Hot Topics in Infection prevention and Control: February 2025 Update
January may have been the longest month ever, but we’re finally in February! as we dive into the latest developments in public health, here’s a comprehensive look at the most pressing issues shaping the landscape of infection prevention and control.
Respiratory Virus Season Updates

With much of the CDC’s website pulled down in last week’s purge of public health data, experts are relying heavily on the US weekly flu surveillance report for Week 4 (ending january 25, 2025). Clinical lab test positivity for influenza stands at 29.4%, reflecting an increasing trend. Outpatient respiratory illnesses have risen to 6.9%, signaling a challenging season ahead.
For COVID-19, test positivity is at 5.4%, with a hospitalization rate of 4.0 per 100,000. Additionally, 0.9% of emergency department visits are attributed to COVID-19. These figures underscore the ongoing impact of respiratory viruses on public health.
H5N1 Outbreaks in Poultry and Dairy Farms
The US Department of Agriculture (USDA) Animal and Plant Inspection Service (APHIC) has reported new outbreaks of H5N1 across three states. five farms in Missouri, a commercial turkey farm in California, and a backyard flock in Oregon have been affected. Missouri has been particularly hard hit, with 4.3 million birds impacted or lost in the last month.
In the dairy sector, another farm in California has reported infected cows, bringing the state’s total to 736 affected herds and a national total of 957. These developments highlight the ongoing challenges in controlling the spread of H5N1 in both poultry and livestock.
Public Health Politics
Robert F. Kennedy, Jr. has advanced to the first round of his confirmation hearing, bringing him one step closer to leading the US Department of Health and Human Services.The Senate vote is expected within the next week.
Meanwhile, US Agency for International Development (USAID) workers have been recalled from their posts worldwide, leaving many scrambling to manage career and relocation changes. The move to abolish USAID has drawn intense criticism, with many questioning its legality and global impact.
In another meaningful development, the National Science Foundation (NSF) has announced that roughly 25 to 50% of its staff will be laid off in the next two months. Additionally, President Trump signed an Executive Order on February 4, 2025, to withdraw the US from the United Nations Human Rights Council.
Ebola Outbreak in Uganda and Marburg in Tanzania
Uganda has reported a new case in the ongoing Ebola Sudan outbreak. The initial case, a 32-year-old male nurse, died with an unknown source of exposure. His wife is now the second confirmed case, with 234 close contacts identified. Of these, 118 have sought health care, and three are under isolation awaiting testing.
In the United Republic of Tanzania,a Marburg virus disease outbreak was declared on january 20,2025. so far, there have been 10 cases and 10 deaths, with no new cases reported since the outbreak began. A total of 281 contacts have been identified.

As February 2025 unfolds, the global public health landscape continues to face significant challenges. From the ongoing Ebola outbreak in Uganda to the Marburg virus cases in Tanzania, and also the resurgence of respiratory viruses and H5N1 in poultry and dairy farms, staying informed is critical. In this exclusive interview, senior Editor Sarah Carter from world-today-news.com sits down with Dr. Emily Harper, a leading infectious disease specialist, to unpack these pressing issues and explore what’s next for infection prevention and control.
Understanding the Current Ebola Outbreak in Uganda
Sarah Carter: Dr. Harper, let’s start with the Ebola outbreak in Uganda. Can you provide an overview of the situation and its implications?
Dr. Emily Harper: Certainly, Sarah. Uganda is currently grappling with the Ebola Sudan strain,which has claimed the life of a 32-year-old male nurse believed to be the index case. His wife has since been confirmed as the second case, and 234 close contacts have been identified. Of these, 118 are seeking care, and three are in isolation awaiting testing. While the source of the initial infection remains unknown, this outbreak underscores the importance of rapid identification, isolation, and contact tracing to prevent further spread.
The Marburg Virus in Tanzania: A Closer Look
sarah Carter: Moving to Tanzania,there’s been a concerning outbreak of the Marburg virus. What’s the current status,and how does it compare to Ebola?
Dr. Emily Harper: The Marburg virus,like Ebola,is a severe and often fatal hemorrhagic fever. As the outbreak was declared on January 20,there have been 10 confirmed cases and 10 deaths,with no new cases reported recently. Tanzania has identified 281 contacts for monitoring.While the case count is lower than Uganda’s Ebola situation,the 100% fatality rate so far is alarming. Both outbreaks highlight the need for robust surveillance systems and community engagement to mitigate risks.
Respiratory Virus Season: Influenza and COVID-19 Trends
Sarah Carter: Let’s shift gears to respiratory viruses. The CDC’s latest data shows rising trends in influenza and COVID-19. What are the key takeaways?
Dr. Emily Harper: The data for Week 4 of 2025 paints a challenging picture. Influenza test positivity stands at 29.4%, indicating a sharp increase in cases.Outpatient respiratory illness visits have risen to 6.9%, which is significant. For COVID-19,the test positivity rate is 5.4%, with a hospitalization rate of 4.0 per 100,000.Additionally, 0.9% of emergency department visits are attributed to COVID-19. These figures remind us that both viruses remain formidable threats, especially during the winter months.
H5N1 Outbreaks in Poultry and Dairy Farms
Sarah Carter: The H5N1 virus has been making headlines, particularly in poultry and dairy farms. What’s the latest, and why is this concerning?
Dr. Emily Harper: H5N1 is a highly pathogenic avian influenza virus that has now spread to both poultry and dairy herds. Recently, outbreaks were reported in Missouri, California, and Oregon, with Missouri losing 4.3 million birds in the past month alone. In the dairy sector, california has seen the most significant impact, with 736 affected herds and a national total of 957. this virus poses a dual threat: not only does it devastate livestock industries,but it also has the potential to jump to humans,though such cases remain rare.
Public Health and Political Developments
Sarah Carter: let’s touch on some recent public health politics. Robert F. Kennedy,Jr. is poised to lead HHS, and USAID workers are being recalled. How might these changes impact global health efforts?
Dr. Emily Harper: These developments are significant. Robert F. Kennedy,Jr.’s potential leadership of HHS could bring a new direction to U.S. health policies. Simultaneously occurring, the recall of USAID workers and the agency’s potential abolition have raised concerns about the continuity of global health programs, especially in regions dependent on U.S. aid. Additionally, the layoffs at the National Science Foundation and the U.S. withdrawal from the UN Human Rights Council suggest a shift in priorities. These changes could have far-reaching consequences for both domestic and international health initiatives.
Conclusion
as we navigate these complex public health challenges, it’s clear that vigilance, collaboration, and informed decision-making are more critical than ever. Whether it’s addressing the Ebola and Marburg outbreaks, managing respiratory virus seasons, or mitigating the impact of H5N1, staying ahead of these threats requires a multifaceted approach. Thank you, Dr. Harper, for your invaluable insights today.
