Keeping the virus at bay

The monsoon season may bring an increase in influenza cases, even in tropical Malaysia. Get vaccinated to avoid contracting the highly contagious virus, say health experts. Business operators, meanwhile, want a safe workplace and to allow flexible options for their staff.

GEORGE TOWN: While the influenza virus tends to thrive during the colder months in countries with four seasons, tropical nations like Malaysia could still face a potential outbreak, says a virologist with Universiti Sains Malaysia (USM).

“Increased rainfall towards the end of the year, particularly in several states across Malaysia recently, often correlates with a rise in influenza cases,” said Dr Kumitaa Theva Das.

With the influenza virus constantly evolving, she noted that medical experts have recommended annual vaccinations to protect against the latest virus strains.

The World Health Organization (WHO) recommends people take the flu jab once every year, in February for those living in the Northern Hemisphere and in September for people in the Southern Hemisphere.

Dr Kumitaa said a common misconception is that influenza, often referred to as the “flu”, is no different from the common cold.

“In reality, influenza is a far more severe respiratory infection that can be life-threatening, especially for the high-risk groups.

“While cold symptoms are usually mild, influenza presents with more intense symptoms, including fever, severe muscle aches and extreme fatigue.

“In some serious cases, individuals may even experience chest pain, shortness of breath and loss of consciousness,” said Dr Kumitaa.

The Institute for Research in Molecular Medicine (Informm) senior lecturer added that some people are particularly susceptible to contracting influenza.

Young children, the elderly, pregnant women, people with chronic health conditions and those with weakened immune systems are all considered to be in the high-risk group, she noted.

“Because their immune systems are either still developing or less resilient, these individuals are at a higher risk of experiencing severe complications from the virus,” she explained.

She also said that influenza is highly contagious, especially during the initial stages when the symptoms begin to show.

An infected person can spread the virus through droplets released when they cough or sneeze, making close-contact environments such as schools and public transportation a prime setting for transmission, she added.

Public health specialist Prof Dr Sharifa Ezat Wan Puteh said influenza could cause pneumonia, adding that pneumonia is one of the leading causes of deaths in the country, especially among women and the elderly.

“Hence vaccinations against influenza are very important, especially among the high-risk groups such as the elderly, young children, disabled, homeless and immune-compromised people like diabetics and cancer patients.

“It could be dangerous for those in the high-risk categories because it could lead to lung complications,” she said.

Dr Sharifa Ezat also urged the government to increase allocations for flu vaccinations, given that they may be costly for the low-income groups.

USM family medicine specialist Dr Mastura Mohd Sopian said certain groups of people, including health workers and infants younger than six months, are at greater risk of developing severe symptoms and complications.

She, too, reminded the public that vaccination is one of the most effective measures against influenza.

There are other simple practices that can help reduce the risk of infection.

“Wash your hands frequently with soap and water to reduce the chance of infection.

“Avoid touching your eyes, nose and mouth as the virus can enter the body through these areas.

“Wear a mask in crowded places or if you are experiencing symptoms. Try to limit contact with individuals who are symptomatic to minimise exposure,” advised Dr Mastura.

Beware the influenza bug

GEORGE TOWN: Achoo! It’s the flu season, and the virus is making its rounds looking for new carriers during this monsoon season.With cases of influenza A or B on the rise, experts are warning of an outbreak as the virus is highly contagious and prone to spreading during the cold climate.

The common symptoms are high fever, body aches, cough or flu, and nobody is safe from the virus unless one is vaccinated.

Civil servant K. Charles, 38, was out for lunch when he suddenly felt extremely tired and had shortness of breath.“The feeling was like I got hit by a truck and could not continue riding my bike,” he said.

Charles stopped by the roadside to call his father, who then rushed over and sent him to the hospital.

“I was in bed for five days with a high fever and body aches.

“My test result came back positive for influenza A, which the doctors say is highly infectious and more severe than influenza B.“I was given antiviral drugs for the next few days. I lost my appetite and the doctor put me on intravenous (IV) drips.”

Charles said that after he recovered, he promptly went to take a flu jab.

Jessie Lim, a clerk, 43, said she accompanied her son Jason Lee, 23, to a private clinic after he complained about feeling feverish and having body aches.

“At first, I thought he was merely having a fever, but to my surprise, his test showed that he had contracted influenza A.

“He was prescribed antibiotics and paracetamols and told to rest and take more fluids,” she said.

As the disease is highly contagious, Lim said everyone in her family wore masks to contain the spread of the virus and kept her son isolated.

Her anxiety did not end there, as Lim’s 76-year-old mother, who lives with them, also came down with fever, flu and cough.

“I was so worried, thinking that the virus had spread among our family members.

“Luckily, my mother later tested negative for influenza A or B. Both of them recovered after a few days.

“A week later, I took both my son and my mum to a clinic to get the flu vaccines for a whole year’s protection,” she said, adding that she herself had gotten vaccinated against the flu earlier.

Imran Hilmy, who works in the media, was not ready to put his eight-year-old daughter’s life on the line again after she recovered from Covid-19.

“When Maryam and her mother contracted Covid-19 during the pandemic, it was really painful for me to see both of them suffer through it.

