DNA viruses have a genetic structure composed of DNA and include single-stranded and double-stranded types. They enter cells and hijack them, forcing them to produce viral material. Treatment includes vaccination and drugs to block viral replication, but developing effective antiviral drugs can be challenging due to the small size of viruses. DNA viruses are infectious […]
Cancer viruses are known to alter cell composition, increasing the risk of developing tumors. DNA and RNA viruses can cause cancer, but not in every person. HPV, herpes, Epstein-Barr virus, and hepatitis B are examples of DNA viruses that can cause cancer. Hepatitis C and human T lymphotrophic virus type 1 are RNA viruses that […]
Encephalitis is an inflammation of the brain caused by viruses, including herpes simplex, Epstein Barr, varicella-zoster, and arboviruses spread by ticks or mosquitoes. Vaccinations and protective clothing can prevent infection. There are several types of encephalitis viruses. Encephalitis is an inflammation of the brain that can cause mild or more severe, life-threatening flu-like symptoms, such […]
Spyware and viruses are both types of malware that harm software or files, but they spread differently. Spyware hacks into computer activities and sends user information to third parties, while viruses create copies of themselves and try to spread to other computers. Spyware is often bundled with other files or programs, while viruses are spread […]
Computer viruses spread through the internet, networks, and removable devices. Windows is the most targeted operating system, while Apple systems are less likely to be infected. Precautions include not opening suspicious email attachments or links, downloading antivirus software, and backing up data. Warning signs of infection include slow performance, frequent freezes or shutdowns, and unusual […]
To protect your computer from viruses, use antivirus software, keep your operating system and software up to date, use a secure internet connection and firewall, and avoid installing untrustworthy software or opening unknown emails. Consider using a less vulnerable browser and operating system. Scan incoming mail and discs for viruses. Many computers, especially those running […]
Viruses are not technically alive and require a living cell to multiply. Dead viruses can be used to find cures for live viruses and confer immunity to certain diseases through vaccination. There is no evidence to suggest vaccines cause autism. Polio remains endemic in three countries, weak public health systems are at risk, and the […]
The first artificial virus, a Phi-X174 bacteriophage, was synthesized in 2003 by Craig Venter’s team. The process involves synthesizing oligonucleotides, purifying them, assembling them, and making copies using PCR. The synthesized virus was infectious and could be used for pollution abatement, but there is a risk of misuse. The world’s first artificial virus was synthesized […]
Viruses are small genetic materials that can hijack cellular machinery for replication. Virologists monitor around 30,000 types of viruses, but there are probably millions. The International Committee on Taxonomy of Viruses developed a unified taxonomy in 1966, and the Baltimore Classification is commonly used in conjunction. Traditional classification is based on the type of organism […]
Gastrointestinal viruses, including norovirus, rotavirus, adenovirus, sapovirus, and astrovirus, cause stomach flu or gastroenteritis. Symptoms include vomiting, nausea, stomach pain, and diarrhea. Prevention measures include hand washing and avoiding crowded areas. Medical care should be sought if symptoms persist. Gastrointestinal viruses are the most common culprits behind the stomach flu or gastroenteritis. These insects inflame […]
