Ready to have your perspective on viruses completely transformed? We often think of them as tiny, invisible enemies that make us sick. But what if I told you there's a whole other side to these microscopic marvels? A world of beauty, complexity, and even surprising partnerships? Let's dive into the fascinating world of viruses, just in time for the holidays, with a creative twist: papercraft snowflakes!
Many viruses are actually quite beautiful, resembling snowflakes in their intricate designs. The MRC-University of Glasgow Centre for Virus Research has created a set of papercraft virus snowflakes, which you can print and cut out. This is a fun way to explore the viruses around us this winter – and the vaccines that protect us from them.
Here's a festive countdown of some of our favorite viral wonders:
On the first day of Christmas, a virus gave to me: a world that is too small to see. Behold the adenovirus, a marvel of design, measuring a mere 100 nanometers across – that's smaller than a wavelength of visible light! Think of it as a tiny, perfectly formed ornament.
On the second day of Christmas, a virus gave to me: two twinned capsids. Geminiviruses, found in plants, showcase a clever trick: they stack their proteins into a doubled capsid structure. It's like a viral set of Russian nesting dolls.
On the third day of Christmas, a virus gave to me: three genome segments. While most viruses keep their genes in one piece, some, like the Heartland virus, split them into segments, similar to our chromosomes.
On the fourth day of Christmas, a virus gave to me: four COVID vaccines. Here, we celebrate the amazing progress in vaccine development, including protein subunit vaccines, inactivated virus vaccines, mRNA vaccines, and adenoviral vector vaccines. Each vaccine type represents a different approach to fighting the virus.
On the fifth day of Christmas, a virus gave to me: FIIIIVE TIIINY RIIIIIIINGS. Meet the anelloviruses, extremely common blood-borne viruses with circular genomes. Despite infecting almost everyone, they often go unnoticed, highlighting the complex relationship between viruses and their hosts.
On the sixth day of Christmas, a virus gave to me: six wasps a-laying. This is where things get a little bizarre. Bracoviriforms have a remarkable partnership with wasps. The wasp passes the virus's genes to its offspring, and the virus provides capsids. The wasp then uses those capsids to disable a caterpillar’s immune system, allowing it to lay eggs inside the living caterpillar. Nature can be a bit brutal, right?
On the seventh day of Christmas, a virus gave to me: seven dogs a-barking. We're talking about the rabies vaccine, made from inactivated rabies virus particles. This vaccine is a testament to early medical innovation, offering protection even after exposure to the virus.
On the eighth day of Christmas, a virus gave to me: eight tools for teaching. Bacteriophage lambda, which infects E. coli bacteria, has been instrumental in helping scientists understand how cells and genes are controlled. It's a reminder that even viruses can be incredibly useful.
On the ninth day of Christmas, a virus gave to me: nine childhood vaccines. From January 1, 2026, children in the UK will be offered free vaccines against nine viruses: measles, varicella zoster, poliovirus, mumps, hepatitis B, human papillomavirus, influenza, rotavirus, and rubella. This is a huge step forward in protecting public health.
On the tenth day of Christmas, a virus gave to me: ten lunar landers. Bacteriophage T4, one of the most complex bacterial viruses, lands on a bacterium like a tiny lunar module, injecting its genome.
On the eleventh day of Christmas, a virus gave to me: eleven Christmas dinners. This depicts a wreath of crAssviruses, which infect gut bacteria, surrounding a norovirus, which causes winter vomiting disease. It's a reminder that not all viruses are bad, and some are even part of a healthy microbiome.
On the twelfth day of Christmas, a virus gave to me: twelve fights worth winning. This represents viruses from major outbreaks since the start of the 20th century, including influenza, SARS-CoV-1, SARS-CoV-2, Zika, mpox, HIV, polio, and Ebola. The responses to these outbreaks were complex, but the tireless work of healthcare professionals, scientists, and public health specialists made a huge difference.
But here's where it gets controversial... The article mentions "disease X," a hypothetical disease that could be the next major outbreak. This highlights the ongoing need for research and preparedness.
