An accurate count of COVID-19 deaths is critical both scientifically and politically.

Taking into consideration the number of excess deaths caused by COVID-19 compared with pre-pandemic years is critical to getting an accurate accounting of the pandemic’s real toll.
Nearly all the wastewater samples from aircraft arriving in the UK showed evidence of COVID-infected passengers on board.
The northern hemisphere has seen a surge in winter viruses.
A couple of theories are popular for explaining why we’re currently seeing very high levels of respiratory viruses, but they’re not based in science.
Many viruses interact with the olfactory system, and can damage other areas of the brain through it.

Inflammation and damage to the olfactory system from shingles, COVID-19 and herpes infections may contribute to Alzheimer’s disease.
XBB.1.5 is rapidly spreading across the globe and will likely become the next dominant COVID-19 subvariant.
The XBB.1.5 subvariant — nicknamed ‘Kraken’ — is arguably the most genetically rich and most transmissible SARS-CoV-2 Omicron subvariant yet.
XBB.1.5, or ‘kraken’, can evade our immune systems better than earlier variants, and appears to be more infectious. But it’s not cause for alarm.
After a year of omicron variants, will we ever see a new variant of concern?
Nasal vaccines for COVID-19 are still in early development.

An effective nasal vaccine could stop the virus that causes COVID-19 right at its point of entry. But devising one that works has been a challenge for researchers.
Some results of independent testing of rapid antigen tests available in Australia have been made public. Here’s what the data tell us.
Researchers are revisiting old drugs and designing new ones to prevent and treat COVID.
Here’s what needs to happen next for our health systems to cope with the latest COVID wave.
The evidence so far suggests this wave could be a shorter and smaller version of the Omicron BA.5 wave.
Two new omicron variants seem to be waiting in the wings to usurp BA.5. Here’s what we know about BQ.1 and XBB.
Model of an influenza virus. Flu season is expected to make a big comeback this year.
Flu and COVID-19 are expected to make headway during the current respiratory virus season. The best way to stay healthy is vaccination in conjunction with personal protective measures.
These types of vaccines could offer certain advantages over conventional COVID shots. But we need more data to show us they’re effective.
There are so many forms of the virus, it’s hard to keep up. Here’s what to expect next as the virus mutates and recombines.
Two new omicron subvariants, BQ.1 and BQ.1.1 could lead to another COVID surge. Here’s what we know so far.
Red mitochondria in airway cells become coated with green SARS-COV-2 proteins after viral infection: Researchers discovered that the virus that causes COVID-19 damages lungs by attacking mitochondria.
COVID-19 causes lung injury and lowers oxygen levels in patients because the SARS-CoV-2 virus attacks cells’ mitochondria. This attack is a throwback to a primitive war between viruses and bacteria.
A recent preprint suggesting SARS-CoV-2 came from a lab has reignited the fierce debate over the origins of the virus.
New research adds to scientists’ understanding of how invading pathogens can change the way our genes switch on and off.
