Travelers preparing to journey to Asia are being urged by doctors to take precautionary measures against mosquito-borne infections like dengue and malaria, with vaccinations recommended four to six weeks before departure. The UK Health Safety Agency (UKHSA) has issued a warning, noting a surge in cases of these diseases, reaching levels not observed since 2019.
While dengue typically manifests as flu-like symptoms and is generally mild, it can escalate to severe illness in certain instances. Meanwhile, malaria poses a more significant threat, causing symptoms such as fever, headache, and muscle aches, with potentially fatal consequences. Most reported cases in the UK have originated from travel to South and Southeast Asia, notably India, with a notable increase observed in Central America and the Caribbean as well.
Dr. Dipti Patel, Director of the National Travel Health Network and Center, emphasized the importance of prioritizing health and planning for overseas travel. Travelers are advised to seek medical attention promptly if feeling unwell, especially after recent travel.
Dr. Philip Well, a public health advisor at UKHSA, outlined straightforward preventive measures to minimize the risk of infection, including applying insect repellent, wearing protective clothing, and utilizing bed nets. It’s crucial to recognize that even individuals with prior exposure to certain regions may lack immunity against local infections, emphasizing the need for proactive health measures.
The Travel Health Pro website, supported by UKHSA, offers comprehensive information on health risks in various countries worldwide. Travelers are encouraged to consult with healthcare professionals—such as GPs, nurses, or pharmacists—regarding potential vaccinations well in advance of their travel dates to ensure adequate protection against mosquito-borne illnesses.
