    Well, maybe the men are still interested at 80, but the women?

    My Neapolitan grandmother in law told me to do like she did when the time came; after menopause she told Joe the shop was closed and told him to sleep in one of the empty kids' rooms. She also looked at the wine bottle to make sure he only had one glass per meal, and he had to smoke his cigars on the porch because she couldn't stand the smell. Meanwhile, she smoked Camels or Lucky Strikes or some god awful thing.

    Who says Italian men always rule the roost in their homes? She'd be very disappointed in me. I'm a door mat compared to her.

    Seriously, in the U.S. anyway there's a lot of venereal disease in 55+ communities, or so the media says, so who knows if it's true. Oh, the unintended consequences of Viagra. Poor women. There's hormones for women too, for the ones who need it, but if I believe my friends many more women than men are less interested. Plus, what about your joints? What a way to break your hip. No way, Jose. Old goats. If I were ever going to change the habits of a lifetime and become promiscuous in my older years, he'd have to be not a day over 40, beautiful, and built or forget about it.

    He's enough to set my heart pitter pattering just looking at photos. :).

    Seriously, you're kissing the other person on the mouth, right? So, what difference does it make if you transfer it the other way too?

    No
    I mean all under 50 years asymptomatic ones, who run for 'holidays'.
    and then infect the 80 years old ones.

    The Villages retirement community in Central Florida is an over 55 community. It has the highest VD rate in the US. The old goats don't sheath their sword anymore since they don't have to worry about getting anybody pregnant but they forgot about venereal diseases.

    This is getting worse and worse...you mean the under 50s are going home to have sex with 70 and 80 year olds??? Even if it were Daniele Pecci that would be just too...weird. Old enough to be your son is bad enough, but grandson?

    No, wait, I get it. They're infected on vacation through sexual contact and then kiss grandma hello on the cheek when they get back. Whew! That's a relief. My dear Yetos, I was starting to wonder about you. :) Well, actually, I guess it's me who has a dirty mind. Oh, dear.

    I'll repeat, though. If you're kissing them "passionately" on the mouth you're already infecting each other, so what does it matter if it passes the other way too?

    That said, I don't know if it can be passed through intercourse.

    The damn thing is trying to take all our physical pleasure in each other away, and now even our grief.

    It has to be rooted out for ever.

    This is for SARS-CoV that caused the outbreak in 2003. Is this also a feature found in SARS-CoV-2?

    Sorry, true, it was about SARs 1.

    I could not find a clear message about COVID-19
    It seems that some patients may shed coronavirus through tears but few of them. Chinese research of Feb 2020
    "Evaluation of coronavirus in tears and conjunctival secretions of patients with SARS-CoV-2 infection "
    https://www.researchgate.net/publication/339511913_Evaluation_of_coronavirus_in_tears_and_c onjunctival_secretions_of_patients_with_SARS-CoV-2_infection

    Results: 21 common type and 9 severe type NCP patients were enrolled. Two samples of tear and conjunctival secretions were obtained from the only one patient with conjunctivitis yielded positive RT-PCR results. 58 samples from other patents were all negative.

    "He contracted the virus after seeing an asymptomatic glaucoma patient who eventually developed fever and respiratory issues [15][16][17] . This was followed by many focused studies to estimate the frequency and spectrum of different ocular complications associated with COVID-19 [18][19][20][21][22] . However till now no systematic review and meta-analysis has been done to and Medical Subject Headings (MeSH) terms. ...

    ... Our study is the first to provide and detailed account of ocular manifestation and RT-PCR positivity of tear/conjunctival swab samples in case of COVID-19.Virus shedding through tear mandates the personal protective equipments (N95 masks, goggles, head cover, protective gowns, gloves, shoe cover, alcohol hand sanitizer, surface cleaning) by ophthalmologists and health care workers 19,46,47 as recommended by American academy of ophthalmology 48 and Royal college of ophthalmology 49 "

    Overall, I'm sort of tired of finding yet another threatening news so it would be much better to find out how to pass immunity to this virus. It would be wonderful if antibodies could be passed to another person equally as easy as the virus spreads itself.

    Medical professionals wear face guard masks which protect their eyes as we know that COVID-19 could be aerosol-transmitted, and the tiny particles that carry the virus stay in the air for few hours. If the tiny particles carrying the coronavirus get into the eye, you get infected with the virus.

    In general, when a person coughs or sneezes, germs travel about 6 feet, while they can travel much farther to 20 feet away by breathing
    heavily in a gym and talking or singing loudly. Breathing the same air with a virus carrier in a closed space can get you infected with the coronavirus. The following study by Santarpia et al. (2020) looked into SARS-CoV-2's airborne transmission.

    Abstract
    Lack of evidence on SARS-CoV-2 transmission dynamics has led to shifting isolation guidelines between airborne and droplet isolation precautions. During the initial isolation of 13 individuals confirmed positive with COVID-19 infection, air and surface samples were collected in eleven isolation rooms to examine viral shedding from isolated individuals. While all individuals were confirmed positive for SARS-CoV-2, symptoms and viral shedding to the environment varied considerably. Many commonly used items, toilet facilities, and air samples had evidence of viral contamination, indicating that SARS-CoV-2 is shed to the environment as expired particles, during toileting, and through contact with fomites. Disease spread through both direct (droplet and person-to-person) as well as indirect contact (contaminated objects and airborne transmission) are indicated, supporting the use of airborne isolation precautions.

