Influenza virus can cause pneumonia and brain infections, expert warns
The specialist stressed the importance of annual influenza vaccination, as people can be infected multiple times and severe cases can be deadly.
SHAH ALAM - Influenza infections are on the rise, and public health experts warn that the virus can lead to severe complications like pneumonia, shortness of breath, and even death.
Universiti Kebangsaan Malaysia (UKM) Public Health Medicine Specialist, Professor Dr Sharifa Ezat Wan Puteh said that many people are unaware they have influenza because its symptoms resemble those of Covid-19.
She urged those with flu-like symptoms to seek immediate medical attention and self-isolate, as the virus can spread to others within a six-foot (1.83 metre) radius through coughing or sneezing.
“Influenza is present in Malaysia, but the number of cases fluctuates.
"Everyone is at risk, but severe complications can occur in children, the elderly over 60, and those with conditions like cancer, high blood pressure, diabetes, and obesity, as their immune systems are weaker.
"The influenza virus can reach the brain, cause pneumonia, and shortness of breath, similar to Covid-19.
"In some cases, individuals can contract both Covid-19 and influenza," she told Sinar on Monday.
In rare cases, co-infection with both viruses is possible.
Sharifa addressed the recent surge in influenza cases, highlighting the existence of multiple influenza strains.
Type A, known for causing outbreaks, can spread between birds and humans.
Influenza B, found only in humans, typically causes milder illness.
"Both Type A and B are highly contagious and potentially fatal, but Type A has a higher outbreak potential," she added.
The specialist stressed the importance of annual influenza vaccination, as people can be infected multiple times and severe cases can be deadly.
"We urge the public to get vaccinated against influenza.
"Government subsidies for the vaccine, particularly for the elderly, would be greatly beneficial as the cost is around RM100 annually.
"Since influenza strains change, annual booster shots are recommended," she said.
Types of Influenza A Affecting Humans
- H1N1 (Spanish Flu 1918, Swine Flu 2009)
- H2N2 (Asian Flu, late 1950s)
- H3N2 (Hong Kong Flu, late 1960s)
- H5N1 (Potential Pandemic Threat, mid-2000s)
- H7N9 (Outbreak in China, 2013)
- H7N7 (Potential to Spread Between Animals and Humans)
- H1N2 (Endemic in Pigs)
