    ‘The biggest monster’ is spreading. And it’s not the coronavirus

    NEW YORK — It begins with a mild fever and malaise, followed by a painful cough and shortness of breath. The infection prospers in crowds, spreading to people in close reach. Containing an outbreak requires contact tracing, as well as isolation and treatment of the sick for weeks or months.

    This insidious disease has touched every part of the globe. It is tuberculosis, the biggest infectious-disease killer worldwide, claiming 1.5 million lives each year.

    Until this year, TB and its deadly allies, HIV and malaria, were on the run. The toll from each disease over the previous decade was at its nadir in 2018, the last year for which data are available.

    Yet now, as the coronavirus pandemic spreads around the world, consuming global health resources, these perennially neglected adversaries are making a comeback.

    “Covid-19 risks derailing all our efforts and taking us back to where we were 20 years ago,” said Dr Pedro L. Alonso, the director of the World Health Organization’s (WHO) global malaria programme.

    It’s not just that the coronavirus has diverted scientific attention from TB, HIV and malaria. The lockdowns, particularly across parts of Africa, Asia and Latin America, have raised insurmountable barriers to patients who must travel to obtain diagnoses or drugs, according to interviews with more than two dozen public health officials, doctors and patients worldwide.

    Fear of the coronavirus and the shuttering of clinics have kept away many patients struggling with HIV, TB and malaria, while restrictions on air and sea travel have severely limited delivery of medications to the hardest-hit regions.

    About 80 per cent of tuberculosis, HIV and malaria programmes worldwide have reported disruptions in services, and one in four people living with HIV have reported problems with gaining access to medications, according to UN AIDS. Interruptions or delays in treatment may lead to drug resistance, already a formidable problem in many countries.

    In India, home to about 27 per cent of the world’s TB cases, diagnoses have dropped by nearly 75 per cent since the pandemic began. In Russia, HIV clinics have been repurposed for coronavirus testing.

    Malaria season has begun in West Africa, which has 90 per cent of malaria deaths in the world, but the normal strategies for prevention — distribution of insecticide-treated bed nets and spraying with pesticides — have been curtailed because of lockdowns.

    According to one estimate, a three-month lockdown across different parts of the world and a gradual return to normal over 10 months could result in an additional 6.3 million cases of tuberculosis and 1.4 million deaths from it.

    A six-month disruption of antiretroviral therapy may lead to more than 500,000 additional deaths from illnesses related to HIV, according to the WHO. Another model by the WHO predicted that in the worst-case scenario, deaths from malaria could double to 770,000 per year.
