Tomato flu advisory: Use warm water to clean skin, maintain proper hygiene, says Centre

The Centre has issued an advisory on tomato flu after several states reported over 80 cases of the viral disease. It asked the states to follow preventive measures, stressing that there is no specific medication to treat the viral disease.

The disease, which seems to be a variant of Hand, Foot and Mouth Disease (HFMD), occurs mainly in children under 10 years of age, but it can occur in adults too, an advisory issued by the Centre said, adding that the children must be educated about the signs and symptoms and side-effects of the illness.

Although the tomato flu virus shows symptoms similar to other viral infections (fever, fatigue, body aches and rashes on the skin), the virus is not at all related to SARS-CoV-2, monkeypox, dengue and/or chikungunya, it said.

Symptoms

Primary symptoms observed in children with tomato flu are similar to those of other viral infections, which include fever, rashes and pain in joints. The symptoms also include fatigue, nausea, vomiting, diarrhoea, fever, dehydration, swelling of joints, body aches, and common influenza-like symptoms.

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, read the advisory.

Advisory

The advisory stated, "It seems, the disease is a clinical variant of the so-called hand-foot-mouth disease (HFMD) that is common in school going children."

Infants and young children are also prone to this infection through the use of nappies, touching unclean surfaces as well as putting things directly into the mouth, it added.

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 -- 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.
• The advisory also said that isolation should be followed for five to seven days from onset of any symptom to prevent the spread of infection to other children or adults.
• The best solution for prevention is the maintenance of proper hygiene and sanitization of the surrounding necessities as well as preventing the infected child from sharing toys, clothes, food, with other non-infected children.
• Avoid immediate contact with the infected person.
• Tell your child not to hug or touch children having fever or rash symptoms.
• Encourage children to stop thumb or finger sucking habits.
• Encourage the child to use a handkerchief in case of running nose or coughing," it read.
• One should not scratch or rub the blister. Children should be kept hydrated.
• Always use warm water to clean skin or for bathing the child.
• Take a nutrition-rich, balanced diet to boost immunity.
• It is essential to get enough rest and sleep to promote healing.
• Till now, no antiviral drugs or vaccines are available for the treatment or prevention of tomato flu.

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 two to four weeks to obtain the laboratory results.

The testing should be done for investigation of an outbreak, so that preventive measures can be initiated, the advisory said.

Tomato flu or tomato fever is a viral disease, which derives its name from its main symptom -- the tomato-shaped blisters on several body parts, said the advisory. It is a self-limiting disease, as the signs and symptoms resolve after a few days.
