Scrub typhus is prevalent in India although definite statistics are not available. There has been only one study on scrub typhus meningitis 20 years ago. Most reports of meningitis/meningoencephalitis in scrub typhus are case reports A retrospective study done in Pondicherry to extract cases of scrub typhus admitted to hospital between February 2011 and January 2012. Diagnosis was by a combination of any one of the following in a patient with an acute febrile illness- a positive scrub IgM ELISA, Weil-Felix test, and an eschar.

Variations in nearshore wave power at four shallowwater locations along the east and west coast of India are examined based on the measured wave data for one-year period. The study shows that along the west coast of India, 83–85% of the annual wave power is during the summer monsoon period (June–September), whereas at Visakhapatnam (on the east coast), 55% of the annual wave power is during the summer monsoon period. Along Puducherry coast in the east, wave power is relatively less with maximum value of 31.8 kW m–1.

Mangroves are salt tolerant plants that occur between 32°N and 38°S latitudes. Mangroves play an important role in stabilizing shoreline and protect the coast against storm surges and heavy tides. Though the mangrove inventory has been done earlier in India using satellite data but no systematic attempts has been made to map the mangroves at the community level for the entire country. The present paper reports the mangrove inventory at community level for India using Resourcesat-1 satellite data. State wise inventory on the mangrove area and the dominant communities are presented.

The main objective of this study was to assess the effectiveness of a mangrove barrier against cyclone, storm and strong tidal waves. (Correspondence)