“With the influenza season raging now, I did not think twice about getting my daughter vaccinated.

“She needs a boost to her immune system, especially during these colder months when both the flu virus and other respiratory illnesses tend to rise,” he said.

General practitoner Dr BS Goh said people of any age can catch the influenza virus.

The viruses that circulate widely in humans are the influenza A subtypes H1N1 and H3N2, along with influenza B, he said.

“Annual vaccination is recommended as this is the primary and most effective way to prevent influenza and influenza-related complications.”

Dr Goh also advised holidaymakers planning to travel to places with colder climates to get the flu jabs before leaving to avoid falling sick later.

Penang health committee chairman Danial Gooi said staying vaccinated will not only protect individuals but also help safeguard the vulnerable folk within the community.

“Parents, too, should be attentive and refrain from sending their children to daycare centres, kindergartens or schools if they are ill,” he added.

Gooi revealed that the cumulative number of influenza clusters in Penang rose to 27 by epidemic week (EW) 41 this year, up from 21 during the same period last year.However, he said the consultation rate for influenza-like illness (ILI) in EW 41 this year had seen a slight decrease from 8.4% in 2023 to 5.4% this year.

“Although the number of cases per influenza outbreak has shown a significant decline with no serious cases detected in any of the outbreaks, the public still needs to be vigilant about their health and seek immediate treatment if they feel unwell,” he said.

It’s almost always flu season

PETALING JAYA: Although there is a sharp drop in reported influenza cases this year, the highly contagious respiratory illness occurs all year round, says the Health Ministry, while reminding the public to take safety measures against it.

From January to July this year, the ministry logged 158 influenza clusters – compared with 255 clusters during the same period last year.

Of the 158 clusters reported this year, 54% were in schools, followed by kindergartens at 20%.

Health Minister Dr Zaliha Mustafa said the total number of cases reported from the 158 clusters was 4,606, whereas in 2022 the cases were three times higher or 12,876 cases from 255 clusters.

“The ministry still monitors influenza outbreaks and clusters that occur, although individual cases are not required to be notified by clinics and hospitals,” she said in an interview.

This is because influenza, or the flu, is not subject to mandatory notifications under the Prevention and Control of Infectious Diseases Act 1988 (Act 342).

Dr Zaliha said influenza tends to occur all year round and has the potential to attack all ages.

While most people recover within a week without requiring medical attention, some may require admission for close monitoring, she said.

Influenza and the common cold are both contagious respiratory illnesses but caused by different viruses, she added.

“The flu is caused by influenza viruses only whereas the common cold can be caused by a number of different viruses, including rhinoviruses and (human) parainfluenza (viruses),” she said.

Dr Zaliha said the best way to avoid infection is to get the influenza vaccine every year.

She also advised those with symptoms to avoid close contact with others and keep a distance to protect other people from getting sick too.

“Stay home when you are sick. Cover your mouth and nose with a tissue when coughing or sneezing. It may prevent those around you from getting sick,” she said.

Flu viruses, she noted, spread mainly by droplets made when people cough, sneeze or talk.

Dr Zaliha said practising good hand hygiene is also important to curb the spread of the flu.

Germs can also be spread when a person touches something that is contaminated with germs and then touches their eyes, nose or mouth, she said.

Other good health habits – such as cleaning and disinfecting frequently touched surfaces at home, work or school, especially when someone is ill – should also be practised, she added.

“Get plenty of sleep, be physically active, manage your stress, drink plenty of fluids and eat nutritious food. Also seek immediate treatment if symptoms worsen,” she said.

Federation of Private Medical Practitioners’ Associations Malaysia president Dr Shanmuganathan TV Ganeson said the flu season peaks in May to July and November to January.“For the first 24 weeks of 2023 in Malaysia, there was 18.45% positivity for influenza of the specimens sent. The figures for Singapore were quite similar at 20%,” he said.

Dr Shanmuganathan said that as there are pockets of spread, the prevalence would vary from area to area and from time to time.

For example, he said that in May, Klang doctors commented on increased influenza A and B cases, but doctors in Kuala Lumpur did not seem to corroborate that increase.

Symptoms of influenza are fever, flu, cough and chest discomfort, sore throat, lethargy, headache and body aches, respiratory distress, and even vomiting and diarrhoea.

Meanwhile, the symptoms of the common cold are sneezing, stuffy nose, runny nose, sore throat, coughing, mucus dripping down your throat (post-nasal drip), watery eyes and fever.

“However, most people with colds do not have fever,” said Dr Shanmuganathan.

The at-risk groups include children below five years old, the elderly above 65 years old, those with chronic conditions like asthma, diabetes, heart disease or chronic bronchitis, persons with poor immunity like HIV, cancer and chemotherapy patients, healthcare workers and caregivers, he added.

Association of Private Hospitals Malaysia president Datuk Dr Kuljit Singh said Covid-19 has taught the world how to curb the spread of upper respiratory infections, and that the same principles could be applied to flu infections.

“The precautions are pretty similar to Covid-19, such as masking up, social distancing and hand washing – as well as isolation for those infected to control the spread,” he said.

Dr Kuljit also said that in July, private hospitals saw a rise in bed occupancy due to many factors, most notably influenza.
