Have you heard about tomato flu? The new virus causing this condition has taken over the headlines in the last few months. What started as just a new variant of flu, first identified in Kerala’s Kollam District, has now turned into more than a hundred cases all across India. With the after-effects of the COVID-19 pandemic still being felt all around the globe, the emergence of a new virus is making people anxious. 

Now that the quarantine restrictions have been lifted and the normal way of life has resumed once again, people have become sensitive to new endemic diseases like tomato flu. With the schools having been reopened, the risk of exposure to infections has increased for children. Read on to find out all about what tomato flu is and the precautions required to keep it at bay. 

What is Tomato Flu?

Primarily seen in children between the ages of 1 and 9, Tomato Flu is a rare viral infection that gets its name from bright red blisters, which appear all over an infected person’s body and can grow to the size of tomatoes. It usually manifests in symptoms similar to those of COVID-19. According to a report published by Lancet Respiratory Medicine, Tomato Flu is a non-life-threatening infection in an endemic state (limited to a particular region). Though tomato flu is highly contagious, no casualties have been reported so far.  

Causes of Tomato Flu

While several doctors, scientists, and researchers are investigating tomato flu, the cause of the disease is still unknown. Scientists have confirmed that the new virus is unrelated to SARS-CoV-2. One of the theories states that tomato flu can be an after-effect of dengue fever or chikungunya in children. It could also be a new variant of the hand, foot, and mouth disease (HFMD), which is a common infectious disease seen in children below 5 years of age and immunocompromised adults.

Symptoms of Tomato Flu

The initial symptoms seen in children infected with tomato flu are similar to those of chikungunya. These include:

• Skin rashes and irritation
• High fever
• Swollen and painful joints
• Painful red blisters (resembling those seen in monkeypox infection) 
• Nausea and vomiting
• Fatigue
• Fever
• Dehydration
• Diarrhoea

Parents should consult a doctor immediately if they witness any of these symptoms in their child. 

Diagnosis and Treatment of Tomato Flu

If anyone presents with the symptoms mentioned above, the doctor would recommend several serological and molecular tests to diagnose dengue, Zika virus, chikungunya, herpes, or varicella-zoster virus. Once all of these viral infections turn out to be negative, the possibility of the infection being tomato flu increases. 

Since tomato flu is a self-limiting disease, its symptoms resolve within a few days. As of yet, no antiviral vaccine or drug is available to prevent or treat tomato flu. It is recommended to stay in isolation and take plenty of fluids and rest. 

To relieve skin irritation and rashes, a hot water sponge is highly advisable. Moreover, symptomatic treatment could be required in the form of antipyretics for relieving body aches and fever, topical calamine lotion for blisters, topical mouth gels for oral ulcers, and anti-allergic medications for itching. 

Tomato Flu: Precautions and Prevention 

Since this infection is extremely contagious, it is essential to take certain precautionary steps to prevent it from spreading any further. Some of the preventive and precautionary measures you can take include:

1. Consult with a doctor right away in case you observe the onset of symptoms. 
2. Maintain proper hygiene and keep surrounding necessities and environment properly sanitised.
3. Make sure that an infected child does not share toys, food, clothes, or any other items with non-infected children.
4. Those infected should be isolated for 5-7 days. 

Though tomato flu is not fatal, it is highly contagious. Therefore, being aware of the symptoms and taking the necessary precautions can help control the transmission. Furthermore, once you witness any symptoms, consult a doctor for further investigation. Wish to get expert advice?
