The image was taken on August 21 at 7.03 p.m. UTC (12.33 a.m. IST on August 22) by the Chandrayaan 2’s LI4 camera, ISRO said. On August 4,  ISRO released the first picture of the Earth  captured by Chandrayaan 2’s Vikram Lander. On August 21, Chandrayaan 2, a day old in its orbit around the moon, started undergoing phased maneuvers to shorten the elliptical orbit in preparation for the September 7 landing.  ISRO said it compressed the current elliptical orbit to  4,412 km at the far end from the moon. The orbit exercise was performed for about 20 minutes from 12.50 p.m. by firing the onboard motors. Earlier in the day, ISRO chief K. Sivan said the crucial process of taking up the soft landing of the Vikram Lander will be taken up in the early hours of September 7. ISRO scientists in Bengaluru would be engaged in this process which is expected to be completed by 1.55 a.m., he told reporters at the airport in Chennai on August 22. “It is expected to make a so...

                      CHOLERA                                       Cholera is an acute, watery diarrhoeal disease caused by Vibrio cholera of the O1 or O139 serogroups. In the past two centuries, cholera has emerged and spread from the Ganges Delta six times and from Indonesia once to cause global pandemics. Rational approaches to the case management of cholera with oral and intravenous rehydration therapy have reduced the case fatality of cholera from more than 50% too much less than 1%. Despite improvements in water quality, sanitation, and hygiene, as well as in the clinical treatment of cholera, the disease is still estimated to cause about 100 000 deaths every year. Most deaths occur in cholera-endemic settings, and virtually all deaths occur in developing countries. Contemporary understanding of immune protection against cholera...

                  MEASELS                          Measles is a highly contagious disease that results from infection with measles virus and is still responsible for more than 100 000 deaths every year, down from more than 2 million deaths annually before the introduction and widespread use of measles vaccine. Measles virus is transmitted by the respiratory route and illness begins with fever, cough, coryza, and conjunctivitis followed by a characteristic rash. Complications of measles affect most organ systems, with pneumonia accounting for most measles-associated morbidity and mortality. The management of patients with measles includes the provision of vitamin A. Measles is best prevented through vaccination, and the major reductions in measles incidence and mortality have renewed interest in regional elimination and global eradication. However, urgent efforts are needed to...
