Explanation:

All statements are correct.

• The infection has been named ‘tomato flu’ because of the red, painful blisters that appear on a patient’s body and gradually enlarge to the size of a tomato.
• This flu is a self-limiting one and there is no specific drug for this.
• The infectious disease is caused by intestinal viruses and is rare in adults as they usually have immune systems strong enough to defend them from the virus.
• The treatment for tomato flu is similar to the treatment of chikungunya, dengue and hand, foot, and mouth disease.
• Patients are advised to isolate, rest, plenty of fluids, and hot water sponge for the relief of irritation and rashes.

Hence option 4th is correct.
