It is unequivocal that climate change is happening and is likely to expand the geographical distribution of several vector-borne diseases, including malaria and dengue etc. to higher altitudes and latitudes. India is endemic for six major vector-borne diseases (VBD) namely malaria, dengue, chikungunya, filariasis, Japanese encephalitis and visceral(More)
World Health Assembly resolution in 1997 for elimination of lymphatic filariasis (ELF) by 2020 made all the filaria endemic countries in the world to put efforts for its elimination by progressively reducing and ultimately interrupting the transmission of lymphatic filariasis. National Health Policy, 2002 has set the goal for elimination of lymphatic(More)
After the launch of the National Malaria Control Programme in 1953, the number of malaria cases reported in India fell to an all-time low of 0·1 million in 1965. However, the initial success could not be maintained and a resurgence of malaria began in the late 1960s. Resistance of Plasmodium falciparum to chloroquine was first reported in 1973 and increases(More)
Japanese encephalitis (JE) has been prevalent in various countries of East and South-East Asia since long. In India, JE virus activity was, however, first detected in 1952 through sero-epidemiological surveys in Nagpur district of Maharashtra and Chingleput district of Tamil Nadu. Japanese encephalitis as a disease was first reported in 1955 when cases of(More)
Kala-azar has been endemic in India for a long time. Phlebotomus argentipes, the vector became resurgent during 70s in four districts of Bihar and slowly spread to other parts of south Bihar and several districts of West Bengal. Kala-azar is a present endemic in 31 districs of Bihar, 4 districts of Jharkhand, 11 districts of West Bengal besides occurring is(More)
A study was conducted from 1996 to 2001 on well drained sandy loam soils in the central plain region of Punjab to determine the effect of initial size of planting stock and clones of poplar (Populus deltoides) on their height, diameter and volume growth. Two categories of planting stock viz. large size (height >4.7 m and collar diameter >4.2 cm) and small(More)
We evaluated the growth and crown traits of 36 poplar clones at two distinct agro-climatic regions of Punjab (Ludhiana and Bathinda) in northwestern India, following randomized block design with three replications and plot size of four trees. Significant differences among clones (p<0.001) were observed for diameter at breast height (DBH), tree height,(More)
For a long time malaria control in India has largely been a government responsibility with little involvement of the community at large, and other sectors of the economy in the control efforts. There is now increasing realisation that involvement of the community and a multi-sectoral approach should be essential components of the malaria control strategy.(More)
