The Centers for Disease Control and Prevention (CDC) has issued a warning on several ongoing disease outbreaks across the world, highlighting the urgent need for public awareness and intervention.

According to the CDC’s current outbreak list, dengue fever has surged in regions such as Puerto Rico and the U.S. Virgin Islands, with over 760,000 cases reported globally as of early March 2025.

This marks a 15 per cent increase compared to previous years, prompting health authorities to declare an epidemic in Puerto Rico.

As global travel resumes, the spread of diseases like dengue fever, which is transmitted by mosquitoes, poses a significant risk, particularly in tropical and subtropical regions. 

In Kenya, the situation is no different, as multiple disease outbreaks continue to strain the country’s public health system.

The ongoing heavy rains have led to an upsurge in malaria cases, particularly in Baringo and Turkana counties.

Stagnant water, a breeding ground for mosquitoes, has contributed to increased transmission, with thousands of cases being reported.

In response, organisations such as Doctors Without Borders (MSF) have deployed mobile clinics to affected areas, offering malaria treatment and distributing mosquito nets to vulnerable communities. 

At the same time, Marsabit County is grappling with a measles outbreak, prompting the government and health agencies to launch mass vaccination campaigns.

Nearly 10,000 children aged between nine months and 15 years have already been immunised in a bid to contain the spread.

The recent outbreaks mirror Kenya’s long-standing battle with infectious diseases. Between 2007 and 2022, the country recorded 457 outbreaks, with counties like Garissa, Nairobi, Nakuru, Wajir, Mandera and Mombasa accounting for nearly a quarter of these cases.

Nairobi, being the most populous, has historically recorded the highest number of cases and fatalities. 

With the rising burden of infectious diseases, public health experts are urging Kenyans to take preventive measures. Malaria cases can be minimised by using insecticide-treated mosquito nets and reducing stagnant water sources.

Parents are encouraged to ensure their children receive routine immunisations to prevent vaccine-preventable diseases such as measles.

As for dengue fever, travellers to high-risk areas are advised to use mosquito repellents and stay in accommodations with proper screening or air conditioning. 

The CDC continues to monitor global outbreaks and provide updates on emerging health threats. Staying informed and adhering to recommended guidelines remains crucial in preventing and controlling the spread of infectious diseases.
