Tomato Flue Treatment in Bangalore

India has experienced yet another outbreak of a “highly contagious” viral disease. While medical experts are still battling COVID-19 and monkeypox, a new virus known as tomato flu, or tomato fever, has emerged in India in children younger than 5 years. As per the report published by The Lancet Respiratory Medicine, the rare viral infection is in an endemic state and is considered non-life threatening. The virus was first reported in Kerala on May 6th and since then 82 cases have been reported so far. Moreover, Odisha has also reported 26 cases of tomato flu and all neighbouring states are on alert including Tamil Nadu, Karnataka and Maharashtra.  

Let’s learn about tomato flu, its symptoms, causes, treatment and prevention techniques. 

What is Tomato Flu?

Tomato flu or tomato fever is a rare viral disease causing skin irritation, dehydration, and rashes that affects children mainly under the age of 5. It might not be a new viral infection but could be an after-effect of chikungunya or dengue fever in children. Some studies suggest that tomato flu can be a new variant of the viral hand, foot, and mouth disease, a common infectious disease targeting mostly children aged 1–5 years and immunocompromised adults.

The flu got its name from the emergence of red and painful blisters throughout the body that gradually enlarge to the size of a tomato.

Symptoms of Tomato Flu or Tomato Fever

The initial symptoms of tomato flu resemble those of dengue and chikungunya including high fever, rashes, and intense pain in joints. Rashes and blisters resembling those seen with the monkeypox virus emerge throughout the body which leads to skin irritation. Further symptoms include: 

  • Fatigue

  • Cramps

  • Nausea

  • Vomiting

  • Diarrhoea

  • Fever

  • Dehydration

  • Swelling of joints

  • Body aches

Cause of Tomato Flu Outbreak in India

The exact cause of the tomato virus outbreak is still unknown. Researchers and medical experts are doing further investigations to find out more about the virus that causes tomato fever. 

Dr. Archana M, Consultant - Paediatric Infectious Disease, Manipal Hospital, Old Airport Road, in an interview with The New Indian Express, said that the medical name for ‘tomato flu’ is ‘Hand Foot Mouth disease. She further added, “It is caused by viruses from the enterovirus genus, most commonly the coxsackievirus. It is usually seen among children of less than five years old,”. According to the doctor, tomato flu is a highly contagious infection and can spread through close contact and air. Hence, it is recommended to practice isolation. Young children can catch this virus by touching dirty surfaces, using diapers, and putting objects directly into their mouths.

Treatment of Tomato Flu

As per the Lancet report, tomato flu is a self-limiting disease and no specific drug exists to treat it. Since the symptoms of tomato fever are similar to those of dengue or chikungunya, the treatment technique is also similar. The treatment of tomato flu includes isolation, rest, plenty of fluids, and a hot water sponge for the relief of irritation and rashes. In addition to that, supportive therapy of paracetamol for fever and body ache and other symptomatic treatments are required. Book an appointment today for Tomato Flu Treatment in Bangalore.
