    COVID-19 cases and deaths have been rising at a worrisome pace since the middle of February with no downturn in sight, and with about a third of all pandemic cases and deaths reported in the last 3 months alone, the World Health Organization (WHO) said yesterday in its weekly snapshot of the pandemic.

    India's cases soar as Brazil's show signs of slowing

    Hot spots continue to vary by region, with the sharpest rises in the region that includes India, where daily cases today topped 300,000 for the first time. Other hard hit areas include the Middle East and the Western Pacific area, though cases are rising in all of the WHO's regions except for Europe.
    The main drivers of recent surges are probably the emergence of more transmissible variants and the inconsistent use and early release of public health measures, the WHO said.
    The five countries reporting the most cases over the past week include India, the United States, Brazil, Turkey, and France. Nations reporting the steepest rises last week include India (64%), Malaysia (45%), South Africa (35%), Argentina (29%), Iran (29%), Japan (29%), and Germany (28%).
    Deaths also continue to accelerate, with the largest increases in the region that includes India, followed by the area that includes Iran.
    At a briefing today, WHO Pan American Health Organization (PAHO) director Carissa Etienne, MBBS, MSc, said there is some sign of slowing in Brazil's massive surge, including in the Amazon region. However, she warned that cases are still alarmingly high, with some cities quick to ease restrictions, which puts the trend in danger of reversing.
    Chile's cases have plateaued, but cases are rising in Colombia, Bolivia, Uruguay, Venezuela, and Argentina, with nearly all countries in Central America reporting increases, Etienne said.

    India's daily total tops 300,000

    India today reported 315,828 new cases today, along with 2,102 more deaths, according to official sources. The United States is the only other country that has reported more than 300,000 cases in a single day.
    New Delhi's hospitals only have 24 intensive care unit (ICU) beds left, and a late-night oxygen delivery kept the facilities from running out, according to the Washington Post.
    In other Indian developments, an oxygen leak at a hospital in Nashik in the western part of the country killed 22 COVID-19 patients who were on ventilators, and the country's Serum Institute said it can boost its production of the AstraZeneca-Oxford vaccine to 100 million doses by July, not May as originally thought.

    Other developments
    • In vaccine developments, some European countries including the Czech Republic, Italy, and the Netherlands today announced they are restarting distribution of the Johnson & Johnson vaccine. And Chile is shifting its vaccine strategy to ensure that people receive two doses, based on data that show low protection from one dose of China's Sinovac vaccine.
    • In drug developments, Japan's Fujifilm has launched a phase 3 trial of favipiravir (Avigan) for the treatment of COVID, and an official from Roche said it and partner Atea Pharmaceuticals are exploring another site to study a COVID-19 antiviral called AT-527, due to declining illness numbers in Britain, according to Reuters.
    • In Asia, Japan is considering a full state of emergency for Tokyo and Osaka areas, and Cambodian police are enforcing the lockdown in Phnom Penh with caning and arrests.
    • The global total today passed 143 million cases, with the number rising to 143,283,366 with 3,049,841 deaths, according to the Johns Hopkins online dashboard.

    Brazil?s Covid-19 vaccination program is being put at risk by people failing to show up for their second shot, with 1.5 million people missing appointments for the follow-up dose needed to maximize protection, according to the Health Ministry.

    Specialists say that is particularly concerning after a recent real-world study from Chile found that the Sinovac Biotech (SVA.O) Covid-19 vaccine, which has accounted for some 80% of Brazil's program, is just 16% effective after one shot.

    ?Without the two doses, we get neither full protection nor a long duration of protection,? Juarez Cunha, head of the Brazilian Society of Immunizations, told Reuters. ?We need people to do the full cycle.?
    ?The only security we have is our ability to adapt."
