    planet to help it reach another planet, helping Mariner 10 reach Mercury in Mar 1974.

    1971 – Third U.S. manned moon landing

  • Pandemic again??

    The mysterious lung disease is reported in parts of China.

    There has been a spike in reported incidents of respiratory illnesses. The illnesses has caused a surge in hospitalisations. Infections have reported from China’s north-eastern regions. Cases among children are especially high, schools in Beijing are reporting high levels of absenteeism.

    Apart from children, the elderly and pregnant women are also vulnerable.

    Chinese authorities have asked the public to step up vigilance.

    WHO has given the advisory for keeping distance from people who are ill, Staying home when ill Getting tested and medical care as needed Wearing masks as appropriate, Ensuring good ventilation and regular hand-washing

    Authorities have warned of the risk of a rebound in Covid-19 infections, and asked for strengthening the reporting process. China has ramped up testing and surveillance. Given the experience of the pandemic a couple of years back, authorities are likely to be doubly cautious.

    It time to be vigilant again

    Till the Date no case is reported from India. It is observed that the incidence of illness is affecting the children as no case is reported in the elders, Therefore it is implied that the kids are getting infected because they are not vaccinated. The disease is similar to Pneumonia and it is said that the rise is infection is due to cold in the region.

    Whatever be the case it should not be the deadly Pandemic again…
