Influenza

Influenza (the flu) is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. The best way to prevent the flu is by getting a flu vaccination each year. Every year in the United States, on average 5% to 20% of the population gets the flu; more than 200,000 people are hospitalized from flu complications, and; about 36,000 people die from flu-related causes. Some people, such as older people, young children, and people with certain health conditions, are at high risk for serious flu complications.

Types of Influenza

Influenza is caused by three types of RNA viruses called influenza types A, B and C (considered different genera), which all belong to the family Orthomyxoviridae. The disease, colloquially called "flu" in humans, is generally caused by the viruses A and B, which are transmitted by aerosols from infected individuals or via close contact with infected animals.

Researchers identify genetic codes of COVID-19 and SARS viruses that may promote their lifecycles

Researchers have identified specific portions of the genetic codes of the COVID-19 and SARS viruses that may promote the viruses' lifecycles. The new technique is researchers' first tool for determining what genetic sequences stored as RNA - DNA's chemical cousin - are more stable.

Ciheb awarded $4 million to support COVID-19 response activities

The Center for International Health, Education and Biosecurity at the University of Maryland School of Medicine's Institute of Human Virology was awarded $4 million from the U.S. Centers for Disease Control and Prevention to support coronavirus disease 2019 (COVID-19) response activities in Botswana, Nigeria, Malawi, and Mozambique.

Specific immune suppression leads to severe COVID-19 disease

A new study published online on the preprint server medRxiv in May 2020 reports that specific changes in the way the human immune system responds to COVID-19 determine whether the individual develops moderate or severe illness.

SARS-CoV-2 emergence could be due to genetic selection and recombination

Researchers have found that genetic selection and recombination could be behind the emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that leads to acute respiratory distress syndrome (ARDS) or COVID-19 disease. This research could explain COVID-19 pandemic and its emergence. The study titled, “Emergence of SARS-CoV-2 through recombination and strong purifying selection,” was published in the journal Science Advances.

COVID-19 transmission unlikely to slow down dramatically during summer months

It is well known that rates of transmission of some respiratory viruses, including influenza, tend to fall during the summer months.

How susceptible are domestic animals to SARS-CoV-2?

A recent paper by Chinese researchers, published in the leading journal Science, shows that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) does not replicate well in dogs, pigs, chickens, and ducks; however, ferrets and cats are easily infected, and cats may transmit the virus via an airborne route.

Genomic variation and descent of SARS-CoV-2 strains in India

The pandemic of COVID-19 that is still affecting over 188 countries and territories the world over has taken over 359,000 lives in just under five months, while affecting at least 5.8 million people. Different strains have diverged from the original strain detected in Wuhan, China.

Research provides important insights into genetic adaptation of SARS-CoV-2 to humans

In their groundbreaking paper available on the preprint server medRxiv, University of Pittsburgh researchers were appraising signals of SARS-CoV-2 genome evolution and found that purifying selection (i.e., removal of deleterious mutations) represents the dominant trait during early coronavirus disease (COVID-19) pandemic - suggesting that the virus will evolve as it diversifies in a growing number of hosts.

Is air pollution a risk factor for COVID-19 infection?

The COVID-19 pandemic began at the very end of 2019 in Wuhan city, Hubei province, China. However, its spread soon began to threaten the health of the whole country and then of the world, leading to nearly 5.7 million cases and over 355,000 dead as of today. A new study, published on the preprint server medRxiv* in May 2020, explores the effects of air pollution on COVID-19 infections in China.

Preterm birth rates during COVID-19 in Denmark

The current COVID-19 outbreak was declared a pandemic in March 2020 by the World Health Organization (WHO). This led to the enforcement of a lockdown on an almost global scale with wide-ranging consequences. Now, a new Danish study published on the preprint server medRxiv* in May 2020 reveals the impact on preterm birth rates.

SARS-CoV-2 is uniquely adapted to infect humans

The novel coronavirus pandemic has sparked much debate on its origin, with some suggesting it may have been laboratory-grown. Previous studies, however, mentioned that it is zoonotic in nature, which means that the virus jumped from wild animals and found its way to humans.
