New Delhi: The Centre on Tuesday issued an advisory to states on Hand Foot and Mouth Disease (HFMD), commonly known as Tomato Flu.
According to the Ministry of Health and Family Welfare, Tomato Flu was first identified in the Kollam district of Kerala on May 6 and as of July 26, more than 82 children younger than 5 years with the infection have been reported by the local government hospitals. The other affected areas of Kerala are Anchal, Aryankavu, and Neduvathur.
This endemic viral illness triggered an alert to the neighboring states of Tamil Nadu and Karnataka. Additionally, 26 children (aged 1-9 years) have been reported as having the disease in Odisha by the Regional Medical Research Centre in Bhubaneswar. To date, apart from Kerala, Tamil Nadu, Haryana and Odisha, no other regions in India have reported the disease in their State/UT by the virus.
Tomato Flu is a viral disease. The name "Tomato Flu" comes from the main symptom of this disease, the tomato-shaped blisters on several body parts. The blisters start as red-colored small blisters and resemble tomatoes when they enlarge.
Primary symptoms observed in children with Tomato Flu are similar to those of other viral infections, which include fever, rashes and pain in joints. Rashes on skin can also lead to skin irritation. As with other viral infections, symptoms also include, fatigue, nausea, vomiting, diarrhea, fever, dehydration, swelling of joints, body aches, and common influenza-like symptoms, the Union Health Ministry said.
HFMD is characterized by fever, sores in the mouth, and a skin rash. It begins with mild fever, poor appetite, malaise, and often a sore throat. One or two days after the fever begins, small red spots appear which changes to blister and then to ulcers. The sores are usually located on tongue, gums, inside of the cheeks, palms and soles.
In children with these symptoms, molecular and serological tests are done for diagnosis of dengue, chikungunya, zika virus, varicella-zoster virus, and herpes; once these viral infections are ruled out, a diagnosis of tomato flu is considered.
Tomato Flu is a self-limiting infectious disease as the signs and symptoms resolve after a few days. It seems, the disease is a clinical variant of the so-called hand-foot-mouth disease that is common in school going children. Infants and young children are also prone to this infection through use of nappies, touching unclean surfaces as well as putting things directly into the mouth. HFMD occurs mainly in children under 10 years of age, but it can occur in adults too. There are no disease-specific medications available. Treatment is similar to other viral infections i.e. isolation, rest, plenty of fluids and hot water sponge for relief of irritation and rashes. Supportive therapy of paracetamol for fever and body ache and other symptomatic treatments are required.
Isolation should be followed for 5-7 days from the onset of any symptom to prevent the spread of infection to other children or adults.
The best solution for prevention is maintenance of proper hygiene and sanitization of the surrounding necessities and environment as well as preventing the infected child from sharing toys, clothes, food, or other items with other non-infected children.
As yet, no antiviral drugs or vaccines are available for the treatment or prevention of tomato flu. Further follow-up and monitoring for serious outcomes and sequelae are needed to better understand the need for potential treatments.
Hand Foot and Mouth Disease (HFMD) is one of the many infections that result in mouth sores. However, health care providers can usually tell the difference between HFMD and other causes of mouth sores by considering the patient's age, the symptoms reported by the patient or parent, and the appearance of the rash and/or sores. Diagnosis is largely clinical.
Samples from throat or stool may be sent to a laboratory to test for isolating the virus involved in causing the illness, which may take 2-4 weeks to obtain the laboratory results. The testing should be done for investigation of an outbreak, so that preventive measures can be initiated.
On Sample collection, the Health Ministry said throat or nasopharyngeal samples can be collected within 48 hours of illness. Faecal samples should be collected within 48 hours of illness.
