Tomato Flu: Causes, Symptoms, and Treatment (2025)

Tomato flu is a viral infection that primarily affects children under five years old. First identified in Kerala, India, in 2022, the disease is named for the red, tomato-like blisters that appear on the skin of those infected.

Tomato flu is similar to hand, foot, and mouth disease and is characterized by fever, rashes, and joint pain.

Understanding the symptoms, transmission, and preventive measures of tomato flu is crucial for managing outbreaks and ensuring the health and safety of vulnerable populations.

What is the Tomato Flu?

Tomato flu, also known as tomato fever, is a viral infection that primarily affects young children. It was first identified in Kerala, India, in May 2022. The name “tomato flu” comes from the red, tomato-like blisters that appear on the skin of infected individuals.

These blisters resemble those seen in hand, foot, and mouth disease, with which tomato flu shares many similarities.

While the disease is typically mild and self-limiting, it can cause significant discomfort, especially in young children.

Tomato flu is believed to be spread through close contact with infected individuals, making it highly contagious among children who often play together. The exact virus responsible for tomato flu is not well-defined, but it is thought to be related to enteroviruses, which are responsible for hand, foot, and mouth disease.

Preventive measures for tomato flu include practicing good hygiene, such as frequent handwashing, avoiding close contact with infected individuals, and disinfecting contaminated surfaces.

While there is no specific treatment for tomato flu, symptoms can be managed with supportive care, including rest, hydration, and over-the-counter pain relievers.

Due to its recent emergence, further research is needed to fully understand tomato flu and its long-term implications. Public health efforts continue to focus on containing outbreaks and preventing the spread of this infection among vulnerable populations.

Causes

The specific cause of tomato flu is not yet fully understood, but it is believed to be a viral infection similar to other viral diseases affecting children, such as hand, foot, and mouth disease.

Here are some of the key factors believed to contribute to the spread and cause of tomato flu:

• Viral Infection: Tomato flu is thought to be caused by a virus, possibly related to the family of enteroviruses. Enteroviruses are a group of viruses that commonly cause infections in humans, especially in children. They are known for causing symptoms similar to those of tomato flu, such as fever, rashes, and blisters.
• Close Contact Transmission: Tomato flu is highly contagious and spreads through close contact with infected individuals. It is primarily transmitted through direct contact with the blisters or bodily fluids of an infected person. Young children, who often play closely together, are particularly vulnerable to contracting the virus.
