Bacteria pneumonia can spread to the bloodstream and cause sepsis, which is extremely dangerous and can be quickly fatal. And pockets of pus can form inside or around the lungs, and they may need ...
In May 2022, a preprint indicated Omicron subvariants BA.4 and BA.5 could cause a large share of COVID-19 reinfections, beyond the increase of reinfections caused by the Omicron lineage, even for people who were infected by Omicron BA.1 due to increases in immune evasion, especially for the unvaccinated. However, the observed escape of BA.4 and ...
During the 2002–2004 SARS outbreak, the SARS-CoV-1 virus was prevented from causing a pandemic of Severe acute respiratory syndrome (SARS). Rapid action by national and international health authorities such as the World Health Organization helped to slow transmission and eventually broke the chain of transmission, which ended the localized epidemics before they could become a pandemic.
Part of managing an infectious disease outbreak is trying to delay and decrease the epidemic peak, known as flattening the epidemic curve. [1] This decreases the risk of health services being overwhelmed and provides more time for vaccines and treatments to be developed. [1]
Walking pneumonia, a less severe form of pneumonia, is primarily caused by mycoplasma pneumoniae. The bacteria can damage the lining of the respiratory tract, including the throat, windpipe and lungs.
The ability to spread more easily from person to person appears to be the superpower that is driving an upstart sibling of the Omicron variant into wide circulation, a group of scientists has ...
The new findings reveal that understanding airflow patterns is even more crucial than simply increasing air changes per hour. During the COVID-19 pandemic, the common advice was to maximize ventilation, but this may not always be the most effective approach. A room can be well-prepared to prevent the spread of infectious diseases even at a low ACH.
Compared with previous variants, does it spread more easily, cause more severe cases and have the potential to evade COVID-19 vaccines? What we know about Omicron so far, according to an ...
