Heavy smog compelled New Delhi to declare a pollution emergency last week. As air pollution soared to hazardous levels and residents donned masks, India’s capital took a series of measures, such as banning most commercial trucks from entering the city and closing all schools, in response to the air quality crisis. Many residents complained of headaches, coughs and other health concerns, and poor visibility caused major traffic accidents.
On September 20th, 2017, a young hunter, in his 30s, arrived at a health center in Kween District, located in Eastern Uganda, on the border with Kenya. He had symptoms of fever, bleeding, diarrhea, and vomiting. Within 5 days he was dead. Two weeks later, his sister also showed up at the same health facility: she had similar symptoms. Within a week, she too was dead. Posthumous samples confirmed that she had Marburg Virus Disease (MVD), one of the most virulent pathogens known to infect humans. On 19th October, the Ugandan government notified WHO and publicly announced an outbreak of MVD. Not long after this announcement, MVD claimed another victim – this time, the hunter’s brother.