    Although this study did not employ any size-fractionation techniques in order to determine the size 25 range of SARS-CoV-2 droplets and particles, the data is suggestive that viral aerosol particles are produced by individuals that have the COVID-19 disease, even in the absence of cough. First, in the few instances where the distance between individuals in isolation and air sampling could be confidently maintained at greater than 6 ft, 2 of the 3 air samples were positive for viral RNA. Second, 66.7% of hallway air samples indicate that virus-containing particles were being 30 transported from the rooms to the hallway during sampling activities. It is likely that the positive air samples in the hallway were cause by viral aerosol particles transported by aersonnel exiting the room (16,17). Finally, personal air samplers worn by sampling personnel were all positive for SARS-CoV-2, despite the absence of cough by most patients while sampling personnel were present.

    The immunity response to SARS-CoV-2 may depend on genetics. https://www.wired.com/story/why-does...ask-their-dna/
    Some articles cautiously mention that the same gene mutation that makes people less susceptible or immune to HIV and bubonic plague may help to undergo COVID-19 in a very light form.
    The gene mutation is called CCR5 delta 32
    The Geographic Spread of the CCR5 Δ32 HIV-Resistance Allele https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1255740/

    The gene mutation is not that common (at least in homozygous carriers who happen to have two copies of the mutation), so it may not be very important in terms of statistics, but still it may have influenced the course of the disease.

    Britain and Belgium would be a bit of an anomaly, but I'm inclined to give it some credence. A paper I posted on the other thread also found some support for this, at a figure of about 50%.

    It would certainly be an important factor, if not the whole story.

    Not buying it yet. Britain, Belgium and Sweden have had plenty of deaths. I need to see statistics on how many contracted the virus, how many had no symptoms, how many developed light symptoms, how many more severe symptoms and how many deaths by age and underlying conditions.

    Talking about Sweden, here's an article on how they managed their response without a lockdown.

    The most relevant genetic factor in coronavirus transmission is the gene coding for the cell surface protein angiotensin-converting enzyme 2 (ACE2), which the coronavirus uses to enter airway cells. Variations in the ACE2 gene that alter the receptor could make it easier or harder for the virus to get into cells. The ACE2-expressing cells in lung tissues are more pronounced in East Asians than other populations, according to the new study published in Nature, which may suggest different susceptibility to SARS-CoV-2 from different populations under the similar conditions. Fig. 1c shows Africans are more susceptible to Covid-19 than Caucasians but less susceptible to Covid-19 than East Asians. Allele frequencies of ACE2 could be much lower among Scandinavians and more research is needed.



    Fig. 1: The coding-region variants and eQTL variants for ACE2 in East Asian and other populations.

    In summary, we systematically analyzed coding-region variants in ACE2 and the eQTL variants, which may affect the expression of ACE2 using the GTEx database to compare the genomic characteristics of ACE2 among different populations. Our findings indicated that no direct evidence was identified genetically supporting the existence of coronavirus S-protein binding-resistant ACE2 mutants in different populations (Fig. 1a). The data of variant distribution and AFs may contribute to the further investigations of ACE2, including its roles in acute lung injury and lung function12. The East Asian populations have much higher AFs in the eQTL variants associated with higher ACE2 expression in tissues (Fig. 1c), which may suggest different susceptibility or response to 2019-nCoV/SARS-CoV-2 from different populations under the similar conditions.

    Airborne transmission?

    Study is from China, so...

    See:
    https://www.nature.com/articles/s41586-020-2271-3

    Be cautious of bathrooms and get the air cleaned somehow.
    The ongoing COVID-19 outbreak has spread rapidly on a global scale. While the transmission of SARS-CoV-2 via human respiratory droplets and direct contact is clear, the potential for aerosol transmission is poorly understood1–3. This study investigated the aerodynamic nature of SARS-CoV-2 by measuring viral RNA in aerosols in different areas of two Wuhan hospitals during the COVID-19 outbreak in February and March 2020. The concentration of SARS-CoV-2 RNA in aerosols detected in isolation wards and ventilated patient rooms was very low, but it was elevated in the patients’ toilet areas. Levels of airborne SARS-CoV-2 RNA in the majority of public areas was undetectable except in two areas prone to crowding, possibly due to infected carriers in the crowd. We found that some medical staff areas initially had high concentrations of viral RNA with aerosol size distributions showing peaks in submicrometre and/or supermicrometre regions, but these levels were reduced to undetectable levels after implementation of rigorous sanitization procedures. Although we have not established the infectivity of the virus detected in these hospital areas, we propose that SARS-CoV-2 may have the potential to be transmitted via aerosols. Our results indicate that room ventilation, open space, sanitization of protective apparel, and proper use and disinfection of toilet areas can effectively limit the concentration of SARS-CoV-2 RNA in aerosols. Future work should explore the infectivity of aerosolized virus.
