The victims caused in Brazil by Covid-19 in a pandemic year have already exceeded those for AIDS recorded in the last 23 years. The deaths from Covid-19 are currently 284,775 while those caused by AIDS from 1996 to 2019 are 281,156. This was revealed by the Ministry of Health, which has been monitoring AIDS victims only since 1996 even though Acquired Immunodeficiency Syndrome has been present in Brazil since 1982. The annual average of victims caused by AIDS in Brazil ranges between 10 and 12 thousand, specifies the ministry.
The UN studies the effects of weather and smog on the pandemic
Covid transmission could become seasonal, but there is not yet enough data to suggest relying on weather conditions and air quality to adapt pandemic control measures. More than a year after the outbreak of the disease in China, there are still unknowns about its transmission. As a result, the World Meteorological Organization (WMO), a specialized agency of the United Nations, has set up a task force of 16 experts to study the influence of weather and air quality factors on the pandemic. Their first report finds that the seasonality of respiratory viral diseases – particularly the peak of the cold season for flu and cold-causing coronaviruses in temperate climates – suggested that Covid “would be a highly seasonal disease if it persisted for several. years”. Process modeling studies have shown that its transmission “could become seasonal over time, suggesting that it would be possible to rely on weather and air quality factors to monitor and predict” the disease in the future. However, the WMO researchers still say that it is still too early to consider these factors, and the WMO notes that the dynamics of Covid transmission last year “seems to have been governed mainly by government interventions rather than weather factors. “. “At this stage, the available data does not support the use of weather and air quality factors to allow governments to relax measures they are taking to reduce transmissions,” said Dr Ben Zaitchik, co-chair of the task. force and member of the Department of Earth and Planetary Sciences of Johns Hopkins University, Baltimore. “In the first year of the pandemic, we have seen waves of contamination during warm seasons and in hot regions. There is no evidence that this will not happen again in the next year,” he added in a statement. Again: while laboratory studies have found some evidence that the virus survives longer in cold, dry conditions with low ultraviolet radiation, they have not yet indicated whether meteorological factors have a significant influence on transmission rates in real-world conditions. According to the task force, there is still no conclusive evidence of the influence of air quality factors. Although preliminary data show that poor air quality increases death rates, pollution has not been shown to have a direct impact on airborne transmission of SARS-CoV-2.
Covid: China records 6 new cases, all from abroad
China’s National Health Commission has announced 6 new cases of SARS-CoV-2 coronavirus infection, all from outside its borders. The six infected are travelers from abroad in the metropolitan area of Shanghai (east, 2), and in the provinces of Tianjin (north-east, 3) and Guangzhou (south-east, 1). With these figures – not even a single local infection since last February 15 – China extends the downward trend in terms of new positives: the Asian country detected 4 cases on Tuesday, 13 cases on Monday, 5 on Sunday and 10 on Saturday . In addition, health authorities also reported today the detection of 6 new asymptomatic infections (all from abroad), although Beijing does not include them as confirmed cases unless they show symptoms. The total number of such infections under observation is 261, all “imported”. In addition, the Commission also announced the discharge of 13 recovered patients.
