Viral diagnostic tests are categorized as direct diagnosis, indirect examination (virus isolation), and serology. Molecular testing is often done to detect potent viral markers resulting from any gene or chromosomal modifications during viral replication in the host. The clinical specimen is tested specifically in direct analysis for the presence of virus particles, virus antigens or viral nucleic acids. Molecular diagnosis of viruses can be achieved from clinical samples like blood, hair, skin, amniotic fluid, or other tissue. Molecular biology techniques are considered to be the standard and confirmatory protocols in the analysis of viral DNA, RNA and protein. Molecular viral diagnosis are considered to be more specific and sensitive in preliminary viral screening and can pave the way for rapid diagnosis. However, the procedures are costly and involve automated bio-instruments to perform the same. This review thus highlights the various molecular diagnostic methods used in diagnostic virology with their limitations and challenges.

A virus is composed of nucleic acid either DNA or RNA, surrounded by a protein coat.It requires a living cell to multiply. A viral infection can lead to a spectrum of symptoms from asymptomatic to severe disease.Worldwide,5% of health-care-related infections are being transmitted. Dentists are considered being a high risk group for cross-infection.Therefore it is important that dental students have adequate knowledge and awareness of viral infections.The aim of the study is to evaluate the knowledge, awareness and attitude about oral manifestations of viral infections among dental students.A self explanatory questionnaire comprising 20 questions was presented to 205 students. The questionnaire enquired about oral manifestations of different viral infections and their precautionary infection control measures .Out of 205 students 86.34% were males and 13.66% were females,189 of them knew that the most common oral manifestation in HIV patients is candidiasis.92.6%agreed that a dentist could get Herpetic paronychia.When asked if treatment of patients with viral infections required special clinics 68.1% responded yes.Our study showed that the dental undergraduate students had adequate knowledge on oral manifestations of viral diseases but lacking knowledge about infection control protocol for the various diseases. Hence students should improve their attitude towards them in their dental practice.

Viruses cause familiar infections and diseases like common cold, flu. They invade living, normal cells and use those cells to multiply and produce colonies of cells.Viral infection is a proliferation of harmful viruses inside the body. Viruses infect the host body by introducing their genetic material into the cells. The main aim of this study is to explore detailed information about saliva and viral infections. This research is seen as a scoping literature review. In seeking to identify the relevant articles, we used common databases such as the Pubmed and Google scholar online websites. Totally 27 articles are found related to the topic. 12 articles are used in this study. From the articles collected and reviewed, it is understood that viral infections can transmit through the saliva and oral specimens, though saliva protects the body from infections. It is concluded that, as saliva has become the transmitter of the virus, we should maintain proper oral hygiene and oral health to prevent these viruses. Future studies have to be done on the viral infections causing cancer.

Influenza is an infectious disease caused by Influenza virus. Symptoms may include- fever, cough, headache, sore throat muscle and body pain and fatigue. These symptoms begin two days after exposure to the virus and most last less than a week. Old age people and children are at great risk due to this virus. Complications of influenza may include viral Pneumonia , secondary bacterial pneumonia sinus infections and worsening of previous health problems such as asthma or heart failure. Influenza spreads around the world in yearly outbreaks, resulting in about three to five million cases of severe illness and about 290,000 to 650,000 deaths. Three of the four types of influenza viruses affect humans : Type A, Type B, and Type
C. Type D has not been known to infect humans, but is believed to have the potential to do so. In this present study, data was collected and was verified using a standard software. Statistical analysis was done with the help of SPSS software and representation was done using pie charts and graphs. Data was entered and verified using a standard computer software. Type of analysis used was chi square. It was concluded that a maximum number of awareness was shared about the influenza, its causes, symptoms and risk factors associated with it.
