamics and ways to curb the disease spread.

It is known that the SARS-CoV-2 virus spreads mainly through oral and nasal secretions. However, the virus is also shed in stools for prolonged periods of time. Individuals infected with the virus can shed the virus in their stools, irrespective of whether they have symptoms of COVID-19.

Wastewater surveillance has been implemented in many countries as an environmental monitoring tool to rapidly detect the presence of the SARS-CoV-2 virus in a community and enable local health authorities to be aware of the transmission risk factors, emergence of new variants, and the impact of community preventive measures.

Hong Kong

Hong Kong detected the delta variant in the sewage samples since the end of December 2020 and strengthened public health interventions by informing the public about the common symptoms, and the importance of continuing physical distancing and masking, in addition to hand hygiene and respiratory etiquette.

United States

In July 2022, California researchers reported that sampling of community wastewater in San Diego detected the presence of the alpha, delta, epsilon, and omicron COVID-19 variants up to 14 days before they started appearing on nasal swabs. This implies that wastewater surveillance applied to transportation-based sanitation systems can serve as an early indicator of possible community transmission.

SO, SHOULD WE BE WORRIED ABOUT COVID-19 IN OUR WASTEWATER?

The general public need not be alarmed by the news regarding the detection of the SARS-CoV-2 virus in human waste.

As COVID-19 has now become endemic across most countries around the world, the detection of the SARS-CoV-2 virus in sewage samples is not an unusual finding.

From the Ministry of Health’s initial reports, the variants isolated are already in circulation in Malaysia and the risk posed to human health and the environment is minimal.

However, being aware of such a system enables all of us to be better receptive of updated information shared by the Ministry of Health from time to time.

IT CAN BE CHALLENGING FOR A PARENT TO DETERMINE FACTS FROM FICTION WHEN IT COMES TO NEWS ON SOCIAL MEDIA

Netizens who are vaccine hesitant have an alarming footprint on social media. In a vicious cycle, their hesitance is likely to be fueled by health (mis)information obtained from a variety of sources, including news media such as the Internet and social media platforms.

As access to technology has improved, social media has attained global penetration. In contrast to traditional media, social media allow individuals to rapidly create and share content globally without editorial oversight. Users may self-select content streams, contributing to ideological isolation. As such, there are considerable public health concerns.

These worries may be magnified in the face of the ongoing COVID-19 pandemic. As the development and subsequent deployment of more vaccines are expected to play a critical role in downstream emerging pandemic control efforts, social media will remain a powerful tool. Most concerning is how (mis)information and (un)substantiated reports on its platforms will threaten to erode public confidence even well before the release of any scientific evidence.

It is not readily evident why social media is so disproportionately successful in promoting vaccine hesitancy as opposed to uptake. Social media users may represent a skewed population sample with baseline misperceptions regarding the benefits and side effects of vaccination whilst simultaneously lacking familiarity with the consequences of vaccine-preventable disease. Moreover, when evaluating the risks and benefits of vaccination in general, the risks may be overestimated and may seem more immediate, and tangible as compared to the more abstract potential benefits of disease prevention.
