Analyzing the impact of the 2024-2025 influenza season and future predictions.
Current Flu Season: A Cause for Concern?
As influenza continues to spread, experts are closely monitoring the trends and severity of the current flu season. Some are suggesting that this year could be one of the most challenging in recent memory.
Director of the WHO Collaborating Center for Studies on the Ecology of Influenza, Dr. Richard Webby, stated that predicting the severity of New Zealand’s flu season is tough, but emphasized that the virus poses a threat every year.
While the United States experienced a important flu season, Dr. Webby noted the uncertainty in applying those trends to New Zealand:
History doesn’t really help us in this case. So just because we’ve had a big old season in the US, it doesn’t necessarily mean it’s going to be the same for the Kiwi winter coming up.
He further explained the limitations in predicting the severity of the flu season:
Looking to what happened in the Northern Hemisphere helps to predict which viruses might be coming. But in terms of how severe the season’s going to be, it’s sadly not that much use to us.
Dr. Webby admitted,
If we could understand it,of course,we’d be a little bit better at predicting it but we’re lousy at that as well.
Severity and Impact in the U.S.
The U.S. is grappling with what experts are calling the worst flu season as 2009. The Centers for Disease Control and Prevention (CDC) data indicates a “high-severity” season, with significant numbers of cases, hospitalizations, and deaths.
As of February 8, estimates included at least 29 million cases, marking the highest figure since the 2009-2010 flu season. The impact has been substantial, with at least 370,000 hospitalizations and 16,000 deaths attributed to the flu, according to the CDC.
2024-2025 Flu Season Statistics
data from the 2024-2025 flu season reveals a concerning impact on public health. Experts warn that the season has not yet peaked and could worsen.
As of the week ending in February, the U.S. had already seen at least 24 million illnesses, 310,000 hospitalizations, and 13,000 deaths linked to the flu, including 57 children.

Understanding Influenza Transmission
Despite advancements in understanding influenza,many aspects of it’s transmission remain unclear. Dr. Webby highlighted the gaps in our knowledge:
there’s a lot we don’t know about it.
He elaborated on the unpredictable nature of household infections:
In terms of when people get infected in a household some people get infected, some don’t. We don’t really understand why that is.
The phenomenon of “super spreaders” also adds complexity to the transmission dynamics:
Sometimes some people [are] what we call super spreaders, and they’ll spread it to a lot of people.
Dr.Webby acknowledged,
You’d think we’d know but we really don’t.
The Importance of Vaccination
Regardless of the severity of a given flu season,vaccination remains the most effective preventive measure.Dr. Webby emphasized the collective benefit of widespread vaccination:
clearly the more people we get vaccinated, the better off we’re going to be.
He also noted the benefits of high-dose vaccines, particularly for the elderly and those in high-risk groups:
The high dose vaccine – which is really made particularly for the elderly – it does do a better job.
Dr. Webby advised,
Particularly if you’re in, sort of, risk groups – particularly the elderly – if you can get your hands on the high dose vaccine, and can afford to pay for it, it is indeed an excellent idea.
The Flu’s Deadly Potential
Influenza should not be underestimated, as it can have severe consequences. Dr. Webby highlighted the global impact of the flu:
Up to 600,000 die of influenza a year around the globe. So it can just be a sniffle, and sort of, put you out of your peak performance for a day or two. But it absolutely can be deadly, and it’s deadly every year. It’s deadly in the US every year and it’s deadly in New Zealand every year as well.

Flu Season Severity and Predictions
Q: How severe is the current flu season?
The U.S. experienced a significant flu season in 2024-2025, with at least 24 million illnesses, 310,000 hospitalizations, and 13,000 deaths reported by February. Experts are closely monitoring trends, but predicting the severity of the flu season remains challenging. As of February 8, estimates included at least 29 million cases and the season could worsen.
Q: Can we predict how severe the flu season will be in different regions?
Predicting the severity of a flu season is difficult due to the virus’s unpredictable nature. According to Dr. Richard Webby, director of the WHO Collaborating Center for Studies on the Ecology of Influenza, trends from one region (like the U.S.) don’t necessarily translate to another (like New Zealand).
Q: What factors make flu season prediction so challenging?
Several factors contribute to the difficulty in predicting flu season severity, including:
Viral Evolution: Influenza viruses constantly change.
Unpredictable Transmission: The ways the flu spreads, including within households and through “super-spreaders,” are not fully understood.
Geographic Variability: Flu seasons vary significantly between different regions, making it hard to extrapolate from one area to another.
Influenza Transmission
Q: What don’t we certainly know about how the flu spreads?
Despite advancements, there are still knowledge gaps regarding flu transmission dynamics:
Household Transmission: Why some members get infected in a household, while others don’t, remains unclear.
Super-Spreader Events: The factors that cause some individuals to spread the virus to many people are not fully understood.
The Importance of Vaccination
Q: Why is flu vaccination vital?
Vaccination is the most effective preventive measure against influenza. Widespread vaccination helps protect individuals and the community. As Dr. Webby states,”clearly the more people we get vaccinated,the better off we’re going to be.”
Q: Are some flu vaccines better then others?
High-dose vaccines are especially beneficial for the elderly and those in high-risk groups.These vaccines offer enhanced protection compared to standard doses.
flu’s Impact and Severity
Q: Is the flu really that serious?
Yes, influenza can have severe consequences. Globally, up to 600,000 people die from influenza each year.
Q: What are the potential complications of the flu?
While the flu can cause mild symptoms, it can also lead to serious complications, including:
Pneumonia
Hospitalization
Death
