Over the past fortnight various news media have reported on increasing numbers of dengue infections in Delhi and, more specifically for DENV-2, across 11 states (Andhra Pradesh, Gujarat, Karnataka, Kerala, Madhya Pradesh, Uttar Pradesh, Maharashtra, Odisha, Rajasthan, Tamil Nadu, and Telangana). Read more. Other articles focused on rising cases of malaria in Uttar Pradesh (Bareilly) and Maharashtra (Gadchiroli and Mumbai). Authorities in Maharashtra said that the spike in confirmed dengue and malaria cases at this time may be due in part to testing facilities returning to more normal functioning after the pandemic peak earlier this year. Elsewhere, Dhaka has reported most of the dengue cases during Bangladesh’s peak season, with fewer than 1,700 infections of the national total of 16,000 from outside the capital. And in Pakistan, surges in dengue infections have been seen in Peshawar, Punjab and the Sindh.
Advice for travellers
Dengue occurs both in urban and rural areas, around human habitation. The virus is spread by Aedes mosquitoes which breed in shady places close to dwellings and bite mainly during the daylight hours, making them difficult to avoid when outdoors. Travellers should cover up with long-sleeved tops, long pants, and shoes and socks when mosquitoes are most active. Apply repellent containing an active ingredient, such as DEET, Picaridin, or oil of lemon eucalyptus (or PMD) when outdoors to all exposed skin.
